Where each fact comes from and how we check it

Where the facts come from

We read each place’s own website and record what it says it offers children: ages, the weekly timetable, prices and the period each one covers, languages, trial sessions and whether a parent must stay.

Addresses, map positions and opening hours may also come from the place’s Google Maps listing. For a sports club, membership of a national federation may come from the list of member clubs the federation publishes.

Each fact is stored with the address of its page, the date of reading and a short quotation in the language of that page. Directories, news articles, booking sites, social networks and reviews are never used as sources.

Source flags

Every source has one of three flags: published by the place (its own website), Google listing (its entry on Google Maps) or federation list (a sports federation’s register of member clubs).

On a place’s page the flag and the reading date stand next to each fact, so you can see where it comes from and how old it is.

Unpublished facts

When the pages we read leave a fact out, the place’s page marks it as not published and the table shows a dash. “Not published” describes our sources; it says nothing about the place.

Missing facts are never guessed. A school year group (such as the lower-school pupils, alsó tagozat) or a birth-year squad is not turned into an age. A price keeps the period the place states; the one calculation made is the ≈ price per session, a course or pass price divided by its sessions.

Class times and opening hours

Times are shown in two columns. Class times: the days and hours of a class, a care session or a camp day, as the place gives them. Opening hours: when the building is open, often taken from the Google listing.

A place can be open while no group for a given age meets. A row that has opening hours and nothing more goes under the dividing line, beneath a heading that says so.

The after-school pages look at weekdays from 16:00 to 18:00, after the school’s own afternoon programme for younger pupils has ended. A class counts when one of its groups starts inside that span; after-school care counts when its hours, extended hours included, cover the span in full.

What the catalogue does not judge

No place, teacher, coach or programme is given a rating, score or rank.
Nobody visits the places; every fact is taken from a published source.
Nobody assesses how well a class is taught, a team is coached or children are looked after.
Whether a group has places left is not followed here; the place can tell you.
Prices appear as published, with their period and date, and are not confirmed with the place.

Corrections from places

If you run a listed place and a fact is wrong, incomplete or out of date, send a correction through the correction form with a link to the page that shows the correct fact.

A correction backed by the place’s own pages goes into the next update and is recorded in the list of changes. A place that has closed keeps its page, marked as closed, and leaves every table.

A place can also ask to be removed: choose “Ask to remove a listed place” in the correction form and give a contact showing that you run it. The place, its page and its records in the data files are removed within a month.

Dates and updates

The sources of every place are read again within 6 months of the previous reading. A price published for a period that has ended stays on the place’s page with that period, and the filters and the summary line ignore it.

How the catalogue is paid for

Places do not pay to be listed, and no payment changes a row or its position in the table.

A place’s page may carry one link to Zartrace, a service connected with this catalogue and marked as such. Clicks on the contact buttons are counted only as totals, with no personal data.

Open data

The whole catalogue can be downloaded as JSON, one record per place, or as CSV, one row per programme. Both files carry every source, flag and date and state their licence.

Areas, distance and the map

Areas are Budapest’s named neighbourhoods (városrészek), each inside one of the city’s districts (kerületek), with a few almost uninhabited ones (forest, port and industrial land) counted with a neighbour, and the towns around the capital. A location is filed under the neighbourhood or town inside whose boundary it stands.

Distance is measured in a straight line from the point you choose to the nearest location and rounded to half a kilometre. Your location is asked for only when you press the button, and it never leaves your browser.
