Privacy Policy · Mentz Coach

Mentz (mentz.io) provides software that personal trainers (“Coaches”) use to deliver coaching to their clients. For client coaching data, the Coach is the data controller and Mentz acts as their data processor. For Coach account data, Mentz is the controller.

What we collect

Account data: name, email address, password (hashed), profile photo, phone number.
Coaching data you submit: onboarding answers, daily check-ins (weight, sleep, energy, hunger, mood, soreness, steps, resting heart rate, supplement use), workout logs and messages.
Health data: injuries, medical conditions and medications you choose to share. This is special category data processed only with your explicit consent, which you can withdraw at any time.
Payment data: purchase history. Card details are processed by Stripe and never stored by Mentz.
Device data: push notification tokens and basic diagnostics.

How we use it

To provide coaching features between you and your Coach (contract).
To process health data for personalised, safe programming (explicit consent).
To process payments and keep financial records (contract, legal obligation).
To send notifications you have enabled (consent; change any time in settings).

Who can see your data

Only your Coach and their authorised team. Every business on Mentz is isolated: other Coaches and clients cannot access your data. We use sub-processors for hosting (Supabase), payments (Stripe) and push delivery (Expo).

Retention

We keep data while your account is active. When you delete your account, coaching and health data is erased immediately; purchase records are retained in anonymised form for statutory accounting periods.

Your rights

You can access and export your data and delete your account from the app (Profile → Privacy) or web dashboard (Settings → Privacy & data). You may also request rectification, restriction or object to processing, and complain to your data protection authority (in the UK, the ICO).
