The AdGuard Personal 1 year group plan covers activation on up to 3 devices per user. After your QRIS payment is received, JoinBareng admin will send the shared account credentials. Use those credentials to log in on your device, and sync will run automatically once the account is active.
Because this is a shared account, a few important rules apply: do not change the registered password or email, do not log out other members' devices, and use AdGuard reasonably. Violating these rules may force admin to reset the account, which will cut access for everyone. Group plans are limited to 4 members, and right now only the 1-user plan is open while group plans are coming soon.
If a group plan is not yet full, you can still order the 1-user plan and get access right after payment. Once group plans are open, JoinBareng will enable that option and you can switch to a group slot anytime. All communication and confirmation happen via the WhatsApp number you register at checkout.
