WhisprKnow what protects you
Private messages. Clear limits.
Your private messages and media are encrypted on your device before they are sent. The service that carries them does not receive the keys needed to read them. Your passphrase also protects the identity saved on your device.
Know who you are talking to
Pair with someone you trust. Compare your conversation’s safety number with them in person or through another trusted way of speaking.
A confirmed key shows that Whispr recognises that contact’s saved key. It does not prove who the person is in real life.
Protect your device
Use a strong, unique passphrase and keep your phone and browser updated. Whispr locks after a period of inactivity, but anyone with access to an unlocked session can read it.
Malware or a compromised device can defeat these protections. Stolen encryption keys can expose saved or queued messages; encryption does not undo a device compromise.
What privacy does not mean
- Service and network operators can still observe information such as IP addresses, connection times and traffic sizes. Whispr does not promise complete anonymity.
- A recipient can copy, photograph or record a message. Disappearing messages cannot prevent this or guarantee that every copy is erased.
- Card payment providers receive the details needed to process a payment. Bitcoin payments are recorded publicly. Payment privacy differs from message privacy.
- Whispr has not undergone an independent security audit. Treat it as software with limits, rather than a guarantee against every threat.
Before you restore a recovery file
Importing a recovery file replaces this device’s saved Whispr identity, conversations and media. Anything missing from the file is lost on this device. Read the confirmation carefully and save anything you need before continuing.
