Privacy Policy for Ace Language Learning

Effective date: March 9, 2026

Ace Language Learning is a Chrome extension designed to help users learn English on YouTube through subtitle reading, vocabulary lookup, pronunciation playback, and optional AI-assisted explanation.

1. What the extension does

Ace Language Learning works on YouTube watch pages and provides learning tools such as subtitle display, word lookup, pronunciation playback, and optional AI-based translation or explanation.

2. Data processed by the extension

The extension may process the following data in the browser:

3. Local storage

The extension stores settings and optional user-provided AI configuration locally in the browser using Chrome extension storage. This data is used only to operate the extension’s features on the user’s device.

4. No developer-operated backend for core features

The core features of Ace Language Learning do not require a developer-operated backend server, developer account, or proprietary online service.

5. Optional AI features

If the user chooses to enable AI features, the extension sends the selected subtitle text or user-requested content directly to the third-party AI provider configured by the user. These requests are not proxied through a developer-operated backend.

The user is responsible for choosing and configuring their own AI provider and API key. Use of those third-party services is subject to the privacy policy and terms of the selected provider.

6. Data sharing

The developer does not sell personal data.

The extension does not share user data with the developer for advertising purposes.

If the user enables optional AI functionality, relevant text is transmitted directly to the third-party AI provider selected by the user in order to generate the requested translation or explanation.

7. Advertising

Ace Language Learning does not use user data for advertising, marketing profiling, or personalized ads.

8. Account and login

The current version of the extension does not require a developer-operated user account for its core functionality.

9. Children

The extension is not specifically directed to children under 13.

10. Changes to this policy

This Privacy Policy may be updated from time to time. Any updates will be reflected in the latest published version of this policy.
