What we see. What we don't.

A scouting report on your data, not a maze.

Estrelaset is a guessing game, not a surveillance tool. This page is the full picture of how information moves when you play — written so it is easier to finish than a five-clue riddle. If a sentence here ever disagrees with a screen in the app, treat this page as the one that counts and write to us.

The short version

Players do not send information to one another. We do not run a social graph, a public leaderboard feed, or an inbox between fans. We do not ask for your legal name, home address, payment card or date of birth to open a riddle. The most persistent identifier we tolerate is a unique install identifier used so analytics, crash reports and push messages can find the same device again. Display name and avatar live as profile cosmetics on the device.

What this app even is

Estrelaset presents one footballer a day, hidden behind five clues. You type a name, or you ask for the next clue. Points, streaks and a personal collection stay with your play on that device. Clues and the career write-up after a reveal are generated text, not a biography copied from your private life.

What never leaves your guesses as a dossier

A guess is a string of letters: the name you think is behind the jersey. We do not stitch that guess to an email account, a phone book or a government ID. Other users cannot read your misses, your streak or your collection. There is no player-to-player channel, so there is no player-to-player data transfer to explain.

We, Modi Haus LTD, do not operate a warehouse of personal profiles. We do not sell lists of Estrelaset players. We do not build advertising audiences from your football hunches.

The one identifier we tolerate

To keep crash reports useful, to see whether the daily riddle is reaching devices, and to deliver an optional reminder, the app may hold a unique identifier for the install. Think of it as a squad number on a training bib, not a passport. It is there so a push can arrive and so a crash can be grouped. It is not a licence to reconstruct who you are in the rest of your life.

Firebase, the stadium electrician

Estrelaset uses Google Firebase as a third-party service. In this app that means analytics, crash reporting (Crashlytics) and push notifications. Firebase is not “us in another hat”. It is infrastructure run by a third party, with its own notices. Those tools may process device and install signals, app events, crash traces and a messaging token so a reminder can land at the time you chose.

We switch these services on because a daily riddle that silently dies on one phone model helps nobody, and because a reminder you asked for is part of the product. We do not switch them on in order to follow you across unrelated apps.

OpenAI, the clue writer

Clues, career summaries and signature-moment text are generated with OpenAI, a third-party service. The point of that call is simple: produce the day's riddle copy. The payload is the text needed to generate that copy — the riddle brief, not your biography.

When you type a guess, you are sending a player name into the game logic. You are not handing OpenAI a profile, a photo album, a contact list or a location history. No personal dossier rides along with “I think it is Cafu”. If a screen ever asks you to write a free-text note that then goes to generation, understand that only the words you typed travel for that purpose, still without a bundle of identity documents attached.

Machine-written football copy can be sharp and it can be wrong. Treat generated summaries as colour around the riddle, not as a certified archive.

What we refuse to build

No side channel for users to exchange files. No silent harvest of contacts. No requirement that you link a social login before clue one. If a future version grows a feature that needs more than a unique install id, this page will change before the feature pretends it was always so.

Children

Estrelaset is a football trivia toy, not a service aimed at collecting information from children. If you believe a child has given us personal information they should not have, write to the address below and we will treat that as a problem to close, not a lead to keep.

When this page moves

Football rules get rewritten. So do product stacks. If Firebase, OpenAI or the identifier model changes in a way you would notice, we update this report and stamp a new date at the top of the spine.
