Privacy Policy

Effective Date: May 13, 2026

CELTESTPIP, operated by STARMOON TECHNOLOGIES INC. ("Company", "we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your personal information when you visit our website https://www.celtestpip.com (the "Site").

By accessing or using our services, you agree to the collection and use of your information in accordance with this Privacy Policy. If you do not agree with the terms herein, please do not use the Site.

1. Information We Collect

1.1 Information You Provide to Us

When you create an account or contact us, we collect the following information:

  • Full name
  • Email address

This data is collected solely for account creation, communication, and providing access to our services.

1.2 Payment Information

We use third-party payment processors to manage payments. We do not store your credit card information on our servers. All payment data is handled securely by our payment gateway provider.

1.3 CELTESTPIP Teacher (AI Chat) Data

When you use the CELTESTPIP Teacher — our in-product AI English coach and support chatbot — we collect and store:

  • The messages you send (questions, follow-ups, and any text or transcripts you choose to paste into the chat).
  • The messages the AI replies with, including any tool results the AI surfaces back to you (for example, a summary of your recent practice history or your current subscription status).
  • Basic session metadata: the chat ID, timestamps, the platform you're chatting from (web, iOS, or Android), browser (web only), and your interaction with feedback controls (thumbs up / thumbs down).
  • A transient context block assembled at request time so the AI can personalize its replies — this includes your first name, last name, Pro membership status, and the read-only tool data the AI requests (subscription details, recent practice history, skill scores, refund status when relevant).

You control what you send. Do not paste sensitive information (passwords, full credit card numbers, government IDs, medical records, etc.) into the chat — there is no use case in which the Teacher needs that data.

2. How We Use Your Information

We use the information we collect to:

  • Create and manage your account
  • Provide access to purchased content
  • Communicate with you regarding your account, updates, or support requests
  • Improve our platform and user experience
  • Enforce our terms and protect the integrity of our service
  • Operate the CELTESTPIP Teacher AI chat feature: route your messages to a third-party AI provider so the assistant can generate a reply, persist your chat history so you can revisit and resume past conversations, and use anonymized usage signals (latency, error rates, thumbs-up/down feedback) to improve the assistant's quality and reliability.

We do not use your chat content to train AI models. We do not use your chat content for advertising. Our AI providers operate under zero-retention or contractually-bound retention terms — they do not use your messages to train their own models.

3. Data Sharing and Disclosure

We do not sell, rent, or trade your personal information to third parties. We may share your data only in the following limited circumstances:

  • Service Providers: With trusted third parties who assist in operating our website (e.g., payment processors, hosting, email delivery), under strict confidentiality agreements.
  • AI Providers (CELTESTPIP Teacher): When you send a message to the Teacher chat, the message text and the personalization context block described in §1.3 are transmitted to our LLM provider (currently OpenRouter, which routes to model providers including Anthropic) so the assistant can generate a reply. We may also send anonymized request metadata (latency, error rates, model-call traces) to an LLM observability provider (currently Langfuse) so we can monitor and improve the feature. These providers process the data on our behalf under their own privacy and data-processing terms; they do not use your messages to train their models.
  • Legal Obligations: When required by law, regulation, or court order.

4. Data Security

We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the Internet or method of electronic storage is 100% secure. Therefore, we cannot guarantee its absolute security.

5. Cookies and Tracking Technologies

We use cookies and similar technologies to:

  • Maintain session information
  • Personalize your experience
  • Analyze platform usage to improve performance

You can disable cookies through your browser settings, but doing so may affect your ability to use certain features of our site.

6. Data Retention

We retain your personal data only as long as necessary to:

  • Provide our services
  • Comply with legal obligations
  • Resolve disputes
  • Enforce our agreements

CELTESTPIP Teacher chats are retained for 60 days from the date of the last message in the conversation, after which they are automatically expired and removed from view.

Upon request or account deletion, we will remove your personal data from our systems unless required to retain it by law.

7. Your Rights and Choices

You may:

  • Access and update your account information at any time
  • Request the deletion of your personal data
  • Opt out of non-essential communications
  • Wait for CELTESTPIP Teacher chats to be automatically removed after 60 days, or contact us to request earlier deletion of specific conversations
  • Decline to use the Teacher chat entirely — it is an optional feature, and the rest of the platform works without it

To exercise your rights, please contact us at [email protected].

8. International Users

Our services are operated from Canada. If you are accessing the Site from outside Canada, please be aware that your data may be transferred to, stored, and processed in Canada where our servers are located.

9. Children's Privacy

CELTESTPIP is intended for users 18 years of age or older. We do not knowingly collect or solicit personal information from anyone under the age of 18. If we become aware that we have collected personal data from a child without verification of parental consent, we will take steps to delete that information.
