Frequently Asked Questions
How do I create a stamp?
Open the app and tap the Stamp tab (camera icon) in the center of the bottom bar. Frame your photo within the stamp overlay and tap the shutter button. Your photo is automatically cropped into a postage stamp shape.
How do I send a letter?
Tap the compose button (✉️) on the Mailbox screen. Follow the 5 steps: choose a stamp, pick an envelope, select paper, write your message, and review before sending. You'll need to select a contact as the recipient.
How do I add friends?
Go to the Contacts tab and switch to the "Find" tab. Search for your friend's @handle username and send them a friend request. Once they accept, you can send letters to each other.
Where is my stamp location from?
When you take a stamp photo, the app captures your GPS coordinates and converts them to a city and country name. This location appears on your stamp and on postmarks when you use the stamp in a letter.
How do I change my profile picture?
Go to the Profile tab and tap your avatar (or the camera icon on it). Select a photo from your library. The image will be resized and uploaded as your new profile picture.
Can I change my password?
Yes, if you registered with email and password. Go to Profile → scroll down to "Change Password", enter your current password and a new one (minimum 6 characters). If you signed in with Apple or Google, password changes are managed through those services.
How do I delete my account?
You can delete your account from the Profile screen in the app (scroll to the bottom and tap "Delete Account"). You can also request deletion from our account deletion page. This permanently removes all your data.
My camera shows a black screen
Make sure you've granted camera permissions to Stamp Letter in your device settings. If the issue persists, try closing and reopening the app. On some devices, switching away from the camera tab and back can also help.
