๐Ÿ”’ Hardware-Backed Zero-Knowledge Privacy

The personal vault your budget deserves.

Keepr is a secure, collaborative personal finance tool designed for couples and families. Because your budget details are your business, your data is encrypted directly on your device. We store only unreadable codeโ€”meaning even our backend server cannot see your transaction logs.
