Privacy Policy

FitKit — BMI, Calorie & Fitness Calculator  ·  Effective date: 15 July 2026

✓ Works offline ✓ No account required ✓ Data stays on your device

1. Introduction

This Privacy Policy describes how the FitKit mobile application ("the App", "we", "us") handles your information. FitKit is a collection of fitness and health calculators (BMI, calories, macros, one-rep max, fasting planner and more) designed to work locally on your device. We built FitKit to collect as little data as possible.

By using the App you agree to the practices described in this policy.

2. Information Stored Only on Your Device

To perform its calculations, the App asks for details such as:

All of this information is stored locally on your device only. It is never uploaded to our servers, never sold, and never shared with anyone. If you uninstall the App, or use the "Start over" option inside Settings, this data is permanently deleted from the device.

3. Information You May Choose to Share With Us

During onboarding, the App offers an optional form where you may share your full name, email address and telephone number in exchange for personalised health suggestions. This step is completely skippable and the App works fully without it.

If you choose to submit this form, the information is transmitted securely and stored in Google Firebase (Cloud Firestore). We use it only to:

We do not sell this information. You may request its deletion at any time by contacting us at the email address in Section 10, and we will delete it within 30 days.

4. Advertising (Google AdMob)

The App is free and supported by advertising served by Google AdMob. The App shows occasional interstitial ads and optional rewarded ads (which you choose to watch to unlock features such as Pro Insights or an ad-free period).

AdMob, as a third-party advertising provider, may collect and use:

This collection is governed by Google's own policies. Please review:

You can opt out of personalised advertising at any time in your device settings: on Android under Settings → Google → Ads, and on iOS under Settings → Privacy & Security → Tracking.

5. What We Do NOT Collect

In short: your health and fitness data stays on your phone. The only personal data we ever receive is the name, email and phone number you may voluntarily submit — and you can skip that entirely.

6. Data Retention & Deletion

7. Security

Data you submit through the optional contact form is transmitted over encrypted connections (HTTPS/TLS) and stored in Google Firebase, which maintains industry-standard security certifications. On-device data is protected by your device's own security (screen lock, encryption). No method of electronic storage is 100% secure, but we minimise risk by simply not collecting data we do not need.

8. Children's Privacy

The App is not directed at children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from children. Ad content is rated for general audiences (PG or below). If you believe a child has submitted personal information through the contact form, please contact us and we will delete it promptly.

9. Not Medical Advice

FitKit provides estimates based on general, well-established formulas (such as BMI, Mifflin-St Jeor and the US Navy body fat method). Results are for informational purposes only and are not medical advice, diagnosis or treatment. Always consult a qualified health professional before changing your diet, exercise, fasting or sleep routine, especially if you are pregnant, have a medical condition or take medication.

11. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the App after changes means you accept the revised policy.
