Privacy notice (Public Beta)
Guest items, notes, tags, reviews and quiz drafts are stored in IndexedDB on the app origin. The public site cannot read this storage. The private tool loads no advertising or third-party analytics scripts.
Accounts and cloud sync are not currently enabled. Browsers can clear local storage; export regularly and keep private export files safe.

This notice covers the device-only Public Beta. Your items and quiz answers are not uploaded to us. Cloudflare hosts and protects the website and processes network request information, such as IP addresses, separately from your local private records. If you email us, we use your message to respond to support or privacy requests.
Use your browser’s site-data controls to delete local records. Export first: we cannot restore cleared data. Keep or delete export files yourself. We cannot read your local storage. Contact the email above for privacy or correspondence requests. Notice date: 2026-10-09.
