Privacy Policy

Local by design: Quick Math requires no account and contains no advertising, analytics, tracking, telemetry, cloud sync, generative AI service, or Studio AM data server. Profiles and practice records are stored locally. Apple handles App Store transactions, and an export leaves the app only when you choose a destination in the system share sheet.

1. Information we collect

1.1 Personal information

Studio AM collects no personal information through Quick Math. The app has no Studio AM account, email login, or remote user identifier. Names, emoji avatars, profile modes, and settings you enter are stored in the app's local record and are not sent to us.

1.2 Practice record

Quick Math stores profiles, scores, stages, streaks, goals, achievements, times-table progress, per-operation statistics, Family Board totals, and problem results locally in the app's durable record. Detailed problem history retains the newest 2,000 stored answers. A last-known-good local copy helps recover the current record if the primary file becomes unreadable.

1.3 Widget snapshot

If the streak widget is installed, Quick Math writes a small local snapshot to its Apple App Group so the widget can show the current streak and daily-goal progress. The snapshot is available only to the Quick Math app and its widget; it is not sent to Studio AM.

1.4 Analytics and advertising

Quick Math contains no third-party analytics SDK, advertising SDK, cross-app tracking, or Studio AM telemetry. We do not receive practice events or profile data.

2. On-device features

Problem generation, scoring, adaptive selection, strategy matching, times-table analysis, weak-spot analysis, and the weekly parent note run locally. The weekly note uses deterministic templates built from recent practice facts. It does not use Apple Intelligence, a generative model, or an online AI service.

3. Network use and external destinations

Practice works offline after access has been verified. Apple's StoreKit may connect to the App Store to load plans, complete a purchase, restore an earlier purchase, or update entitlement status. If you choose email support, Manage Subscription, Terms, Privacy, or another Studio AM app, iOS opens the corresponding external service or page. Studio AM does not transmit those links in the background.

4. Subscriptions and earlier lifetime purchases

Quick Math offers monthly and annual auto-renewable subscriptions through Apple. Eligible new subscribers may receive a 3-day trial; Apple determines eligibility and displays the price, renewal terms, and local currency before confirmation. A retired lifetime product is no longer sold, but verified earlier owners can retain access through Restore Purchases. Studio AM does not receive your payment-card details.

5. Your access, export, and deletion controls

The data door remains available without an active subscription. From the plans screen or Settings, you can inspect the complete current local record, prepare a complete lossless JSON file plus a readable plain-text summary, or delete the record. The system share sheet sends prepared files only to the destination you choose. Quick Math clears older managed temporary export files before preparing a replacement and when you delete the record. Deleting local data does not cancel an Apple subscription.

6. Notifications

If you enable practice reminders, Quick Math schedules them locally through iOS. Studio AM runs no push-notification server and does not receive your reminder settings. Paid reminders are scoped to verified access and are canceled or not scheduled beyond subscription expiry.

7. Children's privacy

Quick Math includes a Kid profile, but it collects no personal information from children or adults. There are no accounts, ads, analytics, tracking, or remote practice profiles. Families should choose where to send an export before using the system share sheet.

8. Changes to this policy

If Quick Math's data practices change, this page will be updated and its effective date revised before the change ships.
