Effective Date: August 28, 2026
This Privacy Policy applies to the Classic Calculator mobile application (the "Application"), developed and operated by Studio Epsilon 101 (the "Service Provider").
By downloading, installing, or using the Application, you acknowledge that you have read and understood this Privacy Policy.
The Application is designed to perform calculator functions primarily on your device.
The Application does not require you to create an account or provide personal information such as your name, email address, phone number, or postal address.
The calculator functions and calculations are performed locally on your device. The Service Provider does not receive or have access to the calculations you enter into the Application.
However, the Application uses Google Mobile Ads (AdMob) to display advertisements. As a third-party advertising service, Google Mobile Ads may collect and process certain information from the device and the Application for purposes such as delivering, measuring, and improving advertisements, as well as preventing fraud and abuse. The information handled by Google may include device or advertising identifiers, information about the device and application, approximate location information, and information relating to interactions with advertisements, depending on the user's device, settings, consent choices, and applicable services.
The Service Provider does not directly access or control information collected by Google Mobile Ads through its own systems.
The Application uses the following permissions:
Internet — required to load advertisements and to access online resources such as the Privacy Policy.
Access Network State — used to determine network connectivity and support advertisement loading.
The Application does not request access to:
Contacts
Camera
Microphone
Device location through Android location permissions
SMS
Call Logs
Photos, Videos, or Audio
Files and Storage
The Application uses Google Mobile Ads (AdMob), a third-party advertising service provided by Google.
Google Mobile Ads may process information such as advertising or device identifiers, device information, application information, approximate location, and information related to advertising interactions for purposes including advertising delivery, measurement, fraud prevention, and security, subject to Google's policies and the user's privacy settings and consent choices.
For more information about how Google handles data when its services are used, please review Google's Privacy Policy:

The Application displays advertisements provided through Google Mobile Ads (AdMob).
Advertising may be personalized or non-personalized depending on applicable laws, the user's consent choices, device settings, and Google's advertising controls.
Users in certain regions may be presented with consent choices relating to personalized advertising and the processing of information for advertising purposes. Google's advertising and privacy practices are governed by Google's own policies and controls.
The Application itself does not use website cookies.
Third-party advertising technology, including Google Mobile Ads, may use device identifiers and similar technologies to provide, measure, and protect advertising services.
The Service Provider does not sell or rent users' personal information.
Because the Application uses Google Mobile Ads, information may be transmitted to or processed by Google and its advertising partners as necessary to provide advertising-related services, measurement, security, fraud prevention, and other applicable purposes. The precise data processing may depend on the user's device, settings, consent choices, and the services available in the user's region.
The Service Provider may disclose information when required by applicable law or a valid legal obligation.
The Service Provider does not maintain a user account or a database containing users' calculator calculations.
Data handled by Google Mobile Ads is subject to Google's own retention practices and policies. The Service Provider does not control Google's retention periods. Please refer to Google's Privacy Policy and relevant Google advertising documentation for more information.
If you contact the Service Provider by email, the information you voluntarily provide may be retained for as long as reasonably necessary to respond to your inquiry or to comply with applicable legal obligations.
Depending on your country or region, you may have rights regarding personal data and the use of advertising technologies.
Where required by applicable law, users may be provided with choices regarding personalized advertising and certain data processing activities.
You may also manage certain advertising and privacy settings through your device and Google account settings, where applicable.
For questions regarding privacy or the Application, you may contact the Service Provider using the contact information below.
The Application is intended for a general audience and is not specifically directed to children.
The Application does not knowingly request personal information directly from children.
Because the Application uses third-party advertising services, advertising and data-processing practices may vary depending on the user's age, region, consent status, and applicable Google policies. Where child-directed treatment or other special requirements apply, the relevant Google policies and applicable laws will govern the processing of advertising-related information.
The Service Provider takes reasonable measures to protect information under its control.
The Application itself performs calculator functions locally and does not maintain a user account database.
Information processed by Google Mobile Ads is subject to Google's security and privacy practices.
No software or electronic system can guarantee absolute security under all circumstances.
Because the Application uses Google Mobile Ads, information processed for advertising and related services may be handled by Google or its service providers in countries other than the user's country, subject to applicable laws and Google's privacy practices.
For more information, please review Google's Privacy Policy:

This Privacy Policy may be updated from time to time to reflect changes to the Application, advertising services, or applicable legal requirements.
Any changes become effective upon publication of the updated Privacy Policy.
