Daily Mathler is a math equation guessing game for iPhone and iPad. We designed it to respect your privacy: the app does not require an account, and it does not collect, share, or sell your personal data.
Your game progress — daily puzzle results, streaks, statistics, achievements, theme choice, and settings — is stored locally on your device. If you are signed in to iCloud, a small backup of your streaks and statistics is kept in your own iCloud key-value storage so they can follow you to a new device. This data stays inside your Apple account; it is never uploaded to us.
Daily Mathler shows ads through Google AdMob (banner and interstitial ads, plus optional rewarded ads you can choose to watch for hints). Before any tracking across other companies' apps and websites for personalized advertising, the app asks your permission using Apple's App Tracking Transparency (ATT). You may allow or deny this, and change your choice anytime in your device Settings. You can also remove all ads with a one-time Remove Ads purchase.
We use Google / Firebase Analytics to understand anonymous, aggregate usage (such as which screens are used) so we can improve the app. This data is not used to identify you personally.
Remove Ads is a one-time, non-renewing purchase — not a subscription. All purchases are handled entirely by Apple through your App Store account. We never see or store your payment information. If you reinstall the app or switch devices, use Restore Purchases in the app to bring your purchase back.
Daily Mathler is suitable for general audiences and does not knowingly collect personal information from children.
