Privacy
Privacy isn't a feature — it's the foundation
Every architectural decision in Whispurr was made with one question in mind: what's the minimum amount of data we actually need?
AES-256 Encryption
Every message and media file is encrypted with AES-256-CBC before it ever leaves your device. The server never sees your plaintext.
Key Exchange
Encryption keys are derived per-conversation and never stored on our servers. Only you and your contact can decrypt the messages.
No Metadata
We don't log who you talk to, when, or how often. Message metadata is as sensitive as the content — we treat it that way.
Zero Knowledge
We can't read your messages even if we wanted to. Our architecture is designed so that decryption is only possible on your device.
Auto-Delete Ready
Messages are stored only as long as needed for delivery. Set conversations to auto-clear and they're gone — for real.
Open to Audit
Our encryption implementation is transparent and follows industry standards. No secret sauce, no hidden backdoors.
