Common questions

The capture shortcut does nothing on my Mac. Stemulus needs Screen Recording permission to capture part of your screen, and it asks the first time you capture. If you declined, allow Stemulus in System Settings, Privacy & Security, Screen & System Audio Recording. The shortcut only works while Stemulus is running, and if another app already uses it, pick a different one in Capture Settings. Capture Problem is always available from the menu too. You can still paste, choose or drag in an image, or type the problem.

I bought something but it is not showing. On the Stemulus Pro purchase screen, choose Restore. It checks your App Store purchases and updates your balance.

How do I cancel Stemulus Pro? Subscriptions are managed by Apple. In Stemulus, open your account and choose Manage Apple Subscription, or go to your App Store account settings. Deleting your Stemulus account does not cancel an Apple subscription.

How do I delete my account? Open your account in Stemulus and choose Delete Account. This permanently removes your account, and your assignments, saved problems and study material on that device. Server cleanup may take a few minutes.

Do my problems sync between my Mac and iPhone? Not yet. Your assignments, saved problems, guides and practice sets are stored on the device where you made them. Link an Apple or Google account when you want to use your access on other platforms.
