How do I cancel my subscription?

Cancelling ends the renewal; your data stays until you actually delete the account. Active DeskOps recurring contracts issue invoices until your access ends, then stop. If you reactivate, their missed invoices are issued once per cycle. Contracts on your own Stripe account keep billing there until you cancel them in Get Paid → Contracts. If you want the data gone as well, that is Settings → Data & privacy on a computer, or Settings → Data & privacy on your phone — and export first.
