When to choose which

Treat this section as heuristic. Privacy properties depend on how you use the service, not just which one you pick.

• Choose Briar if mesh and tor transport; works even without internet via local bluetooth/wi-fi..
• Choose Cwtch if no accounts, no central server, no metadata aggregation point..
• Either way, re-check the entry’s last verified date — the Messaging category churns.
