In a world where data breaches make headlines weekly, traditional security measures are no longer enough. Zero Knowledge encryption represents a fundamental shift in how applications handle your data.

What is Zero Knowledge?

Zero Knowledge architecture means that the service provider - in this case, our servers - has zero knowledge of your actual data. Your information is encrypted on your device before it ever leaves, and only you hold the keys to decrypt it.

How Reborn Apps implements it

When you create an account on Reborn Apps:

  1. A master encryption key is generated on your device
  2. This key is encrypted using a key derived from your password (via PBKDF2 with 600,000 iterations)
  3. Only the encrypted key is sent to our server - we never see the actual encryption key
  4. All your data (tasks, notes, etc.) is encrypted with AES-256-GCM before leaving your device

Why this matters

  • Data breaches become harmless - even if someone gains access to our database, they only find encrypted gibberish
  • No insider threat - our team cannot read your data, period
  • No government backdoors - we can’t hand over what we don’t have
  • Your data, your control - encryption keys never leave your device

The trade-off

Zero Knowledge encryption comes with one important trade-off: we cannot recover your data if you lose your password. That’s why Reborn Apps provides recovery codes during registration - store them safely.

This is a feature, not a bug. It means your privacy guarantee is mathematical, not just a policy promise.
