Roles, and what each one can do
Owner, admin, member and viewer.
The four
Owner — everything, including billing and closing the account. There is always at least one.
Admin — everything except billing and deleting the company.
Member — makes and edits codes, links, cards, pages and forms; reads reports.
Viewer — reads. Cannot change anything.
Removing somebody
Suspend rather than delete when somebody is leaving temporarily: it keeps what they made and stops them signing in. Deleting a person keeps their work too — a code is the company's, not the person's — but the account cannot be restored.
Deleting signs the person out everywhere at once — the website, the app and any saved fingerprint sign-in — and revokes any API tokens they made. Their codes, links, pages and files pass to the account owner; their digital card stays published but unassigned, so reassign or delete it afterwards. An admin can delete members and other admins; only an owner can delete another owner, and the only owner cannot be deleted at all.
Anybody can also delete their own account, on the website or in the app, under Account → Delete my account. The same rules apply. The only owner closes the whole account under Company settings instead.
