Privacy Policy
Last updated: October 2026
TirePuller (“we”, “us”) is a training platform designed for endurance and expedition-focused athletes. This Privacy Policy explains how we collect, use, and protect personal and training data.
AI Transparency Statement
TirePuller's Expedition Assistant uses artificial intelligence (AI) provided by OpenAI. This statement explains what the AI does with your data and how you stay in control.
What the AI does. When you ask the Expedition Assistant to analyze a training session, a summary of your latest session is sent to OpenAI, which writes a plain-language estimate of how that effort compares with distances in polar expedition conditions. When you ask an expedition question, your question is sent to OpenAI together with approved TirePuller expedition material. Answers are generated automatically and can contain errors.
What is sent. For a session analysis: distance, duration, average speed, elevation gain, surface, number of tyres or pulled load, whether rollerskis were used, and effort figures calculated from these. If the session was imported from Garmin, the Garmin device model is included so that the answer can credit Garmin. Text you type into a question is also sent. Your GPS route, heart rate data, name, email address and other account details are not sent.
No AI training. TirePuller does not use your data, including Garmin data, to train AI models, and uses OpenAI's service only to generate the response to your request.
Your consent. AI processing starts only after you have given your explicit consent in the Expedition Assistant, and only when you ask for an analysis or send a question. You can withdraw your consent at any time under Settings > Expedition Assistant (AI). After withdrawal no further data is sent to OpenAI, and the Expedition Assistant is unavailable until you consent again. Withdrawal does not affect processing that has already taken place.
Garmin data. Data from your Garmin device is processed by AI only for the purpose described above and only after your consent. AI results based on it are shown with a Garmin attribution.
Changes. We update this statement when our use of AI, applicable law or Garmin's requirements change, and we ask for your consent again if the purpose or scope of AI processing changes materially.
1. Data We Collect
TirePuller collects training data provided directly by users or imported from connected third-party services, including Garmin.
The app may also store account information such as email address, name or nickname, country, year of birth, saved routes, group posts, expedition provider details, subscription entitlement status, and app settings when users choose to provide them.
Collected training data may include:
- Distance
- Duration
- Elevation gain
- GPS route and precise location points when route recording is enabled
- Heart rate metrics
- Activity timestamps
- Derived fitness metrics (such as VO₂max, where available)
2. Garmin Data
If a user chooses to connect their Garmin account, TirePuller receives activity data via the Garmin Activity API.
Garmin data is used solely to:
- Display training sessions within the TirePuller app
- Analyze training load and performance trends
- Provide training insights to the user
TirePuller does not access real-time data. Only activities explicitly shared by the user are processed.
When you ask the Expedition Assistant to analyze a Garmin-derived training session, and only after you have given your explicit consent, relevant training details such as distance, duration, elevation gain and surface are sent to OpenAI, a third-party AI service, to generate that analysis (see the AI Transparency Statement above). Garmin data is never sold, rented, or shared with third parties for advertising or marketing purposes.
3. Data Usage
Training data is used exclusively for training analysis, performance insights, expedition simulation, and progress tracking.
Personal and activity data is never sold, rented, or shared with third parties for advertising or marketing purposes.
If a user explicitly chooses to share training with an expedition agency, TirePuller may include that user and their training data, including sessions imported from Garmin, in a preparation report for that agency. Garmin-derived sessions are identified as originating from Garmin in the report.
4. Subscriptions and Purchases
TirePuller uses Apple in-app purchases and RevenueCat to manage Premium access, purchase restoration, and subscription status.
Payment details are handled by Apple. TirePuller stores subscription entitlement status so the app can unlock Premium features.
5. Expedition Assistant
Premium users may send training context and questions to the Expedition Assistant.
Assistant requests are processed through TirePuller backend services and OpenAI to generate responses based on TirePuller expedition material and the user training context needed for the request.
Monthly assistant usage counts may be stored to enforce fair-use limits.
AI processing requires your explicit consent, which you can withdraw at any time in the app under Settings > Expedition Assistant (AI). See the AI Transparency Statement above.
6. Data Storage and Security
TirePuller stores app data in Supabase and uses access controls intended to restrict user-owned data to the account that owns it.
Access to personal data is restricted to systems required to operate TirePuller, provide support, process subscriptions, import Garmin data, and run the Expedition Assistant.
7. User-Generated Content and Moderation
Group messages are stored as user-generated content and may be visible to other members of the same group.
Users can report group messages and block other users. Reported content may be reviewed by TirePuller for safety, abuse prevention, and moderation.
8. Data Retention and Deletion
Users may request access to their stored data, correction of inaccurate data, or permanent deletion of their data at any time.
Users can initiate account deletion from the TirePuller app settings. Account deletion removes the TirePuller account and associated app data, but Apple subscriptions must be canceled separately in Apple subscription settings.
Privacy-related requests can also be made by contacting us using the email address below.
9. User Control
Users may disconnect their Garmin account at any time. Once disconnected, no new Garmin data will be collected.
Users may withdraw their consent to AI processing at any time under Settings > Expedition Assistant (AI).
Users may remove expedition provider details from their profile at any time.
Users may restore purchases or manage subscriptions from the app where subscription support is available.
