Who we are
Duo Doodle Sketch is published by Cryptoniar. Questions about privacy: contact@cryptoniar.com.
What the app stores on your device
- Your doodles, challenge stars, and preferences (sound, haptics, casing, paper, shake setting).
- Optional Lifetime purchase status via Apple StoreKit.
iCloud (optional, Lifetime)
If you buy Lifetime and leave iCloud Sync on, My Doodles and challenge stars sync through your personal iCloud account. We don’t operate that storage — Apple does, under your Apple ID. Casing, paper, and feel settings stay on-device.
Analytics & Crashlytics
We use Google Firebase Analytics and Crashlytics to understand stability and high-level usage (for example: mode selected, challenge finished, paywall viewed, purchase result). These services may process device and app identifiers according to Google’s privacy terms.
We don’t sell your personal information. We don’t use your doodles for advertising.
Purchases
Lifetime is processed by Apple. We never see your full payment card details. Restore Purchases uses your Apple ID entitlement.
Children
Duo Doodle is a drawing toy suitable for a broad audience. We don’t knowingly collect personal information from children for marketing.
Changes
We may update this page when the app or our tools change. The date at the top will reflect the latest revision.
