You can check the compatibility score with your theme when you are using Login to see price (Platinum plan, $25/mon) and Passcode to view price (Premium plan, $50/mon).
Check the compatibility score between the app and the theme: Go to the app > Install >> Check theme compatibility now
With other rule types, unfortunately, we do not provide any tools to check theme compatibility. However, please be ensured that our app works perfectly with every free theme from Shopify.
