The Stair Calculator (“we,” “us,” or “our”) operates thestaircalculator.com (the “Site”) and its web-based stair calculator (together, the “Service”). This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using the Service, you agree to the practices described here.
The short version
- The stair calculator runs entirely in your browser. The measurements you enter are never sent to or stored on our servers.
- You don’t need an account, and we don’t ask for personal information to use the calculator.
- We do not sell your personal information.
Information we collect
Information collected automatically
Like most websites, our hosting provider automatically records basic technical information when you visit, such as your IP address, browser type, device and operating system, the pages you request, the referring page, and the date and time. We use these server logs to keep the Site secure, diagnose problems, and understand overall traffic.
Information you provide
If you email us, we receive your email address, your name if you include it, and the contents of your message. We use this only to respond to you.
How we use information
We use information to operate, secure, and improve the Service; understand how the Site is used in aggregate; and respond to your messages. We do not use your information to make automated decisions about you.
Cookies
The calculator does not set cookies or save your measurements. Everything is calculated in your browser and is cleared when you leave the page. Third-party services described below, such as advertising, may use their own cookies.
Analytics
We may use analytics tools to understand aggregate usage, such as which pages are visited most. Where we do, the data is used in aggregate form to improve the Site, and we will update this policy to name the provider.
Advertising
We may display advertising served by third parties such as Google AdSense to keep the Service free. These providers may use cookies or similar technologies to show ads based on your visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this Site and other sites on the internet. You can opt out of personalized advertising at Google Ads Settings or learn more at aboutads.info. Where required by law, we will ask for your consent before personalized ads are shown.
Data sharing and disclosure
We do not sell your personal information. We share information only with service providers that help us run the Site (such as our hosting provider), and only as needed for them to provide their services. We may also disclose information if required by law or to protect the rights, safety, or property of our users, the public, or ourselves.
Security
We use reasonable technical and organizational measures, including HTTPS encryption, to protect information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
Data retention
We keep emails only as long as needed to handle your request and any follow-up. Server logs are kept for a limited period for security and troubleshooting.
Your rights and choices
GDPR, UK GDPR, and similar laws
Depending on where you live, you may have the right to access, correct, delete, or restrict the processing of your personal data, to object to processing, and to request a copy of your data. To exercise these rights, email [email protected].
California (CCPA/CPRA)
California residents may request access to and deletion of their personal information and may opt out of the “sharing” of personal information for cross-context behavioral advertising. We do not sell personal information. To make a request, email [email protected].
Children’s privacy
The Service is not directed to children under 13 (or under 16 where applicable). We do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us and we will delete it.
International users
Our service providers may process information in countries other than your own. Where required, we rely on appropriate safeguards to protect your information.
Third-party links
The Site may link to other websites. We are not responsible for their content or privacy practices, so please review their policies.
Changes to this policy
We may update this Privacy Policy from time to time. We will post the updated version on this page and change the effective date above. Your continued use of the Service after an update means you accept the revised policy.
