Try this
- Separate three choices: whether the remaining user wants access, whether the account owner wants to retain the account, and which shared files each person may keep.
- Write an exit checklist for this service: export permitted material, agree on the final shared charge, and let the authorized owner change renewal only after those decisions.
A worked example
“You still use the service and I don’t. Could we agree on whether you want your own account before the next shared charge? Let’s check our saved album separately.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Verify the actual transfer and export options with the service. Do not assume a shared login or subscription can be transferred, and do not erase the collection as a shortcut to ending shared payment.
