Privacy Policy
Effective date: April 2026. Last updated: July 2026.
This Privacy Policy describes how Better Sleep Calculator (bettersleepcalculator.com) handles information when you use the site. Please read it carefully. By using the site, you acknowledge this policy.
1. Information We Collect
Calculator inputs: Time values, age group selections, and sleep latency preferences you enter into the calculator are processed entirely within your browser. These inputs are not transmitted to our servers, not stored in a database, and not associated with you personally. When you close or refresh the page, calculator inputs are cleared.
Contact form: If you use the contact form, it opens your email client using a mailto link. We receive your name, email address, selected subject, and message when you send that email. We use this information only to respond to your inquiry. We do not add contact form submissions to marketing lists.
Automatically collected data: Like most websites, our hosting infrastructure may collect standard server log data, including your IP address, browser type, pages visited, and timestamps. This data is used for security and basic analytics purposes. We do not use this data to identify individual users.
2. Cookies and Local Storage
No Local Storage: The calculator does not store your preferences or inputs in your browser's local storage or session storage.
Third-party cookies: This site may use Google AdSense to display advertising. Google AdSense and its advertising partners may use cookies and similar tracking technologies to serve ads based on your prior visits to this and other websites. These cookies are set by third parties, not by Better Sleep Calculator. You can manage or opt out of Google's use of cookies for ad personalization by visiting Google Ad Settings.
3. Analytics
If analytics tools are active on this site (such as Google Analytics), they may collect aggregated, anonymized data about how visitors use the site, including pages viewed, time spent, and general geographic region. We use this data to understand which content is most useful. If analytics are active, they are disclosed here. We do not share individually identifiable analytics data with third parties.
4. Advertising — Google AdSense
This site may participate in the Google AdSense program. Google AdSense uses cookies to serve ads based on a user's prior visits to this website and other sites on the Internet. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ad Personalization Settings. Third-party vendors, including Google, use cookies to serve ads based on prior visits to this website. You can also opt out through the Network Advertising Initiative opt-out page.
5. Data Retention
Calculator inputs are not retained — they exist only in your browser during your session. Contact form emails are retained in our email inbox and reviewed for the purpose of responding to inquiries. We delete emails that are no longer needed for this purpose. Server log data is retained according to our hosting provider's standard policies.
6. Children's Privacy
This site is intended for a general adult audience and is not directed at children under 13. We do not knowingly collect personal information from children under 13. The age group options in the calculator (including children's ranges) are provided for parents and caregivers planning on behalf of their children, not for children to use the site independently. If you believe we have inadvertently collected information from a child under 13, please contact us so we can take appropriate action.
7. Your Rights
Depending on your location, you may have rights related to your personal data, including the right to access, correct, or request deletion of personal information we hold about you. Because the calculator does not store personal data, these rights apply primarily to any contact form emails you have sent us. To exercise these rights, contact us at hello@bettersleepcalculator.com.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date at the top of this page. Continued use of the site after changes are posted constitutes acknowledgment of the updated policy.
