Information We Collect

Our Fitness Calculator processes your personal information locally in your browser. We collect:

  • Personal metrics you enter (age, weight, height, etc.) - stored locally on your device
  • Suggestions you voluntarily submit through our feedback form
  • Online activity (e.g. pages visited, time spent)
  • Cookies to store the user's preferences and settings
  • Analytics data that tells me how your experience is going (e.g. feature usage, performance)
  • Your IP address and approximate location (e.g. country and city), used for analytics and abuse prevention
  • A first-party cookie that remembers how you first reached the site (e.g. search engine or referral), used to measure what brings visitors here

How We Use Your Information

  • Calculate your personalized fitness metrics
  • Improve our calculator based on usage patterns
  • Respond to your suggestions and feedback
  • Vercel Analytics to improve my services.

Data Storage

Your personal fitness data is stored locally in your browser's localStorage and is never transmitted to our servers. This means your sensitive information stays on your device and is completely private.

Third-Party Services

We use the following third-party services:

  • Google AdSense: Displays ads that help keep the site free. Google and its partners may use cookies and similar identifiers to serve and measure ads (see “Advertising” below)
  • Google Analytics: Aggregated website usage analytics
  • Vercel Analytics & Speed Insights: Privacy-friendly usage and performance analytics
  • Discord: For processing suggestions (name and message only)

Your Rights

Since your data is stored locally, you have complete control. You can clear your browser's localStorage at any time to remove all stored information. You can also disable cookies and analytics tracking through your browser settings. I never store or process any personal data on my servers and I do not share your data with third parties. You can also request that I delete any personal data I may have about you by contacting me directly.

Advertising (Google AdSense)

We use Google AdSense to display ads, which helps keep this site free for everyone.

  • Third-party vendors, including Google, use cookies and similar technologies 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 visits to our site and/or other sites on the internet.
  • You can opt out of personalized advertising in Google Ads Settings, or opt out of some third-party vendors’ cookies at aboutads.info/choices.
  • Visitors in the EEA, UK, and Switzerland: we present a consent banner (via a Google-certified consent management platform) before serving personalized ads or setting non-essential cookies. You can accept, reject, or manage your choices there, and change them at any time.
