How it works
A Chrome extension is a small program that runs inside your browser and adds something to the pages you already use. Nothing else gets installed and none of your programs change.
Installation
Every one of our extensions is in the official Chrome Web Store. Click Add to Chrome, confirm, and you're done. It works in Chrome, Edge, Brave, Opera and Vivaldi. An extension only shows up on the sites it is built for — Prověř firmu reacts to a selected company ID, Allegro Cockpit only on allegro.pl and allegro.cz.
Free and Pro
The basic features of every extension are free, with no sign-up, for good. The Pro version adds what takes extra work: monitoring with alerts in Chrome, bulk checks, export, switching between clients. Each product page says what is where.
Payment
- 1
Pay by card
On the product page. A VAT invoice arrives by e-mail.
- 2
Receive your key
By e-mail within a minute. Paste it into the extension's settings and the Pro features unlock.
- 3
Cancel any time
With the link in the e-mail or on the invoice. No phone call, no notice period. The free features stay free.
Updates
Chrome downloads updates by itself. When a site an extension works on changes its layout, our automatic morning test notices and we ship the fix the same day. You don't need to do anything.
Support
Every extension has an FAQ. For anything else, write to us through the form on the product page; we reply by the next working day. We have no phone line and no sales team — that's why the prices are what they are.
