Privacy Policy

1. Privacy by Architecture

Sleep, nap and caffeine calculations run in your browser. Diary entries are stored in this site’s local browser storage.

2. Data Collection & Local Storage

You do not need an account, name, email address or phone number to use the calculations and diary. We do not request biometric data. The external services described below may receive connection information.

You can export a JSON backup and delete individual entries using Delete. To remove all entries and preferences, clear this site’s data in your browser settings. Removal cannot be undone without a backup.

3. Cookies & Third Parties

The main page loads Google Fonts and a Google AdSense advertising script. These services may receive connection information, such as your IP address and browser details, and use cookies depending on their settings and policies. Local calculations and diary storage do not eliminate these external connections. See Google’s privacy policy and your browser controls.
