Your progress (cases played, answers, XP, notes) is saved on the device you play on, in the app's own storage or your browser's local storage. It is not sent anywhere unless you choose to make a transfer code (below). Uninstalling the app or clearing browser data deletes it.
The game sends anonymous play events to a database we run on Supabase: which screens and cases were opened, whether an accusation was right, the type of device (phone, tablet or computer) and the app version. Each installation has a random identifier that is not linked to your name, email, account or any advertising identifier. We use this only to see where players get stuck and to improve the game. We do not sell or share it.
If you choose "Continue on another device", a copy of your progress is stored in our database under a short code for 24 hours so that another device can collect it. The code works once. The copy contains your game progress only.
The full campaign is a one-time purchase made in the app through Google Play or the Apple App Store. Those platforms handle payment and hold your payment details; we never see them. We use RevenueCat to confirm app purchases; it receives the store's purchase receipt and the installation's random identifier.
No advertising, no analytics SDKs, no tracking across apps or sites, no location, no contacts, no account or sign-in.
The game is a crime mystery and is intended for players aged 16 and over. We do not knowingly collect personal data from anyone.
Because the data we hold is anonymous we cannot match it to you. To ask for your data to be deleted, email contactus@denellapublishing.com with the subject "ProofCrawler data". If you can, include a transfer code you made or the date you played, so we can find the records. We will delete the play events and any transfer copy we hold for that installation within 30 days and confirm by email. Purchase records are kept by Google, Apple and RevenueCat under their own policies. To clear the progress saved on your device, uninstall the app or clear the browser's site data.
