Overview

Kithra is an encrypted async video messaging app. It is designed so the relay server cannot read the contents of your videos.

Data we process

Kithra may process account identifiers, device identifiers, public encryption and signing keys, contact relationship metadata, message metadata, encrypted video blobs waiting for delivery, IP addresses, and basic server logs needed to operate and secure the relay.

Video content

Kithra encrypts video messages on your device before upload. The relay stores encrypted blobs only and does not receive plaintext video. Recipients decrypt videos on their own devices.

What we do not do

Kithra does not sell personal data, does not use advertising SDKs, and does not use third-party analytics or tracking SDKs.

Retention

Undelivered encrypted blobs are retained by the relay for a limited period and then expire. The current default retention window is 7 days. Message metadata may remain on the relay so the app can show conversation history, delivery status, and contact state.

Account deletion

You can request account deletion in the app from Settings. Account deletion removes the relay account, device and session records, contacts, message metadata, and pending encrypted relay blobs associated with the account. The app also clears local encrypted media and device keys from that device.

Contact

For support, use the developer contact listed in the app store where you installed Kithra.
