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.
