Privacy

The website scan

When you paste text into the scan box on this website and click Scan, all of the checking happens inside your own browser. If you are not signed in, your text is not sent to any server, not stored by Attune, and disappears when you close the page.

Accounts and saved scans

You can create a free account with Google or with an email sign-in link. Accounts are run on Supabase. We store your email address, your name if Google provides it, and the scans you make while signed in: the title, the reader description, the text you scanned and its overall score. Only you can see your saved scans. Each account keeps up to 100 scans, and the oldest are removed first.

You can delete any saved scan from My scans at any time. To delete your whole account and everything in it, contact us at the link below.

Signing in stores a login token in your browser so you stay signed in. It is not used for tracking.

The Chrome extension and the Docs and Word add-ins

The extension and add-ins read the document you have open so they can score it. That reading happens on your computer or inside your own Google or Microsoft account. Your reader description and settings are saved with the document or in your browser. Attune does not run its own servers and does not collect your documents.

If you connect your Google account in the Chrome extension, Attune uses Google's Docs API only to color paragraphs and apply word swaps you click, in the document you have open.

Deep review

Deep review is optional and only runs when you click it. It sends the paragraph you chose, the paragraphs on either side, a short outline of the document and your reader description to Anthropic's API, using an API key you provide. Anthropic's own privacy policy applies to that request. Your API key is stored only in your browser or your own Google account.

Analytics and cookies

This website does not use analytics, ads or tracking cookies. GitHub, which hosts the site, and Supabase, which runs accounts, may keep standard server logs.
