Briefleaf Privacy Policy
Briefleaf keeps your documents and snippets in your own browser. Accounts are optional, and we have no analytics and no ads. Data leaves your browser only when you use an AI feature or sign in.
Data stored on your device
The text and images you save, their source page titles and URLs, your documents and settings are stored in Chrome’s local extension storage on your computer. We cannot see them. Removing the extension deletes them.
Data sent to our server
- AI features (only when you press an AI button). The text of the snippets in that document, its title and image captions are sent to our API (hosted on Cloudflare) and passed to Anthropic’s Claude API to produce the result. Images themselves are not sent. The result is cached on our server for up to 30 days, keyed by a hash of the request, so that repeating the same request is instant and free. Anthropic processes API data under its commercial terms and does not use it to train models.
- Usage counter. A random installation ID generated by the extension is used to count AI runs for the monthly or daily limit. It is not linked to your name, email or browsing.
- Sign-in with Google (optional). If you sign in, we receive your Google account ID and email address (no access to Gmail, Drive or contacts). We store them with your Pro subscription status and the link to manage your subscription, so Pro works on all your devices. Signing out removes the session; to delete the account data, write to us.
Payments
Purchases happen on Lemon Squeezy’s checkout page, which is the merchant of record. Briefleaf never sees your card details. Lemon Squeezy notifies our server about the subscription status (active, renewed, cancelled) and the email used at checkout. See Lemon Squeezy’s privacy policy.
Website access
Briefleaf reads a page only when you add a selection or an image. The optional access to all sites, if you grant it, is used only to scroll to and highlight a saved passage when you open its source.
What we do not do
We do not sell or share your data, do not track your browsing, and do not use your data for advertising or credit decisions. Briefleaf complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
