Privacy Policy

Developer: Ydeer · App identifier: com.ydeer.app.sketchmusic

This policy covers Sketch Music for iOS. Earlier releases without advertising, purchases or Firebase do not collect app data through those services. The sections below also describe monetization-enabled builds, including testing and upcoming releases. Features and third-party processing depend on the build you use and your choices. This policy does not cover the separate Android app.

Your artwork is processed on your device. We do not upload your drawings, generated music or photo backgrounds to our servers. Advertising and service providers may process the technical data described below; local creation does not mean that every app service operates offline.

1. Drawings, photos and exports

Drawings, drafts, background photos, preferences and coin balances are stored locally. Music synthesis and MP4, WAV and MIDI generation happen on your device. Camera access is optional and requested when you choose to take a background photo. You can instead select a photo with the system photo picker, or use a color background.

Sharing or saving an exported file sends it only to the destination you select through iOS. That destination may have its own privacy policy.

2. Advertising and tracking choices

Monetization-enabled builds include Google AdMob and Google's User Messaging Platform for advertising and privacy choices. Where configured, ads may include native cards, interstitials after eligible editing sessions and optional rewarded videos. The advertising SDK may process IP addresses (including approximate location derived from them), device or app identifiers, ad interactions, and diagnostic or performance information for ad delivery, measurement, analytics, security and fraud prevention.

Before starting the advertising SDK, the app completes the applicable consent flow and waits for an App Tracking Transparency decision. With your permission, the advertising provider can use your advertising identifier to personalize or measure ads across other companies' apps and websites. If permission is denied or restricted, the advertising SDK does not receive the IDFA through ATT. Denying permission does not disable free drawing or playback; ads that do not require that permission may still be available.

Manage tracking in iOS Settings → Privacy & Security → Tracking. The system may suppress the request when requests are disabled or restricted. Where required by Google's consent service, the app's Settings includes advertising privacy options. An optional lifetime purchase removes app ads. See Google's Privacy Policy and Google Mobile Ads data disclosures.

3. Optional usage and crash reports

In builds with Firebase, Analytics and Crashlytics collection is off by default. You may enable or disable “Share usage & crash reports” in the app's Settings. When enabled, reports may include app-instance identifiers, device/app information, feature usage, ad interactions and revenue events, purchase-result events, errors, crash traces and performance diagnostics. App events do not include your drawing contents, audio, photos, custom project names or file paths.

The app keeps Firebase Analytics advertising storage, advertising user-data and ad-personalization consent denied independently of this diagnostics toggle. Advertising consent is handled separately as described above. Turning off reports stops future Analytics and Crashlytics collection; it does not itself delete reports previously received by the provider.

4. Remote configuration

Configured builds use Firebase Remote Config to fetch settings such as feature availability, coin costs and ad frequency. This service can contact Firebase even when optional usage and crash reporting is off. Firebase may process an installation identifier, app/device information and technical request information to deliver configuration. Disabling optional reports does not disable Remote Config. See Firebase privacy information.

5. Purchases

Where available, a one-time lifetime purchase is processed by Apple's App Store. StoreKit supplies verified transaction and entitlement information so the app can unlock premium features and restore purchases. We do not receive your payment card details. There is no app account or subscription. Availability and the payable price are shown by the App Store.

6. Retention and deletion

You can manage local creations in the app. Deleting the app removes its local storage; exported copies, device backups and App Store purchase records are managed separately in their respective services. Provider-side technical, advertising and optional diagnostic data follows the providers' retention practices. For privacy requests, contact us below. We do not have an app account database that links your email address to your local artwork.

7. Children

The app has no public feed or user-to-user messaging and is not designated as a Made for Kids app. Tracking requests can be restricted by Apple account or device settings. Monetization-enabled builds may use the third-party services described above; this policy does not claim that those builds collect no data from any age group.

8. Support and this website

If you contact us, we receive your email address, message and any attachments you choose to send, and use them to respond. Please do not send passwords or sensitive personal information.

This website is hosted by Vercel, which may process technical request information, including IP addresses, to deliver and protect the site under its Privacy Policy. We add no analytics scripts, advertising scripts or tracking cookies to this website.

9. Updates and contact

We will update this policy when app practices change. For support or privacy questions, email ndhuynh13@gmail.com.
