Drift Light tools run in the browser. The calculators do not need accounts, uploads or personal profiles. Some plans may be saved in local browser storage so the page can remember a simple seven-night note on the same device.
Do not enter sensitive health information. The tools are designed for ordinary bedroom setup notes such as times, room feel, temperature and humidity.
Standard hosting logs may record visits in the normal way. The public tools are intended to work without a sign-in flow.
Most calculator inputs are ordinary room notes: wake time, target bedtime, screen pattern, lamp type, temperature, humidity, condensation and airflow. They are intended to describe the bedroom setup, not the person sleeping in it.
If browser storage is used for a local plan, it should stay on the same device and can be cleared by clearing site data in the browser. Drift Light does not need a login to show calculator results.
The safest way to use the site is to keep entries practical and non-sensitive. Do not enter medical history, names of children, addresses or anything you would not want stored in a normal browser note.
