Dueberry Privacy Policy
Effective date: 2026-11-13
Dueberry ("the app") is a subscription tracker provided by DDJ B1 ("we", "us"). You add the subscriptions and recurring payments you pay for by hand, and the app shows upcoming payment dates, a payment calendar, totals per week, month and year, and reminds you before a payment or the end of a free trial. It has no account system, no login, no bank connection and no server operated by us.
Information stored on your device
The subscriptions you enter (name, amount, currency, billing period, first payment date, optional free-trial end date, color, label, payment method text and notes, reminder preference and status) and your app settings (main currency, default reminder timing, theme, notification preferences) are stored locally on your device. The app itself does not send this information to us, and we have no server to receive it. The app does not connect to your bank, card or email and does not read your transactions.
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.
Backup files you create
If you tap Save a backup file in Settings, the app writes your subscription list to a file at a location you choose with Android's file picker (for example your device storage or a cloud drive app). If you tap Restore from a backup file, the app reads the file you pick. The app only accesses the file you select and does not upload it anywhere by itself.
Sharing
If you tap Share my list, the app creates a short text (your active subscriptions and the monthly total) and passes it to the app you select through Android's share sheet. The app does not send it anywhere by itself.
Permissions
- Notifications — optional morning reminders before a payment or the end of a free trial. You can decline; the app keeps working.
- Run at startup / vibration — to deliver reminders and restore them after the phone restarts.
- Internet / network state — used by the advertising SDK described below.
Dueberry does not request location, camera, microphone, contacts, SMS, phone or file-storage access.
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.
Not financial advice
Dueberry is a personal record-keeping tool. Amounts, totals and dates are calculated from what you enter and may differ from what a service actually charges. The app does not cancel subscriptions or make payments for you; deleting or marking a subscription as cancelled in the app does not cancel it with the service.
Children
The app is not directed to children under 13, and we do not knowingly collect personal information from children.
Your rights
Your subscription list and settings exist only on your device (and in any backup file you choose to save); uninstalling the app removes the in-app data. 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.
