Questions

How do I install an app?
Open the app and use your browser's Install option (Chrome or Edge), or Share → Add to Home Screen on iPhone and iPad. It then opens in its own window and works offline.
How does the licence work?
Every app runs fully for 7 days. After you buy, Gumroad emails a licence key; paste it into Activate in the app. One key works on up to 3 of your devices.
Where is my data stored?
Only on your device, in the browser's storage for that app. Nothing is uploaded. Use Export in the app to keep a backup or move to another device.
What happens if I'm offline?
The apps work offline after the first visit. The licence is checked once when you activate and occasionally in the background; an outage never locks a paying customer out.
Can I get a refund?
Yes. Purchases are handled by Gumroad and come with a 30-day money-back guarantee. A refunded key stops working.
Is there a subscription?
No. Each app is a one-time purchase. Updates to the same app are included.
