Signalment is electronic data capture software for veterinary clinical and observational studies in client-owned animals. It brings protocol and consent versioning, case report forms, owner eDiaries with eConsent, randomization and blinding, scanned record intake, monitor queries, electronic signatures, and a hash-chained audit trail into one workspace. Study teams can lock a database with a fingerprint and export CSV files, a data dictionary, and a JSON bundle. It is designed for pet-health sponsors, specialty practices, university trial offices, and veterinary CROs. Plans include a free Pilot tier, with paid workspace plans available.
