Speeds & Feeds Machinist Calc: Privacy Policy

Effective 27 September 2026. Published at https://apps.digitalshijil.com/machinist/privacy/

Speeds & Feeds Machinist Calc is published by DIGITAL SHIJIL LLC ("we"). This policy explains what the app does with information. The short version: what you type stays on your phone. There are no accounts, no ads and no analytics, and the app's own code never connects to the internet.

What you enter stays on your device

Tool sizes, cuts, the materials you edit or add, the tools you save, your saved setups and your settings are stored only in the app's private storage on your phone. We do not receive them, and we have no server that could.

• There is no sign-in and no account.
• There is no advertising and no advertising ID.
• There is no analytics or crash-reporting library. We see only the anonymous crash and performance statistics that Google Play shows every developer (Android vitals).
• The app requests no permission of its own: no camera, no location, no contacts, no storage permission. Setup sheets and exports leave the app only through the system share sheet or file picker, and only when you choose.

Google Play Billing

The optional Pro unlock is sold through Google Play. Google processes the payment; we never see your card or payment details. Google's Play Billing library, which the app must include to sell Pro, sends Google its own diagnostic information about billing (for example, whether a connection to Google Play succeeded). For the Data safety section this is declared as:

App info and performance > Diagnostics: collected, not shared, required

That information goes to Google under the Google Privacy Policy (https://policies.google.com/privacy), not to us, and we cannot see or delete it. To support this library the app's installed package carries the INTERNET and ACCESS_NETWORK_STATE permissions, added by Google's billing library; nothing you type is sent.

Backups and your own copies

If you use Android's own backup or phone-to-phone transfer, your materials, tools, setups and settings are included in that backup, which is held by Google under your Google account settings. Setup sheet PDFs and "Export all my data" files go only where you send them.

Your control

• Settings > Export all my data saves everything as one JSON file you choose where to keep.
• Settings > Delete all data erases your edited materials, saved tools, saved setups and settings from the phone. Uninstalling the app does the same.

Children

The app is a machining tool for adults and is not directed at children. It collects no personal information from anyone.

Changes

If the app ever changes what it does with information, this page and the Play listing will say so before the change ships.
