Privacy Policy

1. Overview & Client-Side Architecture

At Practical Tools (“we”, “our”, or “us”), privacy is a cornerstone of our architecture. Our calculators, estimators, and converters are designed to execute math client-side within your web browser. When you input sensitive data—such as financial sums, salaries, tip distributions, or dimensions—that data is processed locally by JavaScript on your machine. We do not store, intercept, or transmit your calculation parameters to our servers.

2. Information We Do Not Collect

We do not require user accounts, passwords, or personal registrations to use our calculators. You do not need to provide your legal name, physical address, or payment credentials.

3. Cookies, Web Beacons & Advertising Partners

Third-party vendors, including Google AdSense, may use cookies to serve ads based on a user’s prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visit to our site and/or other sites on the Internet.

Users may opt out of personalized advertising by visiting Google Ads Settings (https://www.google.com/settings/ads) or through opt-out portals like the Network Advertising Initiative (http://www.aboutads.info/choices/).

4. Standard Log Files

Like virtually all internet platforms, our hosting infrastructure may log standard non-personally identifiable technical telemetry (e.g., browser type, IP address, operating system, referring URL, time of request). This telemetry is utilized exclusively for server security, DDoS mitigation, and Core Web Vitals optimization.

5. Children’s Privacy

Practical Tools does not knowingly collect any personally identifiable information from children under the age of 13. If you believe your child has submitted personal information on our website, please contact us immediately.

6. Contacting Us Regarding Privacy

If you have questions or concerns regarding this privacy statement, you can contact our privacy officer at contact@practicaltools.org.
