Privacy Policy for TOEICAICoach

Last updated: July 1, 2026

TOEICAICoach is a TOEIC-style practice application for English learners. This Privacy Policy explains how the app handles information when you use the app.

1. Information We Handle

The app does not require account registration and does not ask you to enter your name, email address, phone number, contacts, photos, location, microphone, camera, or health data.

The app may handle the following information:

• TOEIC part selection, such as Part 5, Part 6, or Part 7.
• The number of questions requested.
• Practice questions temporarily stored on your device so the app can show generated or cached questions smoothly.
• Technical information automatically processed by third-party services, such as IP address, device or advertising identifiers, app interaction data, crash or diagnostic information, and network request metadata.

2. AI Question Generation

When you request new practice questions, the app sends a request to our Cloudflare Worker backend. The backend sends a prompt to an AI service to generate TOEIC-style practice questions.

The app does not intentionally send your name, email address, precise location, contacts, photos, or other sensitive personal information to the AI service. You should not enter personal or confidential information into the app.

Third-party providers involved in question generation may process request metadata as part of providing and securing their services.

3. Advertising

The app uses Google AdMob to display ads. AdMob and related Google services may collect or receive information from the app and your device to provide ads, measure ad performance, prevent fraud, and comply with applicable laws.

Depending on your region and device settings, ads may be personalized or non-personalized. Where required, consent or privacy choices may be requested or managed through Apple, Google, or device-level privacy controls.

For more information, please review Google's privacy information: https://policies.google.com/privacy

4. Third-Party Services

The app and backend use the following third-party services:

• Google AdMob: advertising and ad measurement.
• Cloudflare Workers: backend hosting, routing, security, and request processing.
• AI question generation service: TOEIC-style practice question generation.
• Apple services: App Store distribution, device privacy controls, and system diagnostics where applicable.

These third parties may process data according to their own privacy policies and terms.

5. Data Storage

Practice questions may be cached locally on your device. You can remove locally stored app data by deleting the app from your device.

The backend does not require user accounts. Server and service providers may keep logs for security, abuse prevention, debugging, analytics, and legal compliance.

6. Data Sharing

We do not sell personal information. Information may be shared with third-party service providers only as needed to operate the app, generate practice questions, display ads, maintain security, prevent abuse, and comply with legal obligations.

7. Children

TOEICAICoach is intended for general English-learning use and is not directed specifically to children. The app is not intended to be submitted under Apple's Kids Category. Users should use the app under the supervision of a parent or guardian where required by local law.

8. TOEIC Trademark Notice

TOEIC is a trademark of ETS. TOEICAICoach is an independent study tool and is not affiliated with, endorsed by, or sponsored by ETS or the TOEIC program.

9. Your Choices

You can:

• Delete the app to remove locally stored app data.
• Use iOS privacy settings to limit tracking or reset advertising-related settings.
• Manage ad privacy choices through Google or device-level privacy controls where available.

10. Changes to This Policy

We may update this Privacy Policy when the app, backend, third-party services, or legal requirements change. The updated version will be identified by the latest updated date.
