Doodletune Privacy Policy

Effective date: 2026-10-21

Doodletune — a music app that turns lines you draw on a canvas into melodies, with six free instruments, saved songs you can export as audio (WAV) or MIDI files, and a new "Today's doodle" theme every day ("the app") — is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Doodletune has no account system and we do not operate a server for it.

Data stored on your device

Your drawings, the songs you save (their names, tempo, scale and key) and your app settings are stored only on your device and are not transmitted to us. All sounds are generated on your device; the app does not record audio. 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.

Files you export or share

When you choose Save as WAV, the app writes an audio file to your device's Music/Doodletune folder. When you choose Share audio or Share MIDI, the app creates a temporary file and hands it to the app you pick in Android's share sheet (for example a messenger). What happens to the file after that is governed by the app you shared it with. The app does not upload your songs anywhere by itself.

Permissions the app asks for and why

• Notifications (optional). For a morning note with Today's doodle theme and an evening reminder. You can decline; the rest of the app keeps working.
• Run at startup. So the daily notes are restored after your phone restarts.
• Vibration. For notifications. You can turn it off in the app's Settings.
• Internet access and the advertising identifier (AD_ID). Used only by the advertising components described below. Drawing, playing and exporting songs 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 drawings or songs 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 screens, an ad when the app starts, and full-screen ads only at natural pauses (after you finish saving a song and return to the home screen, and when you open a starting shape). 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

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

Your rights

Because your songs exist only on your device, you are in direct control of them: you can delete any song in the app 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.
