About.

Trialgrids is a free browser-based toolkit for clinical research coordinators, investigators, and methodologists. It digitizes the small paper tables that still clutter most trial workflows — randomization lists, schedules of assessment, and more on the way.

Privacy. Everything runs locally in your browser. No account, no server, no analytics of your inputs. Your study data never leaves your device. Exported files are downloaded directly from your machine.

Not a medical device. Trialgrids is a documentation aid. It does not handle patient-identifying information and is not intended for primary trial data capture. Always follow your sponsor's data management plan and applicable regulations (GCP, GDPR, HIPAA).
