WeightPilot: GLP-1 Tracker — Privacy Policy

Last updated: 1 June 2026

This Privacy Policy explains what information the WeightPilot: GLP-1 Tracker mobile application ("WeightPilot", "we", "us") collects, how we use it, and the choices you have. WeightPilot is a personal tracking companion for people using GLP-1 medications.

WeightPilot is not a medical device and does not provide medical advice, diagnosis or treatment. It is a self-tracking tool only. Always follow the guidance of your own healthcare professional regarding your medication and health.

1. Information you provide

WeightPilot stores the information you choose to enter so it can be shown back to you in the app:

Account details: your name and email address, and a securely hashed password (if you register with email). We never store your password in readable form.
Sign-in identifiers: if you sign in with Google or with Apple, we store the identifier those services return to link your account. Apple only shares your name/email on the first sign-in.
Body measurements: weight and waist measurements you log, and your height and goal/target weight.
GLP-1 medication records: medication name, doses, injection dates, injection-site history and your injection schedule/reminder time.
Symptoms: symptoms and severity you record.
Food & nutrition: food and water logs, and nutrition information looked up from product barcodes, plus any meal plans you create.
Progress photos: photos you choose to add to track your progress.
Preferences: units, theme, reminder settings and onboarding responses.
Messages to the in-app AI coach: the questions you send to the optional AI coach.

2. Optional health & fitness data

If you enable it, WeightPilot may read step count and weight data from your device's health platform (for example Health Connect on Android) to display activity and weight trends. This is optional, is only accessed with your permission, and can be turned off in your device settings at any time. We do not read other health records.

3. Subscriptions & purchases

WeightPilot offers an optional premium subscription (monthly or yearly). Payments are processed by the Apple App Store or Google Play, and entitlement status is managed through RevenueCat. We receive your subscription status and renewal/expiry events so we can unlock premium features — we do not receive or store your full card or payment details. Where an alternative web payment method (PayPal) is offered, PayPal processes the payment and we store only a record that the purchase occurred.

4. How we use your information

To provide the app's core tracking features and show your data back to you.
To calculate trends, charts, weekly summaries and achievements.
To send the injection reminders you schedule (local notifications on your device).
To generate optional AI content (coach replies, daily insight, recipe and shopping-list suggestions) when you use those features.
To manage your account, subscription and password resets.
To keep the service secure and working correctly.

We do not sell your personal information, and we do not use your health or tracking data for advertising.

5. Third-party services

We share the minimum data needed with the following processors, only to deliver the features above:

Google Sign-In and Sign in with Apple — for optional social login.
AI provider (OpenAI, accessed via our integration platform) — when you use AI features, relevant context (such as your name, current/goal weight, protein goal and recent symptoms, or your typed message) is sent to generate a response.
Email delivery provider — to send password-reset emails.
Open Food Facts — when you scan a barcode, the barcode is sent to look up product nutrition information.
RevenueCat, Apple App Store, Google Play, PayPal — to process and manage subscriptions and purchases.

6. Data storage & security

Your data is stored in our secured database and transmitted over encrypted connections (HTTPS). Passwords are stored only as salted hashes. Access to stored data is restricted. No method of transmission or storage is 100% secure, but we take reasonable measures to protect your information.

7. Data retention

We keep your information for as long as your account is active. You can delete individual entries in the app at any time.

8. Deleting your account & data

You can permanently delete your account and all associated data (including weight, steps, doses, injections, symptoms, food logs and photos) directly in the app via Settings → Delete Account. This action is immediate and cannot be undone.

9. Children

WeightPilot is intended for adults and is not directed at children under 13 (or the minimum age required in your country). We do not knowingly collect data from children.

10. Your rights

Depending on your location, you may have rights to access, correct, export or delete your personal data. You can exercise the core of these rights directly in the app, or by contacting us using the details below.

11. 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 at the top of this page.
