Dimly Plus is an auto-renewing subscription, offered yearly (with a free trial for eligible accounts) and weekly.
Payment is charged to your Apple Account when you confirm, or when the free trial ends.
The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the period.
Manage or cancel it in Settings › Apple Account › Subscriptions. Any unused part of a free trial is forfeited when you buy a subscription.
How Dimly works
Dimly relies on Apple's Screen Time. Blocking depends on iOS and may be affected by other apps or profiles that manage Screen Time on your device. Dimly is a tool to help you focus; it is not a medical or parental-control product.
