Choose how you want to sign in to Cal 3D.
Signing in happens in the app. Cal 3D accounts are real — they sync your diary between your iPhones — but there is no sign-in on the web. These are the ways it works inside the app; everything else works without an account at all.
Curious what an account holds? See the account page — it is illustrative, with example data rather than yours.
Your diary lives on your iPhone; with an account it is additionally synced to your other devices. What we store and what we do not is written down under Privacy Policy. Anything else: support@cal3d.app.
