Terms of service · updated 10 November 2026

The terms you use Trainerflow under

These terms apply to trainerflow.com and to the Trainerflow apps for iOS and Android. By creating an account or using the service you agree to them.

Who you are dealing with

The service is operated by Gerasimos Athanasopoulos ("Trainerflow", "we"). You can reach us at support@trainerflow.com.

The service

Trainerflow lets trainers write training programs in a programming environment, assign them to trainees, and follow their progress; and lets athletes and trainees run those programs step by step, on the web or in the mobile app. An AI assistant in the editor can help write and review programs.

Accounts

  • You must be at least 16 to hold an account. Trainers who work with younger athletes are responsible for obtaining a parent's or guardian's consent.
  • While Trainerflow is in early access, accounts are by invitation only. Trainee accounts are created through an invitation from a trainer.
  • Keep your credentials to yourself and tell us if you think someone else has used your account. One account is for one person.
  • Give us accurate information and keep it current.

Your content

Programs, workout data and messages you put into Trainerflow stay yours. You give us the licence we need to store, process, back up and display that content to you and to the people you share it with — a trainer to their trainees, a trainee to their trainer — for as long as your account exists.

You are responsible for what you upload. Trainers are responsible for the programs they assign and for their suitability to the person running them.

Training and your health

Trainerflow is software, not a coach, physician or physiotherapist. Nothing in the service is medical advice. Exercise carries risk; consult a doctor before starting a program, stop if you feel pain or unwell, and use your own judgement about what your body can do on a given day. Programs are written by trainers, who are responsible for their professional advice; Trainerflow does not review them.

The AI assistant

The assistant generates suggestions from a model that can be wrong, incomplete or unsuitable for a given athlete. Review everything it produces before you use it. Assistant usage is metered in credits with caps per plan; we may change how credits are allocated with notice.

Acceptable use

  • Do not use the service for anything unlawful, or to harm, harass or deceive anyone.
  • Do not probe, overload or interfere with the service, scrape it, or try to access accounts or data that are not yours.
  • Do not resell access or share an account.
  • Do not upload content you have no right to upload.

Fees

Trainerflow is free while it is in early access. Paid plans for trainers will be announced at least 30 days before they apply to existing accounts, with prices shown before you subscribe. Payments will be handled by Stripe; prices exclude VAT unless stated. Trainees are never charged for using the app.

Ending things

You can delete your account at any time from your profile page; the effect is described in the privacy policy. We may suspend or close an account that breaks these terms, with notice where that is reasonable. We may also change or discontinue features of the service; if we discontinue it entirely we will give you at least 30 days to export your data.

Warranties and liability

The service is provided as it is, without a guarantee of uninterrupted availability or of fitness for a particular purpose. To the extent the law allows, our liability for any claim connected with the service is limited to the fees you paid us in the twelve months before the claim, and we are not liable for indirect losses such as lost data, revenue or opportunities. Nothing in these terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, or for fraud, and nothing removes rights you have as a consumer under the law where you live.

Governing law

These terms are governed by the law of Greece. If you are a consumer, the mandatory consumer-protection rules of the country you live in continue to apply, and you may bring claims in your local courts.

Changes to these terms

We may update these terms. We will post the new version here with its date and, for changes that matter, email account holders at least 30 days before they take effect. Continuing to use the service after that means you accept the new terms.
