BilinCo TrainerPrivacy Policy
Effective date: June 10, 2026 · Last updated: September 25, 2026
This Privacy Policy describes how BilinCo Language Services LLC (Monrovia, California) ("BilinCo," "we," "us," or "our") collects, uses, and shares personal information when you use BilinCo Trainer (the "Service"). By using the Service, you agree to the practices described here.
1. Information We Collect
Information you provide
- Account information: email address, username, display name, and an optional avatar image.
- Google sign-in: if you sign in with Google, we receive basic profile information from your Google account via OAuth (such as your email address, name, and profile picture). We do not receive your Google password.
- Practice and study data: your practice renditions and quiz answers, scores, progress, streaks, and achievements.
- Uploaded documents: case documents you upload to the Case Prep feature, which are processed to generate preparation materials for you.
- Communications: messages you send us, such as support or refund requests.
- Readiness report email (optional): if you ask us to email you your result from the free readiness check, we store the email address you enter, your score, readiness band and weakest category, whether you ticked "Also send me occasional exam-prep tips" (unticked by default), and when you submitted it.
Guest mode
You can start training without signing in. When you do, we create a temporary guest account on this device: a random guest identifier with no name or email attached, and a sign-in token saved in your browser. Your practice attempts, scores and progress are stored under that guest account like any other account. If you later sign in with Google, we merge your guest progress into your Google account and then delete the guest account. Because a guest account has no email, clearing your browser storage disconnects you from it.
Payment information
Payments are handled by Stripe. Your card number is collected and processed directly by Stripe; we never store card numbers. We receive from Stripe only the information needed to manage your plan, such as transaction status, plan type, and the last four digits of your card.
Information collected automatically
Like most online services, our servers record basic technical information such as IP address, browser type, and request logs, which we use for security and to operate the Service.
2. How We Use Information
- To provide the Service: accounts, lessons, practice exams, scoring, progress tracking, and leaderboards;
- To generate AI-assisted scoring and feedback on the practice text you submit;
- To process payments and manage subscriptions through Stripe;
- To send transactional emails such as password resets;
- To email you the readiness report you asked for and, only if you opted in, occasional exam-prep tips;
- To provide guest mode and carry your guest progress over when you sign in;
- To maintain security, prevent abuse, and enforce our Terms of Service;
- To improve the Service.
We do not use your personal information for third-party advertising, and we do not sell personal information.
3. AI Scoring: What We Send
When you submit a practice rendition for scoring, the practice text you submit is sent to our AI scoring provider (Anthropic Claude) to generate your score and feedback report. Exam prompt text is also sent to text-to-speech providers to produce audio. We do not send your password or payment details to AI providers. Please do not include sensitive personal information in practice renditions or uploaded documents beyond what is needed for your training.
4. Service Providers and Subprocessors
We share personal information only with the service providers that help us run the Service:
| Provider | Purpose |
|---|---|
| Stripe | Payment processing and subscription billing |
| Optional sign-in via Google OAuth | |
| Render | Application and database hosting |
| Anthropic (Claude) | AI scoring of submitted practice renditions |
| OpenAI, ElevenLabs, Microsoft | Text-to-speech audio of exam content |
| Resend | Email delivery (password resets, readiness reports you request, and exam-prep tips if you opted in) |
These providers process data on our behalf and are not permitted to use it for their own purposes except as required to provide the service or by law. We may also disclose information if required by law or to protect our rights, users, or the public.
5. Local Storage and Cookies
The Service uses your browser's localStorage to save progress and preferences (for example, lesson position, interface settings, and cached practice state) so the app works smoothly between visits. The readiness check saves your latest result (score, band and weakest category) on your device so the app can suggest where to start, and guest mode saves your guest sign-in token there. This storage is functional, not advertising: we do not use ad tracking, and there are no third-party advertising cookies on the Service. You can clear localStorage through your browser settings; doing so may reset locally saved preferences.
6. Leaderboards and Public Visibility
If you participate in practice activities that feed the leaderboard, your display name, avatar, and scores may be visible to other users of the Service. Your email address is never shown on leaderboards. You can change your display name or avatar at any time in your account settings, which changes what other users see. If you would like your entries removed from the leaderboard entirely, contact us at info@bilinco.net.
7. Data Retention
We retain your account data, progress, and User Content for as long as your account exists, so your training history remains available to you. Guest account data is kept until it is merged into your account when you sign in; unmerged guest accounts are deleted automatically once they are more than 35 days old (guest sign-in tokens expire after 30 days). Readiness report emails and tips preferences are kept until you ask us to delete them; asking us to stop tips stops the emails. If you request deletion of your account, we delete your personal information except where we must retain limited records to comply with legal, tax, or accounting obligations (for example, payment records held by Stripe).
8. Your Rights
You may request access to, correction of, or deletion of your personal information at any time by emailing info@bilinco.net from the email address associated with your account. We will respond within a reasonable time and verify your identity before acting on the request.
Readiness emails and tips: to stop exam-prep tips, or to have your readiness report email and result deleted, write to info@bilinco.net from the address you entered, with the subject "Unsubscribe" or "Delete my data." Stopping tips does not affect your account.
9. California Residents (CCPA)
If you are a California resident, the California Consumer Privacy Act (CCPA) gives you specific rights regarding your personal information:
- Categories collected: identifiers (email, username, display name, IP address); customer records (subscription and transaction information, excluding card numbers); internet activity (usage of the Service, including readiness check results); audio or visual data (optional avatar); and user-provided content (practice renditions, uploaded documents).
- Right to know: you may request details about the personal information we have collected about you.
- Right to delete: you may request deletion of your personal information, subject to legal exceptions.
- Right to correct: you may request correction of inaccurate personal information.
- No sale or sharing: we do not sell personal information and do not share it for cross-context behavioral advertising, and we have not done so in the preceding 12 months.
- Non-discrimination: we will not discriminate against you for exercising your CCPA rights.
To exercise these rights, email info@bilinco.net with the subject "Privacy Request." An authorized agent may submit a request on your behalf with proof of authorization.
10. Children
The Service is not directed to children under 16, and we do not knowingly collect personal information from children under 16. If you believe a child under 16 has created an account, contact us at info@bilinco.net and we will delete the account.
11. Security
We use reasonable technical and organizational safeguards to protect your information, including TLS encryption for data in transit and hashed passwords (we never store passwords in plain text). No method of transmission or storage is completely secure, so we cannot guarantee absolute security; please use a strong, unique password.
12. International Transfers
The Service is hosted in the United States. If you access the Service from outside the United States, your information will be transferred to, stored, and processed in the United States, where data protection laws may differ from those of your jurisdiction. By using the Service, you consent to this transfer.
13. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will provide notice through the Service or by email before the changes take effect. The "Effective date" above shows when this policy was last updated.
