StudyTick Privacy Policy

Effective date: 2026-09-02

StudyTick ("the app") is a study stopwatch provided by DDJ A1 ("we", "us"). It lets you track study time by subject, review your sessions on a daily log, see weekly, monthly and yearly statistics, and start or stop a subject from a home screen widget or the notification bar. StudyTick is deliberately designed as a local-only app: it has no account system, no login, no server, and no cloud storage operated by us.

Data stored on your device

Everything you enter into the app — subject names, study sessions (start and end times), manually added or edited records, daily goal, day-start time, reminder times and app preferences — is stored only on your device and is never transmitted to us. There is no sign-up, account, or login. Deleting the app deletes all of this data from your device.

Android's standard app backup may include this data in your own Google account backup if you have device backup enabled; that backup is controlled by you and Google, not by us.

If you use the Export backup file feature, the app writes a file to the location you choose on your device or in a storage provider you select; that file is under your control. If you use the Share features, the shared text or summary image is delivered only to the destination you explicitly choose (for example a messaging app).

Information collected automatically

When you use the app, certain information may be collected automatically by third-party SDKs used for advertising. This may include:

• Your device's Internet Protocol (IP) address
• Your device's advertising identifier (Advertising ID)
• App usage events such as session time and screens viewed
• The mobile operating system and device model you use

This information is processed by the advertising provider described below and is not linked by us to your study records, which never leave your device. Advertising requests do not include your subject names or study times.

Advertising

The app displays advertisements provided by Google AdMob. To serve ads, AdMob and its partners may access your device's Advertising ID and the information described above. For users in the European Economic Area (EEA), the United Kingdom, and other regions where required, the app presents a consent form via Google's User Messaging Platform (UMP) before personalized advertising data is used; if you decline, non-personalized ads are shown instead. You can reset or limit ad personalization at any time in your device settings (Settings → Google → Ads), and you can change your consent choice from the app's Settings screen ("Ad privacy options").

For more information on how Google uses data when you use partners' apps, see https://policies.google.com/technologies/partner-sites.

Notifications and alarms

The "recording" notification, the optional morning and evening reminders, and their content are created and shown locally on your device using the Android alarm and notification systems. No push notification service is used, and reminder content is not sent to any server. Reminders are scheduled with inexact alarms and do not require any special alarm permission.

In-app review

The app may occasionally ask whether you would like to rate it using the Google Play In-App Review API. This request is handled by Google Play and is subject to Google's privacy policy; we do not receive personal information from it.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from children. The app displays ads configured through Google AdMob in accordance with Google's policies.

Your rights

Because your records exist only on your device, you are in direct control of them: you can view, edit, or delete them in the app at any time, and uninstalling the app removes them completely. Depending on your region (e.g. GDPR in the EEA/UK, CCPA in California), you may also have rights regarding data processed by advertising SDKs; you can exercise ad-related choices through the consent form and your device's ad settings described above.

Security

Your records never leave your device, which removes the most common exposure paths (server breaches, account leaks). We recommend protecting your device with a screen lock.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the app after changes constitutes acceptance of the updated policy.
