Stillmode Privacy Policy

Effective date: 2026-09-02

Stillmode ("the app") is an app blocker and focus timer provided by DDJ A1 ("we", "us"). It lets you group distracting apps into "block sets", start a timed focus session, schedule sessions to repeat, and see how many times a blocked app was opened during a session. Stillmode 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 configure in the app — block set names, the list of apps you chose to block, session lengths and schedules, session history, block counts, 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 Share features, the shared text is delivered only to the destination you explicitly choose (for example a messaging app), and its safekeeping is under your control.

Permissions the app asks for and why

• Usage access (PACKAGE_USAGE_STATS). Used only while a session is running, to detect that an app on your block list has come to the foreground so the block screen can be shown, and to sort the app picker by today's usage. Usage information is read on the device and is never sent anywhere.
• Display over other apps (SYSTEM_ALERT_WINDOW). Used only to show the block screen on top of an app you chose to block during a session.
• Device admin (optional). If you turn on "Prevent uninstall" in Settings, the app registers as a device administrator solely so it cannot be uninstalled in the middle of a session. It uses no device-admin policies (it cannot wipe, lock, or change your device) and you can turn it off at any time in Settings.
• Notifications (optional). For the ongoing-session notification and optional local reminders.

The app does not use the Accessibility Service and does not read the content of other apps.

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 block sets or session history, which never leave your device.

Advertising

The app displays advertisements provided by Google AdMob. Ads are never shown on the block screen. 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

The session notification and reminders (morning plan and evening recap) are scheduled and shown locally on your device. No push notification service is used, and notification content is not sent to any server.

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.
