Who writes these guides, and how they are made

riodejaneiro.app is published by Oleksii Vasylenko Tec Ltda, the same company named in the site footer. We are not a travel agency, we do not sell tours and we take no booking commission — which means no guide here exists to push a product.

The project started from a simple observation: most Rio content organises the city as a list of attractions, when the city actually works by area and by hour of the day. The guides follow that logic, and so does the app being built.

Every guide starts from a practical travel question — where to stay, how to get there, when to go — rather than from a keyword. The structure is always the same: a short answer at the top, thematic sections, frequently asked questions, and a list of official sources at the end.

We prioritise primary sources: Riotur and Rio city hall, MetrôRio, VLT Carioca, BRT Rio, ICMBio and Tijuca National Park, the fire brigade, INMET, INEA, UNESCO, and the attractions' own official sites. Where information depends on those sources, we say so in the text instead of repeating a figure from an old blog.

We do not publish ticket prices, opening hours or event line-ups as though they were permanent facts. That data changes often, and an out-of-date page does more damage than a page telling you to open the official channel before you leave.

We also do not publish 'best of' rankings without context. A good beach, neighbourhood or viewpoint depends on what you are doing that day, the weather and the hour — and that is how the guides present the options.

Each guide shows its last review date at the top, and the same date is published in the page's structured data and in the sitemap. When something changes materially, we revise the whole guide rather than patching a sentence.

If you find something wrong, out of date or confusing, we want to know. Corrections from readers who know the city are worth more than any internal review process.
