Where is my data stored?
Your training, range and collection data stays on your iPhone and syncs only to your own private iCloud. It never reaches Caliber.

Lessons, payments & cancellations
Lessons and classes in Caliber Classes are taught by independent instructors, who set their own prices. Caliber doesn't take or hold lesson payments: you pay your instructor directly, the way they list (for example cash, Venmo or Cash App). Caliber doesn't check instructors' credentials — research an instructor before you book.
Cancellations and refunds
Each instructor shows one of three cancellation policies before you send a request, and the policy shown then applies to that lesson. Because you pay the instructor directly, any refund comes from them; Caliber can't make or reverse refunds.
- Flexible: Full refund up to 24 hours before. 50% refund 2–24 hours before. No refund within 2 hours.
- Standard: Full refund up to 48 hours before. 50% refund 12–48 hours before. No refund within 12 hours.

If your instructor cancels a confirmed lesson, they refund what you paid them for it in full.
