Privacy and security

What the system reads, what it excludes by construction, where the data lives, and how to get it back. Written to be attached to a clinic's own privacy review; the companion document formatted for a privacy impact assessment is available on request.

Data handled

Three fields from the clinic's own export: referring clinician, date, and modality. They are aggregated to monthly counts per clinician, and those counts are the entire dataset: a referring clinician's name against how many studies they sent each month.

Data excluded

No patient field is read, stored, or transmitted. A long-format billing export is aggregated to monthly counts at the moment of upload, before anything is stored, so patient-level rows do not reach the system even in transit through it. There is no patient table, no field for patient data, and no place to put one; the exclusion is enforced by the schema itself.

Storage and residency

Each clinic runs its own deployment; nothing is pooled across clinics, and no clinic is benchmarked against another. The infrastructure is in the United States. What crosses the border is the monthly counts described above.

Access control

The dashboard is closed until a password is presented; passwords are verified server-side and never shipped inside the application code. Sessions carry a signed, short-lived token. Time-limited access codes can be issued and revoked individually. The vendor can see what the clinic can see, which is monthly counts.

Retention and return

The dataset is a small set of monthly count files, exportable by the clinic from inside the product at any time ("Your data", on the Data Update page: the complete referral history and the team's contact log, as CSV). On termination the same export is the handover, and deletion on request is the export in reverse: the deployment, its version history, and the call list are removed. Contractual timelines are in the services agreement.

Page counting

The marketing site uses cookie-less, first-party page counting. The demo records sign-in times. No third-party trackers, no advertising pixels, no cookies.
