You get a monthly Readwise Full share slot that includes both Readwise and Reader. Access is via shared login credentials given by the admin once the group is full and the package is activated. Because the account is shared, do not change the password or email, and do not log out other devices so other slots can keep syncing their highlights.
For the single user package, you get immediate full access without waiting for the group to fill. Group packages will follow with a maximum of two people per group, so if you want to split the cost with a friend, stay tuned. The per-slot price is calculated automatically and shown on the package card before payment.
During the active period, your reading positions, highlights, and annotations stay saved in the shared account. Because everyone uses the same account, coordination in the group is highly recommended to avoid overwriting each other's changes. JoinBareng will remind you via WhatsApp before the period ends so renewal can happen on time.
