Effective date: October 21, 2026
Professor Ary is a caregiver-led flashcard app for practising with children. It does not require an account and does not ask for names, email addresses, child profiles, or dates of birth.
Professor Ary does not ask for account credentials or direct personal identifiers about a child. It does not sell data or use it for advertising.
Settings, favorites, selected card sets, and session progress are stored locally on the device so the app can remember your routine. That data is not sent to the developer.
On iOS, Apple processes purchases through the App Store; on Android, Google Play processes purchases. To verify and manage Plus, RevenueCat processes a random anonymous app user ID generated by its SDK, the app platform and device type, product and purchase history, the store transaction or Google Play purchase token, and entitlement status. We do not give RevenueCat account or child data, and we do not see or store payment details. Purchases remain associated with the Apple or Google account used to buy them. The app has no accounts or cross-store purchase synchronization. Legacy v1.0 access on iOS is granted only after a verified StoreKit AppTransaction, not from local progress.
Professor Ary does not use a third-party analytics SDK. Starting with version 1.1.1, the app sends allowlisted interaction events to our first-party collector, including events from the child-facing practice experience. The collector immediately increments daily aggregate counters and does not retain raw event records. The analytics table does not store IP addresses, User-Agent strings, accounts, per-user or per-device IDs, advertising IDs, locations, dates of birth, receipts, transaction IDs, or free-form text. Event fields are limited to app version, locale, module, set, mode, access tier, practice context, surface, trigger, plan, experiment ID, variant, outcome, and error category. The counts are used only to measure and improve the app, are not linked to an individual child or caregiver, and are not used for advertising or cross-app tracking. Because the data is stored only as aggregate counts, we cannot identify or remove one person’s contribution.
The Share action in the adult area opens the operating-system share sheet only after the grown-up check. Professor Ary does not access contacts, create a personal referral code, or receive the recipient or message content. The App Store link contains one aggregate campaign label.
The core flashcard experience works offline with bundled images and audio. Network access is used only for purchases, entitlement checks, and the first-party aggregate collector described above.
Professor Ary is intended for adult caregivers and children, including children aged 5 and under. The app has no accounts or child profiles and does not ask for children’s names or dates of birth. During child-facing practice, it sends only the limited interaction events described above; these are counted in aggregate and cannot be tied to an individual child. RevenueCat’s purchase SDK is initialized only after the adult check. The app has no ads, social features, or user-generated content. External links and purchase screens are behind an adult check or the relevant store’s purchase flow.
You can remove settings, favorites, and progress from a device by clearing the app’s storage or uninstalling the app. To request deletion of the anonymous RevenueCat customer record linked to an Apple or Google Play purchase, email mosartgames@gmail.com with the store order or transaction ID from your receipt so we can locate the record. Do not send payment-card details. Deleting the RevenueCat record does not delete the store’s transaction record or cancel a subscription; manage or cancel subscriptions in the App Store or Google Play. If you keep using the app with an active purchase or restore that purchase, a new RevenueCat record may be created. Aggregated interaction counts are not linked to individuals, so we cannot identify or remove one person’s contribution.
