Terms and Conditions
Version of 6 October 2026.
These terms govern your use of the Cobalt app and service, provided by Stevan Osecanski. By using the service you accept them.
1. Accepting these terms
By creating an account or using the Cobalt app you confirm that you have read these terms, understand them, and agree to be bound by them. If you do not agree, do not use the service.
These terms are read together with the Privacy Policy, available at https://cobaltcoaching.app/privacy.
2. What the service is
Cobalt is software for running fitness coaching. It lets coaches keep a client roster, build workout plans, assign them on a schedule and message their clients. It lets clients see their schedule, log completed workouts — including with no internet connection — and follow their own progress.
Cobalt provides software. Cobalt does not provide personal training, does not choose a coach on your behalf, and is not a party to the relationship between a coach and a client.
3. Who may use the service
You may use the service if you are at least 16 years old and legally able to accept these terms. If you are under 18, you need the consent of a parent or guardian.
You create an account for yourself. Creating an account in someone else's name without their authorisation is not permitted.
4. Your account and credentials
You are responsible for the accuracy of the details you provide when creating an account and for keeping your password safe. Anything done from your account is treated as done by you.
If you believe someone else has accessed your account, change your password immediately and tell us at [email protected].
5. The coach and client relationship
A client is linked to at most one coach at a time. The link is made by an invitation a coach issues and a client accepts; either side can end it.
When the link ends, the data the client entered — workouts, measurements and photos — stays with the client and follows them to their next coach. Private notes a coach kept about a client do not follow the client and are cleared when they link again; see the Privacy Policy for more.
The terms of your working arrangement, any fee, and the content of the training are matters between the coach and the client. Cobalt does not mediate that arrangement and is not responsible for it.
6. Health warning
Cobalt is not a medical device and does not provide medical advice, diagnosis or treatment. Workout plans, calculated values (including estimated one-rep max) and progress charts are informational.
Before starting any exercise programme — and especially if you have a health condition or an injury, are pregnant, or are on medication — consult a doctor. If you feel pain, dizziness, shortness of breath or any other worrying symptom while exercising, stop immediately and seek medical help.
Physical exercise carries a risk of injury. You train at your own risk.
7. Your content
You keep all rights to the content you enter — plans, notes, measurements, photos and messages. We claim no ownership of it.
You give us a limited right to store, process and display that content solely in order to provide the service to you and to the person you are linked with. That right ends when you delete the content or close your account.
8. Acceptable use
While using the service, you must not:
- break the law or infringe anyone's rights, including privacy and copyright;
- send harassing, abusive or threatening content to another user;
- upload photographs of other people without the consent of the person shown;
- attempt to access the accounts, data or content of other users;
- disrupt the service, circumvent limits, or scrape data automatically;
- resell the service or provide it to third parties outside its intended use.
9. Availability
We work to keep the service available and correct, but we provide it "as is", without warranties of any kind. We do not guarantee uninterrupted operation, freedom from errors, or the permanent availability of any particular feature.
We may change, suspend or discontinue the service. We will give you advance notice of material changes and of discontinuation wherever that is reasonably possible.
10. Limitation of liability
To the extent the law allows, we are not liable for lost profits, for data loss arising outside our control, or for indirect or consequential damage arising from your use of, or inability to use, the service.
Nothing in these terms excludes or limits liability that cannot be excluded under applicable law — including liability for damage caused intentionally or by gross negligence, and liability for death or personal injury.
11. Ending your use
You may close your account at any time. What happens to your data is described in the Privacy Policy.
We may restrict or end your access if you seriously or repeatedly breach these terms, if it is necessary to protect other users, or if the law requires it. Wherever possible we will tell you first and give you a chance to put things right.
12. Changes to these terms
We may change these terms. The updated version is published at https://cobaltcoaching.app/terms with a new date, and we will tell you about material changes in the app or by email before they take effect.
If you continue using the service after a change takes effect, you accept it. If you do not accept it, you may close your account.
13. Governing law and jurisdiction
These terms are governed by the law of the Republic of Serbia. Disputes that cannot be settled amicably fall to the competent court in Belgrade.
This does not reduce any rights you have as a consumer under the mandatory law of your country of habitual residence.
14. Contact
The service is provided by Stevan Osecanski, a private individual based in Belgrade, Serbia.
