Inklume ("the app") is provided by M4Coding. This policy explains how the app handles information. Contact: m4coding@qq.com.
When you try on a design or import an image, the photo is processed entirely on your device. Body pose detection and skin segmentation run on-device using Google MediaPipe models bundled with the app, and background removal for imported images uses Google ML Kit on-device subject segmentation. Your photos and designs are never uploaded to us, and we do not operate a server that receives them. We cannot see, access or recover your photos.
ML Kit may download its on-device model through Google Play services and may send anonymous performance and usage metrics to Google to improve the service; your images are not sent. See ML Kit terms.
The app does not require an account or sign-in. Saved designs, imported images, favorites, unlocked designs and settings are stored only on your device. Deleting a design in the app removes it; uninstalling the app removes all local data. Exported images and PDF/SVG files remain where you save or share them until you delete them. Your device may include app data in operating-system backups according to your backup settings; purchase status is excluded from backups and is restored from Google Play.
The camera is used only when you open live try-on or take a photo. Live camera frames are analyzed on your device to find your arm and are never recorded, stored or uploaded; only a photo you choose to capture is kept, and only in the app. Photo access uses the Android photo picker, so the app only receives the photos you select. When you share a file or a backup, the receiving app you choose handles it under its own privacy policy.
Image enhancement (Real-ESRGAN) and depth-aware fitting (Depth Anything V2) run entirely on your device. The depth model is downloaded once through Google Play when you first turn on depth fitting. New design collections are downloaded as small design files from GitHub Pages; these requests contain no personal information beyond what any web request includes, such as your IP address.
If you start an aftercare plan, the app schedules local notifications on your device based on the tattoo date you enter. The date stays on your device and no push service is used. You can turn reminders off at any time.
The free version shows ads through Google AdMob and uses Google's User Messaging Platform for consent where required. The Google Mobile Ads SDK may collect and share IP addresses, approximate location inferred from IP, app interactions (such as launches, taps and video views), diagnostics, and device identifiers such as the advertising ID and app set ID. Google uses this information for advertising, analytics, fraud prevention and security. This data is encrypted in transit.
Where required, a consent message is shown before ads are requested. You can reopen your ad privacy choices from Profile → Ad privacy choices, and reset or delete your advertising ID in Android settings. Pro members see no ads. See Google's Privacy Policy and Google Mobile Ads data disclosures.
Optional monthly and yearly Pro subscriptions are processed by Google Play Billing. The app reads your purchase status from Google Play to unlock Pro and keeps that status in protected local storage. We never receive your payment details.
The app may download a small public configuration file (for example, ad display settings) from GitHub Pages. This request contains no personal information beyond what any web request includes, such as your IP address, which GitHub may process under its own policy.
The app is not directed to children under 13 and we do not knowingly collect personal information from children.
Because we do not hold your photos, designs or account data, there is nothing for us to export or delete on a server. For questions or requests related to data processed by Google services, use Google's controls or contact Google. For any other privacy question or request (including under GDPR or CCPA), email m4coding@qq.com.
We may update this policy. The effective date above shows the latest version. Material changes will be reflected in the app's store listing or in the app.
