Privacy Policy

Last updated: June 13, 2026

At FastCalc.tools, we prioritize the privacy and security of our visitors. This Privacy Policy document describes how we collect, use, and safeguard details about your visit.

1. Client-Side Calculation Processing

The core values, details, or math calculations you input on any calculator page on FastCalc.tools are processed **entirely client-side**. This means that any numbers, tax details, financial numbers, birthdates, or text strings you enter are calculated locally inside your web browser using JavaScript. We do not transmit, upload, save, or store this calculator input data on our servers.

2. Google Analytics Disclosure

FastCalc.tools uses **Google Analytics**, a web analysis service provided by Google LLC. Google Analytics gathers standard internet log information and visitor behavior data in an anonymous form (such as pages visited, average session duration, device type, and geographical location).

This information is compiled to analyze user interactions, traffic levels, and utility trends to help us improve the overall site experience. Google Analytics does **not** receive or record any data input into our online calculators.

3. Cookies & Tracking Technologies

Cookies are small data files placed on your computer or mobile device. We use cookies generated by Google Analytics to help monitor visitor counts and site speed. You can configure your web browser to reject cookies or warn you before accepting a cookie, though doing so might disable certain diagnostic statistics tracking.

4. Third-Party Services

We do not sell, trade, or otherwise transfer your personally identifiable traffic information to outside parties. This does not include trusted third parties who assist us in operating our website, conducting our business, or servicing you, so long as those parties agree to keep this information confidential.

5. User Rights

Since we do not collect any personal identifier accounts, user registrations, profiles, or calculator entries, we hold no user archives to access, modify, or erase. For any general inquiries regarding your rights under standard data privacy laws (like GDPR or CCPA) as they pertain to our analytics logs, please contact us.
