Privacy Policy
Last updated: April 2026. This policy describes how FreeDynamicQRCode collects, uses, and protects your data.
Data We Collect
When you scan a dynamic QR code hosted on vsn.to, we collect: a one-way SHA-256 hash of your IP address (not the IP address itself), your approximate country derived from the IP before hashing, your device type (mobile, desktop, or tablet), operating system, browser, and the time of the scan. We cannot reverse the hash to recover your IP address.
Cookies
We use a single httpOnly session cookie to keep you signed in after you verify your email. This cookie does not track you across other websites. It expires after 30 days or when you sign out. We do not use advertising cookies or third-party tracking cookies.
Data Retention
Scan event data is retained for 90 days. Account data (email, name) is retained until you delete your account. QR codes and their associated scan history are deleted within 30 days of account deletion.
Your Rights (GDPR)
If you are in the European Economic Area, you have the right to access, rectify, or erase your personal data. Because IP addresses are stored only as irreversible hashes, we cannot identify or delete scan records associated with your IP. To exercise your rights, visit our Contact page.
