Privacy Policy

Last updated: August 15, 2026

This Privacy Policy explains what data Evolution Force ("the App", "we") collects, how we use it, and what rights you have over it. By creating an account and using the App, you agree to the practices described here.

This document is not certified legal text — it's an accurate starting point based on what the App actually does today; we recommend having a lawyer review it before publishing, especially given the health data involved.

1. Who we are

Evolution Force is developed by Javier Collao. For any privacy questions, reach us at javiercollao8@gmail.com.

2. What data we collect

When you register and use the App, we collect:

• Account data: username, email address, password (stored encrypted, never in plain text).
• Physical and health data: weight, height, age, gender, body fat percentage, body type.
• Training and nutrition preferences: training goal, experience level, available training days/duration, available equipment, exercises you'd rather avoid, nutrition goal, diet type, dietary restrictions, meals per day.
• Workout history: exercises performed, sets, reps, weight lifted, reps in reserve (RIR), session duration.
• Progress records: body weight trend and personal records, automatically derived from your workout history.
• Basic technical data: information needed to keep you signed in (access token).

We do not collect location data, contacts, camera access, or access other apps on your device.

3. How we use your data

We use your data exclusively to:

• Create and maintain your account.
• Calculate your training and nutrition targets (calories, macronutrients, weight-progression suggestions).
• Automatically detect your personal records and show your progress.
• Adjust your training sessions based on how you're feeling that day (daily check-in) and substitute exercises based on available equipment or your preferences.
• Improve the App and fix bugs.

We do not use your data for advertising, we do not sell it, and we do not share it with third parties for commercial purposes.

4. Where your data is stored

Your data is stored in MongoDB Atlas (AWS infrastructure), and the App's server runs on Render. We take reasonable measures to protect this information from unauthorized access, including password encryption.

5. How long we keep your data

We keep your data for as long as your account is active. If you request account deletion, we delete your personal data within a reasonable timeframe, unless the law requires us to retain it longer.

6. Your rights

You have the right to:

• Access the data we hold about you.
• Correct inaccurate data (most of it can be edited directly from your profile in the App).
• Delete your account and data directly from the App (Profile → Delete Account) or by writing to javiercollao8@gmail.com.
• Export your data upon request.

To exercise any of these rights, contact us at javiercollao8@gmail.com.

7. An important note about health data

Evolution Force calculates calorie, macronutrient, and training estimates from the data you enter. These estimates do not constitute medical or professional nutrition advice. Talk to a healthcare professional before making significant changes to your diet or training, especially if you have a pre-existing medical condition.

8. Children

Evolution Force is not directed at children under 16. If you become aware that a minor has provided us with personal data, please contact us so we can delete it.

9. Changes to this policy

We may update this Privacy Policy from time to time. If we make significant changes, we'll notify you within the App or by email.
