Official support, privacy policy, and marketing information for AlloyTrue Bench Lab on Google Play.
Karat blends, ring sizes & geometry weight — offline metalsmith math at your bench.
AlloyTrue Bench Lab is a dedicated metalsmith calculator built for jewelers, bench workers, and hobby casters who need trustworthy numbers without opening a spreadsheet mid-solder.
From the first karat blend to the final gram on the scale, every tool runs locally on your device. No account required. No cloud dependency. Your formulas, project cards, and metal library stay on your phone — ready after a cold start, even when the shop Wi‑Fi drops out.
Drag portions on the crucible board. Read karat, density, and color family instantly.
Merge scrap lots and hit a target karat before you pour.
Rings, sheet, wire, discs, and bezels — sketch dimensions into grams you can trust.
Convert US ↔ UK ↔ EU ↔ JP sizes and read mandrel diameter in mm or inches.
Plan necklaces, jump rings, and wire wraps with length and weight estimates.
Enter your local g/ozt prices and estimate material cost — fully offline.
15 seeded metals with density and karat reference at your fingertips.
Track planning, in-progress, and ready-to-cut jobs with karat and weight notes.
Designed for real bench workflows. Dense cards, quick-calc chips, mm/in and g/dwt/ozt unit toggles, light & dark themes, a home-screen widget for karat blends and ring-size shortcuts, and optional bench-tip reminders — all wrapped in a forge-inspired palette of burnished gold, patina teal, and charcoal.
Who it is for: bench jewelers, goldsmiths, silversmiths, students in metals programs, and makers who work with karat gold, silver, and carrier alloys daily.
What it is not: AlloyTrue Bench Lab does not buy or sell metals, provide live market feeds, or replace professional assay certification. Always verify critical pours with your own standards.

This Privacy Policy describes how MARKOVETS-YURII ("we", "us", "Developer") handles information in AlloyTrue Bench Lab ("the App"), available on Google Play.
We built AlloyTrue Bench Lab as an offline-first bench tool. We do not operate user accounts, advertising networks, or analytics SDKs inside the App.
Information you provide in the App (stored locally):
This data is saved on your device using local storage (Room database and SharedPreferences). It is not transmitted to our servers because we do not operate backend servers for this App.
Information we do not collect:
The App does not request internet, location, camera, or contacts permissions.
We do not sell, rent, or trade your personal information.
The App does not embed third-party analytics, advertising, or social-login SDKs. Google Play itself may collect device and download information according to Google's Privacy Policy — that relationship is between you and Google.
All App data remains on your device until you clear app storage or uninstall the App. Uninstalling AlloyTrue Bench Lab permanently deletes local databases and preferences.
If you contact us by email for support, we retain your message and our reply only as long as needed to resolve your request.
The App is a general-purpose bench calculator and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has contacted us, email esworthyspeirvk465@gmail.com and we will delete related correspondence.
Local data is protected by standard Android app sandboxing. No method of electronic storage is 100% secure; please use device lock screen and backup practices appropriate for your workshop.
The App processes data locally on your device. If you contact us by email, your message may be processed in jurisdictions where email providers operate.
We may update this Privacy Policy when the App changes. The "Last updated" date at the top will reflect the revision. Continued use after an update means you accept the revised policy.
