How Grams Left Handles Your Data

A plain-English overview of what we collect, where it goes, and what we never share. Because you deserve to know exactly what happens to your tracking data.

Our promise: We do not sell, share, or broker your cannabis, prescription, strain, or consumption data to anyone — not clinics, pharmacies, advertisers, insurers, employers, or data brokers. Ever.

Where Your Data Goes

A simple look at what data Grams Left collects, where it is stored, which processors handle specific functions, and — crucially — what is not disclosed outside the service.
