Privacy Policy

Last updated: June 2026

Lifle is a daily nature guessing game playable at lifle.app, as a Trusted Web Activity on Android, and as a native iOS app. No account is required to play. If you choose to create one, it lets you sync your progress across devices and access Pro features. We collect as little as possible either way.

What we collect

• Game state, on your device by default. Your guesses, streak, and stats live in your browser’s local storage. We do not see them and they never leave your device unless you create an account.
• Game state on our servers, if you sign in. When you create an account, your game history, streak, and progress are stored server-side so they sync across your devices. We store this data associated with your email address. You can delete your account and all associated data at any time at lifle.app/delete-data.
• Email address, if you sign in or opt in to reminders. We use a magic-link system for accounts: no password is ever created or stored. Your email is used to send you a sign-in link and, if you are signed in, to identify your account. If you separately opt in to daily email reminders, your address is also used for that. We do not share your email with anyone, ever.
• Payment information, for Pro subscribers. Pro subscriptions are processed by Stripe. We do not store your card number or payment details. Stripe provides us with a subscription status linked to your account email.
• Anonymous product analytics. We use PostHog and Google Analytics to understand which features people use. These tools log basic events (page views, guesses, win/loss) tied to a randomly generated anonymous ID, plus standard web details like browser, rough geographic region, and referrer. We do not collect names or precise location.
• Push notification subscriptions, only if you opt in. If you enable daily puzzle reminders via push, your browser issues an anonymous push subscription token (provided by Apple, Google, or Mozilla’s push services). We store this token to send the daily notification, and nothing else. Revoke it any time in your browser or app settings.
• Daily reminders on iOS are local only. If you enable the “Daily reminder” toggle in the iOS app, the notification is scheduled entirely on your device using iOS’s local notification system. No token or device identifier is sent to our servers.

What we don’t collect

• No passwords. Accounts use magic links only.
• No real names or phone numbers.
• No precise location (we don’t use GPS or device location APIs).
• No advertising identifiers; we don’t serve ads.
• No data is sold to anyone, ever.

Where data is stored

Game state for signed-in users, accounts, and push tokens are stored on Cloudflare infrastructure. Payment subscription status is managed by Stripe. Anonymous analytics are stored by PostHog and Google under their respective privacy policies. If you are not signed in, your game data stays on your device only.

Your controls

• Delete your account and all data at lifle.app/delete-data. This permanently removes your email, game history, and streak from our servers.
• Clear local game state by clearing site data for lifle.app in your browser, or uninstalling the app.
• Disable push notifications by revoking notification permission in your browser or system settings.
• Block analytics with most ad/tracking blockers, or with browser-level Do Not Track / Global Privacy Control signals (which we honor on a best-effort basis).

Children

Lifle is suitable for general audiences and does not knowingly target children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has created an account, contact us and we will delete it promptly.

Changes

If we change what we collect, we’ll update this page and bump the date at the top. Material changes will be reflected here before they take effect.
