Any data you input on the app, such as scans, classes and student names, as well as computed data such as scores, statistics and reports do not leave your device unless you explicitly share it from within the app. Rejected scans (for example errors, blurry, or false positive scans) might be automatically collected in order to improve the app.
In-app payment for subscriptions are processed by Google's Google Play or Apple's App Store.
The app will never show ADs.
We may use analytics software (such as Google Analytics) to analyse user behavior on the website and the app.
If there is a privacy breach, I will disclose it immediately on the twitter account.
