Yes. Even while you are on the "Monthly" or "Annual" plan, you can purchase the "Lifetime" plan from the Premium Service screen in the app.
However, purchasing the Lifetime plan does not automatically stop your current subscription (Monthly/Annual). To avoid being charged further, please cancel the subscription yourself.
1. What happens to the subscription
A subscription keeps renewing automatically until you cancel it yourself. So whether you
- purchase the Lifetime plan while on the Monthly plan, or
- purchase the Lifetime plan while on the Annual plan,
you may be charged for both the subscription and the Lifetime plan unless you cancel. After switching to the Lifetime plan, please don't forget to cancel the subscription.
■ How to cancel a subscription (automatic renewal)
- On your Android device, go to subscriptions in Google Play (you can also get there from the menu (≡) → "Premium Service" → "Subscription Status" in this app)
- Select the subscription you want to cancel (Simple Notes)
- Tap "Cancel subscription"
* Menu names and locations may differ slightly if Google Play changes its design.
2. Remaining subscription period and refunds
If you purchase the Lifetime plan partway through a plan, we do not refund the difference for the remaining period of the Annual or Monthly plan, however much time is left. This follows the way Google Play works and its policies. Thank you for your understanding.
We apologize for the inconvenience and appreciate your understanding.
