FitSync Terms of Use

Last updated: 26 August 2026
Version: 1.0

1. Who these terms are between

These Terms of Use ("Terms") are an agreement between you and Mamba Apps ("we", "us"), covering your use of the FitSync mobile application and the related services at fitsync-api.mambaapps.com (together, the "Service").

By creating an account or using the Service, you accept these Terms. If you do not accept them, do not use the Service.

How we handle your personal data is explained separately in our Privacy Policy.

2. Your licence to use the app

Your licence to install and run the FitSync app is governed by Apple's Standard End User License Agreement. These Terms govern the Service itself and sit alongside that licence. Where the two genuinely conflict on the software licence, Apple's agreement prevails on that point.

Apple is not a party to these Terms and is not responsible for the Service. Apple is, however, a third-party beneficiary of these Terms and may enforce them against you.

3. Eligibility and your account

4. The two roles

Expert — a personal trainer or dietitian who uses FitSync to manage their own clients, publishes service packages, and pays for an in-app subscription.

Member — a client who receives services from an Expert. Members use FitSync free of charge.

5. What FitSync is — and what it is not

This section matters. Please read it.

6. Health warning

FitSync is not a medical device and does not provide medical advice. Nothing in the app — programs, measurements, notes, messages, posts — is a medical diagnosis, treatment, or prescription, and none of it replaces advice from a qualified physician.

7. If you are an Expert

By using FitSync as an Expert, you represent and undertake that:

9. Content and conduct

There is zero tolerance for objectionable content and abusive users on FitSync.

You may not post, send, or upload content that:

Reporting. If you encounter content or behaviour that breaches these rules, report it through the in-app reporting mechanism where available, or write to info@mambaapps.com. We review reports and act on them, and we aim to respond within 24 hours to reports about objectionable content.

What we may do. We may remove content that breaches these rules, and we may suspend or close the account of a user who breaches them — without notice where the breach is serious.

10. Subscriptions and payments

11. Intellectual property

The FitSync app, its design, code, exercise catalogue, and brand belong to us. These Terms give you a personal, non-transferable right to use the Service — nothing more.

Your content stays yours. The programs, posts, photos, and messages you create remain your property. You grant us only the limited licence we need to operate the Service: to store your content, and to show it to the users it is meant for. We do not use your content for advertising, do not sell it, and do not show it to anyone outside the Service.

12. Availability of the Service

We work to keep FitSync running, but we do not guarantee uninterrupted or error-free service. Maintenance, updates, technical faults, or third-party outages may interrupt it.

We may change features, add them, or discontinue them. If a change materially reduces what you get, we will tell you in advance where we reasonably can.

13. Suspension and termination

You may close your account at any time from Settings → Delete My Account. Deletion is explained in the Privacy Policy. Closing your account does not cancel your Apple subscription — cancel that separately through Apple.

We may suspend or close your account if you breach these Terms, if your use harms other users or the Service, or if we are required to by law. Where the breach is not serious, we will give you notice and an opportunity to put it right first.

If we close your account for a breach, you are not entitled to a refund of your subscription. Refund decisions in any case rest with Apple.

14. Limitation of liability

To the extent permitted by law:

None of this limits liability that cannot lawfully be limited — including liability for death or personal injury caused by our negligence, for fraud, or for gross negligence and wilful misconduct. If you are a consumer, the mandatory rights you have under the consumer law of your own country are unaffected by this section.

15. Your responsibility to us

If a third party brings a claim against us because of your breach of these Terms, your unlawful use of the Service, or content you posted, you will cover the resulting loss and reasonable legal costs. This does not apply to the extent the claim results from our own fault.

16. Governing law and jurisdiction

These Terms are governed by Turkish law, and the Istanbul Courts and Enforcement Offices have jurisdiction.

If you are a consumer, this does not deprive you of the protection of mandatory consumer law in your country of residence, nor of your right to bring proceedings before the courts there. Consumers in Türkiye may also apply to the Consumer Arbitration Committees and Consumer Courts.

17. Changes to these Terms

We may update these Terms. We will change the "Last updated" date at the top, and where a change materially affects your rights we will notify you in the app or by email before it takes effect.

If you keep using the Service after a change takes effect, you accept the updated Terms. If you do not accept them, close your account.
