Your data, actually yours.
Cashfulness is built to know nothing about you. Not as a political principle, but as a technical choice. Here’s how.

01
Local first
Everything lives on your device. Open the app on a plane, underground, with no signal: it works the same.
02
No login, no account
We don’t ask for email, password, phone number. There’s no account because there’s no server that knows it.
03
Zero-knowledge encryption
When you turn on backup, your data leaves encrypted with a key that lives only on your phone. Without that key, it can’t be read.
How encryption works
A two-stop journey.
