QRLynx ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our service to create and analyze QR codes.
We collect personal information when you create an account, including your name and email address. If you use OAuth authentication with Google or Microsoft, we receive basic profile information such as your name, email, profile picture, and unique identifier. Authentication tokens are stored securely and used only for account verification. We do not access Google Drive, Microsoft OneDrive, or other services beyond basic profile information unless explicitly authorized.
We automatically collect usage data and analytics including QR code creation and scanning analytics, device information (browser type, operating system), IP address and general location information, usage patterns and feature interactions, and performance and error logs.
For paid subscriptions, payment processing is handled by Stripe, Inc. We do not store your full credit card information on our servers. Stripe may share limited transaction data with us, including transaction IDs, payment status, last four digits of credit card numbers, billing address information, and subscription status.
We use collected information to provide and maintain our service, process payments and manage subscriptions, authenticate users and prevent fraud, generate QR code analytics and insights, communicate with you about your account and our services, improve our service and develop new features, and comply with legal obligations.
We do not sell, trade, or otherwise transfer your personal information to third parties. We share data only with trusted service providers: Stripe for payment processing and subscription management, Google/Microsoft for OAuth authentication services, cloud hosting providers for data storage and service delivery, and analytics providers to improve service and monitor performance.
We may disclose your information if required by law or court order, or to protect our rights, property, or safety.
We implement appropriate technical and organizational security measures to protect your personal information, including data encryption in transit and at rest, secure authentication protocols (OAuth 2.0), regular security audits and updates, access controls and employee training, and secure payment processing through PCI-compliant providers.
We retain your personal information for as long as necessary to provide our services and comply with legal obligations. Account information is retained until account deletion or 3 years of inactivity. QR code data is retained as long as your account is active. Analytics data is retained for up to 2 years for service improvement. Payment records are retained as required by tax and financial regulations.
Depending on your location, you may have rights regarding your personal information including the right to access (request a copy of your personal information), correction (correct inaccurate or incomplete information), erasure (request deletion of your personal information), portability (receive your data in a machine-readable format), restriction (restrict how we process your information), and objection (object to certain types of processing).

Your information may be transferred to and processed in countries other than your own. We ensure appropriate safeguards are in place to protect your information in accordance with applicable data protection laws.
