Questions
The app cannot see my photos.
Open Settings, Privacy & Security, Photos, and set Stampify to the access you want. Limited access only shows the photos you picked.
I printed it and the post office refused the letter.
That is expected. The image is not postage. Buy a real stamp.
How do I delete a stamp I made?
Delete it in the app and, if you saved a copy, delete that from Photos. We do not keep a copy.
How do I contact support?
Email store@aivanaapps.com with Stampify in the subject. You do not need to attach the photo.
Delete data on this iPhone
Delete the app to remove its local data. Under this policy we do not keep a copy on a server, so there is nothing else for us to erase. Deleting the app does not delete contacts in iCloud or another account, photos in your library, or a subscription billed by Apple.
