Relens

Privacy Policy

Last updated: February 2026

1. What We Collect

Relens collects two categories of data:

Account data: When you sign in, we receive your name, email address, and profile picture from your OAuth provider (Google, GitHub, or Microsoft). We also store hashed API keys and subscription status.

Performance telemetry: When you instrument a React application with the Relens npm package, we receive component names, render durations, effect firing patterns, network request metadata (URLs, status codes, timing), and user interaction events (element selectors, event types). We do not collect source code, DOM content, input values, passwords, cookies, or personal data from your application's end users.

2. How We Use Your Data

Account data is used to authenticate you, manage your subscription, and communicate service updates. Performance telemetry is used solely to provide the Relens service — displaying data in the DevTools panel and exposing it via MCP tools to your AI agent.

We do not use your telemetry data for analytics, advertising, model training, or any purpose beyond providing the service to you.

3. Data Retention

Performance telemetry is stored in memory only and is never persisted to disk. Data is automatically deleted when your WebSocket session ends or the server restarts. There is no long-term telemetry storage.

Account data is retained as long as your account is active. You can request deletion of your account and all associated data at any time by contacting support.

4. Third Parties

We use the following third-party services:

  • Stripe — Payment processing. Stripe receives your payment details directly; we never see or store your full card number.
  • OAuth providers (Google, GitHub, Microsoft) — Authentication. We receive only the profile data you authorize.
  • Hosting provider — Server infrastructure. The hosting provider has physical access to the server but does not access application data.

We do not sell, rent, or share your data with any other third parties.

5. Cookies

The Relens marketing site uses no tracking cookies or analytics. The portal (portal.relens.dev) uses a session cookie for authentication. The Chrome extension stores your API key and preferences in Chrome's local storage.

6. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion of your account and all associated data
  • Export your account data
  • Withdraw consent for data processing at any time

To exercise any of these rights, contact us at support@relens.dev.

7. GDPR Compliance

For users in the European Economic Area, we process personal data under the following legal bases: contract performance (providing the service), legitimate interest (improving the service), and consent (where applicable). Our data processing is minimal by design — telemetry is ephemeral and contains no personal data from your application's end users.
