Privacy Policy

Effective September 26, 2026. Lanki stores learning progress and interface state in your browser. Anonymous study does not require an account.

If you choose a Free account, Supabase processes your email or Google identity, account profile, session metadata, entitlement status, and review state for sign-in and basic sync. Local and account-data exports happen only when you request them. Browser-origin progress does not transfer automatically.

You can delete your Free account in the app after fresh email verification. Deletion removes your account and synced learning data while preserving progress on this device unless you erase it separately. Contact support for help. No advertising, billing, or paid features are active.

Hosting and technical data

Cloudflare hosts and delivers this site and processes technical request information, such as IP addresses, requested URLs, and browser information, to deliver, secure, and operate the service. This may include operational logs and aggregate traffic statistics. Lanki does not enable browser-based audience analytics. Supabase supports optional accounts and sync; Google processes sign-in information when you choose Google sign-in.

Support and your choices

If you email support, your address and message are processed to respond to your request. You can study without an account, export your progress, sign out, or request account deletion. Local progress remains until you remove it or clear browser storage. Provider security logs and backups may persist under their retention policies; account deletion does not erase every provider log or backup immediately.

Advertising status

Google ads are not currently served. If advertising is introduced, this policy and applicable consent controls will be updated before ad serving begins. Advertising can involve third parties placing or reading cookies, using web beacons, IP addresses or other identifiers. Learn how Google uses information from sites or apps that use its services.
