How to use Track QR

Create QR tags for your belongings, print them and keep information and events in one place.

Get started

A QR tag is a QR code that opens a page in Track QR. People who scan it can view information about the tag and, if its settings allow it, add an event or a comment.

Select Create a new account if you do not have an account, and follow the registration instructions.
Log in with Sign in or choose Use Google Sign in if it is enabled for your account.
Select Create new tag to create your first tag.

Create a QR tag

Open Create new tag and select a category. The category controls settings such as visibility, who can add information and notifications.
Select Single tag, enter all information now, then Next.
Enter a Name, such as “Blue backpack”. Add Custom info. and Notes if needed.
Check Contact info (printed on tag). This text will appear on the printed tag.
Choose your preferences under Notifications. Same as category uses the category’s setting.
For an encrypted tag, follow the encryption instructions below before creating it.
Select Create. A print page or PDF opens in a new tab.

Creating a single tag with example information. Select encryption before creating the tag if needed.

Create several tags at once

Select Multiple tags, print now, enter the information after scan to print tags first and add their information later. You can create up to 25 tags at a time, within your account’s available quota.

Fill in and check blank tags before putting them into use. Sign in to the account that owns the tags to edit their information. Only the owner can edit a tag, even when it has no title.

Creating multiple tags — Preparing six tags with shared contact instructions. No personal owner details are included in this example.

Encrypted tags

Use encryption when you want tag details and posts to be readable only by people who have the tag password or full tag link. Category access restrictions still apply.

Create and keep access to an encrypted tag

In the creation form, select Encrypt tag information and new events.
Select Automatically save new tag passwords in this browser if you want passwords saved after successful creation. The choice is remembered per account in this browser and applies to all tags in a batch. Leave it unchecked on shared devices.
Each tag automatically gets its own random password, even when creating multiple tags. You cannot choose a custom password. Existing tags keep their original passwords.
Create the tag and keep its full link, printed QR code or password somewhere safe. Track QR cannot recover a lost tag password.
On your own device, you can select Save password in this browser. Open QR-tags → Handle local data to manage saved passwords and make a backup.

Manage saved tag passwords

Under QR-tags, select Handle local data. The menu lists passwords saved in this browser for the signed-in account, with matching tag numbers from your account. Passwords without a matching tag are listed as Unmatched tag. Older tags may share a password. Newly created tags each have a separate password.

Show / Hide reveals or hides an individual password.
Export downloads one password as a JSON file. Export all downloads all saved tag passwords, including unmatched ones, and local contact details when present. Matching tags include their tag numbers and full links.
Import restores passwords from a previously exported JSON file, for example in another browser or on another device. It adds missing passwords and local contact details while keeping existing copies without overwriting them.
Remove unmatched passwords appears when saved passwords have no match among your account’s tags. The service checks all your tags again before removal. Unmatched entries may belong to imported backups or other people’s tags: use Export all first if you might need them. Confirmation is required, and removals reach the vault and other devices on the next sync. Matching passwords and local contact details are kept.
Remove deletes one saved password from this browser. Remove all deletes all saved tag passwords after confirmation. Neither action changes the passwords on the tags or locks already open tabs. If you sync with the vault, saved-password removals also propagate to the vault and other devices when they sync.

Export files contain readable passwords, may contain local contact details and may include full links that unlock your tags. Keep backups private. Before removing a saved password, make sure you still have its backup, original QR code or full link. Signing out does not erase saved passwords.

Open, read and lock

A full tag link includes the password and normally unlocks the content automatically. If you open a link without the password, enter it and select Unlock. Signing in as the owner does not replace the tag password.

Lock again clears the unlocked text, image and unsaved edits in this tab. It does not remove a permanently saved password; use Remove saved password for that. Signing out does not erase saved tag passwords. The password-saving control and full-link shortcut are shown only to the tag owner.

Locked example tag with password field and Unlock button — A locked tag. Enter its password and select Unlock to read the protected information.

What is protected?

Tag details and a post’s text, email and coordinates are encrypted in the browser. Tag names are also encrypted. Tag identifiers, account identity, event type and time remain unencrypted. Images use a separate process: the server receives the image over HTTPS, encrypts it and keeps an unencrypted copy for administrator review. See Tag images below. For details about data handling, see the privacy policy.

Anyone with the full QR link or password who can access the encrypted content can read it, including email addresses inside posts. Treat the printed QR code as a way of sharing access. Recipients can copy or pass on the link, password or information.

Delete your encrypted posts later

If you post while signed in, use your posting account to manage the post. Guests can manage posts during their original session. To retain access by email, provide an email address and select Allow me to delete this post later by verifying my email before saving.

Later, open Your posted information, enter that address, complete the captcha and request a verification link. If the address belongs to an existing account, sign in to that account instead. After verification, select your posts and use Delete selected. Deletion does not require the tag password; reading or editing encrypted content does.

Email recovery is optional and stores a protected email fingerprint separately from the encrypted content. Knowing a tag password alone does not give you author access to other people’s posts.

Encrypted post form with the option to delete the post later by verifying an email address — The email recovery option appears below the posting consent. Enable it before saving if you want to manage the post later through email verification.

Sync local data between devices

Saved tag passwords and optional local contact details are encrypted in browser storage and kept separate for each account. The local encryption key is held by your account on the server. A vault provides a separate encrypted copy for syncing between devices, protected by its own password.

Open QR-tags and select Sync now to open Encrypted local data sync.
For first-time setup, choose and repeat a separate vault password of at least 12 characters. This is not your account password or a tag password.
Select Continue to recovery key. Save the recovery key somewhere safe outside this browser, confirm that you have saved it, then select Create vault and sync.
On another device, sign in to the same account, open Sync now and enter your vault password to sync the saved data.

Choose how to sync

Under Sync settings, choose a mode and select Apply settings. Browsing the list does not change the active setting:

Manual sync: sync only when you select Sync now.
Automatic sync — 8 hours: enter your vault password and select Sync now. Sync continues across page reloads in the same tab for up to eight hours. Closing the tab normally ends remembered access; browser session restoration may preserve it.
Automatic sync — 30 days: enter your vault password and select Sync now. The browser remembers access for up to 30 days. Enable Keep me signed in at sign-in to continue after closing the browser.

Automatic modes sync saved changes and removals while unlocked. Offline changes wait for a connection, and conflicts require your choice. Applying a different mode locks the vault; select Sync now with your vault password to start again. Signing out or Lock vault ends remembered access.

Use the 30-day option only on a private device. Anyone using your signed-in browser may access the vault without its password. The remembered vault key is encrypted with your server-held account key; this offers less protection than entering the separate vault password each time. Website scripts or a compromised server may access it. The vault password itself is never saved.

Recovery, reset and local key changes

Open Recovery and vault management in the sync dialog for recovery, replacement recovery keys and vault reset. If you forget the vault password, use the recovery option with your recovery key and a new vault password. If you still know the password but have lost the recovery key, use Create new recovery key and follow the save-and-activate steps.

If both are lost, Reset vault… requires typing RESET. It removes the current server vault contents and allows a new setup; it does not recover the lost contents. Existing locally saved tag passwords remain available. Back up any accessible local data before resetting.

Change local encryption key under Handle local data re-encrypts this browser’s saved data and locks the vault, clearing remembered vault access. Unlock the vault again to resume sync. Other devices must restore their local copies by importing a backup or unlocking and syncing the vault. It does not change tag passwords or the vault password.

Local encryption protects stored browser copies, not information already unlocked on screen or scripts running in a signed-in page. Keep exported files, full tag links and recovery keys private.

Keep personal contact details locally

Open Account and enter your optional personal contact details.
Select the option to store contact details only locally, then save. The browser saves an encrypted copy before the corresponding server account fields are cleared. A padlock appears beside those fields after saving.
Use vault sync or Export all in Handle local data to keep a copy for another device or recovery.

This option is suitable only if you use encrypted tags. Your sign-in email stays on the server, and existing details already copied into tags or printed labels are not removed. Turning the option off and saving stores the displayed details on the server again.

When creating an encrypted tag, owner information can be filled from the local profile according to the category’s visibility settings. Use Use owner information to fill Contact info (printed on tag), and check the text before printing. Printed text can be read by anyone who sees the label.

If a device has no local contact details, import a backup or sync with the vault, then reopen Account. Unencrypted tags cannot use the local profile.

Tag images

Only the signed-in owner can upload or replace an image on a tag. This applies to ordinary and encrypted tags. Having a tag’s full link or password does not grant upload permission. Blocked accounts cannot upload images.

Upload an image to an encrypted tag

Open your tag’s Edit view and unlock it with the full link or its saved password.
In the image section, choose a JPEG, PNG, GIF or WebP image up to 6 MB. The image is uploaded automatically. The server checks and resizes it.
The encrypted image can be viewed immediately after unlocking the tag. Image awaiting administrator approval. means its review is still pending.

The browser creates a separate key pair for each upload. It sends the public key and the image over HTTPS to the server, which encrypts the image. The private key is stored only in encrypted form, protected by the tag password. The browser decrypts the image when you unlock the tag, including on another device with the full link or password.

Encrypted image data is stored in access-protected files on the server, with encryption metadata in the database. The review copy remains in the database until approval or deletion.

Before approval: the server also keeps an unencrypted review copy that only an active administrator can open through the review page. It has no public image address.

Approved: the unencrypted review copy is deleted from active storage. The encrypted image remains available.
Rejected: both the encrypted image and its review copy are deleted.
Replaced: the replacement image must be reviewed again. Replacing an image uses the same image quota slot.

To remove your image, select Delete image and confirm. Cancel the confirmation to keep it. Deleting an encrypted tag’s image removes both stored copies if review is still pending. Deleting the tag also removes its stored image.

Image uploads are not end-to-end encrypted: the server receives the readable image for processing and review. Deletion applies to active storage; older backups and database logs follow separate retention routines.

Print and attach your tag

Open the PDF and print it. You can adjust the print settings under Pdf-settings. Measurements are in millimetres and font sizes are in points. Save your changes with Update.

Make a test print and check that the text is readable.
Keep the entire QR code and the light border around it visible.
Scan the printed code and check that it opens the correct tag.
Attach the tag to a flat, visible surface. Avoid creases, damage and reflections that make scanning difficult.

Printing encrypted tags

Encrypted tags are prepared in your browser. Unlock the tags when prompted, select Prepare tags if shown, then Print / Save as PDF. Use the browser’s print dialog to print or save a PDF. The QR codes include their passwords, and any readable text printed on the label is visible to anyone who sees it.

Browser print view with an encrypted example QR label — Browser printing for an encrypted tag. This example contains only demonstration information; its full QR link includes the example password.

Page layout and label fields

Under Pdf-settings, choose the page size, label spacing and fields to include on the printed labels. Owner information comes from your account; category settings control which details are included. Check the preview before printing.

PDF layout settings: page size, label dimensions and fields to include.

Download QR images

You can also download QR images in a ZIP file from QR-tags and use them in your own label layout. Keep each code with the correct item information and test it after printing.

Scan and add information

Open your phone’s camera or a QR reader and point it at the code.
Tap the link that appears to open the tag.
Read the tag’s information. If the New event form is shown, you can add an event.
Choose a type under Event, optionally enter your email address and write in Contact info/comment.
To share your location, select Provide position and allow location access when your browser asks. Select Clear position to remove it before submitting. Sharing your position is optional.
Follow the form’s instructions, complete any security check and submit your information.

For encrypted tags, unlock the tag before reading its protected content or submitting a post. To be able to delete a guest post after your session ends, enable the email verification option before saving; see Encrypted tags.

What you can see and do depends on the tag’s category. Some tags require you to sign in or have specific permission. If moderation is enabled, your post must be approved before it is published.

A QR tag does not transmit its location on its own. Any location shown comes from recorded information, for example when the tag was created or an event was added.

Manage tags and events

QR-tags: Find your tags here and open the one you want to work with. When editing a tag’s information, select Save to save your changes.
Event log: Follow events for your tags here.
Your posted information: View information you have submitted.
Create new tag → the category’s pencil icon: Change category settings, including which owner details are shown, who can view the tags and who can add information.

Edit an encrypted tag

Unlock the tag before editing its protected fields. Owner information is a separate encrypted copy of the owner details selected when the tag was created; later account or category changes do not update it automatically. Edit that copy here when needed. Contact is a separate field. In the tag’s reading view, the two are shown in separate paragraphs with bold labels.

Use Save for text changes. The image section below the fields handles image uploads and deletion separately. The password-saving button and Lock again appear once in Edit; locking clears both the text and the image from the unlocked view.

Change a tag ID

Open the tag’s Edit view and use Edit beside its identifier. A new ID must be unique and contain 10–22 characters, including uppercase and lowercase letters, a number and a supported special character. Use the random generator if you do not want to choose one yourself.

You can change the ID only when all events outside the trash belong to your account. Events in the trash are permanently deleted when the ID changes, which can affect notification counts. Old links and printed QR codes stop working after an ID change; download and print the updated codes.

Convert an existing tag

In Edit, select Convert to encrypted… or Convert to unencrypted…. Save any text edits first; conversion uses the currently saved tag. Unlock an encrypted tag before converting it.

Conversion includes the tag, its remaining events and its existing image. Only the owner’s events may remain outside the trash. Trashed events are permanently deleted during conversion, which may affect notification counts. An already approved image keeps its approval; an unreviewed image still needs review.

You can keep the ID or choose a new one: 10 characters when encrypting, 22 when removing encryption. Changing the ID breaks old links. Reprint encrypted QR codes with the new password when encrypting. The new password is automatically saved in encrypted browser storage before conversion; if saving fails, conversion stops.

Removing encryption makes the content readable by the server and viewers permitted by the category. Owner information then uses the current account and category settings instead of the encrypted owner-info copy. Encrypting does not erase previously shared plaintext copies or older backups.

Check and sync owner information

In QR-tags, filter for encrypted tags and use Unlock directly in the list. Once unlocked, the owner-info indicator shows whether the encrypted copy is missing or differs from the current account or local profile. Select Review / update to inspect it, or Sync to update it directly.

Sync all owner info appears when unlocked tags in the current view need updating. It updates those tags; locked tags and other pages must be checked separately. After changing your account contact details, check your encrypted tags. Owner-info sync does not replace the separate contact text printed on a tag.

Search encrypted information

Unlock the relevant tags or events first. Encrypted information can be searched only while unlocked in the current view; encrypted content on other pages is excluded. Event search also searches unencrypted email and contact information across all events. A missing result does not necessarily mean the tag or event does not exist.

Create or edit a category

Use categories to give a group of tags the same settings. You can change a tag’s category when editing the tag.

Owner information to include controls which account details people see after scanning. For a key tag, for example, leave out your home address and include only the instructions needed to contact you or return the keys.

Moderation lets you review new posts before they are published. Category notification settings provide defaults, which you can override for individual tags.

How long is an event visible?

In the category settings, Events controls how many events are displayed when a tag is scanned. Expire determines when an event is hidden from people scanning the tag. Delete determines when it is removed from the system.

The category also has settings for how many recent events to keep and a maximum event count. Review these alongside the age limit. A display limit is not the same as deletion: the owner can view retained events in the account, but deleted events are no longer available. Changes to the deletion age apply to new events.

Disabling scan events excludes scans from the tag’s event history. Reloading a tag does not necessarily create another scan event, so the event history is not a count of every page view.

Check which contact details the category displays and what information you print on the label before sharing or attaching the tag.

Notifications

Notifications can be controlled by both the category and the individual tag. Options include turning notifications off, receiving event notifications and including scans. There is also an option for scans when a tag is marked as lost or stolen.

Scanning your own tag while signed in does not send you a scan email notification.

For encrypted posts, notifications omit the encrypted text, email and coordinates. Encrypted tags are identified by tag number rather than name; the event type may still be shown. Open and unlock the tag to read the content.

If scan events are disabled for a category, scan notifications will not work for its tags. To receive browser notifications, you must also allow notifications for the website in your browser.

Account and sign-in

Open Account to manage your account. If you have enabled two-step verification, enter your security code in the Security code field when signing in.

If you cannot sign in, select Can't acccess your account? in the sign-in form. You will find Password recovery and Disable 2 factor authentication. Choose the appropriate option and follow the instructions.

On a shared computer, leave Keep me signed in and the option to skip the security code unchecked. Select Sign out when you are finished.

Frequently asked questions

Can I switch an existing tag between encrypted and unencrypted?

Yes. Open Edit and select Convert to encrypted… or Convert to unencrypted…. Save your edits first and unlock encrypted content before converting. All events outside the trash must belong to you. Conversion includes the remaining events and image, and permanently deletes trashed events. Approved images keep their approval. See Manage tags and events for the full instructions.

Will my old QR codes work after changing the ID or encryption?

Changing the ID breaks old links and QR codes. When converting to encrypted, use a new full link or QR code containing the new password, even if you keep the ID. Reprint your codes after conversion and check that they open the tag as intended.

Why can’t I change a tag’s ID or encryption?

Only the owner can do this, and events from other users or guests must first be moved to the trash. Those trashed events are permanently deleted during the change. To convert encrypted content, you also need to unlock it with the tag password.

Can new tag passwords be saved automatically?

Yes. Select Automatically save new tag passwords in this browser when creating encrypted tags. The choice is remembered for your account in this browser and applies to batches too. When converting an existing tag to encrypted, its new password is always saved in encrypted browser storage before conversion; conversion stops if that save fails. Keep a backup or sync your saved passwords with the vault.

Does closing an abuse report delete the reported content?

No. Close report marks the report as finished; it does not delete the tag or event. Administrators take moderation actions separately. Closed reports are removed from active storage after 90 days when the reporting system is next used.

Can I include web links in tags or events?

Web links are not allowed in tag text or event comments, including text written by the owner. Remove the web address if saving is blocked. Email addresses are allowed, but even the tag’s own link is blocked in text fields. Generated QR codes and tag links still work. Existing content is not automatically removed. For encrypted content, this check runs in the browser before encryption.

Are my account password, tag passwords and vault password the same?

No. Your account password signs you in, each tag password unlocks its encrypted content, and your separate vault password unlocks the synced collection of saved passwords and local contact details. Account password recovery does not unlock a vault or recover a tag password.

Does Remove all also remove passwords from the vault?

Yes, when the changes are synced. Other devices apply the removals when they next sync. This removes saved copies, not the tags or the passwords embedded in existing full links and QR codes. Export a backup first if you need to keep a copy.

Can several accounts use the same browser?

Saved local data is separated by account. Switching accounts clears temporary access to the previous account’s secrets; its persistent encrypted copies remain. Sign out on shared devices and do not leave decrypted information visible.

Why did sync stop after I reloaded?

Reloading locks the vault unless you unlocked using an automatic sync mode. Unlock again with your vault password. Tab unlock lasts up to eight hours; the private-device option lasts up to 30 days. Both require the same login.

What if my local data is missing or damaged?

Open Handle local data to import a backup, or unlock and sync your vault. A damaged local copy does not count as an intentional removal from the vault. After a local encryption key change, other devices also need to restore or sync their data.

Why do notifications show a tag number instead of its name?

Encrypted tag names cannot be read for notifications. Open and unlock the tag to see its name. Unlocked names can also be found using search in the current view.

Does deleting my account delete the vault?

Yes. Account deletion removes the server vault and the server-held local encryption key along with the account. It cannot recall downloaded exports, printed links or browser copies on other devices. Remove those copies yourself. Server backups follow the retention periods in the privacy policy.

Are encrypted tags end-to-end encrypted?

Protected text fields are encrypted in the sender’s browser and decrypted in the reader’s browser. The server stores ciphertext and does not receive the tag password through the normal creation, posting or reading flow. This provides end-to-end encryption of those content fields using the tag password. Images are different: they are uploaded over HTTPS, encrypted by the server and kept readable for administrator review until approval. See Tag images.

Anyone with the full tag link or password who can access the ciphertext can read it. Tag identifiers, account identity, event type and time are not covered by content encryption; tag names are encrypted. Optional email recovery creates a separate, matchable email fingerprint; it does not decrypt the content.

The browser still relies on JavaScript supplied by the website. A compromised website or device could capture passwords or decrypted information. Sharing a full link also shares access to the encrypted content.

Which encryption algorithms and key sizes are used?

The current implementation uses the browser’s Web Crypto API:

Content encryption: AES-256-GCM, with a 256-bit key and a 128-bit authentication tag that detects ciphertext tampering. Each encryption generates a fresh random 96-bit IV.
Password-based key derivation: PBKDF2-HMAC-SHA-256 with 600,000 iterations and a random 128-bit salt generated at creation. The salt is retained for subsequent posts and edits using that encryption context.
Generated passwords: 24 cryptographically random bytes, encoded as 32 URL-safe characters, providing 192 bits of randomness. Random values come from the browser’s crypto.getRandomValues().

New tags always use automatically generated passwords, with a separate password and salt for each tag in a batch. Existing tags keep their passwords; older custom passwords may offer less resistance to guessing. Keep generated passwords and full links private.

Technical references: AES-GCM parameters and PBKDF2 parameters.

Does email recovery use the tag’s encryption key?

No. The browser creates a SHA-256 fingerprint from the normalised email address and a recovery-specific prefix. The server protects it with HMAC-SHA-256 using a separate server secret. This supports email matching and verified post management; it is not content encryption and cannot recover the tag password. The service can match a supplied address to this fingerprint, so it should not be treated as anonymous data.

Can I choose my own tag password? Do tags created together share one?

Custom passwords are no longer offered. Every new encrypted tag gets its own random password, including when creating several tags at once. Each printed QR code includes the password for its own tag. Existing tags and their passwords are unchanged.

Who can upload or replace a tag image?

Only the signed-in owner, for both ordinary and encrypted tags. A full tag link or password grants no upload rights. The server checks ownership on every upload. Blocked accounts cannot upload.

Can I see my encrypted image before it is approved?

Yes. Unlock the tag to view it immediately. The pending-approval message remains until an administrator reviews it. Approval deletes the unencrypted review copy; rejection deletes both copies. Uploading a replacement starts a new review.

Does the server see an image uploaded to an encrypted tag?

Yes. The image is sent over HTTPS without browser-side image encryption. The server processes and encrypts it using the public key supplied by the browser, and keeps an unencrypted copy for review. The browser’s private key is stored only encrypted with the tag password. After approval, only the encrypted image remains in active storage; historical backups follow their own retention routines.

What is the difference between Remove saved password and Lock again?

Remove saved password removes the password saved permanently in this browser; it does not delete the tag or immediately lock this tab. If you sync with the vault, the removal also reaches the vault and other devices when they sync. Lock again hides the unlocked content and clears unsaved edits in this tab, but keeps any permanently saved password.

How do I delete a tag image?

Open the tag’s Edit view, select Delete image and confirm. This removes the image, including any pending review copy, without deleting the tag. Cancel the confirmation to keep the image.

Why does my encrypted tag ask for a password even though I am signed in?

Your account identifies you as the owner, but does not contain the tag password. Scan the original QR code, open the full tag link or enter the password. If you saved it in this browser, you can use that saved password to unlock the tag.

Can Track QR recover a lost tag password?

No. Check the original QR code or full link, a browser where you saved the password, an exported password backup, or your unlocked vault. Account password recovery and post email verification do not recover a tag password.

Can other people read encrypted posts on my tag?

Yes, if they have the full link or password and can access the content under the tag’s visibility settings. Encryption does not make posts readable only by the owner. This includes email addresses inside encrypted posts.

Why does email recovery say “No records found”?

For an encrypted guest post, the email recovery option must have been enabled when it was saved. Older posts have no recovery fingerprint unless it was added later. Use the original guest session or posting account if you still have access; you can then unlock and edit the post to enable recovery. Unlocking the tag alone does not restore author access.

Do I need the tag password to delete my post?

No, if you already have author access through your posting account, original guest session or an enabled email recovery link. Use Your posted information. The password is still needed to read or edit encrypted content.

Why can’t I save the password or see a full-link shortcut?

These controls are shown only to the signed-in tag owner. Guests can still unlock the content and use Lock again. Anyone with the original QR code can still copy its full link.

Why can’t I create more tags?

Your account may have reached its quota. Usage is shown under Create new tag. Also check that you are signed in and have selected a category.

Why doesn’t the PDF open?

Check whether the PDF opened in another tab or whether your browser blocked the new tab. Check QR-tags before creating the tag again to avoid duplicates.

Why won’t the QR code scan?

Check that the code is complete, sharp and large enough. Improve the lighting, avoid reflections and try a different distance. If a link appears but the page does not open, check your internet connection.

Why can’t I view a tag or add a post?

The category may restrict access to registered users, selected users or the owner only. Sign in with the correct account. The tag’s owner controls permissions.

Why isn’t my post visible?

Your post may require moderation. The number of visible events and the category’s time limits can also affect what is shown. If you are the owner, check Event log.

Why is no location shown?

Location access may be denied in your browser or on your device, or the category may not allow location information. Check your location settings and select Provide position to try again.

Why am I not receiving notifications?

Check the notification settings for both the tag and its category. Browser notifications must also be allowed for the website. If you are expecting an email, check your spam folder as well.

Can I delete a category that is in use?

A category used by tags cannot be deleted. Manage the affected tags first, then check the category again.

How can I report misuse of a tag or event?

Use Report abuse beside the tag information or event, select a reason and describe the issue. A contact email is optional, and you do not need an account. An administrator reviews reports; reporting does not automatically remove content or block an account. Do not include passwords, full tag links or unnecessary personal information. Encrypted content is not attached automatically, so describe the problem without sharing its password.
