This Privacy Policy explains how we collect, use, store, and protect your information when you use our application at measurelab.app (and related domains). By using MeasureLab, you agree to this policy.

2. Information We Collect

We collect information necessary to provide and improve the service:

Account data: When you register or sign in (email/password or Google), we store your account identifier, email address, and optionally your name and profile picture if provided by Google Sign-In.
Profile data: We store a minimal profile (e.g. subscription role) linked to your account to deliver the correct features.
Measurement and project data: If you use the application while signed in, we may store projects, images (including uploads and annotations), and measurement data you create, so you can access them across sessions.
Usage and analytics: When you consent to cookies, we use analytics (e.g. Google Analytics) to understand how the application is used (pages visited, general usage patterns). This does not include personally identifiable measurement content.
Technical data: We may log technical information such as IP address, browser type, and device information for security and operational purposes.

3. How We Use Your Information

We use the information we collect to: provide and maintain the application; enable sign-in and account management; store and sync your projects and measurements; improve our product and fix issues; analyze usage (with your consent) to improve the experience; and comply with legal obligations. We do not sell your personal data to third parties.

4. Third-Party Services

MeasureLab relies on the following third-party services that may process your data:

Supabase: We use Supabase for authentication (email/password and Google OAuth) and to store your account, profile, project, and image data. Their privacy practices apply to this processing.
Google: If you sign in with Google, Google processes your sign-in and may share your email, name, and profile picture with us as described in Google's privacy policy and consent screen.
Google Analytics: If you accept cookies, we may use Google Analytics to analyze usage. You can control this via our cookie banner and your browser or Google settings.

5. Cookies and Local Storage

We use cookies and local storage to: keep you signed in; remember your preferences (e.g. theme or cookie consent); and, with your consent, for analytics. You can decline non-essential cookies via our cookie banner. Essential cookies are required for authentication and core functionality.
