Privacy Policy · Last updated July 23, 2026
Construction Calculator does not collect any data. Everything you enter stays on your device.
Nothing. The app has no account, no sign-in, and no servers. Your dimensions, saved calculations, and projects are stored only on your device using Apple's on-device database. We never see them.
The app does not send your data anywhere. There is no analytics, no advertising, and no third-party SDK that receives your information. It works fully offline.
When you export a project's material list as PDF or CSV, the file is created on your device and shared only where you choose to send it (email, Files, AirDrop, and so on). We are not involved in that transfer.
Quantities are estimates based on public engineering constants and standard waste allowances. Always verify against local codes and your supplier before ordering. The app is not a substitute for professional judgment.
The app is rated 4+ and collects no personal information from anyone, including children.
If this policy changes, the updated date above will change. Material changes will be reflected in an app update.
