DayCast

Your day, captured.

Your notes, tasks, journal and spending — read from your own iCloud and decrypted right here in the browser. Apple only ever holds ciphertext.

Why this is safe

• No DayCast server, no DayCast account. You sign in with Apple; there is nothing of yours for us to hold.
• Your data lives in your own iCloud. This page reads the same private database your devices sync through.
• Encrypted before it ever syncs. Each device seals your notes, tasks, journal and spending; Apple only stores ciphertext.
• The web passphrase wraps the key. Unwrapping happens in this browser. The key stays in memory for this tab — or, if you choose Remember, in this browser's own non-extractable key store. It is never sent anywhere.
• A static page, nothing more. Served from Cloudflare Pages with zero analytics and zero trackers. The only network calls are to iCloud.
• New captures are sealed to your phone. Anything you add here is encrypted to your phone's public key, so even the inbox relay cannot read it.
• Locks itself. After 15 minutes idle, or 5 minutes in a hidden tab, the key is dropped and you unlock again.
• Forgot the passphrase? Set a new one in DayCast → Settings → Web & Email. Nothing is lost: the app still has the key.
