Privacy Policy

Overview

This Privacy Policy explains how CSSVis Lab handles information when you use our website, dashboard, and browser extension.

CSSVis Lab is built to inspect and organize design information from webpages you choose to analyze. We try to keep data collection limited to what is needed to provide the product, manage accounts and subscriptions, secure the service, and support users.

Information We Collect

Account and profile information

If you create an account, sign in, contact us, or subscribe to updates, we may collect:

• Your name
• Your email address
• Your authentication provider and account identifiers
• Information you send us in support or contact requests

Subscription and billing information

If you purchase a paid plan, we may receive and store subscription and billing metadata needed to manage your account, such as:

• Plan and billing status
• Subscription start, renewal, trial, cancellation, or expiration details
• Customer or subscription identifiers returned by our payment provider

We do not store full credit card numbers on CSSVis Lab servers. Payment details are handled by the payment provider shown at checkout.

Website and extension technical information

To operate the service, we may collect or process:

• Browser type, operating system, and app or extension version
• Basic diagnostic and compatibility information
• Account session information
• Website pages you visit on our own domain

Extension inspection data

When you use the CSSVis Lab extension, the extension may process information from the page you choose to inspect, including:

• Current page URL and title
• DOM structure
• CSS rules and computed styles
• Colors, typography, spacing, assets, and component metadata
• User-initiated screenshots, snippets, or exports

Core inspection features are designed to run locally in your browser. We do not send inspected website content or extracted CSS data to our servers as part of the extension's core inspection workflow. The extension may temporarily cache selected page data, generated code, and the current page URL in local browser storage to support previews, exports, and in-session workflows. We do not maintain a persistent browsing history of pages visited across the web, and we do not sell inspected website content or use it for advertising.

How We Use Information

We use information to:

• Create and manage user accounts
• Authenticate users and keep sessions secure
• Provide extension access and sync plan status
• Process subscriptions, renewals, and customer support requests
• Improve compatibility, reliability, and product quality
• Prevent abuse, fraud, and unauthorized access
• Communicate important product, account, or policy updates

What We Do Not Use Data For

We do not sell personal data.

We do not use inspected website content for advertising or ad targeting.

We do not collect health information, personal communications, or precise location information as part of the core CSSVis Lab product.

Third-Party Services

We may use trusted third-party providers to operate parts of the service, including:

• Authentication providers such as Google or GitHub, if you choose social sign-in
• Payment providers such as Creem for checkout, billing, and subscription management
• Email and support providers for transactional emails and replies
• Hosting, storage, and infrastructure providers needed to run the service

These providers only receive the information required to perform their services for CSSVis Lab.

Cookies and Session Technologies

Our website may use cookies or similar session technologies for:

• Sign-in and authentication
• Security and fraud prevention
• Saving essential site preferences

We do not use cookies to sell personal data.

Data Retention

We keep personal data only for as long as it is reasonably necessary to:

• Provide the service
• Maintain account and subscription records
• Meet legal, tax, accounting, or security obligations
• Resolve support issues and enforce our terms

Extension data stored locally in your browser may remain there until you remove it, clear browser storage, or uninstall the extension.

Data Sharing

We may share limited information only:

• With service providers acting on our behalf
• When required by law, regulation, or legal process
• To protect CSSVis Lab, our users, or the public from fraud, abuse, or security threats
• In connection with a business transfer such as a merger, acquisition, or asset sale

Security

We use reasonable technical and organizational safeguards to protect personal information. However, no method of transmission over the Internet or method of electronic storage is completely secure.

Your Choices

You can:

• Update certain account information in your account settings
• Disconnect or stop using the extension at any time
• Clear locally stored extension data through your browser
• Contact us to request account-related assistance

Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date on this page.
