Privacy policy

Hezone is a training app for tracking workouts, working with a coach, and training with friends and your gym. This policy explains what we collect, why, who can see it, and how to delete it. We don’t sell your data and we don’t show ads.

What we collect

• Account: your phone number or email, used to send you sign-in codes.
• Profile: display name, username, language and profile photo. During setup we also ask your training goal, experience, training days per week, where you train and your body weight, and optionally your gender, height and birth year. We use these to set up your program, for the men’s and women’s boards, and for strength relative to body weight.
• Training: workouts, sets, weights, reps, programs and progress.
• Coaching: messages with your coach, check-ins (weight, sleep, energy, notes), nutrition targets and progress photos.
• Social: friends, challenges you join, the gym you join, and your coins and the rewards you redeem.
• Payments: if you subscribe on iPhone, Apple handles the payment and sends us a record of the subscription (the plan, its dates and a transaction number) so we can turn Premium on. If you pay on our website, the FIB receipt image and reference you send, and any activation codes you redeem. We never see your bank or card details.
• Technical: if the app crashes, technical details such as device model, system version and the error, so we can fix it.

What we don’t collect

We don’t collect your location, and we don’t track you across other apps or websites. Training-day reminders are scheduled on your phone; nothing about them is sent to us.

Your contacts

Only if you tap “Check my contacts” and allow access. The numbers are turned into one-way codes (hashes) on your phone and only those codes are sent, to find people who chose to be findable by phone. We don’t keep them. Nobody can find you this way unless you turn on “Let people who have my number find me”.

Who can see what

• Your profile and results follow the visibility you choose in the app: everyone, friends, or only you. You can show only your initials instead of your name.
• Your coach sees your workouts, check-ins, nutrition targets and progress photos while you train with them. When coaching ends, so does their access.
• The owner of a gym you join sees your name and the gym board (weekly points), not your workout details. Other members see you in the gym’s list only if you turn that on.
• When you use a reward, the partner shop sees your name (or initials) and which reward you used.
• Our team sees payment receipts to approve Premium, and can see account data to keep the service safe.

AI coach

Only when you use the AI coach, your questions and the training data it needs to answer are sent to Anthropic, which runs the AI model, to write the reply. Anthropic doesn’t use this data to train its models.

Services we use

Supabase hosts our database, sign-in and files on servers in Frankfurt, Germany. Our website runs on a server in Vienna, Austria, and Cloudflare provides its domain and forwards email sent to us. Apple processes App Store purchases. A messaging provider sends sign-in codes by SMS or WhatsApp, and an email provider sends email codes. Anthropic runs the AI coach. A crash-reporting service receives error reports. Each one only gets what it needs to do that job.

How long we keep it

For as long as you have an account. When you delete your account, everything above is deleted straight away, including your files. Copies in our backups are overwritten within 30 days. Apple keeps its own records of App Store purchases under Apple’s privacy policy.

Your choices and rights

• Change your profile, visibility and findability any time under Me in the app.
• Delete your account in the app under Me → Delete account, or on the account deletion page.
• Ask us for a copy of your data, to correct it, or anything else about your privacy: support@hezone.app.

Children

Hezone isn’t meant for children under 13, and we don’t knowingly collect their data.

Changes

If we change this policy, we’ll update the date above and tell you in the app if the change matters.
