Konvoro: Private Messenger
No Phone Number or Contacts
Only for iPhone

PRIVATE COMMUNICATION BY PERSONAL INVITATION
Konvoro does not scan your address book or automatically search for people you know. A secure one-to-one connection is created only when a personal invitation is sent and accepted.
END-TO-END ENCRYPTED
Text messages, voice messages and photos taken directly inside Konvoro are end-to-end encrypted. No one outside the secure connection – including the server operator or administrator – can read their contents.
CAPTURE PROTECTION
Capture protection can be enabled for newly sent text messages, photos and voice messages in direct conversations. While iOS detects active screen recording, mirroring, AirPlay or remote control, Konvoro hides protected content.
Individual screenshots are reported by iOS only after they have been taken and therefore cannot be reliably prevented. Konvoro informs the user when a screenshot has been detected.
SECURE CALLING
You can call existing Konvoro contacts directly within the app. Incoming Konvoro calls are signalled even when the app is in the background or the iPhone is locked. Individual ringtones can be selected for contacts. Call content is not stored as a recording or permanent call archive.
A COMMUNICATION CHANNEL, NOT AN ARCHIVE
Konvoro is designed for confidential communication, not for building a permanently stored chat history.
Messages that have not yet been deliberately opened remain end-to-end encrypted on the server until they are opened or their selected retention period expires. The retention period can be set per connection and is limited to a maximum of 24 hours.
After a received message has been deliberately opened and then closed, it does not remain available as permanent chat history. The conversation overview displays neither message contents nor a last-message preview.

DELIBERATELY FOCUSED
Konvoro has a clear purpose: create deliberately chosen private connections and transmit confidential communications securely while minimizing unnecessary stored data.
Each Konvoro identity belongs to exactly one device. A new device receives a new identity, and secure connections must be established again. An internet connection is required. Konvoro currently supports iPhone.
Ratings & Reviews

New: Send encrypted meeting points with an address and optional note, then choose to open the address in Apple Maps. Quick replies and time-limited group polls make coordination easier. Improvements to group readiness, message retrieval and calls, with clearer status messages.
