Sell it, keep the money
Apache-2.0. Charge what you like, to as many shops as you like, and keep all of it. No revenue share, no licence fee, no registration, and no conversation with us required.
InkDrop.
A local, QR-first file counter for print and photocopy shops. A customer scans the shop sign, joins the shop Wi-Fi, and uploads files in an ordinary browser; the shop computer receives them in an operator queue. Scanned work goes back through short-lived pickup links and QR codes.
No app to install, no customer account, no cloud relay, and nothing printed automatically. The files never leave the shop’s own network.
Open source under Apache-2.0 — clone it or browse the repo:
Rename it, change it
Ship it as your own product under your own name. Add features, remove ours, and keep your modifications private — there is no copyleft obligation to publish what you change.
What the licence asks
Two things, both standard: ship the LICENSE with it, and keep the NOTICE file so the attribution travels with the code. It does not require our name in your interface, your packaging, or your marketing.
What we ask, and do not require
A line such as “Built on InkDrop by ClassEve” somewhere a curious person can find it — an About screen, a footer, a version string. It is a request, not a condition. Removing it breaks nothing and we will not chase you.
Runs on the shop’s own network
The shop machine serves the upload page over its own Wi-Fi. Customer files reach the operator directly, without passing through anyone else’s server.
No app, no account
The customer scans a QR code and uses the browser already on their phone. Nothing to install, nothing to sign up for, nothing to remember.
Pickups expire
Scanned work returns through short-lived pickup links and QR codes rather than staying available indefinitely.
Limits, stated plainly
It counts and moves files. It does not print automatically and it does not convert Office formats — a shop still opens files in whatever it already uses.
The full source is on GitHub under Apache-2.0: Classevelabs/InkDrop. Clone it, build it, sell it — nothing else is required of you.
Written in Go, with a Windows installer produced by Inno Setup and a plain binary on Linux. The builds ClassEve published carry a TOTP activation gate, because that is how the product was originally sold; the gate is inert when no master secret is compiled in, so a build made from source is fully functional with no activation step and no call home. You do not need anything from us to produce a sellable binary.
