• Location (GPS): to record your route, distance and speed during an activity (running, cycling, etc.).
• Background location: only to keep recording an activity when the app is not in the foreground (screen off, another app, locked).
• Bluetooth: to connect to sensors (heart-rate strap, cadence, power…).
• Physical activity: to improve activity tracking and some training-related metrics.
• Microphone: if you enable voice coaching / voice commands, to detect your commands and interact during training.
• Sound / audio: to play spoken announcements (text-to-speech), alerts and training cues through the speaker or headphones.
• Background microphone: only if you enable voice commands during an activity, so you can trigger a command even when the screen is locked or the app is not in the foreground.
• Camera (if enabled): only for the PPG feature (measurement via camera).
• Notifications: for training reminders, alerts and important information.
• Files / media access (if requested): to import activity files (GPX/TCX/FIT) and manage some local content.
• Send SMS (SOS mode): during a workout, if you press the SOS button, AI-Training can send an SMS to your configured emergency contacts. The message may include your location (if location is allowed) and/or a location link. No SMS is sent without your action (pressing SOS) and the app does not read your SMS. Carrier SMS fees may apply.

You stay in control: you can refuse some permissions and change them anytime in your device settings. Some features may then be limited.
