737 Systems Study — Privacy Policy

Effective: 28 September 2026. This policy covers the iOS app net.mydrivingtest.type737prep. For privacy questions, email dttquestionreport@gmail.com and name the app.

Study data on your device

The app stores your onboarding choice, saved and missed question IDs, and up to 50 recent session summaries (date, topic or mode, correct answers, and question count) in iOS UserDefaults. The current question session is held in memory. Saved and missed IDs and dated history records are not sent in analytics events; answer correctness and score/count values may be sent as described below. Deleting the app and its data removes these local records; Apple controls any iOS device backups.

Analytics and app data

When the production Firebase configuration is bundled, Google Analytics for Firebase receives events for app opening, onboarding completion, practice start, answer correctness, session completion and score counts, paywall views, purchase start and completion, restore outcome, recognized deep-link route, and content-load errors. App-defined event details include a product ID and simple mode, count, route, or outcome values. The app does not put question wording, answer choices, your name, email address, or payment-card details into these events.

For version 1.0, the app's App Store privacy disclosure covers these data categories: coarse location, device ID, purchase history, product interaction, performance data, and other diagnostic data. These data are linked to you for analytics and app functionality as described above. Firebase may collect an app-instance identifier, device or app information, usage data, and technical diagnostics under its own SDK behavior. The app does not use these data for tracking, does not request App Tracking Transparency permission, and denies ad storage, ad user data, and ad personalization in its Firebase settings.

Purchases

Lifetime access is a one-time, non-renewing App Store purchase handled by Apple StoreKit. The app checks Apple-verified transactions to unlock or restore access. It sends the StoreKit product ID and purchase or restore outcome as analytics event details when Firebase is configured. Apple handles payment information; the app does not receive your card details. This app does not offer a subscription.

Retention and support requests

Local study records remain until the app is removed or its data is otherwise erased on the device. Removing the app does not by itself erase events already sent to Google; Firebase retention and deletion controls apply to those analytics records. If you email support, we receive your email address and whatever issue details you choose to send, use them to reply, and keep them separate from automatic app analytics. Do not send passwords or card details.

Changes to this policy will appear here with a new review date. For app help, see 737 Systems Study support.
