Privacy Policy

Last Updated: February 2026 | Version 2.0

1. Introduction

At Aegis Endurance, we are committed to protecting your privacy while providing the most advanced, AI-driven coaching experience in the world. This policy explains how we collect, use, and protect your data, specifically regarding our integration with wearable devices, health platforms, and our proprietary AI coaching engine.

This Privacy Policy complies with the UK General Data Protection Regulation (UK GDPR), the Data Protection Act 2018, and the requirements of our third-party integration partners, including the Garmin Connect Developer Program.

2. Information We Collect

To provide personalised, adaptive training plans, Aegis Endurance collects the following categories of data:

  • Identity and Contact Data: Name, email address, and date of birth.
  • Physical & Demographic Data: Height, weight, and gender.
  • Sensitive Health & Life Stage Data (Optional): To provide tailored coaching for female athletes, users may optionally provide data regarding their menstrual cycle or life stage (e.g., peri-menopause, menopause). This data is used exclusively to adjust training intensity and recovery recommendations based on hormonal fluctuations.
  • Lifestyle & Profile Data: Training goals, event dates, available training hours, and lifestyle factors (e.g., perceived stress levels, occupational physical activity).
  • Biometric & Performance Data: We ingest high-fidelity data from your connected devices, including heart rate (resting and active), Heart Rate Variability (HRV), sleep duration and quality, respiratory rate, and functional threshold power (FTP).
  • Activity Data: Data contained within .FIT files or activity logs, including GPS coordinates, power output, cadence, pace, and perceived exertion.

3. External Platform & Wearable Integrations

Aegis Endurance allows you to connect your account with third-party fitness platforms to create a seamless, "closed-loop" training experience.

3.1 Garmin Connect™ Integration

We offer a primary integration with the Garmin Connect™ platform through the Garmin Connect Developer Program. If you choose to link your Garmin account:

Data We Send to Garmin:

  • Structured, AI-generated workouts pushed directly to your Garmin Connect calendar

Data We Receive from Garmin:

  • Completed activity data to analyse performance against your plan
  • Recovery and wellness markers (Sleep, Resting Heart Rate, HRV)
  • Menstrual Cycle data (where you have granted permission within Garmin Connect)

3.2 Important Notice Regarding Garmin Data Transfers

By connecting your Garmin account to Aegis Endurance, you acknowledge and consent to the following:

  • Your data will be transferred between Aegis Endurance and Garmin International, Inc.
  • Garmin processes your data in accordance with their own privacy policy, available at: https://www.garmin.com/privacy/connect
  • You should review Garmin's privacy policy before connecting your account
  • If you are subject to any restrictions that prevent you from sharing your data with third parties, you must not connect your Garmin account to Aegis Endurance

Data Controller Status: Aegis Endurance and Garmin International, Inc. operate as independent data controllers. Each party is separately responsible for compliance with applicable data protection laws regarding the data they process.

3.3 Future Integrations

As Aegis Endurance expands, we may add support for additional third-party platforms. You will always have full control over which platforms are connected and what data is shared.

3.4 Data Control & Disconnection

You may disconnect any third-party integration at any time through your Aegis account settings. Disconnecting will stop future data transfers but will not automatically delete historical data already processed by Aegis Endurance (see Section 10 for deletion requests).

4. How We Use Your Data

Our proprietary AI ecosystem uses your data for the following purposes:

  • The Coaching Supervisor: Our AI analyses your health, sensitive physiological data, and performance data to generate and adapt your weekly training schedule.
  • Hormonal & Life Stage Adaptation: For athletes providing menstrual cycle or life stage data, our AI adjusts training load to optimise for physiological readiness and mitigate injury risk.
  • Execution Scoring: We compare "planned vs. actual" metrics to score your workout execution and adjust future progressions.
  • Recovery Optimisation: We use biometric markers to detect fatigue and automatically suggest rest or intensity reductions.

5.2 Third-Party AI Model Providers

Important: AI Model Provider Data Usage

Aegis Endurance uses Google's AI services (Gemini) to power our coaching intelligence. We want to be completely transparent about how your data is handled:

  • No training on your data: Google does not use your personal data, training information, or any content processed through Aegis Endurance to train their AI models when accessed via their API.
  • API-only access: Your data is processed via secure API calls and is not retained by Google beyond the immediate processing of your request.

  • Your Individual Data: Your personal training data may be used to refine and improve AI recommendations only with your explicit consent. You may grant or withdraw this consent at any time (see Section 5.5).

5.4 Automated Decision-Making

Your training plan is primarily managed by our multi-agent AI architecture. These automated decisions include:

  • Adjusting workout intensity based on recovery metrics
  • Rescheduling sessions when fatigue indicators are elevated
  • Modifying training volume in response to execution scores
  • Triggering protective interventions via our "Shielding Protocol"

Your Rights Regarding Automated Decisions: Under UK GDPR, you have the right to obtain human intervention in significant automated decisions, express your point of view, and contest decisions made solely by automated processing.
