At Real Percent Calculator ("we", "us", "our"), your privacy is important to us. This Privacy Policy explains what information we collect, how we use it, and what rights you have. The short version: we collect almost nothing.
1. Information We Collect
Personal Data
We do not collect, store, or process any personal data. We have no user accounts, no sign-up forms, and no login system. The calculations you perform in the calculators exist only in your browser's memory and are never sent to any server.
Local Storage
We store one item in your browser's localStorage: your dark mode preference (either "light" or "dark"). This value never leaves your device and can be cleared at any time by clearing your browser's local storage.
Server Logs
Our hosting provider may automatically log standard web server data such as your IP address, browser type, referring URL, and pages visited. This data is used solely for operational purposes (security, uptime monitoring) and is not linked to any personal profile.
2. Cookies
We use cookies through Google Analytics to measure site usage (see Section 3). These are analytics cookies only — we do not use advertising cookies or social tracking pixels. The only first-party browser storage we set is localStorage for your dark/light mode preference, which never leaves your device.
You can control or delete cookies through your browser settings at any time.
3. Third-Party Services
Google Analytics
We use Google Analytics to understand how visitors use the Site — for example, which calculators are most used and how people find us. Google Analytics collects data such as your IP address (anonymised), browser type, device type, pages visited, and time spent on the Site. This data is processed by Google LLC and subject to Google's Privacy Policy.
Google Analytics uses cookies to distinguish users and sessions. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.
Bunny Fonts
We load web fonts from Bunny Fonts (fonts.bunny.net), a privacy-friendly font hosting service. No Google Fonts or other font tracking services are used.
4. Children's Privacy
Our site is a general-purpose math tool with no age restrictions, and we do not knowingly collect any data from anyone, including children under 13.
5. Links to Other Websites
Our site does not link to third-party websites beyond font hosting. If we add external links in the future, we are not responsible for the privacy practices of those sites and encourage you to review their privacy policies.
6. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date. Continued use of the site after changes are posted constitutes your acceptance of the revised policy.
