Nibbora Privacy Policy

Effective date: 2026-11-12

Nibbora ("the app") is a study timer provided by DDJ B1 ("we", "us"). Every minute you focus earns sunflower seeds that you can spend on snacks, hats and rooms for a virtual hamster. It has no account system, no login and no server operated by us.

Information stored on your device

Your study sessions (start time, length and subject), subjects, to-do items, seeds, your hamster's name, level and items, a session in progress and app settings are stored locally on your device. The app itself does not send this information to us, and we have no server to receive it.

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

Timers and notifications

A running timer is calculated from the start time saved on your device; the app does not run a background service. When a countdown ends, the app shows a local notification scheduled with Android's alarm system. Optional daily study reminders are also local notifications. No notification content is sent off your device by the app.

Sharing

If you tap Share with a friend, the app passes a short text with a store link to the app you select through Android's share sheet. The app does not send it anywhere by itself.

Permissions

• Notifications — optional session-end alerts and study reminders. You can decline; the app keeps working.
• Run at startup / vibration — to restore reminders after the phone restarts and to vibrate when a timer ends.
• Internet / network state — used by the advertising SDK described below.

Nibbora does not request location, camera, microphone, contacts, phone or file access, and it does not monitor or block other apps.

Advertising and information collected automatically

The app displays advertisements provided by Google AdMob inside the app only (never in notifications or in the widget). To serve and measure ads and to prevent fraud, the AdMob SDK may collect and share with Google information such as your device's advertising identifier and other device identifiers, approximate location derived from your IP address, app interactions (for example ad views and taps), crash logs and diagnostics. This data is shared with Google as a third party for advertising, analytics and fraud prevention purposes. For more information see https://policies.google.com/technologies/partner-sites.

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. You can change your choice from the app's Settings screen ("Ad privacy settings") and reset or limit ad personalization in your device settings.

In-app items

Seeds, snacks, hats and rooms are earned only by studying in the app. They have no monetary value and cannot be bought with real money.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from children.

Your rights

Your study data and settings exist only on your device; you can edit or delete sessions, subjects and tasks in the app at any time, and uninstalling the app removes them. Depending on your region (e.g. GDPR, CCPA), you may have rights regarding data processed by the advertising SDK; you can exercise ad-related choices through the consent form and your device's ad settings.

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.
