개인정보 처리방침

Effective Date: May 22, 2026

This Privacy Policy describes how Letspeaky ("we," "our," or "us") collects, uses, shares, and protects the information obtained from users ("you" or "your") of our online language self-study platform, including our website at Letspeaky.com, all subdomains under the *.Letspeaky.com ecosystem (such as mate.Letspeaky.com), and related mobile applications (collectively, the "Service").

1. Nature of the Service

Letspeaky is an interactive, digital self-study and practice software application designed to help users practice their listening, speaking, reading, and writing skills in multiple languages through natural voice interactions and simulated conversational topics.

Letspeaky is a digital utility tool designed for personal language practice and self-study. It is not a formal educational institution, training school, academic curriculum, or licensed educational entity, and does not provide or recognize official academic credits, formal degrees, or professional certifications.

2. Information We Collect

We collect the following categories of information to operate and improve our self-study tool:

• User Profile Information: When you create an account, we collect your email address, username, and secure password hashes. If you register or log in using third-party services (such as a Google account), we receive your basic public profile information (name, email, and profile picture url) as permitted by your provider's settings.
• Practice Progress & Statistics: To track your language practice history, we collect data regarding completed lessons, correct/incorrect answer statistics, active learning streaks, daily energy usage, selected practice voices, and preferred study modes.
• Audio & Microphone Inputs: For interactive speaking and pronunciation practice, the Service requests microphone access. Raw audio inputs from the microphone are processed strictly in real-time on your browser for pronunciation feedback or streamed securely via encrypted connections to trusted speech-to-text API partners solely for real-time translation and learning transcriptions. We do not record, store, harvest, or distribute any of your audio files or voice recordings on our servers.
• System Security & Essential Cookies: To prevent fraud, spam, or unauthorized access, our security systems may temporarily log basic server connection details. Additionally, we use essential technical cookies solely to maintain your secure login session and remember your language preferences.

3. How We Use Your Information

Your information is processed solely for the following purposes:

• To provision, operate, maintain, and secure your personal account and learning statistics.
• To analyze your speech pronunciation and provide instant, automated accuracy feedback.
• To measure usage trends, prevent malicious activities, detect bugs, and continuously improve the software interface.
• To serve relevant advertisements through third-party ad networks on the Service.

4. Data Sharing

We commit not to sell, trade, or transfer your personal information to third parties. Data is only shared in the following necessary cases:

• Service Providers: Units that support system operation, ad distribution, or anonymous service performance analysis, all of which must strictly comply with data confidentiality agreements.
• Legal Compliance: Disclosing information when legally required by competent authorities or to protect the safety and legal rights of users and the system.

5. User Cookies

We use essential cookies to maintain login status, remember language settings, and ensure account security. You can freely manage or disable cookies through your browser settings; however, some features of the Service may not function fully without them.

6. Data Security

We implement optimal security measures to protect your personal information and learning data from unauthorized access, alteration, or disclosure.

7. Account Deletion and Data Removal

We respect your control over your personal data. You can actively remove your account, linked email, learning history, and streak at any time by navigating to the Profile section in the app or website and selecting "Delete Account". The system will automatically process this to remove most of your personal profile information. Please note that certain necessary data, such as transaction history and invoices (if any), will still be securely stored to comply with current legal and financial obligations.

8. Children's Privacy

Our Service is directed to a general audience. If you are under the age of 13, you are only permitted to register and use the Service with the consent, supervision, or account setup by a parent or legal guardian. We do not knowingly collect personal information directly from children under 13 without parental consent. If we detect an invalid case of collecting children's data outside of parental control, we will immediately purge that information from our system.

9. Changes to This Policy

We may update this Privacy Policy periodically to reflect shifts in technology, law, or business practices. Significant revisions will be notified through notice highlights inside our app.
