Privacy Policy

Sensei (“we,” “our,” or “us”) is operated by Jishu Labs LLC. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our AI-powered code analysis platform at sensei.jishulabs.com (the “Service”). We are committed to protecting your privacy and the confidentiality of your code.

We collect the following types of information:

• Account information: Email address and password when you create an account.
• Code submissions: Code snippets you submit for analysis, stored in your personal encrypted history.
• Analysis results: AI-generated explanations, scores, issues, and suggestions for each analysis.
• Usage data: Number of analyses performed, languages analyzed, and feature usage patterns.
• Device information: Browser type, operating system, and IP address for security and analytics purposes.
• Product analytics: Pages visited, clicks, scroll depth, page performance (Core Web Vitals), JavaScript errors, and session replays, recorded with PostHog. Replays mask everything you type, and on signed-in workspace pages they mask all on-screen text, so the code in your workspace is not captured.

• To provide and maintain the code analysis Service
• To process your code submissions and generate analysis results
• To maintain your personal analysis history and statistics
• To communicate important service updates and security notices
• To enforce usage limits (e.g. free-tier monthly analysis cap)
• To improve the accuracy and quality of our AI analysis

Your code privacy is our top priority. Code submitted for analysis is processed securely and stored only in your personal, encrypted analysis history. We never share your code with third parties, use your code to train our AI models, make your code accessible to other users, or sell or license your code in any way. You can delete your analysis history at any time through Settings.

Your data is stored securely using Supabase with PostgreSQL, protected by Row-Level Security (RLS) policies that ensure only you can access your own data. We retain your data for as long as your account is active. You may export all your data at any time via Settings, and you may request complete account deletion — which removes all associated data permanently.

We use the following third-party services:

• Supabase: Authentication and database hosting.
• AI model providers: For processing code analysis. Code is sent securely via API.
• PostHog: Product analytics and session replay, provided by PostHog, Inc. and hosted in the United States. This data is not sold or used for advertising, and it is not used to train AI models.

You have the right to access your personal data, export your data in JSON format, correct inaccurate information, delete your account and all associated data, and opt out of non-essential communications. To exercise these rights, visit Settings or contact us at the email below.

We use essential cookies for authentication and session management, and PostHog analytics cookies and local storage (names start with ph_) for product analytics. The analytics storage is set on .jishulabs.com and shared with jishulabs.com and the other Jishu Labs tools. If you declined cookies on jishulabs.com, analytics is not loaded. We do not use advertising cookies. See our Cookie Policy for details.

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the “Last updated” date. We encourage you to review this page periodically.
