# QR code tracking and privacy: what you can measure responsibly

> A dynamic QR code can count scans, unique visitors per day, approximate country and city, and device type. None of that requires storing IP addresses or personal data. Kizmo keeps only a salted, day-scoped hash for unique counts and never stores raw IPs.

## What scan analytics can tell you

- **How many times** each code was scanned, by day.
- **Unique visitors** per day.
- **Where**, at the level of country and city (from the network, not GPS).
- **Which devices**: iOS, Android or desktop.

## What they cannot tell you

Who scanned. A QR scan carries no name, email or phone number, and it should stay that way.

## How Kizmo handles scan data

- No raw IP addresses are stored.
- Unique counts use a salted hash that changes every day, so visitors cannot be tracked across days or codes.
- No cookies are set on the redirect.
- Scan data is used only to show you your own statistics and to detect tampering.
