Private by Design
Gaugefolio 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
Gaugefolio is a local asset and evidence organizer. It does not perform or certify calibration, calculate measurement uncertainty budgets, determine conformity for regulated use, lock out equipment, or replace approved quality systems, accredited laboratories, standards, and qualified metrology personnel.
