I bought the subscription in the App Store

If you used your real email address during the purchase, your AdGuard account will be automatically linked to that email address.
If you selected Hide My Email, we can't automatically bind an AdGuard account to your email address. However, we strongly recommend binding your email address to your account manually to avoid losing access to your license key. You can easily do it on this dedicated page.
If you want to change the email address linked to your account, please contact us at support@adguard.com.
