Onbrief stores what your agency and your clients put into it: workspace and client space names, the updates you publish, the files you upload, the approvals you raise and the answers to them, and the activity log that records all of the above.
For people, we store a name, an email address, a role, and the record of what that person did inside the workspace. We do not ask for a postal address, a phone number or a date of birth, and there is nowhere to enter one.
For billing we store the workspace's plan, its seat count, its invoice history and the last four digits of the card. The card number itself is never stored by Onbrief — it is held by our payment processor, and we hold a reference to it rather than the number.
We do not sell any of this, and we do not use the contents of a workspace to train anything.
