Privacy Policy

Last Updated: January 1, 2026

1. Introduction

Welcome to Flash calculator ⚡. We respect your privacy and are committed to protecting your personal data. This privacy policy will inform you as to how we look after your personal data when you visit our website (regardless of where you visit it from) and tell you about your privacy rights and how the law protects you.

2. The Data We Collect About You

Personal data, or personal information, means any information about an individual from which that person can be identified.

  • Usage Data: We may collect information about how you use our website, tools, and calculators. All calculations are performed locally in your browser, meaning we do not receive or store the inputs you provide to our calculators (e.g., your weight, your salary, or your passwords).
  • Technical Data: Includes internet protocol (IP) address, your login data, browser type and version, time zone setting and location, browser plug-in types and versions, operating system and platform, and other technology on the devices you use to access this website.
  • Cookies: We use cookies to enhance your experience. See section 4 below for more details.

3. How We Use Your Personal Data

We will only use your personal data when the law allows us to. Most commonly, we will use your personal data in the following circumstances:

  • Where we need to perform the contract we are about to enter into or have entered into with you.
  • Where it is necessary for our legitimate interests (or those of a third party) and your interests and fundamental rights do not override those interests.
  • To use data analytics to improve our website, products/services, marketing, customer relationships and experiences.

4. Cookies and Analytics

We may use Google Analytics or similar analytics providers to track and report website traffic. These providers may use cookies and similar tracking technologies to collect information about your activities on our website. You can set your browser to refuse all or some browser cookies, or to alert you when websites set or access cookies.

If we display advertisements, our advertising partners may use cookies to serve ads based on your prior visits to our website or other websites.

5. Data Security

We have put in place appropriate security measures to prevent your personal data from being accidentally lost, used or accessed in an unauthorised way, altered or disclosed. Because our core tools process data strictly client-side (in your browser), sensitive calculation data never reaches our servers.

6. Third-Party Links

This website may include links to third-party websites, plug-ins and applications. Clicking on those links or enabling those connections may allow third parties to collect or share data about you. We do not control these third-party websites and are not responsible for their privacy statements.
