Designed from the ground up with privacy as a core principle. Real end-to-end encryption, not marketing.
Your financial data is encrypted in your browser before being sent to the server. Not even we can read it.
You define an encryption password that only you know. It is never sent to the server.
An AES-256 key is generated using PBKDF2 with 600,000 iterations and a unique salt.
Each piece of data is encrypted with AES-256-GCM before leaving your browser. The server only stores encrypted blobs.
Military-grade symmetric encryption algorithm. The same standard used by governments and financial institutions.
Key derivation with 600,000 iterations. Makes a brute-force attack computationally infeasible.
Each encrypted block includes an authentication tag that guarantees data has not been tampered with.
If you forget your encryption password, we cannot recover your data. This is the guarantee that no one else can access it.
Even with encryption enabled, you can receive payment notifications. You decide how much information to reveal in each alert.
You only receive a notice that you have a pending charge. No amount or concept.
Notification example:
"You have a pending charge. Access the platform for more details."
You receive the charge amount but not the concept. You know how much, but not what for.
Notification example:
"You have a pending charge of €49.99. Access the platform to see the details."
You receive all the information: concept, amount and date. Maximum convenience, less privacy.
Notification example:
"Tomorrow Netflix will charge €17.99."
