Privacy Policy

1. Who we are

SpeakCoach (“the Service”) is operated by TAKE A Inc. (“we”, “us”), a company registered in Tokyo, Japan. The Service is delivered as a web application and a Chrome extension. This policy explains what we collect, why, who we send it to, and how to get it deleted.

2. What we collect

2.1 Through the Chrome extension

When you open a lesson on a supported online English platform and explicitly press “Start recording”, we capture:

• Your microphone audio (your own speech).
• The lesson tab’s audio output (your teacher’s speech) — only on platforms whose terms of service permit recording. On platforms that do not permit it, we record you only.
• Session start and end time, and duration.
• The name of the microphone device in use, during the lesson only, to detect audio-quality problems.
• The host name only of the lesson page you recorded (for example, nativecamp.net), so we can tell which platform the lesson came from and isolate platform-specific quality issues. We do not collect the full URL, the page path, or any search terms, and we never collect your browsing history for pages you are not recording.

Recording continues until you press “Stop”, until you leave the lesson page, or until the tab is closed. Nothing is captured before you press start.

2.2 Generated and stored on our servers

• A transcript of the audio (English text).
• Pronunciation assessment results (per-word scores, IPA notation, points to improve).
• Conversation analysis (fluency, vocabulary and grammar scores, and specific corrections).
• Coaching feedback and review material derived from the above.

2.3 Word lookup

If you use the word lookup feature in the extension, the query you type is sent through our servers to an external AI provider.

2.4 Account and usage data

• Your email address and authentication tokens, so that the extension and the web app know who you are.
• Service usage logs and product analytics events (which screens and features were used).
• Anything you send us when you contact support.

3. Why we use it

• To transcribe your lesson audio.
• To generate pronunciation assessment and improvement feedback.
• To generate grammar, vocabulary and fluency coaching.
• To track your progress over time so you can compare past lessons.
• To provide, operate, maintain and improve the Service.
• To provide support.
• To prevent abuse and keep the Service secure.

4. Service providers

We use service providers to deliver the Service. They process your data only on our instructions, under contracts that require appropriate security.

• Speech-recognition and AI providers — transcription, pronunciation assessment, coaching and word lookup.
• A cloud storage provider — audio files, transcripts and analysis results.
• Cloud hosting and email providers — running the Service and sending email.
• Stripe — payment processing and billing details. We never store your card number; Stripe handles it directly.

Payments. For purchases outside Japan, Link (a Stripe service) may act as the merchant of record. In that case Link issues receipts and invoices, provides transaction-level support, and your card statement shows a descriptor beginning withLINK.COM. For purchases made in Japanese yen from Japan, we remain the seller.

Analytics and advertising. To understand usage, investigate problems and measure advertising, we use PostHog, Google Analytics, Vercel Analytics, Microsoft Clarity, and the advertising tags of Meta, X, TikTok and OpenAI. These record pages viewed and actions taken through cookies and similar technologies. You can refuse them through your browser settings or each provider’s opt-out.

Where your data is processed. Audio files, transcripts and analysis results are stored in Seoul, South Korea. Our service providers may process data in the United States and other countries. If you are in the EEA or the UK, this means your data is transferred outside your region; see section 9. Email us for the names of our service providers or a copy of the safeguards we rely on.

5. AI processing

• We apply automated AI processing to your audio and transcripts solely to deliver the features described above.
• We do not use your recordings or transcripts to train AI models of our own.
• Requests to our speech-to-text and language-model providers use available no-training or model-improvement opt-out controls.
• AI output is advisory. We do not guarantee its accuracy or completeness.

6. Chrome extension permissions

Each permission is used only for the stated purpose.

• tabCapture — to capture the teacher’s audio from the lesson tab, on platforms where that is permitted. It runs only after you press “Start recording”, and never touches audio from any other tab.
• offscreen — required by Chrome Manifest V3 to run the recording pipeline outside the service worker.
• storage — to keep your settings and your authentication tokens.
• cookies — to synchronise sign-in state between the extension and speakcoach.takea.co.jp only. No cookies are read from third-party domains.
• host_permissions (lesson sites) — to show the control panel on the lesson page and to capture lesson audio.
• host_permissions (speakcoach.takea.co.jp) — to upload recordings and retrieve results from our API.
• Microphone access — to record your own speech. Requested when you first press “Start recording”, and released promptly when you stop.

7. Sharing with third parties

We do not sell your personal data. We disclose it only when:

• You have consented.
• We are required to by law.
• It is necessary to protect life, health or property.
• It is provided to a service provider described in section 4, within the scope needed to run the Service and under appropriate supervision.

8. Storage and security

• All traffic is encrypted in transit over HTTPS.
• Audio files are stored encrypted in Supabase Storage.
• Database access is protected by authentication and authorisation controls.
• We take measures to prevent unauthorised access, loss, destruction, alteration and leakage.

9. Your rights

You can request access to, correction of, or deletion of your personal data at any time by emailing us. You can also delete an individual lesson from within the app, uninstall the extension to stop any further capture, and revoke microphone or tab-audio permission from your browser settings at any time.

If you are in the EEA or the UK (GDPR)

Our legal basis is performance of a contract with you for the features you ask for, and your consent for the recording itself — which you give each time by pressing “Start recording”. You have the right to access, rectification, erasure, restriction of processing, data portability, and to object to processing. You may lodge a complaint with your local supervisory authority. Where required, transfers outside the EEA are protected by the transfer mechanisms in our applicable processor agreements, including standard contractual clauses or an equivalent lawful mechanism.

If you are in California (CCPA/CPRA)

You have the right to know what personal information we collect and why, to request deletion, to request correction, and not to be discriminated against for exercising those rights. We do not sell your personal information. The analytics and advertising tools we use are described in section 4.

10. Retention and deletion

While your account is active we keep your lesson recordings, transcripts and analysis so that you can review and compare past lessons. You can delete an individual lesson at any time from the app.

If you close your account, we delete the recordings, transcripts and analysis results associated with it within 30 days.

11. Cookies

We use cookies and similar technologies to operate the Service, keep you signed in, improve the product, understand usage and measure advertising. Refusing cookies in your browser settings may prevent parts of the Service from working.

12. Children

The Service is intended for general language learners. We do not knowingly collect personal data from children under 16. If you believe a child has provided us with personal data, contact us and we will delete it.

13. Changes to this policy

We may update this policy. If a change is material we will notify you within the Service. The updated policy takes effect when it is posted on this page.
