Why we started

Our founder has worked in a large library system for more than ten years. That’s long enough to see the same problems come up at every branch: public computers that need a reservation system, a cleanup tool and a server to hold them together; staff pulled off the floor when one of them breaks; and the public’s privacy depending on settings nobody has time to check.

A lot of library software is designed a long way from the people who run it on a busy afternoon. Latchwork starts from the other end: what staff and IT teams actually deal with.

For a Carrel pilot or demo, it helps to know:

Whether you’re a library, a school or a university.
How many locations and PCs you have.
Which library system you use, and whether SIP2 is enabled.
What you use today for PC reservations, cleanup between users and printing.

Carrel runs on Windows PCs today. Agents for Mac, ChromeOS and Linux are coming next. Staff and the reservation portal work in any modern browser.

What sets Carrel apart

No Deep Freeze, Reboot Restore Rx or CleanSlate. When a session ends, Carrel deletes that person’s documents, downloads, browser history, cookies and saved passwords, empties the Recycle Bin and clears Windows’ recent files. Then it signs out, and the PC is ready for the next person without a restart. You choose what to keep, such as settings for software in a makerspace.
Clean even after a power cut. If a PC loses power or crashes mid-session, Carrel finishes the cleanup the next time it starts, before anyone can sign in. If it still can’t, staff are told.
Move reservations to another PC. When a PC breaks, transfer its current and upcoming reservations to a replacement. Before anything changes, Carrel lists what the move would do, such as ending someone’s session or breaking a time limit, and waits for you to confirm.
Guest passes designed by you. Add your logo and your own text, pick the barcode type and number format, and check a sample receipt before you print a real one. Print one pass, or a batch for a busy day or a class visit. See what you can change.
Class and event bookings. Reserve a whole lab, a section or a set of PCs for a class. One shared pass works on those PCs, only for that booking, and every session ends together.

People sign in with their library card or student ID and PIN, checked against your library system over SIP2.
Block sign-in when fines are over a threshold you set.
Names come live from your library system and are shown on screen. Carrel never stores them.
Guest passes work even when your library system is down.

Rules and limits

Set rules once for every location, then change only what’s different. Each layer inherits from the one above it, field by field.

Visiting the site

We count visits so we know which pages are useful and how people find us. We use PostHog for this, hosted in the United States, set up so that:

No cookies are set and nothing is stored on your device for analytics. Each page view is counted on its own, so we can’t follow you from one visit to the next.
Your IP address isn’t kept. It’s used only to work out your rough location, such as the state or country, and then discarded.
Do Not Track and Global Privacy Control are respected. If your browser sends either, no analytics are collected at all.
Session recording is off. We don’t record what you type or how you move around a page.

What we see is the page, where you came from (for example a search engine or a link in an email), your browser type and your rough location.
