Rondo is a concert search. Browsing it needs no account and never asks who you are. An account exists so we can write to you when something you asked to be told about happens, and so Rondo can remember what you like.
Your email address, the searches you have saved, the concerts you are tracking, the airport you told us you travel from, and the music and performers you told us you like. If you ask the Rondo team to call you, we also keep the phone number you gave and when suits you. If you write to us from the help panel, we receive the message, the email address you gave for a reply, the page you were on, and, if you allowed recording, a link to the recording of that visit described below. That is the whole list. We never ask for a name, a postal address or a payment method, and Rondo sells nothing, so there is nothing to charge for.
If you sign in with Google, Google tells us the email address on that account and confirms it belongs to you. We ask for nothing else from your Google account — no contacts, no calendar, no files — and we cannot see anything else.
We email you when a saved search matches a newly announced concert, and when a concert you are tracking changes — a new date, a cancellation, tickets going on sale or selling out. Once, a few days after you join, we write to ask whether a member of the team may call you for a few minutes about how Rondo could serve you better; a phone number you give us is used for that call and nothing else. There is no newsletter, no advertising, and we do not sell or share your address or number with anyone.
A handful of services do the work behind Rondo. Supabase stores the database and handles signing in. Vercel runs the site. Resend delivers the emails. Google receives the words you type into the search box — never who typed them — so they can be turned into filters, and handles the sign-in if you choose Google; when Google is unavailable, the same words go to OpenRouter instead, which passes them to the same Google model. Both may process those words in the United States, and Google may keep them to improve its services, so please do not type anything private into the search box. When you type a place to travel from, Open-Meteo turns that place name into coordinates. PostHog counts what is opened and pressed, on European servers. None of them are given anything about you beyond what that job needs.
Rondo keeps a few things in your browser because you asked for them: that you are signed in, the currency and search style you picked, and your recent searches and places. Your chosen text size is remembered for one year, without an account. These preferences stay on your device and are not used to follow you.
PostHog counts which pages are opened and which buttons are pressed. Unless you allow it, it does so without cookies and without knowing it is you — every visit is a stranger. If you press Allow on the question at the foot of the screen, PostHog also sets a cookie, keeps a recording of how your visits moved through the screens — with anything typed into a field hidden from it — and, once you are signed in, ties that record to your account. It is how we find out where Rondo fails people. No advertising cookies, and nothing sold to anyone.
Write to support@rondoevents.com from the address on the account and we delete the account, the saved searches, the tracked concerts and any phone number you gave us. Nothing is kept afterwards. Ask us what we hold about you and we will send it back to you in the same way.
