The app
Requests, collections, environments and history are stored locally with SwiftData. iCloud sync is opt-in and goes through your own iCloud account; Mariner operates no servers of its own and never sees your traffic.
This website
The waitlist form stores the email address you type in our Cloudflare account (KV storage) so we can notify you once Mariner is on the Mac App Store. Nothing else is collected — no IP addresses, no analytics scripts, no third-party cookies. Write to the address below to be removed at any time.
