Privacy Policy
Last updated: October 2026. Multiple Tools Pro is engineered around the principle of zero data retention and client-side computational privacy.
1. Our Commitment to Client-Side Computing
At Multiple Tools Pro (accessible via multipletoolpro.com), we believe your health statistics, financial figures, and personal calculations belong solely to you. All calculation logic across our 19 online tools is executed locally inside your web browser via client-side JavaScript.
When you enter numbers into our calculators (including BMI values, body fat circumferences, salaries, 401(k) balances, investment returns, or academic grades), that data is never transmitted to, processed by, or stored on our servers.
2. Information We Do Not Collect
- No Financial Data: We do not collect, view, or log account balances, interest rates, mortgage amounts, debt figures, or investment allocations.
- No Health or Biometric Data: We do not log height, weight, gender, age, calorie targets, or physical strength metrics.
- No User Accounts: Multiple Tools Pro requires no sign-up, registration, passwords, or profile creation.
3. Information We May Collect Automatically
Like most web operators, we collect non-identifiable technical server logs generated by standard web browsers to ensure site stability, performance, and security. This may include:
- Browser type and version
- Operating system
- Referring URLs and timestamps
- Standard server request codes (e.g. HTTP 200, 404)
4. Cookies & Local Storage
Multiple Tools Pro does not deploy tracking cookies for behavioral profiling. Any local browser storage utilized by our tools is strictly restricted to temporary session parameters (such as preserving calculator unit preferences like Metric vs. Imperial) within your own device.
5. Third-Party Services & Links
Our website may contain links to external reference materials, such as official CDC guidelines, WHO documentation, or IRS publication tables. Once you navigate away from multipletoolpro.com, you are governed by the privacy policies of those external domains.
6. Children’s Online Privacy Protection (COPPA)
Because our math and education calculators are widely used by students, we strictly adhere to children’s privacy standards. We do not knowingly solicit or store personal identifiable information from anyone under the age of 13.
