Data and AI — FitSync

AI transparency

Data & AI disclosure

This disclosure explains how FitSync uses AI, so you know you are interacting with a machine, not a human clinician. Last updated: 2 September 2026.

What MyCoach and SnapSync are

MyCoach is an AI coaching assistant. Paid subscribers get unlimited messages; FitSync Core includes a monthly allowance (currently 3 messages) without a subscription. It helps with programming, nutrition context, and progress questions using your FitSync logs.

SnapSync estimates calories and macros from a meal photo you take. Paid plans include this feature; Core includes a monthly scan allowance (currently 3).

Both are powered by a large language / multimodal model provided by Google LLC (Gemini API). They are not a human coach, doctor, physiotherapist, or licensed dietitian.

What we send to the model

When you send a MyCoach message, the request typically includes:

Your message and recent MyCoach conversation history
Relevant logs — recent workouts, food entries, bodyweight, goals — so the reply can use your context

When you run SnapSync, the meal photo and a short analysis prompt are sent to generate that scan result.

Traffic is encrypted (TLS). We have configured the provider relationship to opt out of using your data to train Google models. Provider-side retention is limited to generating that response.

Limitations

Not professional advice. Outputs can be wrong, incomplete, or outdated. Consult a qualified professional before significant training or diet changes, especially if you have an injury or medical condition.

Treat outputs as a starting point, not a prescription.
The model does not have live access to medical databases.
Do not share sensitive medical details (diagnoses, prescriptions) beyond what you need for fitness tracking.

Automated decisions (GDPR Art. 22)

MyCoach and SnapSync do not make decisions that produce legal or similarly significant effects on you. Outputs are suggestions you are free to ignore. They do not approve or deny accounts, prices, or refunds.

EU AI Act transparency

You are interacting with an AI system. This page, in-app labelling of MyCoach / SnapSync, and the Terms of Service are how we tell you that. FitSync does not use AI for biometric identification or to assess medical fitness for work.
