Receipt without access
A coat-check stub.
Submitters can keep a receipt URL showing aggregate arrival facts and status. It does not list, retrieve, edit, or delete files.
ReceiptsFor professionals
A controlled intake channel, not a portal.
Clients, sources, employees, candidates, researchers, or patients can submit files without accounts. They get proof of arrival, but not a shared folder, message thread, or file-return path.
Professional fit
Useful when the sender should not become a user.
- Lawyers receiving privileged client documents.
- Journalists collecting source material.
- HR and compliance teams running intake channels.
- Medical, research, and support teams collecting sensitive records.
What professionals get
Arrival proof and handling context without collaboration features.
Submission groups
Files that arrived together stay together.
Files selected or dropped as one batch share an immutable submission envelope, so the admin can see package context later.
EnvelopesHandling record
Manifest and sealed mode.
Admins can export object hashes and handling events, then seal a page after intake closes so later actions are visible as post-seal handling.
ManifestsBoundary
Sprag stops at intake.
Sprag does not manage cases, run investigations, review documents, or certify legal admissibility. It receives files in a controlled way and preserves useful intake facts for the systems and professionals that handle the work afterward.
