Duodays Privacy Policy

Effective date: 2026-10-21

Duodays — a couple days counter that shows how long you have been together, keeps track of upcoming anniversaries such as 100 days, monthly and yearly milestones, and lets you save memories with a photo and a note ("the app") — is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Duodays has no account system and we do not operate a server for it.

Data stored on your device

The start date of your relationship, the names and photos you add for the two of you, the anniversaries you create, your memories (title, note, date and an optional photo) and your app settings are stored only on your device and are not transmitted to us. Photos you choose are copied into the app's private storage on your device. Uninstalling the app deletes 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.

Backup files and sharing

If you use Export backup, the app writes a file containing your counters, anniversaries, memories and photos to a location you pick with the Android file picker; you decide where that file goes. Import backup reads a file you pick. When you tap Share card, the app creates an image of your counter and hands it to the app you choose in the Android share sheet. The app does not upload these files or images anywhere by itself.

Permissions the app asks for and why

• Photos (system photo picker). When you add a photo for a person or a memory, Android's photo picker lets you choose individual pictures. The app only receives the photos you pick and does not request access to your whole gallery.
• Notifications (optional). For anniversary reminders (for example 7 days before, the day before and on the day) and an optional daily note with your day count. You can decline; the counter, anniversaries and memories still work.
• Alarms & reminders and run at startup. So that reminders and the home screen widget update on time, including at midnight, and are restored after your phone restarts or the time or time zone changes.
• Internet access and the advertising identifier (AD_ID). Used only by the advertising components described below. The counter, anniversaries and memories work offline.

The app does not use the camera, the microphone, your location permission or your contacts.

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, which may be used to estimate your approximate (general) location
• Device or other identifiers, such as your device's advertising identifier (Advertising ID) and app set ID
• App interactions, such as session time, screens viewed, and ad views and taps
• Crash logs and diagnostic information, such as the mobile operating system and device model you use and ad performance data

This information is collected by the advertising SDK and shared with Google (AdMob) and its advertising partners for advertising, analytics, and fraud prevention, security and compliance purposes. It is encrypted in transit. The app itself does not send your names, photos, dates or memories off your device, and we do not link the advertising data to them.

Advertising

The app displays advertisements provided by Google AdMob: a banner at the bottom of the main screens, an ad when the app starts, and full-screen ads only at natural pauses (for example after you save a memory). No ads are shown while you are editing a memory. 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.

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

Children

Duodays is not directed to children under 13. We do not knowingly collect personal information from children.

Your rights

Because your data exists only on your device, you are in direct control of it: you can edit or delete any counter, anniversary or memory at any time, and uninstalling the app removes everything the app stored. 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.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
