Privacy Policy

Information you provide to us

None. The App has no user accounts and does not ask you to provide personal information such as your name, email address, or payment-card details.

Information collected automatically

When you use the App, the following information may be collected automatically by us or by our third-party providers:

• A device identifier — on iOS the “Identifier for Vendor” (IDFV) and on Android the Android ID. This is used to recognise your device across app launches for analytics, crash reporting, and to restore your subscription.
• Usage and interaction data — anonymous, event-based analytics about how the App is used (for example: starting or completing a lesson or exam, exam score and pass/fail result, opening the subscription screen, changing the language or theme). These events do not contain your name or contact details.
• Crash and diagnostic data — if the App crashes or encounters an error, we receive crash logs, stack traces, and contextual diagnostic information to help us fix problems.
• Technical and device information — such as device model, operating system and version, app version, language/region settings, and similar technical data collected by our providers.
• Advertising identifier and ad data — to show ads to non-subscribers, Google AdMob may use your device's mobile advertising identifier (Apple's IDFA on iOS, Google Advertising ID on Android), your IP address, and information about your ad interactions. You can reset or limit this in your device settings (see “Advertising”).
• Approximate location (coarse) — our analytics and advertising providers may infer an approximate region (e.g. country) from your IP address. The App does not use GPS or collect precise location.
• Subscription status — whether you have an active subscription, and the associated purchase/transaction information used to manage and restore it.

Information stored only on your device

The following data is stored locally on your device (using on-device storage) and is not transmitted to us:

• Onboarding completion status;
• Language and theme preferences;
• Sound and vibration settings;
• Favorite questions and bookmarks;
• Questions answered incorrectly and their spaced-repetition review schedule;
• Mastered questions;
• Exam history (scores, dates, durations, and pass/fail results);
• Your subscription/“premium” status flag and daily free-exam counter.

You can clear this on-device data at any time by using the reset option inside the App's settings, or by uninstalling the App.

We use the information described above to:

• Provide, operate, and maintain the App and its core study and exam features;
• Provide, verify, and restore your paid subscription;
• Display advertising to users who do not have an active subscription;
• Understand how the App is used so we can improve it and fix problems;
• Detect, prevent, and address technical issues, fraud, and abuse;
• Comply with our legal obligations.

Legal bases (for EU/EEA users under the GDPR). We rely on:

• Performance of a contract — to provide and restore your subscription;
• Our legitimate interests — to operate and improve the App, perform crash diagnostics, and ensure security and prevent abuse;
• Consent — where consent is required by law, including for personalized (interest-based) advertising and the use of advertising identifiers (and, on iOS, your App Tracking Transparency choice). You may withdraw consent at any time (see “Advertising” and “Your Rights”).

We do not sell your personal data. We share limited data with the following service providers, who process it on our behalf or as independent controllers for the purposes described:

The free version of the App shows ads provided by Google AdMob. By default, these ads may be personalized (interest-based) — selected using information such as your mobile advertising identifier and your ad interactions.

When ads first appear, we ask for your consent through a consent form (provided by Google's User Messaging Platform), and on iOS through the App Tracking Transparency prompt. Your choice determines whether you see personalized or non-personalized ads, and you can change it at any time:

• On iOS — Apple requires your permission (App Tracking Transparency) before an app can access the advertising identifier (IDFA) for tracking. If you do not grant permission, you will be shown non-personalized ads. You can change your choice at any time in Settings → Privacy & Security → Tracking.
• On Android — you can opt out of ad personalization and reset or delete your Advertising ID in Settings → Google → Ads (or Settings → Privacy → Ads).

You can remove all ads entirely by purchasing a subscription.

The App offers an optional paid subscription that unlocks the full feature set and removes ads. Subscriptions are sold and billed through the App Store (Apple) or Google Play (Google), and managed through RevenueCat. We do not collect or store your payment-card information. Billing, renewals, and cancellations are handled by Apple or Google according to their terms.

Data stored locally on your device is kept until you reset it within the App or uninstall the App. Data held by our third-party providers (Firebase, AdMob, RevenueCat) is retained according to their respective retention policies. We keep analytics and crash data only for as long as necessary for the purposes described in this policy.

We rely on reputable providers (Google, RevenueCat, Apple) whose services transmit data over encrypted connections. On-device data is stored using the operating system's app storage. Because the App has no first-party servers, we do not maintain a central database of your personal data. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Our service providers (including Google and RevenueCat) may process data on servers located outside your country, including in the United States. Where data of EU/EEA users is transferred internationally, these providers rely on appropriate safeguards (such as the European Commission's Standard Contractual Clauses).

If you are located in the EU/EEA, you have the following rights under the GDPR:

• Access — to request a copy of the personal data we hold about you;
• Rectification — to have inaccurate data corrected;
• Erasure — to have your personal data deleted (“right to be forgotten”);
• Restriction — to restrict our processing of your data;
• Portability — to receive your data in a portable format;
• Objection — to object to processing based on legitimate interests;
• Withdraw consent — where processing is based on consent, at any time;
• Complaint — to lodge a complaint with a supervisory authority. In the Netherlands this is the Dutch Data Protection Authority (Autoriteit Persoonsgegevens, autoriteitpersoonsgegevens.nl).

Because the App does not collect your name or contact details, we may have only a device identifier and no way to link it to you personally; in some cases this may limit our ability to identify your data, but we will make reasonable efforts to honour valid requests.

To exercise any of these rights, contact us at support@theorygo.app. You can also limit data collection by adjusting your device's privacy and advertising settings, or by uninstalling the App.

The App is intended for users who are preparing for the Dutch driving theory exam and is not directed to children under the age of 16. We do not knowingly collect personal data from children. If you believe a child has provided data to us, please contact us at support@theorygo.app and we will take appropriate steps.

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above and, where appropriate, provide notice within the App or on the App's store listing. Your continued use of the App after an update means you accept the revised policy.

If you have any questions or requests regarding this Privacy Policy or your data, we'd like to hear from you.
