By default, your documents stay private to your account — only people you've explicitly invited can see them. There is no public listing and no cross-account visibility.
What other users in your account can see depends on the role you assigned them when you sent the invite:
- Contributors can only see and manage the documents they themselves uploaded.
- Members, Admins, the account Owner, and Accountants have full access to every document in the account.
So if you want a teammate to upload receipts but not browse anyone else's, invite them as a Contributor. If you want your bookkeeper or accountant to see everything, invite them as an Accountant (which also doesn't use a paid seat).
For more on what each role can do, see Understanding access levels and user roles, and to change someone's role later, see Changing access levels for users.
One thing to keep in mind
If you generate a shareable link for a monthly document collection, anyone who has that link can view and download the documents in that collection without a SparkReceipt account. The link is time-limited, but it's a deliberate exception to the "private by default" rule — only share it with people you trust.
