Private by Design
Gritorbit has no account, ads, tracking, analytics, subscription, or developer-operated backend. Records stay on your device unless you intentionally export a PDF through the iOS share sheet.
Product Boundary
Gritorbit is a recordkeeping and arithmetic tool. It does not identify minerals, certify material compatibility, operate a tumbler, prescribe exposure controls, or replace equipment, material, dust, wastewater, and local disposal guidance.
