Privacy Policy

Last updated: February 14, 2026

1) Introduction

Welcome to Lexis (“Lexis,” “we,” “our,” or “us”). This Privacy Policy explains what information we collect, how we use it, how we share it, and the choices you have when you use Lexis (the “Service”).

2) Information We Collect

2.1 Information you provide

We collect information you provide directly, including:

  • Account information (such as email address and authentication identifiers) when you create an account or sign in.
  • User content you upload or create in the Service, such as:
    • EPUB files and related content you upload
    • Vocabulary lists, notes, highlights, bookmarks
    • Reading progress and learning activity (e.g., flashcard review history)
    • Language preferences and app settings
  • Support communications (such as messages you send us).

2.2 Information collected automatically

When you use the Service, we (and our infrastructure providers) may automatically collect:

  • Log and device data, such as IP address, device/browser type, timestamps, pages/actions performed, and error logs (for security and reliability).
  • Operational metadata needed to run the Service (for example, whether an upload succeeded).

No third-party analytics (currently): We do not currently use third-party analytics or advertising trackers. Basic server logs may still be generated for security, abuse prevention, and debugging.

3) How We Use Information

We use information to:

  • Provide and operate the Service (authentication, uploads, reading progress, vocabulary, flashcards).
  • Process translations you request.
  • Secure the Service and prevent abuse.
  • Maintain and improve reliability (debugging and performance monitoring).
  • Respond to support requests and communicate service-related notices (e.g., policy updates).
  • Comply with legal obligations and enforce our terms.

4) How We Share Information

We do not sell your personal information. We share information only as described below.

4.1 Service providers

We use trusted service providers to operate the Service (for example: hosting, database, file storage, authentication, and translation providers). These providers process information on our behalf to provide and secure the Service.

4.2 Legal and safety

We may disclose information if we believe it is reasonably necessary to:

  • comply with law or legal process,
  • protect the rights, safety, and security of the Service, our users, or the public,
  • investigate, prevent, or take action regarding fraud, abuse, or security issues.

4.3 Business changes

If the Service is transferred (e.g., acquisition or asset transfer), information may be transferred as part of that transaction.

5) Translation Requests

If you use translation features:

  • What we send: the text you choose to translate (typically the selected excerpt or minimum necessary text) and the target language.
  • When we send it: only when you initiate a translation action or use a feature that requires translation.
  • Accuracy: translations may be inaccurate or incomplete and should not be relied on as professional advice.

Avoid translating sensitive personal information if you do not want it processed by a translation provider.

6) Cookies and Similar Technologies

We use essential cookies and/or local storage required for login, session management, and security. We do not currently use advertising cookies or third-party analytics cookies.

7) Data Security

We use reasonable safeguards designed to protect information. However, no system is 100% secure and we cannot guarantee absolute security.

8) Data Retention

We retain information as long as needed to provide the Service and for legitimate purposes such as security and dispute resolution.

  • Account data and user content: retained while your account is active.
  • If you delete your account: we aim to delete or anonymize your account data and user content within 30 days, except where retention is required for legal/security reasons.
  • Backups: may persist for up to 90 days before being overwritten.
  • Security/operational logs: may be retained for up to 30 days (or longer if needed to investigate abuse/security incidents).

9) Your Rights and Choices

Depending on where you live, you may have rights to access, correct, delete, or obtain a copy of your information, and to object to or restrict certain processing where applicable.

To request these, contact us at triangleofalpha@gmail.com. We may need to verify your identity.

10) International Data Transfers

We and our service providers may process and store information in countries other than where you live. Those countries may have different data protection laws.

11) Children's Privacy

Lexis is not intended for children under 13 (or the minimum age required in your jurisdiction). If you believe a child has provided personal information, contact us and we will take steps to delete it.

12) Changes to This Policy

We may update this Privacy Policy from time to time. We will update the “Last updated” date when changes are posted.
