Why self-host

Your data, on hardware you control.

Every byte your subscribers and family generate — messages, photos, calendar, transactions, AI conversations — lives on your machine. Cloudflare Tunnel routes traffic over SSL but never sees the payload. Your encryption key. Your storage. Your call.
