Sleep Calculator Rem is designed to operate primarily inside your web browser. We do not require account registration, and we do not collect personal identifiers like your name, email address (unless you submit it via our contact form), or IP address.
Local Storage & Cookies
Our calculators and sleep debt trackers store your configuration inputs (like bedtime preference, sleep logs, and calculated metrics) locally on your device using browser LocalStorage. This data is never transmitted to our servers.
Analytics & Metadata
We may use privacy-respecting analytics tools to collect anonymous usage metadata (such as page views, device types, and language settings) to improve user experience. No personal data is tracked or sold.

If you contact us via the contact form, the details you provide (name, email address, message) are only used to address your inquiries and are never shared with third parties or used for marketing.
