Privacy & Security

Your conversations live on your computer. Not on ours.

ThreadWave is local-first: messages, media, call logs and recordings are stored encrypted on your own machine. Our relay passes new messages through and forgets them.

Encrypted at rest

An encrypted local database and encrypted media files, with keys kept in your OS keychain.

No cloud copy

The relay deletes each event as soon as your app confirms it arrived — 7 days at most if you’re offline.

You hold the keys

Access tokens stay in your keychain. App lock, retention rules and one-click erase are under your control.

Why local-first?

Cloud inboxes keep a copy of every conversation on their servers. With ThreadWave there is no central archive of your customers’ messages to leak, sell or subpoena.

  • Data stays on hardware you control
  • Retention rules you set

How it works

How privacy & security works

Event arrives

Meta sends a new message or call event to the ThreadWave relay over TLS.

Pass-through

The relay verifies Meta’s signature and forwards it to your desktop straight away.

Delete

As soon as your app confirms delivery, the relay’s copy is deleted.

Encrypt

The message is written to an encrypted database on your machine. That’s the only copy we touch.

Under the hood

The details that matter

What privacy & security actually does, in specifics.

At rest

Relay retention
