Privacy Policy
How arsenal.fit handles your data: calculator inputs stay on your device, plus our use of cookies and Google AdSense, and your privacy choices.
Last updated: 2026-06-13
This Privacy Policy explains what information arsenal.fit ("we", "us", the "Site") collects when you visit, how it is used, and the choices you have. We aim to keep this clear and honest. By using the Site you agree to this policy.
Who we are
arsenal.fit is an independent fitness-education website operated by Mustafa Bilgic. You can contact us via our contact page or at [email protected].
Information we collect
We deliberately collect as little as possible.
- Calculator inputs stay on your device. Every tool on this site (BMI, TDEE, one-rep max, body fat, protein, calories burned, the timer) runs entirely in your browser using JavaScript. The numbers you type are processed locally and are never transmitted to or stored on our servers.
- Standard server logs. Like most websites, our web server records basic technical data such as your IP address, browser type, the pages you request and timestamps. This is used for security and to keep the Site running.
- Analytics. We may use privacy-respecting analytics to understand which pages are popular and how the Site performs, in aggregate.
- Local storage. We store a small flag in your browser to remember your cookie-consent choice so we don't ask again on every visit.
Advertising & cookies (Google AdSense)
arsenal.fit is free because it is supported by advertising. We use Google AdSense and may use other advertising partners to display ads.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this Site and/or other sites on the internet.
- You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at aboutads.info/choices.
- For users in the EEA, UK and Switzerland, we present a consent banner. Your choice is recorded and we signal it to our advertising partners. You can change your choice at any time by clearing this site's data in your browser.
For more information about how Google uses data, see Google's Privacy & Terms.
Types of cookies used

Your choices & rights
Depending on where you live, you may have rights to access, correct, or request deletion of personal data, and to object to certain processing. Because we store almost no personal data ourselves, most requests relate to our advertising partners — use the opt-out links above to control ad personalisation. To exercise any right with us directly, contact [email protected].
Children
This Site is intended for adults and is not directed at children under 13 (or the applicable age in your country). We do not knowingly collect personal information from children.
Data security & retention
The Site is served over HTTPS. We retain server logs only as long as needed for security and operational purposes. Since calculator data never leaves your device, there is nothing for us to retain there.
Changes to this policy
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "last updated" date above. Continued use of the Site after changes constitutes acceptance.
