Hi @faceapp_ai 👋

Once you applied the filters, #FaceApp is storing insecurely your modified photo in the sdcard. As a consequence any app with the READ_EXTERNAL_STORAGE permission can get your FaceApp photos without your consent and know when you took the photos.

To be fair with #FaceApp, this is a very common error in the #Android world. For example, @WhatsApp and @WeChat store the attachments on the sdcard too.
The POC to show the problem is available on @Github, have fun! github.com/fs0c131y/FaceA…
Now, you can yell!
Follow-up on the issue: Read this thread to get the technical details about this issue.

Spoiler: For now, you cannot store something securely on the sdcard on #Android.
