Privacy Policy

Last updated: November 2026. Plain-English terms regarding your personal data and in-browser computing.

At pocket-calculator.com, your privacy is a foundational design requirement rather than an afterthought. We believe that doing everyday math—whether tallying personal debts, budgeting family expenses, or calculating restaurant tips—should remain completely private to you.

1. Client-Side Execution (Your Numbers Stay on Your Device)

Every calculation executed on our website (including the pocket calculator, percentage calculator, discount calculator, tip calculator, sales tax calculator, and fraction calculator) runs 100% within your local web browser using client-side JavaScript.

We do not operate a computational backend server that receives your mathematical inputs. When you type numbers into any tool or store totals in calculator memory registers, that data resides entirely within your device's temporary memory (RAM). It is never transmitted across the internet to our servers or any third-party database.

2. No Cookies, No Beacons & No Account Tracking

pocket-calculator.com does not set persistent tracking cookies, marketing beacons, canvas fingerprints, or cross-site advertising scripts. You do not need to register an account, submit an email address, or provide personal credentials to use any feature on this website.

3. Web Server Logs

Like virtually all websites hosted on modern internet infrastructure (such as Cloudflare Pages), standard non-personally identifiable diagnostic server logs may be generated when your browser requests web assets (such as HTML, CSS, or font files). These logs typically include your IP address, browser type, operating system, and the timestamp of the asset request. We utilize these standard infrastructure logs solely for DDoS protection, network performance optimization, and server security.

4. External Links

Our informational articles may occasionally reference official government revenue websites (such as state Departments of Revenue or the Tax Foundation). We are not responsible for the privacy practices or content of external third-party websites.

5. Children's Privacy (COPPA Compliance)

Our services are designed for general audiences and do not knowingly collect personal information from children under the age of 13 in compliance with the Children's Online Privacy Protection Act (COPPA).

6. Changes to This Policy

We reserve the right to update this privacy policy as our tools evolve. Any updates will be published directly on this page with an updated modification date.
