FitterCalc collects nothing. The app has no accounts, no analytics, no ads, no tracking, and makes no network connections. Every calculation, saved job, and setting stays on your device and never leaves it. If you delete the app, that data is gone. Purchases are processed entirely by Apple or Google; we never see your payment information.
Because we collect no data, there is nothing for us to share, sell, or lose. If this policy ever changes, this page will say so first.
FitterCalc's formulas are verified against published handbook and ASME standard values, and every calculation can show its work. Even so: verify critical measurements independently before cutting. FitterCalc is provided as-is, without warranty of any kind.
