Private by Design
Halidestep 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
Halidestep is a local darkroom notebook and exposure calculator. It does not analyze negatives, control enlargers, assess chemical safety, guarantee archival results, or replace current paper, chemistry, ventilation, electrical, and equipment instructions.
