Your data is yours
CouShell is local-first. Your work is stored on your device first and only synced to a server you choose. We do not sell or rent your data.
No tracking by default
The CouShell app does not embed third-party advertising or behavioural tracking. This marketing site uses only what is needed to serve the page.
Sign-in
Authentication uses passkeys (Face ID, Touch ID or a security key). There are no passwords for us to store or leak.
Self-hosting
CouShell runs on the open Abracadabra engine. You can host your own server, in which case your data never touches our infrastructure.
