Sealwire, the messenger that keeps nothing

Field notes

Sealwire describes a page-based messaging model rather than a persistent chat history: recipients fetch one page at a time, and the relay is supposed to delete it when the sender’s window closes. The site says accounts use random identifiers instead of phone numbers or email addresses, with contacts exchanged by QR code or single-use link. Its most carefully stated limitation is that reader watermarks provide attribution, not guaranteed prevention of a photograph or recording.
