Privacy Policy
Effective 8 October 2026
The short version: Catarina checks code on your own computer. Your code, your chats and your browsing never leave your browser. We have no server, no account system, no analytics and no advertising.
What Catarina reads
On ChatGPT, Claude and Gemini, Catarina reads the code blocks on the page so it can check them against a list of known risk patterns. This happens entirely inside your browser. The text is not sent anywhere, and it is not saved after the page is closed.
What Catarina stores
Catarina saves two small values in your browser's local extension storage, only on your device:
- whether you have closed or opened the Catarina panel, and
- the time you last clicked the Catarina toolbar icon.
These are not shared with us or anyone else. Removing the extension deletes them.
What Catarina sends
Nothing. Catarina makes no network requests. It does not use analytics, tracking, cookies, advertising or remote code, and it does not sell or share data.
Sending feedback
The "Send feedback" link opens a draft email in your own email app, addressed to support@getcatarina.com. Nothing is sent unless you press send. The draft includes only the Catarina version, the build number and the name of the website you were on (for example, gemini.google.com). It never includes the page address, your chat or your code. Please don't add private code, passwords or keys to a message.
If you write to us, we use your message and email address only to reply to you.
Permissions
- Access to chatgpt.com, claude.ai and gemini.google.com is needed to find and check the code blocks on those pages. Catarina does not run anywhere else.
- Storage is used for the two values described above.
Children
Catarina does not collect personal information from anyone, including children.
Limits of what Catarina does
Catarina matches known patterns. A "Clear" result means no known risk pattern matched, not that the code is safe. Please review code before you run it.
Changes
If this policy changes, we will update the date at the top of this page.
