🔒 100% Private — How It Works
1️⃣
No server, no account. Your sleep log lives in your browser's localStorage. The digest is generated on your device, not sent by any server.
2️⃣
mailto: delivery. Clicking Send Now opens your default email app (Gmail, Outlook, Apple Mail) with the report pre-filled. You send it to yourself with one tap.
3️⃣
Monday reminder. Enable the reminder and your browser notifies you every Monday morning to open the page and send your digest.
💡
Your email address is never stored on any server. It stays in your browser localStorage only, and is only used to pre-fill the mailto: link.
