- Do I need to create an account?
- No — your card is anonymous until you choose to sign in. The first stamp creates it automatically.
- Will it use a lot of storage?
- Less than 1 MB. It's a web app wrapped in your home screen, not a heavy native install.
- Can I uninstall it?
- Yes — long-press the icon and remove, like any app. Your stamps stay safe in our backend.
