Macadam
Privacy
What we collect, and what we deliberately can’t see. Plain language, no dark patterns.
The waitlist
If you join the waitlist we store one thing: your email address. We use it once — to tell you when Macadam is ready — and we don’t sell or share it. Ask us to remove it any time at hello@macadam.cam.
Accounts
When you sign in (Apple, Google, or email), we store an account record: an opaque account id, the provider identities you’ve linked, and a display name. We never receive or store your provider password.
Your designs stay yours
Live collaboration is end-to-end encrypted. Documents are encrypted on your device with a key derived from the share link; our relay only ever sees ciphertext and cannot read your models. The sharing key travels in the link, never to our servers.
