Privacy Policy

Last Updated: May 28, 2026

1. Introduction

Welcome to PerfSentinel ("we," "our," or "us"). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your personal information when you use our website, CLI tool, GitHub application, and related services (collectively, the "Service").

Our Core Commitment: Complete Code Privacy

PerfSentinel is a developer-first tool designed to analyze React component performance regression inside your own CI/CD environment. We do not upload, collect, transmit, or store your application source code, components, or test files on our servers. All processing is performed locally inside your secure isolated build containers.

2. Information We Collect

We collect minimal information necessary to deliver and manage the Service:

  • Account and Profile Data: Contact details such as your name, company name, work email address, and GitHub username when you join our waitlist, register, or connect your GitHub account.
  • Billing Information: Payment details processed securely through our third-party payment processor (e.g., Stripe). We do not store your credit card details on our servers.
  • Performance Metrics Metadata: Aggregate, non-sensitive telemetry data containing execution runtimes, component render counts, and memory numbers for performance report rendering. This metadata does not contain source code or proprietary intellectual property.
  • Usage Data: Basic technical logs, IP addresses, browser types, and interactions with our website to diagnose issues and optimize performance.

3. How We Use Your Information

We use the collected information for the following purposes:

  • To provide, maintain, and optimize the Service.
  • To securely process payments and manage your subscription.
  • To communicate with you, including answering support queries, delivering waitlist updates, and sending transaction receipts.
  • To monitor and analyze aggregate technical performance trends to ensure platform stability.

4. Information Sharing and Disclosure

We do not sell, trade, rent, or lease your personal information to third parties. We share information only with trusted service providers to operate our business, such as payment processors (Stripe) and transactional email providers (e.g., Resend, Postmark). These processors are bound by strict data protection agreements.

5. Data Retention

We retain your account and metadata information for as long as your account is active or as needed to provide you the Service. You may request deletion of your account and metadata at any time by contacting us.

6. Security

We employ industry-standard encryption (SSL/TLS) and security measures to protect your account metadata and billing transaction details. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

7. Your Rights (GDPR & CCPA Compatibility)

Depending on your location, you may have rights under applicable privacy laws (such as GDPR in Europe or CCPA/CPRA in California), including the right to access, correct, port, or request deletion of the personal data we hold about you. To exercise these rights, please email us.

8. Changes to this Policy

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.
