Privacy Policy

Generic Sinc ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy describes our practices regarding the collection, use, and disclosure of information when you use our website and web application at generic-sinc.tech(the "Service").

By using the Service, you agree to the collection and use of information in accordance with this policy.

We are designed with a privacy-first architecture. All calculations are performed entirely within your browser — your input data is never transmitted to our servers.

We may collect limited information in the following categories:

• Account Data: If you create an account (optional), we store your email address and display name for authentication purposes via Supabase Auth.
• Favorites: If you save tool favorites while logged in, those preferences are stored in our database linked to your user ID.
• Usage Analytics: We may collect anonymous, aggregated usage data (e.g., pages visited, browser type) to improve the Service. No personally identifiable information is included.
• Local Storage: Theme preferences and PWA settings are stored locally on your device and are never sent to any server.

We use essential cookies only for authentication session management. We do not use tracking cookies, advertising cookies, or any third-party marketing trackers.

Local storage is used to save your theme preference (Light, Dark, Glass, or Midnight) and PWA service worker data. This data remains entirely on your device.

The limited information we collect is used exclusively to:

• Provide and maintain the Service
• Authenticate your account and manage sessions
• Sync your saved favorites across devices
• Improve the Service through anonymous analytics
• Respond to your support inquiries

We implement industry-standard security measures to protect your data. Authentication is handled by Supabase, which provides encrypted data storage and secure session tokens. All network communication uses HTTPS/TLS encryption.

However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your personal information, we cannot guarantee its absolute security.

We integrate with the following third-party services:

• Supabase: Authentication and database services. See Supabase Privacy Policy.
• Vercel: Hosting and deployment. See Vercel Privacy Policy.

We do not sell, trade, or rent your personal information to third parties. We do not share your data with advertisers.

If you are accessing the Service from the European Economic Area (EEA), you have certain data protection rights under the General Data Protection Regulation (GDPR). You have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Object to processing of your data
• Request data portability

To exercise any of these rights, please contact us using the information below.

The Service is not directed to individuals under the age of 13. We do not knowingly collect personal information from children under 13. If you become aware that a child has provided us with personal data, please contact us and we will take steps to remove that information.

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective Date" at the top. You are advised to review this Privacy Policy periodically for any changes.
