MarkTint Studio

MarkTint Studio helps you add text watermarks, pick exact RGB and HEX colors, and keep reusable local edit history. The app includes an Image Watermark workspace, Color Picker controls, preset palettes, and Saved History for watermark exports and saved colors. Image selection and editing are handled locally on your device. The reviewed build does not request INTERNET, READ_MEDIA_IMAGES, READ_MEDIA_VIDEO, camera, location, microphone, contacts, notifications, or broad storage permissions. Selected images, watermark text, color values, exports, and history remain on device unless you delete them, clear app data, or uninstall the app.
