This Privacy Policy explains what information Proportion Calculator Free collects when you use our website, how we use it, and the choices you have. We keep it simple: our calculators run in your browser, we do not require an account, and we do not sell personal information.
Information We Collect
Calculator inputs: The numbers you type into a calculator are processed in your browser and are not sent to our server. Contact form: If you use the form on our Contact page, we receive the name, email address and message you provide, so we can reply to you. Comments: This site does not use comments. Technical data: Like most websites, our hosting provider may record standard server logs (such as your IP address, browser type and pages visited) for security and to keep the site running.
Cookies
We use only the cookies WordPress needs for the site to work, such as the login cookie for the site administrator. We do not use advertising cookies or cross-site tracking cookies. If you are logged in as an administrator, WordPress sets cookies to keep you signed in; ordinary visitors are not tracked by us in this way.
How We Use Information
We use contact-form messages only to answer you and to fix problems you report. We do not share your email address with third parties, we do not send marketing emails, and we do not use your messages for any other purpose. Server logs are used only for security, troubleshooting and aggregate statistics about how the site is used.
Data Retention and Your Rights
Contact-form messages are kept only as long as needed to answer them and to keep a record of reported errors. You may ask us at any time, through the Contact page, to delete a message you sent us, and we will do so unless we need to keep it for a legal reason. If you are in a region with data-protection rights, such as the European Union or the United Kingdom, you may also ask for a copy of the personal data we hold about you and for any inaccuracies to be corrected.
Changes to This Policy
We may update this policy when the site changes. The current version is always the one on this page. If you have questions about this policy, please use the Contact page.
