Privacy across our apps
Our apps are made by Kynoss Studios LLC ("we") and built to know as little about you as possible: no accounts, no ads, no third-party trackers, and we never sell your data or share it with advertisers. The table shows where each app's data goes, and each policy spells it out.
- No accounts
- None of the apps ask you to sign up. Where they sync, share or play with friends, they use Apple's iCloud and Game Center.
- No ads or trackers
- No advertising code, no third-party analytics and no cross-app tracking in any app.
- Cloud AI only where it's listed
- Apps that send anything to an AI service say so below and in their policy, including what is sent and how long it's kept.
- You know where it lives
- Each policy says what is stored where and how to delete it. Deleting an app removes its data from your iPhone; anything synced to iCloud stays under your Apple account until you remove it.
