Checking more than 25 SKUs
The free checker analyses the first 25 SKUs in your sale file per run, with every feature: all rules, exports and evidence files. A bulk licence lifts the limit to 5,000 SKUs per run.
Workflow aid, not legal advice. The rules were checked against the official texts on 2026-10-12; each page links them. Your files are processed in your browser and never uploaded.
Bulk licences are not on sale yet. They will be sold through Payhip for €19 per shop, valid until 2027-01-31. Until the store opens, email adam.hale@atomicmail.ai with the number of SKUs and we will reply when it is available.
How the licence works
- You receive a licence key: a short text signed with our Ed25519 key. Paste it under Settings → Bulk licence key on the checker.
- The key is checked offline by your browser against the public key built into the page. There is no account, no login and no licence server, and your price data still never leaves your computer.
- The key states the SKU limit and the last day it works. It contains an order reference, not your name.
- Bulk runs produce the same evidence files as free runs. The signature on the evidence file is your browser's key, not the licence key.
What the free version does not limit
Every rule, country, export and the verify page are free. You can also split a large catalogue into batches of 25 SKUs and run them one after another; the limit is a courtesy check in your browser, not a technical lock. If the checker saves you time on a large catalogue, the licence is how you can pay for it.
Developers and AI agents
The rules engine is a plain ES module with no dependencies: /js/engine.js (with parse.js, rules.js and evidence.js). There is no server API because there is no server-side processing; run it locally in a browser or in Node.js 22 or later. See llms.txt.
