Privacy Policy for Miniature Pendulum Sandbox

Last updated: August 23, 2026

This Privacy Policy explains how information is handled when you install, access, or use the Miniature Pendulum Sandbox browser extension.

Miniature Pendulum Sandbox is a compact physics simulation extension that runs within a browser toolbar popup. It allows users to adjust pendulum length and mass, swing the pendulum, and observe how it interacts with and knocks over stacked shapes.

The extension is designed as a local interactive sandbox. Its core physics simulation, collision calculations, object movement, and visual rendering take place within the browser environment.

1. Scope of This Privacy Policy

This Privacy Policy applies specifically to the Miniature Pendulum Sandbox browser extension and the functionality provided directly through the extension.

It does not govern unrelated websites, browser vendors, operating systems, browser extension marketplaces, or other third-party services that users may access independently.

2. Core Purpose of Miniature Pendulum Sandbox

The single purpose of Miniature Pendulum Sandbox is to provide an interactive physics sandbox within a browser toolbar popup.

Users can modify pendulum characteristics and observe the resulting motion, collisions, and movement of stacked objects.

The extension is intended for casual experimentation, visualization, learning, and entertainment.

3. Information We Require

Miniature Pendulum Sandbox does not require personally identifiable information for its standard functionality.

Users are not required to provide:

• Full name;
• Email address;
• Phone number;
• Postal address;
• Government identification information;
• Payment card information;
• Bank account information;
• Passwords;
• Authentication credentials; or
• Other unrelated personal information.

4. No Account Required

Miniature Pendulum Sandbox does not require users to create a dedicated account to use its core physics simulation.

Users do not need to register a username, password, email address, or profile simply to open the sandbox and interact with the pendulum.

5. Toolbar Popup Operation

Miniature Pendulum Sandbox is designed to operate through a compact toolbar popup provided by the browser extension interface.

Opening the extension displays the physics sandbox without requiring the user to navigate away from the webpage currently open in the browser.

The simulation interface, controls, objects, and visual effects are contained within the extension's own popup environment.

6. Physics Simulation

Miniature Pendulum Sandbox processes numerical and graphical information required to simulate the movement of the pendulum and surrounding objects.

Simulation data may include:

• Pendulum length;
• Pendulum mass;
• Pendulum angle;
• Pendulum velocity;
• Object positions;
• Object rotation;
• Collision states;
• Movement states;
• Simulation timing; and
• Other values required for physics calculations.

7. Pendulum Length

Users may adjust the length of the pendulum in order to experiment with different movement and collision behavior.

The selected length is treated as a physics simulation parameter and is used solely to calculate the movement of the pendulum.

Pendulum length is not personally identifiable information.

8. Pendulum Mass

Users may also adjust the mass assigned to the simulated pendulum.

The mass value may influence motion, impact behavior, or interaction with stacked shapes according to the simulation's physics model.

This value is used only to provide the requested sandbox functionality.

9. Stacked Shapes

Miniature Pendulum Sandbox includes simulated shapes that may be arranged or stacked within the sandbox.

When the pendulum swings into these shapes, the extension calculates movement and collision behavior and updates the visual scene accordingly.

Shape information is part of the local simulation state and is not personal information about the user.

10. Collision Calculations

The extension performs collision calculations to determine how simulated objects interact with each other.

These calculations may consider information such as object position, movement, mass, contact points, angle, or other physics parameters.

Collision calculations are used only to generate the visual behavior of the sandbox.

11. Local Processing

Local processing may include:

• Calculating pendulum motion;
• Calculating collisions;
• Updating object positions;
• Updating object rotations;
• Rendering the simulation;
• Responding to user controls;
• Resetting the scene; and
• Maintaining temporary simulation state.

This approach allows the extension to provide its core functionality without requiring a remote personal account.

12. Temporary Simulation State

While the sandbox is running, the extension may temporarily maintain the values needed to calculate and display the current scene.

Temporary state may include pendulum parameters, object positions, collision information, animation state, and other values required to continue the simulation.

These values are functional data associated with the simulation rather than information intended to identify individual users.

13. Browser Storage

Depending on the implementation, Miniature Pendulum Sandbox may use browser-provided local storage to remember functional preferences or sandbox settings.

Locally stored information, if used, could include values such as:

• Preferred pendulum length;
• Preferred pendulum mass;
• Interface settings;
• Simulation preferences; or
• Other non-sensitive configuration values.

Such storage is intended solely to support extension functionality and is not intended for advertising profiling or cross-site tracking.

14. Website Content

Miniature Pendulum Sandbox does not require the general content of webpages visited by users in order to provide its core simulation.

Webpage text, images, videos, forms, documents, and other site content are unrelated to the ordinary operation of the physics sandbox.

The extension is not designed to archive, index, or analyze unrelated webpage content.

15. Browsing History

Miniature Pendulum Sandbox does not require a user's browsing history in order to simulate pendulum movement or object collisions.

The extension is not designed to maintain a historical record of websites visited by users.

Browsing history does not need to influence pendulum length, mass, collision behavior, or object movement.

16. Search History

Miniature Pendulum Sandbox does not require users' web search history for its physics functionality.

Search queries entered into unrelated websites are not necessary for operating the simulation.

17. Website Form Data

Visual elements in the sandbox are generated as part of the extension interface rather than captured from a camera.

26. Microphone Access

Miniature Pendulum Sandbox does not require microphone access to simulate pendulum movement or collisions.

The extension is not designed to record conversations, ambient sounds, or voice input as part of its standard functionality.

27. Device Files

Miniature Pendulum Sandbox does not require access to unrelated personal files stored on a user's device in order to provide its core simulation.

28. Browser Permissions

Miniature Pendulum Sandbox is intended to use only browser capabilities reasonably necessary for its disclosed functionality.

Its standard physics sandbox operates from the extension's toolbar popup and does not require general access to every webpage merely to perform pendulum calculations.

Browser permissions are not intended to be used for unrelated surveillance, data brokerage, advertising profiling, or cross-site tracking.

29. No Continuous Background Monitoring

Miniature Pendulum Sandbox does not need to continuously monitor browsing activity in order to provide its physics simulation.

The extension operates when the user opens and interacts with its own toolbar popup.

30. Advertising

Miniature Pendulum Sandbox does not use pendulum settings, simulation actions, or collision behavior to create targeted advertising profiles.

The extension is not designed to monitor users across unrelated websites for behavioral advertising or remarketing.

31. Sale of Personal Information

Miniature Pendulum Sandbox does not sell personal information to advertisers, marketing organizations, data brokers, or other third parties.

The purpose of the extension is to provide an interactive physics sandbox, not to monetize information about users.

32. Data Brokerage

Miniature Pendulum Sandbox does not operate as a data broker.

Simulation settings and interactions are not intended to be compiled into commercial datasets for sale or resale.

33. User Profiling

Miniature Pendulum Sandbox does not use pendulum settings or simulation behavior to build behavioral or demographic profiles.

Choices such as pendulum length, mass, or repeated simulation actions are not intended to be analyzed to infer personal characteristics.

34. Cross-Site Tracking

Simulation parameters are not intended to be combined with unrelated browsing information for behavioral advertising or user profiling.

If future versions introduce diagnostic or aggregate usage measurement, this Privacy Policy may be updated where appropriate to describe those practices.

37. Data Minimization

Miniature Pendulum Sandbox follows the principle that a browser extension should process only information reasonably necessary for its disclosed functionality.

Since the extension's purpose is to provide a small physics sandbox, unrelated personal information and browsing data are not necessary for ordinary use.

38. Purpose Limitation

Information processed by Miniature Pendulum Sandbox is intended to be used only to provide, maintain, improve, or secure the extension's disclosed physics functionality.

Simulation information is not intended to be repurposed for advertising, credit scoring, employment screening, insurance decisions, or unrelated commercial surveillance.

39. Data Retention

Miniature Pendulum Sandbox is not designed to maintain a permanent remote archive of every physics simulation performed by users.

Temporary simulation values may remain while the extension is open so that the current scene can be rendered and updated correctly.

Any locally stored functional preferences, if used, may remain until they are changed, cleared, or removed through browser or extension controls.

40. Data Security

Miniature Pendulum Sandbox is designed to minimize unnecessary handling of user information.

Running the core physics simulation locally reduces the need to transmit simulation information to external systems.

However, no browser extension, operating system, device, or electronic environment can be guaranteed to be completely secure.
