# LinkShift

> A QR code you print once. Where it points follows a schedule you set: windows, repeating hours, days of the week, priority, and a fallback. For menus, badges, packaging, signage — anything where ink is permanent and the destination isn't.

- [LinkShift — a QR code you print once](https://linkshift.co/) — LinkShift is a QR code for things you can't reprint. Put it on the menu, the badge, the box, the sign. Where it points follows a schedule you set, and you never print again.
- [Privacy](https://linkshift.co/privacy/) — What LinkShift records when a code is scanned, what it never records, and what it keeps about account holders.
- [Where a LinkShift code belongs](https://linkshift.co/use-cases/) — Menus, badges, packaging, signage, posters. Anywhere a link gets printed and then has to mean something different later.

## Facts
- The QR encodes a permanent short link; rules decide the destination at scan time.
- Rules: bounded or unbounded windows, daily or weekly recurrence, midnight-crossing windows, priority ordering, a non-empty fallback.
- Every scan is a 302. Destinations are never cached.
- Scans record device, country, referrer and the active rule. The IP address is discarded, never stored.
- Custom domains are verified by a TXT and a CNAME record; an unverified domain never reaches a printed code.
- Archived codes show a retired message; codes are never silently deleted.
