Privacy assay

CruKarat Jewel Privacy

Effective for the CruKarat Jewel iOS app published by CruKarat Jewel (2026). This page describes how the product handles information while you work alloy recipes, melt tickets, and pour estimates at the bench.

CruKarat Jewel does not collect personal data. Alloy math, scrap lots, and melt summaries stay on-device.

On-device processing

Crucible recipe cards, live fineness adjustments, color and workability previews, scrap-to-karat tickets, density pour estimates, and shareable melt summaries are computed locally on your iPhone or iPad. The app is designed to run fully offline after installation.

No accounts or cloud sync

There is no account gate, profile system, or vendor-hosted recipe cloud. You are not required to register or sign in to use the seeded alloy cabinet or any melt tools.

No third-party analytics or advertising

CruKarat Jewel does not integrate third-party analytics SDKs, advertising networks, or tracking pixels. Usage is not measured by external marketing platforms.

Exports you choose

If you export a plain-text or simple PDF melt ticket, the content leaves the app only through the system share sheet you invoke. The app does not upload those files on its own.

Data you may keep locally

Forked recipe cards and metal-part balances
Scrap lot entries and melt-loss assumptions you type
Pour and mold notes saved in on-device storage

These remain under your control on the device; deleting the app removes locally stored app data according to iOS behavior.
