Terms
Short, because this is a portfolio and a place I write, not a product with accounts and subscriptions.
Who you are dealing with
This site belongs to Diogo Ferreira, an independent designer and developer working from Luxembourg. There is no company behind it and no team: one person writes everything here and answers everything sent through it, at df@diogoferreira.com.
Using what is published here
The writing, the design and the code of this site are mine. Quote it, argue with it in public, and send it to whoever you like, as long as you say where it came from and link back. Do not republish an article whole as if it were yours, and do not feed the site to a tool whose purpose is to reproduce it under another name.
Client work shown in the projects section belongs to the clients. The brands, logos and screenshots are theirs, shown here as a record of what I built.
The numbers on this site
Where I publish a measurement, it was measured, the method is stated next to it, and the date it was taken is stated too. Sites change after I hand them over, so a number true in September may not be true when you read it. Where I quote somebody else's study I name the source, and where that source sells something related to its own findings I say so.
None of it is advice about your particular site. Reading an article here does not make me your consultant, and I am not liable for what happens if you apply something from it without checking whether it fits your case.
Sending the form
The enquiry form starts a conversation and nothing more. It is not an order, it does not reserve time in my calendar, and it does not commit either of us to anything. Work begins only when there is a written proposal naming the scope, the price and the dates, and we have both agreed to it. That document governs the project, and where it disagrees with this page, it wins.
Links out
I link to other people's work throughout the writing, including to companies I disagree with. A link is a reference, not an endorsement, and I have no control over what those pages say after I link them.
Law
These terms are governed by Luxembourg law, and the courts of Luxembourg are the ones that would hear any dispute about this site. If a project is governed by its own agreement, that agreement decides instead.
