# Can I use Knowunity on more than one device or with more than one account?

> You can sign in to your account on several devices. Pro belongs to the account that bought it, two accounts cannot be merged, and deleting an account is permanent.

Short answers to the questions about devices and accounts that come up most.

## One account on several devices

Sign in with the same method on each device, for example Google, Apple or your email. Your uploads, streak and plan belong to the account, so you see them on every device you sign in on.

To sign out of the devices you no longer use, see *Someone else may be using my account*.

## Pro belongs to one account

Pro is tied to the account that was signed in when you bought it. Another account on the same phone does not get it. If Pro is missing on a new device, sign in to the account that bought it and tap **Restore Subscription** in **Settings**. See *I paid for Pro but it is not active*.

To move Pro to another account, or to share it, see *Can I share my subscription or move it to another account?*

## More than one account

Two accounts cannot be merged. Keep the one with your plan and delete the other. See *I have two accounts. Which one should I keep?*

Deleting an account is permanent, and support cannot restore it. Cancel any subscription first. See *How do I delete my account?*

## A phone with parental controls

If a child's phone blocks the purchase, see *Buying Pro for my child when the store blocks the purchase*.
