What it collects
Nothing. The extension has no account, no analytics, no tracking and no way to contact a server.
Privacy
Paste Guard extension privacy policy
In short: everything happens on your device and we receive nothing.
What happens to text you paste
When you paste on a supported AI chat site, the text is checked inside your browser tab and held in memory only until you choose Paste masked copy, Paste anyway or Cancel. It is never stored, logged or transmitted.
Permissions
None. The extension requests no browser permissions. Its script runs only on the AI chat sites listed in the extension description, and it does not read your history, cookies, tabs or other sites.
Third parties
None. Nothing is shared with, sold to or processed by anyone.
Changes
If this ever changes, the extension would have to ask for new permissions and this page would be updated first.
