Keet is a chat, voice and video application developed by Holepunch. Users exchange messages, calls and files directly between their own devices, and the vendor describes the service as peer-to-peer, with no servers involved in message exchange. The app is offered on Android and iOS in supported regions and runs on the Pear Runtime, a stack the vendor describes as open source.
Holepunch's privacy notice names Holepunch, S.A. de C.V. as the data controller, an El Salvador company. It says personal information is stored in the European Economic Area and may be processed in other countries. The vendor's FAQ states that Holepunch is backed by Tether. For a European organisation, the design limits central data exposure, but the operator is established outside the EU and the app's own licence is not stated, so governance and support arrangements need a separate assessment.
