Privacy Policy

Last updated: August 25, 2026

Your Privacy Matters

CalaiFitness takes privacy seriously. This policy explains how we handle information when you use our calculators, read our content, and view advertising on our website.

Data Storage

Calculator entries, measurements, and saved progress are processed and stored locally on your device using browser localStorage. We do not intentionally send the values you enter into calculators to our servers, Google Analytics, or advertising partners.

  • Body measurements and calculations remain on your device
  • Progress history is saved locally in your browser
  • Calculator-entry values are not intentionally sent to our analytics or advertising providers
  • Clearing browser data will remove your saved calculations

Information We Collect

Automatically Collected Information

We and our service providers may collect information automatically when you visit our website, including:

  • Browser type and version
  • Operating system
  • Pages visited and time spent
  • Referring website addresses
  • General location data (country/region level)

Information You Provide

When using our calculators, you voluntarily enter information such as height, weight, age, and activity level. This data is processed entirely in your browser and never leaves your device.

Cookies and Tracking

We use local storage, cookies, and similar technologies to:

  • Remember your theme preference (light/dark mode)
  • Store your calculation history locally
  • Track your daily streak progress
  • Measure site usage and performance through Google Analytics
  • Serve and measure advertising through Google AdSense and its partners

Google Analytics

We use Google Analytics to understand aggregate site traffic and improve our content and services. Google Analytics may collect information such as pages viewed, session activity, approximate location, browser and device information, and identifiers stored in cookies (for example, the _ga cookie). We do not intentionally send calculator entries, names, email addresses, or other directly identifying information to Google Analytics.

Google collects and processes this information under its own policies. You can learn more in Google's Privacy Policy and can limit Google Analytics measurement with the Google Analytics opt-out browser add-on.

Advertising and Google AdSense

We display advertising through Google AdSense. Third-party vendors, including Google, may use cookies, web beacons, IP addresses, and similar identifiers to serve, limit, measure, and report on ads based on a visitor's prior visits to this site and/or other sites. Google may use advertising cookies, including the DoubleClick DART cookie or equivalent technologies, to support these purposes.

Google and its partners may use these technologies to show personalized ads where permitted. Users can manage or opt out of personalized advertising in Google's Ad Center. You may also opt out of many participating companies' personalized advertising at aboutads.info. Opting out does not remove ads; it changes whether they are personalized.

Other third-party ad vendors or ad networks may also place or read cookies, use web beacons, or collect IP addresses as a result of ad serving on this website. Their handling of information is governed by their own privacy policies and controls.

Data Security

Since all personal fitness data is stored locally on your device, the security of this data depends on your device's security measures. We recommend:

  • Using secure, updated browsers
  • Keeping your device protected with passwords/biometrics
  • Being cautious on shared or public devices

Your Rights

You can manage local calculator data and browser-based tracking controls in several ways:

  • Access your data anytime through your browser's local storage
  • Delete your data by clearing browser storage or using calculator history features
  • Export your calculation history (if feature is available)
  • Stop using our service at any time without consequences
  • Manage advertising personalisation through Google's Ad Center and participating industry opt-out tools
  • Control or delete cookies through your browser settings

Children's Privacy

Our service is not directed to individuals under the age of 13. We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with information, please contact us.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
