Source code licence

A non-exclusive right to use the source code, perpetually and worldwide. Once the invoice is paid this right is yours for good: it does not expire, does not need renewal and is not revoked, provided you observe the conditions below.

The right to modify the code in any way: extend it, cut it down, rewrite it, combine it with your own code. The modified version belongs to you as regards your changes.

The right to run the code in an unlimited number of your own projects and on an unlimited number of servers, whether owned or rented.

The right to hand the code to a contractor working on your project, provided they use it only for you and on the same terms.

Sell, give away or otherwise transfer the source code as a product in its own right — whole or in substantial part. This is the single prohibition the whole document exists for: the product is sold to many buyers, and every resale devalues everyone else’s purchase.

Publish the code openly — in a public repository, as part of an open project, or in teaching material with the sources attached.

Grant sublicences, that is, pass the rights under this document to third parties. The rights belong to the buyer, not to whomever the buyer chooses to pass them on to.

Remove authorship notices from files where they are present.

None of this prevents you from selling a product built on this code: a website, app or service with the code running inside it is your product and yours to dispose of. The line is simple: your customer pays you for what the code does, not for the code itself.

The licence is granted to one legal entity or individual entrepreneur — the one the invoice is issued to. Subsidiaries and affiliates count as separate entities and need their own licence.

The number of projects within your company is unlimited. So is the number of external clients you build projects for using this code — provided you sell them a finished product or work, not the code itself.

The code includes open-source libraries and components. This licence does not extend to them — their own terms apply, and we are not entitled to change them.

A list of such components with their licences is supplied with the code. Where one of them places obligations on you as a distributor, this is noted separately in the list.

The complete source code, with no parts removed and no limiters requiring contact with our servers.

Documentation: how to run it, how to configure it, what it consists of, where to change what.

A list of external dependencies and services the code needs in order to work, with paid ones marked as such.

The catalogue contains no code that requires a subscription to anything from DevUz Studio. A purchased product keeps working even if the studio ceases to exist.

You receive the version of the product current on the day of payment. Subsequent updates are not included in the price unless the invoice says otherwise.

Defects in the delivered version are fixed free of charge within 30 calendar days of delivery. This means defects in the code, not adaptations to your requirements.

Adaptation to your requirements is separate work under a separate invoice. This is not a refusal to help: the price is calculated on the basis that the code is delivered as is, and folding an unknown amount of adaptation into it would raise the price for everyone.

We warrant that the code works as described in its documentation and that we are entitled to supply it to you.

We do not warrant that the code will suit your particular task if it differs from the one described, nor that it will run in an environment differing from the one described in the documentation. That is precisely why a demonstration is available before purchase — look at it.

We are not liable for losses arising from use of the code beyond the amount you paid for it.

The right to use the code terminates only if section 2 is breached — that is, if the code is sold, published or sublicensed. In that case the licence ends at the moment of breach and money paid is not refunded.

No other circumstance — support ending, the catalogue changing, the studio ceasing to operate — affects your right to use code you have already bought.
