Privacy Policy
Shelf for Claude · Last updated September 8, 2026
Shelf for Claude is an independent browser extension and is not affiliated with, endorsed by, or connected to Anthropic. “Claude” is a trademark of Anthropic, PBC.
What Shelf for Claude stores, and where
Shelf for Claude stores the conversations you open on claude.ai—their titles, the message text you can see on the page, and any folders and bookmarks you create—in IndexedDB in your browser. Settings, prompts and a credential-free Pro entitlement status are stored in the extension's local browser storage so the Options page and claude.ai panel can share them. License keys, activation IDs and signed license tokens are kept only in the extension's private IndexedDB; they are never copied into shared storage or the claude.ai page's storage.
This data never leaves your device except for the license check described below. Shelf for Claude does not run servers that receive your conversations, and it has no analytics, telemetry, advertising or tracking of any kind.
The one network request
If you activate a Pro license, the extension sends your license key (and nothing else) to Shelf for Claude's license server, which checks the key with our payment provider (Polar) and returns a signed confirmation. No conversation content is ever sent. Free users never make this request.
Permissions
https://claude.ai/*—to read the page you are looking at and add the Shelf for Claude panel. storage—to keep your settings. downloads—to save exports you request. alarms—to refresh an optional Pro license once a day. Shelf for Claude does not read cookies, session tokens or data from any other website, and it does not automate actions on claude.ai.
Your control
Everything can be exported as JSON or deleted from the extension's options page at any time. Use Delete all before uninstalling to remove the local conversation index. Uninstalling removes the extension's private settings and license data; Chrome may retain the claude.ai-origin conversation database until claude.ai site data is cleared.
