Metal Stock
Privacy Policy
Effective date: August 30, 2026
Metal Stock is a calculator for estimating the weight, length, quantity, and cost of common metal stock. This policy describes the current release published by Mentalist Apps.
Information we collect
The current release does not collect personal information or require an account. It does not send calculator inputs, saved calculations, preferences, or custom material densities to a developer-managed server.
Information stored on your device
To provide its offline features, Metal Stock stores calculator inputs, saved calculations, preferences, and custom material densities locally on your device. You can delete saved calculations from the app. Deleting the app removes its local data from that device.
Advertising and analytics
The current release does not include third-party advertising or analytics. If a future release adds an advertising or analytics SDK, this policy will be updated before that release is enabled and will explain the relevant data practices and choices.
iCloud and future services
The current release does not require a developer-managed backend. If a future release adds optional Apple services such as private iCloud sync, this policy will be updated to explain what is stored and how that service is used.
Children’s privacy
Metal Stock is a general-purpose utility and is not directed to children. We do not knowingly collect personal information from children.
Changes to this policy
We may update this policy when the app’s functionality or data practices change. The effective date at the top of this page will identify the latest version.
