Privacy Policy
Last updated: July 2, 2026
This policy explains what information CalcPerch ("we", "us") does and does not collect when you use calcperch.com, and the choices you have.
What we don't collect
The numbers you enter into our calculators — dates of birth, weights, loan amounts, or anything else — are processed entirely in your browser. They are never transmitted to, stored on, or seen by our servers. We do not require accounts, and we do not ask for your name or email to use any tool.
Information collected automatically
Like nearly all websites, our hosting provider may log basic technical data when pages are served — such as IP address, browser type, and pages requested — for security and to keep the site running. These logs are not used to identify individual visitors.
Cookies and advertising
CalcPerch is funded by advertising. We use Google AdSense to display ads:
- Third-party vendors, including Google, use cookies to serve ads based on your prior 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/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ad Settings, or opt out of some third-party cookies at www.aboutads.info.
For visitors in the European Economic Area and the UK, ads are served in accordance with applicable consent requirements.
Analytics
We may use privacy-respecting analytics to understand which tools are useful (e.g., page view counts). Any analytics we use are configured without cross-site tracking wherever possible.
Links to other sites
Some pages link to external websites. We are not responsible for the privacy practices of other sites and encourage you to read their policies.
Children's privacy
CalcPerch is a general-audience site and does not knowingly collect personal information from children under 13.
Changes to this policy
If we change this policy, we will update this page and the date above. Significant changes will be noted on the homepage.
