Trust center. Last reviewed 2026-05-19
Marrow is built on verified trust.
Coaches who use Marrow trust us with their members. Members trust their coaches. Both of them trust the rails underneath. This page is where we show our work. The security posture, the sub-processors, the privacy promises, the incident response plan, the data export path, and the security contact. All of it, in one place, written plainly.
We do not claim certifications we do not hold. The honest posture is the moat.
The Marrow promise
One coach cannot see another coach's athletes. Ever. The walls between coaches are enforced at the database, not at the screen. The code path you cannot see is the one that decides who reads what, and we built it so the answer is always the same.
Your data is yours. Coaches can export every athlete on their roster, any time. Athletes can export their full training history, any time. When you leave, you leave with your data, and we delete what we held.
Have a question we did not answer
For privacy and data questions, write to privacy@marrowfitness.com. For security questions, write to security@marrowfitness.com. For everything else, hello@marrowfitness.com reaches us. We answer as soon as we can.
For enterprise buyers and gym partners who need a security questionnaire response, we have a written pack ready to share on request.
Marrow Operating Partners
Whatever your gym needs built, we can build it.
The platform is the system your gym runs on. Operating Partners is the done for you way onto it. We sit with you, find what is slowing the floor down, build the fix in your brand, and keep it running. A branded member app, a booking flow, a growth engine, a piece of your operation no other software will touch. If it helps your gym run better, it is on the table.
You do not have to know what you need yet. Most owners find the next thing once they are running. The moment you hit something you wish your system did, that is the conversation.
