Your clients view through a link, your partners work through an invitation. What each of them can do (view, annotate, download) is set right by right. What you do not grant does not exist for them.
Rights that cascade from the client down to the file, and partners invited without ever exposing what sits around it.
A named link to show a file right away, with no account to create. An email invitation for lasting access, with their own account, to a single file or a whole project. Either way, you set the rights.
Your client views without being able to download, your shop floor measures without being able to approve: each right is granted on its own, on a client, a project, a folder or a single file. Four profiles cover the usual cases; setting rights one by one comes with the Solo plan.
A right set on the project cascades to the folder and then to the file. You only override it where it matters.
Invitations, links, rights, versions, statuses and signatures are written to a log where nothing is erased or rewritten. It reads in plain language and is kept for ten years.
Reader, Annotator, Approver, Full collaborator: four ready-made profiles. From the Solo plan, your own as well.
Name a link to a file, give it an expiry date, close it in one move.
Your partner receives an invitation and comes in with their own account; a free account is enough.
Withdraw an access or close a link at any time: it no longer opens. What has already been downloaded, however, cannot be taken back.
Send a link or invite someone, grant exactly the access they need, keep the record.
