FAQ
What does the £6.00 buy?
A one-off unlock, no subscription: unlimited workouts, progress charts, CSV import and your full history. The free try is 3 workouts with everything open. Export to CSV is always free.
Where is my data kept?
Only in this browser on this device. Your sets are never uploaded. The only things that leave the browser are a page-view count and, if you pay, the payment check with Stripe through our own server.
Which browsers work?
Current Chrome, Safari, Firefox and Edge on phone or computer. After the first visit it works offline. Clearing site data deletes your log, so export a CSV now and then.
Can I get a refund?
Access starts straight away, so the 14-day cancellation right ends once you use it. If something is broken, email business@thatched.ai and we will sort it out.
