Terms of Service

Last updated: 31 October 2026

These terms apply to Muscle Train at muscletrain.app. By creating an account or using the service you accept them.

The service

Muscle Train generates training programs and lets you track your workouts. The project is in active development: features may change, break or disappear. The service is provided free of charge, “as is”, without warranties of any kind.

Health disclaimer — please read

Muscle Train is not a medical service and does not provide medical advice. Programs and exercise suggestions are produced automatically from the data you enter and from a general exercise database — they are not reviewed for you personally by a doctor or a certified trainer.

Consult a physician before starting or changing a training programme, especially if you have any medical condition or injury, or are pregnant.
Learn correct technique and choose sensible loads. Stop immediately if you feel pain, dizziness or discomfort.
You train at your own risk. We are not liable for injury, health damage or other harm resulting from use of the service.

Your account

You must be at least 16 years old to use Muscle Train. The service is not intended for children, and training weights are derived from adult strength standards.
Provide accurate information — program generation relies on it.
Keep your password safe; you are responsible for activity under your account.
One account per person; do not impersonate anyone.
We may suspend accounts that abuse the service.

Acceptable use

Do not:

attack, overload or disrupt the service;
attempt unauthorised access to other users’ data or to our systems;
bulk-scrape the exercise database;
send spam through the feedback form;
upload unlawful, offensive or infringing content.

What you share with others

Other people see your username and avatar, your feed posts, the programs you share and the places you add to the map. Do not post, or use as a name, anything that:

harasses, threatens or bullies anyone;
promotes hatred of, or discrimination against, people for who they are;
is sexually explicit, or shows or encourages violence or self-harm;
impersonates another person or misleads others about who you are;
reveals someone else’s personal information;
is spam, advertising or a link to unrelated sites;
is unlawful or infringes someone else’s rights.

If you see something like this, report it from the ⋯ menu next to it, or from the place’s window on the map. In the same menu you can also hide a person’s posts and programs from yourself.

We review reports and remove what breaks these rules: we may hide a post, stop sharing a program, remove a place or an avatar, and suspend accounts that break them repeatedly.

Your content

You keep ownership of what you enter — training data, feedback and screenshots. You give us permission to store and process it for the purpose of running the service. You confirm you have the right to upload anything you attach.

Exercise suggestions

You can suggest an exercise for the library. Describe it in your own words: do not copy text, tips, pictures or videos from other websites, apps, books or courses, whether free or paid. By sending a suggestion you confirm that you wrote it yourself, and you allow us, free of charge, to use, edit and translate its text to add the exercise to the library. We decide whether to add the exercise and in what form; the library does not name the author of a suggestion.

Availability and liability

We do not guarantee uninterrupted operation, and we cannot guarantee that data will never be lost — please export anything important (CSV export on the Progress page). To the extent permitted by law, we are not liable for indirect damages or for lost data arising from use of the service.

Termination

You may stop using the service and request deletion of your account at any time by writing to [email protected]. We may discontinue the service, or your access to it, if these terms are broken.

Changes to these terms

We may update these terms; the date above will change accordingly. Continuing to use the service means you accept the current version.
