Privacy Policy
Last updated: 26 July 2026
TrainHubs ("the app") is a personal training platform available on the web at trainhubs.uk and through its companion iPhone and Apple Watch apps. This policy describes what data the app collects, why, where it lives, and how you can delete it.
What we collect
- Account data — your email address, display name and a password (stored only as a salted hash).
- Training data — your planned and completed workouts: strength sets, reps and weights; cycling power; running and swimming pace; heart rate and related workout metrics, including activities imported from services you connect (see below).
- Health data via Apple HealthKit — with your permission, the iPhone app reads heart-rate variability (HRV), resting heart rate, sleep and body mass to compute your daily training readiness. The Apple Watch app reads live heart rate and active energy during a workout, and writes your completed strength sessions back to Apple Health as workouts.
Health and fitness data is used solely for your own training analysis — readiness, progression and planning inside your account. It is never used for advertising or marketing, and never shared with anyone else.
Third-party connections you control
The app exchanges data with outside services only when you connect them, and you can disconnect each one at any time from your profile:
- Strava — imports your activities via Strava's authorised connection.
- Garmin — imports your activities and pushes your planned workouts to your Garmin device.
- Intervals.icu — using your own API key, relays your planned bike workouts so they appear in Zwift.
- Telegram — optional training reminders and summaries via a bot you link yourself.
Each connection sends or receives only the training data needed for that feature. We never pass your data to any service you have not connected.
Where your data lives
All data is stored on the app's own server (served from the UK domain trainhubs.uk), in a database that is separate for each user. For durability it is continuously replicated to encrypted cloud backup storage (Cloudflare R2). Data is transferred over HTTPS only.
No advertising, no tracking, no sale of data
The app contains no advertising, no third-party analytics and no tracking SDKs. We do not sell, rent or trade your data. This matches the Apple privacy manifest shipped with the iOS and watchOS apps, which declares that no collected data is used for tracking.
Deleting your account and data
You can delete your account and all associated data yourself, at any time, in the iPhone app under Settings → Delete Account (password confirmation required). Deletion removes your account and your training, health and connection data from the live service. You can also request deletion from the operator using the contact below.
