Privacy policy

Titleous for Safari, and the Titleous userscript · effective 28 September 2026

The short version: Titleous collects no personal data. It runs only on claude.ai, makes no network requests and stores nothing. It has no servers, no analytics, no accounts and no tracking. Nothing it reads leaves your computer.

What Titleous accesses

Titleous works only on pages at claude.ai, and it has no access to any other website. On claude.ai it reads chat names from the page itself: the names in the sidebar's list of chats, and the name on the header of the chat you're in. It uses them to set the tab's title to the chat you're in. It never reads your messages or anything else you type.

To make sure it's running in every claude.ai tab, including tabs Safari reopens at launch, the Safari extension checks which of your open tabs are on claude.ai. Safari lets it see the addresses of claude.ai tabs only.

What Titleous stores

Nothing. Titleous keeps no data on your computer or anywhere else: no history, no settings and no cookies. While a claude.ai tab is open, Titleous leaves a short note on that page saying what it last found, for troubleshooting. The note is gone when the tab closes or reloads.

Where your data goes

Nowhere. Titleous makes no network requests of any kind, and sends no information to the developer, to Anthropic or to anyone else. It contains no analytics, crash reporting or advertising code.

This website

mackeye.app doesn't count visits and sets no cookies, and these pages load nothing from other sites. The site's home page loads its typeface from Google Fonts, whose own privacy policy covers that request. The site is hosted on GitHub Pages, whose own privacy statement covers its server logs.

Third-party services

claude.ai is operated by Anthropic, PBC, and using it is subject to their terms. Titleous only reads what claude.ai already shows you, in your own browser. Titleous is not affiliated with Anthropic.

Children

Titleous is not directed at children under 13. It collects no data from anyone.

Changes

If this policy changes, the new version will be published at this address with a new effective date.
