Last updated 5 October 2026
over-sight is a training coach that works on your intervals.icu account. It is operated by Barhatch Ltd. This page says what we keep, why, and what you can do about it.
What we keep
- Your intervals.icu access token, encrypted, so the coach can read your training and write workouts you've approved. Disconnecting or deleting your data removes it and revokes it at intervals.icu.
- Your athlete ID, name and timezone from intervals.icu.
- Your coaching files: your playbook, training log, the coach's notes and a short record of recent chat.
- Your conversations with the coach, and a record of each step it took (what it read and changed), so you can see its work and we can fix problems.
- Changes you approved or rejected, usage and cost, and a log of account actions.
The training data the coach reads includes activities and wellness data such as heart rate, HRV, sleep and weight, as well as anything you tell it about injuries.
How it's used
Only to coach you: to plan and adjust your training, run your weekly review and answer your messages. We don't train AI models on your data, and we don't sell or share it for advertising.
To write its replies, the coach sends your messages and the training data it reads to Anthropic's API, which processes it to respond. Your data is stored on Google Cloud in the United States (us-west1).
Activity data may come from Garmin devices; where we show it, we say so. We never change your calendar without your approval, and we never delete completed activities.
Your choices
From the app's Privacy page you can download everything we hold about you, disconnect intervals.icu, or delete all of it at any time. Deleting removes your account, files, conversations and token here and revokes our access at intervals.icu; your intervals.icu account and calendar are not touched.
