One Lie (“the app”, “we”, “us”) is a logic-puzzle game published by Dalu. This policy explains what data the app handles. The short version: we don't collect any.
None. One Lie has no accounts, no sign-in, no advertising, and no analytics or tracking tools. We do not collect your name, email address, location, contacts, photos, device identifiers, or any other personal information.
The following is saved only on your device, so you can pick up where you left off: your puzzle progress (which cases you've opened, solved or revealed, how many hints you used, and your current selections), the detective you chose and the optional name you gave it, your language and sound settings, the day you started playing (used to open one new case a day), and whether you have unlocked all cases. On the website version it is kept in your browser's local storage. This data never leaves your device, and we cannot see it.
Deleting the app, or clearing your browser's site data, removes it permanently. A purchase is not lost this way: you can get it back with “Restore purchases”.
One Lie offers one optional in-app purchase, “Unlock All Cases”. It is handled entirely by Apple through the App Store. We never see your payment details, your Apple ID or your name; the app only learns from Apple whether the purchase has been made. Apple's own privacy policy applies to the payment.
To deliver new cases and fixes without a full app update, the app asks Expo's update service (expo.dev) whether a newer version of the game content is available. Like any request on the internet, this includes your IP address and basic technical details such as the app version and platform, which Expo uses only to deliver the update. We do not receive or store this information.
If you tap “Share result”, your device's own share sheet opens with a short message such as “Solved first try, no hints.” Nothing is sent unless you choose where to share it, and the message never contains the answer. We do not sell or share any data with third parties.
One Lie contains no violent or mature content and collects no personal information from anyone, including children.
If a future version of the app adds features that handle data, such as optional usage statistics or in-app purchases, we will update this policy before that version is released and change the date above.
