Terms of Use

RallyGrind is a one-time purchase that gives you access to a personalized 6-week off-court tennis training program, delivered through your web browser. No subscription, no recurring charges.

Your purchase grants you a personal, non-transferable license to use the program for your own training. Please don’t redistribute, resell, or copy the program content.

RallyGrind provides general fitness and training guidance only. It is not medical advice and is not a substitute for professional diagnosis, treatment, or coaching. Exercise carries inherent risk. Consult a qualified professional before starting any training program — especially if you have a current injury, pain, or medical condition. You train at your own risk and are responsible for using appropriate equipment, space, and loads.

Your program is tied to the email you provide at checkout and runs entirely in your browser. Clearing your browser data or using “Forget this device” removes local access on that device; your purchase itself is not lost.

We refine session content over time. Improvements ship to all buyers — your program may get better after you buy, never worse.

If something isn’t working or you believe you were charged in error, reach out through the contact details on our About page and we’ll make it right.
