TechAppSuite operates the ISO Fit & Thread mobile application (the "App").
We respect your privacy and are committed to being transparent about how information is handled when you use the App. This Privacy Policy explains what information may be collected, how it is used, and how third-party services integrated into the App may process information.
ISO Fit & Thread allows you to save calculation results to the App's history feature.
This may include:
ISO fit calculations
Thread pitch calculations
Tap drill calculations
Calculation inputs and results
Names or labels that you choose to assign to saved items
This history is stored locally on your device. We do not operate a server that stores or synchronizes your calculation history.
If you uninstall the App or clear its application data, locally stored history may be deleted.
The App uses third-party services provided by Google to display advertisements, understand how the App is used, and identify and resolve technical problems.
These services may automatically collect certain information from your device and your use of the App, depending on the service and your device settings.
Google AdMob
We use Google AdMob to display advertisements in the App.
AdMob and its partners may process information such as:
Advertising identifiers
Device information
IP address
Approximate location derived from network information
App and advertising interaction information
Information used for advertising measurement, fraud prevention, and ad delivery
Depending on applicable settings, consent, and regional requirements, advertisements may be personalized or non-personalized.
You can manage advertising and privacy settings through your Android device and Google account settings.

App instance identifiers
Device and operating system information
Approximate location
App version and related technical information
For example, we may use analytics events to understand which features are used, such as ISO Fits, Thread Pitches, Tap Drills, and Saved History.

Comply with applicable legal requirements
We do not sell your locally stored calculation history or personal information to third parties.
We do not operate our own advertising, analytics, or crash-reporting servers.
However, information may be processed by third-party service providers that are integrated into the App, including:
Google AdMob
Google Analytics for Firebase
Firebase Crashlytics
These providers process information according to their own privacy policies and terms.
Firebase services may process and store data using Google's global infrastructure.
We take reasonable measures to protect information handled by the App.
Your saved calculation history is stored locally within the App's private storage on your Android device and is protected by Android's application sandboxing mechanisms.
Information transmitted to third-party services is handled through their respective security mechanisms.
However, no method of electronic storage or internet transmission can be guaranteed to be completely secure.
ISO Fit & Thread is intended for engineers, machinists, technicians, designers, students, and other users interested in engineering and manufacturing calculations.
The App is not directed specifically toward children.
We do not knowingly collect personal information directly from children.
If you believe that a child has provided personal information through the App, please contact us at techappsuite@gmail.com so that we can review the matter.
You can control certain privacy and advertising preferences through your Android device and Google account settings.
Depending on your location and applicable laws, you may have additional rights regarding the processing of your personal information.
You may also stop the collection of information by uninstalling the App. Information already collected by third-party services may continue to be retained according to their respective policies and retention practices.
The services used by the App are operated by third parties. Their privacy practices are described in their respective policies:
