Privacy Policy

Effective 12 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.

Catarina also checks the message you are about to send on these sites, to warn you if it contains an API key, token or password. This check also happens entirely inside your browser. Your message is not stored by Catarina and is not sent anywhere by Catarina.

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.

Emails you send us

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. We keep your emails only as long as needed to help you, and delete them on request. To ask, write to support@getcatarina.com.

Permissions

• Access to chatgpt.com, chat.openai.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 itself does not collect personal information from anyone, including children.

Changes

If this policy changes, we will update the date at the top of this page.
