Privacy notice

How Lynkarr handles data collected when a QR code or digital card is scanned.

What we record when a code is scanned

When someone scans a dynamic QR code or opens a digital card, we record:

• The time of the scan
• Approximate location — country, region and city — derived from the network connection
• Device type, operating system and browser
• Preferred language
• The referring site, where one exists; scans made straight from a camera app are recorded as “Manual scan”
• A one-way fingerprint used to recognise repeat scans

What we deliberately do not record

• We never store IP addresses. The connecting address is used in memory to derive approximate location and the repeat-visit fingerprint, and is then discarded.
• We do not collect names, email addresses or phone numbers of people who scan a code, unless they choose to submit them through a contact form on a digital card.
• We do not collect GPS or precise location. A scan is an ordinary web request; city level is the limit of what it can reveal.
• We do not track scanners across other websites, and we do not send scan data to third-party analytics services.

Repeat-visit fingerprints

To count unique visitors we compute a salted, one-way hash of the connecting address and browser identifier. The result cannot be reversed to an IP address.

For scans originating in the EEA, the United Kingdom and Switzerland the salt is rotated every 2557 days, and the fingerprints from the closed window are permanently erased. What remains is an anonymous record of the scan itself. Account administrators can extend this behaviour to all traffic by enabling strict privacy mode.

How long data is kept

Aggregated reporting data is retained for up to seven years. Individual scan records are retained for a shorter window and then deleted, with the aggregates they produced retained.

Your rights

Depending on where you live you may have rights to access, correct or erase personal data relating to you. Because we do not store identifying information about people who scan codes, we are usually unable to link a scan record to an individual.
