For questions about the Drift Light tools or a page correction, email hello [at] drift-light.com.
Include the page URL and a short note about what you were trying to work out. The tools are practical room guides and cannot answer personal medical questions.
Useful corrections include a calculator assumption that is unclear, a broken form result, an image that does not match the page, or a guide that needs a more cautious wording around children, shift work, travel or persistent sleep difficulty.
For page feedback, mention whether the question was about evening light, screens, sleep-cycle timing, bedroom temperature, humidity, condensation, airflow or morning light. That helps route the note to the right part of the Night Lab.
Drift Light can improve public tool wording and examples, but it cannot provide private sleep advice, inspect a bedroom remotely, or recommend treatment for a health condition.
