Do I need to bind the license to the account?

It depends on where you bought your subscription:
If you bought it on Google Play, binding isn’t required, but we recommend it. Once the license is bound to your AdGuard account, you can use it on other devices.
If you bought it on the AdGuard website, it’s already bound to your account. You’re all set!
If you bought it elsewhere, we recommend binding it too.
An AdGuard account gives you more than license management: you can view which devices your subscription is active on and remove the ones you no longer need.
