Introduction
Welcome to Einsia (referred to as "we," "us," or "our service"). We take your privacy and personal information protection seriously. This Privacy Policy explains how we collect, use, store, and protect your personal information, as well as the rights you have regarding this information.

How We Use Your Information
The information we collect is used for the following purposes:
- Provide, maintain, and improve our services
- Personalize your user experience
- Process your requests and feedback
- Send service-related notifications and updates
- Conduct data analysis to improve product features

Information Sharing and Disclosure
We do not sell your personal information. We may share your information under the following circumstances:
- With your explicit consent
- With third-party service providers who provide services to us (such as cloud storage services)
- To comply with laws and regulations or respond to legitimate legal processes
- To protect the rights, property, or safety of us, our users, or the public
Data Security
We employ industry-standard security measures to protect your personal information, including data encryption, access controls, and security audits. However, please note that no method of Internet transmission or electronic storage is 100% secure, and we cannot guarantee absolute security.
Data Retention
We retain your personal information for as long as necessary to fulfill the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law. When you delete your account, we will delete or anonymize your personal information within a reasonable timeframe.
Data Access Clarification
We only access the minimum necessary data required to provide its core functionality within Overleaf. We do not access, read, or process user content outside of the active session where the user explicitly invokes the extension. Einsia does not monitor browsing activity, collect unrelated website data, or access personal files on the user's device.
All data access is strictly limited to enabling requested features such as generating LaTeX tables, figures, equations, citations, or fixing LaTeX errors. Users maintain full control over when the extension is activated and what content is processed.
Data Storage Clarification
We do not permanently store users' manuscript content unless explicitly required for account-related services or feature improvement with user consent. Any temporary processing of content is performed securely and is not retained beyond what is necessary to complete the requested action.
Extension Permissions Explanation
We request only the Chrome extension permissions necessary to operate within Overleaf and deliver its features. Permissions are used solely to enable interaction with Overleaf pages and provide AI-assisted writing functions.
The extension does not use its permissions to access unrelated websites, track user behavior across the web, or collect personal browsing history. All permissions are strictly limited to the functional scope described in this Privacy Policy.
Your Rights
Under applicable data protection laws, you may have the following rights:
- Access and obtain a copy of your personal information
- Correct inaccurate personal information
- Request deletion of your personal information
- Restrict or object to our processing of your information
- Data portability
- Withdraw consent
Cookies and Similar Technologies
We use cookies and similar technologies to collect usage data, remember your preferences, and provide personalized experiences. You can manage cookie preferences through your browser settings, but disabling certain cookies may affect the functionality of the service.
Children's Privacy
Our service is not directed to children under the age of 16. We do not knowingly collect personal information from children under 16. If you discover that we may have collected information from a child, please contact us immediately.

We may update this Privacy Policy from time to time. The updated policy will be posted on this page with the last updated date noted. For significant changes, we will notify you through appropriate means. We recommend that you review this policy regularly to stay informed.
