Imperatle

Privacy Policy

Last updated: October 7, 2026

Imperatle is a free daily game made by one person, Ventura, a developer based in Brazil, who is responsible for the data described here. The game collects as little as it can: you don't need an account, and nothing here is used for advertising or sold.

What is collected

  • A random identifier stored in a cookie (imperatle_aid) the first time you guess. It isn't linked to your name, e-mail or device; it only lets the server count your attempts and keep your statistics.
  • Your games: the date, how many attempts you used and whether you got it right, linked to that identifier.
  • Your progress of the day, saved in your own browser (local storage) so the board survives a page reload. It never leaves your device.
  • Feedback you send: the message, its type, the site language and, only if you fill it in, your e-mail address.
  • Your IP address, used for a few minutes to limit how many guesses and messages can be sent in a row. It isn't stored by the game, although the hosting providers below may keep it in their technical logs.
  • Page views, counted by Vercel Web Analytics without cookies and without identifying you.

Why

To run the game (count attempts fairly, show your statistics and everyone's results of the day), to protect it against abuse, to read and answer feedback, and to understand how many people play. The legal basis is the legitimate interest in providing and securing the game, and your consent for the optional e-mail in the feedback form.

Who else handles the data

The game relies on these providers, each under its own privacy terms:

  • Vercel (website hosting and page analytics), United States.
  • Microsoft Azure (game server).
  • Neon (database).
  • Resend (forwards feedback messages by e-mail), United States.

How long it is kept

Game records are kept while the game exists, since they make up your statistics and the daily results. Feedback is kept for as long as it's needed to handle it. The cookie expires one year after it is created.

Your rights

Under Brazil's LGPD and, where it applies, the European GDPR, you can ask to access, correct or delete your data, or object to its use. Send the request through the Feedback form in the menu. Deleting your browser's cookies and site data also cuts the link between you and your game history.

Children

The game isn't directed at children under 13 and doesn't knowingly collect their data.

Changes

This policy will change when new features arrive (accounts and support, for example). The date at the top shows the latest version.

How to play

Find out which empire is on the map, shown at the height of its expansion. You have 7 attempts.

Type an empire's name, pick it from the list and click Guess (or press Enter twice).

Each wrong guess compares the empire you picked with the one on the map:

  • ✕not this one
  • ▲the map's empire was larger in area, or lasted longer
  • ▼the map's empire was smaller in area, or didn't last as long
  • ≈both are about the same (within 10%)

Each miss also unlocks new clues about the map's empire, right under your guess.

Hover or tap a clue, or the area and duration, to see what it means.

A new empire every day.

About

Imperatle is a daily guessing game. Every day, a different historical empire appears on the map, at the height of its expansion, and you try to figure out which one it is.

A note on empires

The game is only about territorial extent and facts. Showing how far an empire reached isn't celebrating conquest: many of these empires grew through war, colonization and the suffering of other peoples.

Sources and accuracy

Historical borders are adapted from Cliopatria (Bennett et al., Seshat Global History Databank), under CC BY 4.0, simplified and clipped to today's coastline. The world map comes from Natural Earth (public domain). Historical dates, areas and borders are approximations, and sources often disagree.
