Everything you need to know about NullByte
Absolutely not. Messages are encrypted on your device before transmission. We don't have your encryption keys—they're stored only in your device's secure enclave.
Your messages are safe—they're encrypted and stored only on devices. You can install NullByte on a new device and rotate your encryption keys to invalidate the old ones.
Yes! The free tier includes unlimited encrypted messaging and calls with 1GB monthly data. Paid plans offer more data and advanced features.
Unlike other apps, NullByte requires zero personal information (no phone/email), stores keys only on your device, and includes a built-in encrypted crypto wallet.
