You can use the calculators without creating an account or payment. The contact form asks only for the details needed to reply to your message.
Some preferences, such as a recent wake time, bedtime, routine length, soundscape, checklist state, or language choice, may be saved in your browser. You can clear this data in your browser settings or with the control below.
Google Analytics loads after the page becomes interactive. Before acceptance, and after rejection, Consent Mode keeps analytics storage denied and may send cookie-free traffic signals. Acceptance enables analytics cookies, tool-use events, Vercel Analytics and Vercel Speed Insights. Advertising consent stays denied. The calculators work with either choice.
This information is used to improve the user experience, performance, security, and reliability of Sleep Better Timer. It is not used to provide medical advice or build a personal sleep profile inside this app.

After acceptance, product events help identify broken flows and which tools visitors use. Events do not include entered sleep times, sleep duration, mood, sound choice or checklist contents. Cookie-free Google traffic signals may also be sent without acceptance.
The widget uses no analytics, cookies or saved inputs. Your website may have its own privacy policy. Only this dedicated embed can be framed; regular site pages remain protected.
Inputs stay in this page. Printing and calendar downloads happen on your device; inputs are not sent as analytics events.
If you send a message, the form collects your name, email address, message, and page URL, then sends them through an owner-controlled Cloudflare Worker to email. Cloudflare Turnstile helps reduce spam. The site itself does not create an account, payment record, or personal sleep profile from the message.
