What a license is
A Nitro license is a right to run the Nitro extension on one store domain, for as long as that store runs it. It is bought once. It does not expire, there is nothing to renew, and there is no recurring charge of any kind.
The license covers every system the extension ships. There are no tiers, no add-ons and no features held back for a higher plan.
The extension is licensed, not sold. You may install it on the store the license covers, modify it for that store's own use, and keep running it indefinitely. You may not redistribute it, resell it, or publish its source.
Domains and multi-store
A license is bound to a storefront domain, not to an OpenCart installation. If one install serves several storefront domains, each of those domains needs its own license. Three storefronts on one codebase means three licenses.
Unlicensed domains on a multi-store install are simply not accelerated; the licensed ones keep running normally. Nitro reports every configured storefront domain when it checks in, and answers for each of them separately.
A license can only be issued to a public, resolvable domain. Development hostnames —
localhost, .test, .local, .ddev.site,
loopback and private-range addresses, and bare IP addresses — are refused: they identify
nothing, and a license against one would cover every machine that uses it.
The trial
Installing the extension starts a 7-day trial for that store domain automatically. There is no account to create, nothing to enter and no card.
Each store domain gets one trial every 30 days, counted from the day the trial started. Uninstalling and reinstalling does not bring the next one forward, and neither does using a different email address — the trial is recorded against the domain, and that record is what the next one is measured from. Once the 30 days have passed, installing the extension again starts a fresh 7-day trial.
When the trial ends, the extension stops accelerating that store until a license exists for it, or until the next trial comes round. Nothing else happens: OpenCart goes back to serving every page itself, exactly as it did before Nitro was installed. Your data, your settings and your store are untouched.
Price and payment
A license costs what this site quotes at the time you buy it, and that price is what you pay for that license — a later change to the published price does not apply backwards, in either direction. Prices are in euro.
You pay through PayPal and the license is issued automatically to the domain and the address you gave; the purchase page explains exactly how that works. If you would rather not use PayPal, email us and we will invoice you. What happens if you buy and it does not work for you is on the refunds page.
Revocation
A license may be revoked for abuse. That means sharing or reselling it, using one license to cover domains it was not issued for, redistributing the extension, or attacking the license API — not, ever, for asking too many support questions or for disagreeing with us.
A revoked license stops being reported as valid, and the extension stops accelerating the store the way it does when a trial ends. We will tell you why.
Warranty and liability
We warrant that the extension does what this site says it does. That is the whole of the warranty: no promise of a particular speed, a particular score, a particular ranking or a particular revenue, because those depend on your host, your theme, your catalogue and your traffic, and we cannot see any of them.
Nitro is built to fail open. If any part of it errors, the request continues as though the extension were not installed — a fault in Nitro falls through to stock OpenCart behaviour rather than taking a store down. That is a design principle and it is tested, and it is the reason the practical risk of installing it is low. It is not a promise that no fault can ever have a consequence.
Keep backups, and try new versions on a staging copy first. Our liability for any claim relating to the extension is limited to what you paid for the license it concerns.
Changes
If these terms change, the date at the top of this page changes with them. A change does not alter what a license you already hold covers: one store domain, lifetime, no renewal.
