Your data, for your eyes only
Security at the architecture level — not just marketing, but technical implementation.
End-to-End Encryption (E2EE)
Optionally enable E2EE mode. Keys stay local — the server cannot decrypt any ledger data. Even if the server is compromised, your data remains ciphertext.
Transport Encryption
All API communication is encrypted in transit — no eavesdropping on your ledger data.
Password Security
Passwords stored with Salted SHA-256 hashing. No one (including admins) can retrieve your plaintext password. Email-based reset supported.
No Tracking · No Ads
We don't sell data, don't run ads, don't use third-party trackers. Your spending records belong to you alone.
Security features depend on correct usage. E2EE is implemented client-side — please verify independently. See full disclaimer for details.
How Your Data Stays Private
From your device to the server, every step is protected —
Dual-layer protection: E2EE encrypts content + TLS encrypts the channel. Even if any node on the path is compromised, your data remains garbled ciphertext.

Not just marketing — honest comparison with traditional approaches.
