None of what you upload is used to train anyone's AI. It is encrypted on the way and while it sits there, and one account's data is never mixed with another's.
The tab holds your Data Processing Agreement, a Usage analytics switch you can turn off to stop being counted, Download My Data (a full export), and Delete My Account.
Your tenants' details are yours to look after — we only hold them for you. You need a reason to hold them, and running the tenancy is one.
They are entitled to be told you hold their details, to see them, and to ask for them to be corrected.
