Cookie Policy
Last updated: March 7, 2026
Short version: FitFuel Tools uses a small number of cookies — primarily for analytics (to understand how people use the site) and advertising (Google AdSense). All health calculations happen entirely in your browser and no personal health data is ever stored in cookies or transmitted to our servers.
1. What Are Cookies?
Cookies are small text files stored on your device (computer, phone, or tablet) when you visit a website. They are widely used to make websites work correctly, remember your preferences, and provide information to site owners about how their site is being used.
Cookies cannot access other files on your device, run programs, or transmit viruses. They are simple text files that can only be read by the website that placed them.
2. What Cookies Does FitFuel Tools Use?
We use the following categories of cookies:

3. What We Do NOT Store in Cookies
We want to be clear about what our cookies do not contain:
- No health data — your weight, height, age, or any calculation inputs are never stored in cookies or sent to our servers.
- No calculator results — all calculations happen entirely in your browser and are not transmitted anywhere.
- No passwords or financial information — we have no accounts or payment systems.
- No sensitive personal data of any kind.
4. How to Control Cookies
You have the right to control which cookies are placed on your device. You can:
Browser settings
Most browsers allow you to block or delete cookies via their settings. Note that blocking all cookies may break some website functionality.
Google Analytics opt-out
Install the Google Analytics Opt-out Browser Add-on to prevent your data from being used by Google Analytics across all websites.
Advertising opt-out
Manage personalised ad preferences at Google Ad Settings. Note that opting out of personalised ads does not remove ads — it means the ads shown to you will be less relevant to your interests.
5. Third-Party Cookies
