Privacy Policy
TrainingLab · Last updated: 9 July 2026
In short: TrainingLab is built to keep your data yours. Your workouts and
health data stay on your device and in your own private iCloud. There is no analytics server,
no advertising, and no third-party tracking. The app's intelligence features run entirely on
your device using Apple's on-device models.
Who we are
TrainingLab (“the app”, “we”) is a workout-tracking app for iPhone and Apple Watch. This policy
explains what data the app uses and how. If you have questions, contact us at
justus.besser@online.de.
Data the app uses
- Workouts, exercises and plans you create. Stored on your device with
SwiftData and synced through your personal iCloud account (see below). We never receive them.
- Health & fitness data (HealthKit). With your permission, the app reads
heart rate, active energy, distance, steps, and — for the recovery features — heart-rate
variability, resting heart rate, and sleep. It writes completed workouts (and related
heart-rate/energy/distance samples) back to Apple Health. This data is processed
only on your device.
- Apple Music (MusicKit). If you use the in-app player, the app accesses your
Apple Music library and playback state to show and control what's playing. This happens
through Apple's frameworks; we do not receive your listening history.
On-device intelligence
TrainingLab's readiness score, personalized workout generation, difficulty prediction, and the
“Describe a workout” feature are computed on your device. The natural-language parts use Apple's
on-device Foundation Models (Apple Intelligence). Your health signals and training history are
analyzed locally and are never uploaded to us or any third party for these
features. These features are provided for general fitness guidance and are not medical advice.
iCloud sync
Your workouts, exercises, and plans sync across your devices using Apple's CloudKit in your own
private iCloud database, tied to your Apple ID. We have no access to this data,
and it is governed by
Apple's Privacy Policy. You can disable
iCloud sync in your device's iCloud settings.
What we do NOT do
- We do not collect analytics or usage data on our own servers.
- We do not use any third-party advertising or tracking SDKs.
- We do not sell, share, or transmit your health data.
- There is no account to create — you use your existing Apple ID.
Notifications
If you enable reminders, the app schedules local notifications on your device. No notification
content is sent to an external server.
Your control
- Revoke Health access anytime in Settings → Privacy & Security → Health → TrainingLab.
- Revoke Apple Music access in Settings → TrainingLab.
- Delete your data by deleting workouts/plans in the app, or by removing the app and its
iCloud data from your Apple ID.
Children
The app is not directed to children under 13 and does not knowingly collect their data.
Changes
We may update this policy as the app evolves. Material changes will be reflected here with a new
“last updated” date.
