Common questions
How do subscriptions work?
The Mac App Store edition will offer the same features for €5 per month or €50 per year. Payment starts immediately, with no free trial. Subscriptions renew automatically unless cancelled. The app shows the price for your country before you confirm. This edition is coming soon.
How do I restore a subscription?
Use Restore purchases on the subscription screen, signed in with the Apple Account used for your purchase. You can also open Subscription from Horizon’s Help menu.
How do I cancel?
Manage your subscription through your Apple Account in the Mac App Store. Cancelling stops future renewal; access remains until the paid period ends. If your subscription expires while you are working, you can finish, save and present that session.
Do I need my own API keys?
Yes. Add your own provider credentials in Horizon’s settings to use AI features. The subscription does not include provider usage: your selected provider may charge separately. Never send your API keys to support.
Where are my presentations saved?
Horizon keeps local working data and versions on your device. Use Save to keep a .horizon file in a folder you choose. Keep a backup of important presentations. If macOS asks you to choose a file again, select it in the file picker to renew access.
What should I include in a support request?
Tell us your Horizon version, macOS version and the steps that led to the problem. A screenshot can help. Remove API keys, passwords and confidential presentation content before sending.
