JD Tech & Solutions LLC ("JD Tech & Solutions," "we," "our," or "us") develops mobile applications, calculators, educational tools, and related software.
This Privacy Policy explains how information is handled by JD Tech & Solutions mobile applications, including Machinist Feeds & Speeds and Concrete Volume Calculator.
Our current applications are designed to minimize data collection. Unless specifically stated otherwise below, calculation inputs, saved projects or jobs, and other user-entered information remain on the user's device and are not transmitted to JD Tech & Solutions servers.
Our applications may allow users to enter information needed to perform calculations or save work.
Examples may include:
For the applications covered by this policy, JD Tech & Solutions does not currently collect or transmit this user-entered calculation or machining data to JD Tech & Solutions servers.
This information is processed locally on the user's device unless the user intentionally chooses to export or share it.
Our current calculator applications do not require users to create a JD Tech & Solutions account.
We do not currently require users to provide information such as:
to use the core calculator functionality.
Some applications may allow users to save projects, jobs, preferences, or calculation results locally on their device.
Locally stored information may include:
This information remains on the device unless the user deliberately exports or shares it.
Uninstalling an application or clearing its application data may permanently remove locally stored information.
Machinist Feeds & Speeds is a machining calculator and educational application.
The app may locally process and store information such as:
Machinist Feeds & Speeds may allow users to voluntarily record information about how a machining operation performed.
This information is currently stored locally on the device.
JD Tech & Solutions does not currently operate a cloud service that automatically receives these machining-result records.
Users may choose to export machining information in formats such as CSV or JSON or through other supported sharing/export features.
Export occurs only when initiated by the user.
After information is exported or shared with another application, service, storage provider, or person, its handling may be governed by that third party's privacy practices.
Educational videos contained within Machinist Feeds & Speeds, including lessons related to spindle-speed equations and radial chip thinning, are bundled with the application and are designed to play locally.
Watching these bundled educational videos does not require the app to send viewing information to JD Tech & Solutions or to a third-party video-hosting service.
Concrete Volume Calculator processes project measurements and related calculation information to estimate concrete quantities and related project information.
Calculation information and saved project information are processed locally unless the user intentionally chooses to export or share information using functionality provided by the application or operating system.
Our applications may allow users to create or share files, reports, PDFs, CSV files, JSON files, or other information.
These actions occur only when initiated by the user.
If a user chooses to share information through another application or service—for example:
—the selected third-party service may receive the information being shared.
JD Tech & Solutions does not control how third-party services process information after the user chooses to send information to them.
Our current calculator applications do not use advertising SDKs to serve personalized advertisements.
If advertising is added to an application in the future, this Privacy Policy and the applicable app-store disclosures will be updated before that functionality is released.
JD Tech & Solutions may receive aggregated information made available through application-distribution platforms such as Google Play.
This may include information such as:
This information is provided through the applicable platform and is subject to that platform's privacy practices.
Google Play and the Android operating system may independently process information related to application installation, device operation, security, diagnostics, or store usage. Such processing is controlled by Google and is not the same as JD Tech & Solutions collecting user-entered calculator information.
Our current calculator applications do not require precise geographic location to perform their core functionality.
JD Tech & Solutions does not currently collect precise location information through these applications.
JD Tech & Solutions does not sell personal information or user-entered application data to advertisers or data brokers.
Information stored locally within an application generally remains on the user's device until:
Because locally stored information is not transmitted to JD Tech & Solutions servers, JD Tech & Solutions generally cannot remotely retrieve or delete information stored solely on a user's device.
Users should export any information they wish to preserve before uninstalling an application or clearing its data.
JD Tech & Solutions may in the future offer users the option to voluntarily contribute anonymized or de-identified machining or application-performance data to help improve recommendations, research, or application functionality.
No such future contribution will be enabled silently.
If this functionality is introduced:
At present, Machinist Feeds & Speeds machining-result logging is local-only unless the user deliberately exports the information.
Some JD Tech & Solutions applications may be useful in educational or vocational-training environments.
Our current calculator applications are designed to operate without requiring users to provide personal information to JD Tech & Solutions.
We do not knowingly use these applications to collect personal information from children through JD Tech & Solutions servers.
If you believe personal information has been provided to us improperly, please contact us so that the issue can be reviewed.
We design our applications to minimize unnecessary transmission of user information.
However, no computing device, storage system, application, or electronic transmission method can be guaranteed to be completely secure.
Users are responsible for protecting access to their own devices and any files they choose to export or share.
We may update this Privacy Policy as our applications, services, or data practices change.
When material changes are made, the updated policy will be posted at:

The Effective Date at the top of this page will also be updated.
