Terms of Service

Last updated: 14 July 2026

These terms govern use of the Strong OS platform and website (strong-os.com). By creating an account or using the service you agree to them. If you’re using Strong OS as a member of a studio, your relationship for classes, payments and refunds is with your studio; these terms cover your use of the software.

The service

Strong OS provides studio-management software: scheduling, online booking, memberships and class packs, payments, member apps and related tools. We work hard to keep the service fast and available, and we may improve or change features over time.

Accounts

You’re responsible for your login credentials and for the accuracy of the information on your account. Studio owners are responsible for how their staff use the platform and for having the right to upload their member data.

Fees

Subscription fees, any per-transaction fees and the length of your term are set out in your order or agreement with us. Fees for members’ class purchases are set by, and paid to, the studio.

We may increase our subscription fees once a year in line with inflation. Where we do, we’ll tell you before the increase takes effect, and you’re free to cancel in the normal way if you’d rather not continue. Any other change to your fees will be agreed with you.

Publicity and feedback

While you’re a customer, we may refer to you as one — using your studio’s name and logo on our website and in our marketing — and you may ask us to stop at any time. Being featured doesn’t entitle you to any payment, discount or other benefit.

If you send us feedback, feature requests or suggestions, we’re free to use them without restriction or payment, and anything we build as a result belongs to us. Nothing in this section gives you any rights in the Strong OS software or brand, and nothing in it affects your ownership of your own data.

Acceptable use

  • No unlawful use, and no uploading content you don’t have the right to use.
  • No attempting to breach, probe or overload the service or access others’ data.
  • No reselling or white-labelling the service except as agreed with us in writing.

Your data

Your studio’s data — members, schedules, bookings — is yours. You can export it at any time, and our Privacy Policy explains how we handle personal data. We never sell your member list or market it to other studios.

Availability & support

We aim for high availability but the service is provided “as is” and no software is guaranteed uninterrupted. We back up data regularly and provide support by email.

Liability

Nothing in these terms limits liability that cannot be limited by law. Otherwise, our total liability arising out of the service in any 12-month period is limited to the fees you paid us in that period, and we are not liable for indirect or consequential losses such as lost profits.

Ending the agreement

Termination and any notice periods are set out in your order or agreement. On termination we’ll make your data available for export for a reasonable period, then delete it in line with our Privacy Policy. We may suspend or terminate accounts that breach these terms.

General

These terms are governed by the laws of England and Wales, with the courts of England and Wales having exclusive jurisdiction. If we make material changes we’ll update this page and tell account holders. Questions: hello@strong-os.com.
