MathCam (the “App”) is a math problem solver, published by an independent developer (the “Developer”, “we”, “us”). Contact: apps.contact.supports@gmail.com.
This policy explains, in plain language, what data the App handles and why.
| Category | What it is | Why | Where it lives |
|---|---|---|---|
| Camera / Photos | The photo of a math problem you capture or pick. | To read the problem and produce a step-by-step solution. | Sent to the Google Gemini API for analysis and then discarded. We do not keep a copy. |
| App preferences | Your settings and recent solutions. | To restore your experience between sessions. | On your device only. |
| Purchase records | A receipt confirming your subscription. | To unlock the features you paid for. | Validated by Google Play. We store only a yes/no flag on your device. |
| Advertising identifier | Your device's advertising ID, unless you subscribed or opted out at the OS level. | So our ad partner (Google AdMob) can show ads. | Sent to Google AdMob. We do not store it. |
We do not collect: your name, email address, phone number, contacts, SMS messages, calendar, location, or microphone audio. The App has no sign-up or login.
The App may show banner, interstitial, or rewarded ads via Google AdMob. Ads are personalised only where you allow it. In the European Economic Area, the UK, and Switzerland we show a consent prompt before serving personalised ads. You can disable ad personalisation in your device settings (Android: Settings → Google → Ads) or remove ads by subscribing.
The App is intended for a general audience including students. It is not directed at children under 13, and we do not knowingly collect personal data from them.
Photos are sent to the Gemini API to produce a solution and are not retained by us afterwards. Your settings and recent solutions live on your device and are removed when you uninstall the App or clear its data. For any request, email apps.contact.supports@gmail.com; we action verified requests within 30 days.
If you are in the EU/UK (GDPR) or California (CCPA/CPRA), you have the right to access, delete, and object to processing of your data, and to withdraw consent. We do not sell personal information.
Network requests use HTTPS. Purchases are validated by Google Play directly — we never see your payment method.
If we materially change this policy we will update the date above and, where appropriate, notify you in the App.
