Privacy Policy

Crucible for macOS · Last updated July 13, 2026

Short version: Crucible collects nothing. It works entirely on your Mac and never talks to the internet.

No data collected

Crucible does not collect, store, or transmit any personal information. There are no user accounts, no sign-in, no analytics, no advertising, and no tracking of any kind.

No network access

The app is distributed with the macOS App Sandbox enabled and without a network entitlement. As a result it is technically incapable of making a network connection. Nothing you type, paste, load, or generate is ever sent off your device.

Your content stays local

• Input you type or paste is processed in memory on your Mac and is never uploaded.
• A file is read only when you explicitly choose it (Input ▸ Load), and it is not copied or transmitted anywhere.
• Output is written to disk or the clipboard only when you choose to save or copy it.
• Saved formulas are stored locally on your Mac.

Third parties

Crucible includes no third-party SDKs, analytics, or advertising libraries. No data is shared with anyone, because none is collected in the first place.

Children

Crucible does not collect data from anyone, including children.

Changes to this policy

If this policy ever changes, the updated version will be posted on this page with a new date above. Since the app collects no data, any changes are expected to be minor.
