PlainMark privacy policy
This policy covers the PlainMark Android app (“PlainMark”), which adds text and logo watermarks to your photos and videos. In short: PlainMark does not collect, sell or share any data. It has no account, no ads, no analytics and no tracking. The app does not even have permission to use the internet.
Information the app handles
- Photos and videos you pick with Android's photo picker or file picker, or share to PlainMark from another app.
- Logo images you import, your saved watermarks, the last watermark you used, optional “my details” (such as a name or website you type for quick inserts) and your settings.
- The watermarked copies PlainMark saves for you (in Pictures/PlainMark or Movies/PlainMark on your phone).
All processing (drawing the watermark, saving photos and re-encoding videos) happens on your phone. Nothing is ever sent to the developer or anyone else.
Photo metadata
Saved photo copies keep basic details of the original (such as the date and camera model). By default, the location where a photo was taken is removed from the copy; you can change this in Settings.
Permissions
PlainMark asks for no storage, camera, microphone, location or contacts permission. You choose each file in Android's own picker, which gives the app access to that file only. New files are added to your gallery through Android's media store, which does not need a permission on Android 10 and later.
Sharing
Files leave your phone only when you choose to share them, and only to the app you pick.
Storage and deletion
Your original photos and videos are never changed. Deleting a saved watermark or logo in the app removes it from the app. Uninstalling the app removes all its data (watermarked copies stay in your gallery until you delete them). Since we never receive your data, there is nothing for us to delete on our side.
What we don't do
- We don't collect personal or sensitive information.
- We don't sell or transfer user data to third parties.
- We don't show ads or use advertising IDs.
- We don't use analytics or crash-reporting services.
Children
The app is not directed at children under 13 and does not knowingly collect information from anyone.
Changes
If this policy changes, the updated version will be posted on this page with a new date.
