1. Summary
- There is no account or sign-up, and the App never connects to your bank. We never ask for your name, email address, phone number or bank details.
- Your bills, income, amounts, payments, balance and notes are stored only on your device. We do not run servers that store them.
- Bill names, amounts, balances and notes are never sent to us or to any analytics or ad service.
- Balances shown in the App are estimates based only on what you enter. The App does not give financial advice and does not offer loans, credit or any financial product.
- The App works without internet. Internet is used only for ads, usage statistics and purchases.
- The App is free and shows ads provided by Google AdMob. The optional one-time purchase Duewell Pro removes ads and adds extra features.
- To improve the App we collect usage statistics with Google Analytics for Firebase.
- The App is not directed to children under 13.
2. Data stored on your device
The App saves the following on your device so that it can work:
- the bills, income, card due dates and planned spending you add: names, amounts, dates, how they repeat, categories, notes and reminder settings;
- what you marked as paid, skipped or moved, and the payments you recorded;
- the balance you entered ("money you have now"), if you choose to enter one;
- your settings: currency, first day of the week, theme, text size, language, reminder defaults, accounts and categories;
- whether you own Duewell Pro, and simple app counters (for example how many times you marked a bill paid, used to space out ads and the rating prompt).
All data is deleted when you uninstall the App or clear its data. If Android backup is turned on for your device, Android may include this data in your Google account backup; that backup is managed by Google.
3. Permissions and how they are used
- Notifications: asked when you first save a bill with a reminder (or when you tap the reminder notice). Reminders are scheduled on your device; their content (bill name and amount) is created on your device and is not sent anywhere. You can turn notifications off in your phone's settings at any time.
- Run at startup: after your phone restarts, the time zone changes or the App is updated, the App reschedules your reminders on the device.
- Vibration: for button feedback (can be turned off in Settings).
- Internet and network state: needed for ads, usage statistics and purchases. The calendar, balances and reminders work without internet.
- Advertising ID (AD_ID): used by Google's ad and analytics services described below. You can reset or delete it in your device settings (Settings > Privacy > Ads).
The App does not use the camera or microphone and does not access your contacts, photos, files, location or bank accounts.
4. Widgets, reports and backups
- Home screen widgets (Pro): show the amount left until payday and this week's bills. Anyone who can see your home screen can see them.
- Monthly report (Pro): creates a PDF or spreadsheet (CSV) on your device. It goes only to the app or person you choose in the share window.
- Backup and restore: "Back up" writes one file with your data and settings to the location you pick. The App does not send it anywhere else.
5. Advertising (Google AdMob)
If you do not own Duewell Pro, the App shows a banner ad on the Calendar and Upcoming screens and an occasional full-screen (interstitial) ad after you mark a bill as paid. You can also choose to watch a rewarded ad to try the widgets for 24 hours or to get one monthly report. To show and measure ads and to prevent fraud, Google may collect information from your device such as the advertising ID, IP address (which can be used to estimate your approximate location), device and app information, and how you interact with ads. Ads may be personalized only where the law allows it and, where required, only with your consent. Ads are never shown while you are adding or editing a bill, and the data you enter is never shared with advertisers.
If you are in the European Economic Area, the United Kingdom or Switzerland, the App shows Google's consent form before requesting ads. Where US state privacy laws apply, the App can show Google's US privacy message, where you can opt out of the sale or sharing of personal information for personalized ads. You can change your choices at any time in Settings > About > Ad privacy options.

6. Usage statistics (Google Analytics for Firebase)
We use Google Analytics for Firebase to understand how the App is used and to improve it. It records events such as: the App was opened, setup was finished, a bill or income was added or edited (only its type and repeat pattern), something was marked as paid, skipped or moved, the balance was updated (without the amount), a reminder was set or shown, a setting such as theme, text size or language was changed, a widget was added, a report or backup was made, the Pro screen was opened, a purchase was completed or restored, and whether an ad was shown. Bill names, amounts, balances, dates and notes are never included.
Firebase also collects some information automatically, such as an app instance ID, device model, operating system and app version, country or region, and session information. This data is processed by Google and kept for a limited period according to Google Analytics retention settings. Where consent is required, analytics storage follows your choice in the consent form.
More information: Privacy and security in Firebase.
7. Purchases (Duewell Pro)
Duewell Pro is a one-time purchase (no subscription) made through Google Play. Payment is handled entirely by Google; we never see your card or payment details. The App only receives a confirmation from Google Play that you own Pro, so it can unlock the Pro features and restore them on a new phone. Pro can also be unlocked with a code in Settings > About > Redeem code. The code is checked on your device and is not sent anywhere.
8. Ratings
The App may show Google Play's own rating window. Your rating and review are sent to Google Play, not to us.
9. Sharing and selling of data
We do not sell your data. We do not share it with anyone except through the Google services described above (AdMob, Firebase, Google Play), which act under their own privacy policies. The financial details you enter stay on your device.
10. Security
Data on your device stays inside the App's private storage, which other apps cannot read. Data sent to Google services is sent over encrypted connections.
11. Your choices and rights
- Change your ad consent or US privacy choices in Settings > About > Ad privacy options (where available).
- Reset or delete your advertising ID in your device settings.
- Turn notifications on or off in your phone's settings at any time.
- Clear the App's data or uninstall the App to remove all data from your device.
- Depending on where you live (for example under the GDPR, US state privacy laws such as the CCPA/CPRA, or Türkiye's KVKK), you may have the right to access, correct or delete personal data, to object to its processing, and to opt out of its sale or sharing. Because we do not keep your data on our own servers, most requests concern data held by Google; contact us and we will help.
12. Children
The App is not directed to children under 13. We do not knowingly collect personal information from children.
13. Changes to this policy
We may update this policy when the App changes. The "Last updated" date at the top shows the latest version.
