Privacy Policy for WebTeX

1) What WebTeX Does

WebTeX detects math expressions on webpages and renders them using KaTeX.

All parsing and rendering happen on your device within Safari.

2) Data Collection

WebTeX does not collect, store, or share any personal information.

• No account, login, or identifiers
• No analytics or telemetry
• No ads, SDKs, or tracking
• No clipboard access or keystroke logging

3) Data Transmission

WebTeX does not send any data to external servers.

The extension operates entirely on-device; it only reads the current page’s content to locate math elements so it can render them.

Platform status: WebTeX is currently iOS-only and does not integrate with iCloud backups. As a result, any local extension data is not included in iCloud device backups and is not transmitted to Apple.

Future changes: If optional iCloud backup support is introduced in a future update, any backup and restore activity would be handled by iOS and your iCloud settings. In that case, data could be transmitted to Apple’s services solely for backup/restore and would be subject to Apple’s terms and privacy policy. We would not receive any of this data.

4) Permissions & Page Access

To function, WebTeX needs permission to read webpage content where you enable it.

This is used solely to find math expressions and render them with KaTeX. No content is persisted or transmitted by the extension.

5) Data Retention

WebTeX retains no data. When you close a page, there’s nothing stored by the extension.

6) Third-Party Libraries

WebTeX includes KaTeX (MIT-licensed) for local rendering.

KaTeX runs entirely on-device and does not send data anywhere.

7) Children’s Privacy

WebTeX does not collect information from anyone, including children.

8) Changes to This Policy

If this policy changes, we’ll update the text at this URL and adjust the “Last Updated” date.
