Privacy

Short version: Tattle keeps what it records in your browser, and this site sets no cookies and loads nothing from other companies.

What the extension records

For each tab, Tattle records the cookies a site sets, what it writes to local and session storage, the databases and caches it opens, the domains it contacts, your cookie banner choice, and signs of fingerprinting. That record lives in your browser's extension storage. It is cleared when you close the tab, except a short memory per site (your banner choice and which tracking companies it used) that you can wipe in Settings.

Your email, phone and name

If you add them to the leak detector, they are stored only in this browser (not synced to your Google account). Tattle compares them, in plain and hashed form, against requests your browser sends to other companies. They are never sent anywhere by Tattle and never given to the AI.

The AI explanations

Explanations are optional. When you ask for one, Tattle sends the names of cookies and storage items, the domains involved, which company is known to use them, and a description of the value's shape (for example "a random ID" or "a date"). It never sends the values themselves, your browsing history or your personal details. They go to the AI you pick in Settings: Chrome's built-in on-device model, an Ollama server you run, or a provider you hold a key for. Tattle has no server of its own in that path.

Cleaning

When you delete cookies or clear a site, Tattle uses Chrome's own APIs on your computer. Deleted cookies can be restored for a short while with Undo; cleared storage and databases cannot.

This website

tattle.anri.ai sets no cookies, uses no analytics and loads no fonts, scripts or images from other companies. The page checks itself at the bottom with the same rules Tattle uses. Like any web server, ours keeps basic request logs (IP address, time, page requested) to stay up and secure, and they are not used for anything else. The email box on the home page computes a hash in your browser and sends nothing.

Permissions the extension asks for

• Read and change data on all websites, cookies, web requests: to see what each site stores and sends, and to delete it when you ask.
• Storage: to keep your settings and the per-tab record in your browser.
• Browsing data: for "Clear this site's data" and auto-clean.
• Side panel, tabs, scripting: to show the panel for the tab you are on and read a page's own storage.
• Declarative net request: only to remove the Origin header from Tattle's own calls to a local Ollama server, which otherwise refuses them.
