Privacy Policy

Last updated: July 6, 2026

Luntrack ("we," "us," or "our") operates the Luntrack fitness and nutrition tracking application. This Privacy Policy explains how we collect, use, and protect your personal information when you use our service at luntrack.com.

By using Luntrack, you agree to the collection and use of information in accordance with this policy.

Information We Collect

Account information: When you register, we collect your username, email address, and password (stored as a secure hash).

Profile and health data: To provide personalized recommendations, we collect data you enter including age, gender, weight, height, fitness goals, activity level, and training experience.

Usage data: We collect information about how you interact with the app — workouts logged, meals tracked, AI chat messages, and session activity.

Payment data: Subscriptions are processed by Stripe, Inc. We do not store your full card number or payment credentials. Stripe may store billing details per their own privacy policy.

Technical data: We automatically collect your IP address, browser type, device type, and approximate location (country level) for security and analytics.

How We Use Your Information

  • To provide, personalize, and improve the Luntrack service
  • To calculate macros, TDEE, and generate AI-powered fitness recommendations
  • To process payments and manage your subscription
  • To send transactional emails (account verification, password reset, receipts)
  • To detect and prevent fraud, abuse, or security incidents
  • To comply with legal obligations

We do not sell your personal data to third parties. We do not use your data for advertising.

Data Sharing

We share your data only with trusted service providers necessary to operate Luntrack:

  • Stripe — payment processing (stripe.com/privacy)
  • Google — optional Google Sign-In authentication (policies.google.com/privacy)
  • Groq, Claude AI (Anthropic), Authopia AI — processing AI chat and nutrition analysis requests (messages may be transmitted to these APIs; we do not use them for model training)
  • Hosting provider — cloud infrastructure to run the application

We may also disclose data if required by law or to protect the rights and safety of users or the public.

Cookies and Local Storage

Luntrack uses:

  • Session cookies — to keep you logged in (HTTP-only, secure)
  • Browser local storage — to store your display preferences (language, units, cached data) on your device

We do not use tracking cookies or third-party advertising cookies.

Data Retention

We retain your account and health data for as long as your account is active. If you delete your account, we delete your personal data within 30 days, except where we are required to retain it by law (e.g., payment records for tax purposes, typically 7 years).

Your Rights

Depending on your location, you may have the following rights regarding your personal data:

  • Access — request a copy of the data we hold about you
  • Correction — update inaccurate data (available in Settings)
  • Deletion — request deletion of your account and data
  • Data portability — request your data in a portable format
  • Opt-out — unsubscribe from marketing communications at any time
EU/EEA users (GDPR): If you are located in the European Union or European Economic Area, you have additional rights under the General Data Protection Regulation. The legal basis for processing your data is the performance of our contract with you and our legitimate business interests. You may lodge a complaint with your local supervisory authority.

To exercise any of these rights, contact us at privacy@luntrack.com.

Children's Privacy

Luntrack is not intended for users under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

Security

We use industry-standard security measures including HTTPS encryption, HTTP-only secure cookies, bcrypt password hashing, and access controls. However, no method of transmission over the Internet is 100% secure. We cannot guarantee absolute security of your data.

The Luntrack Mobile App

This Privacy Policy also covers the Luntrack mobile application for iOS and Android. The app is an extension of the same service — your account and data are shared with the website, and everything above applies equally. In addition, the app can access the following data, in every case only after you grant the corresponding system permission:

Health and activity data (Apple Health / Health Connect): with your permission, the app reads your daily step count to show activity statistics, streaks, and estimated calories burned. This data is synced to your account solely to provide these features. Health data is never used for advertising or marketing, never sold, and never shared with third parties.

Location (run tracking): the app uses your precise location only while you are recording a run, to measure distance, pace, and route — including in the background with the screen off during an active run. Tracking stops the moment you finish the run, and location is not collected at any other time. Your routes are stored in your account and are visible only to you.

Camera and photos: used to scan product barcodes and to analyze meal photos with AI. Meal photos are transmitted for one-time analysis only — they are not permanently stored on our servers and are not used to train AI models.

Leaderboard videos: if you choose to submit a personal-record video, it is uploaded to secure storage and checked by an automated verification system (and, where needed, a human moderator). Approved videos are visible to other Luntrack users on the leaderboard. You may request removal of your video at any time.

On-device storage: the app keeps a local cache of your data (workouts, meals, settings) on your device so it keeps working offline. The cache is removed when you sign out or uninstall the app.

Notifications: if you enable push notifications, we store a device token used solely to deliver them. You can disable notifications in your device settings at any time.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will post the new policy on this page with an updated date — and for any material change we will also email every registered account a summary of what changed. Continued use of Luntrack after changes constitutes acceptance of the new policy.
