Privacy: Eclipse for Hero Wars

Last updated 4 November 2026.

Eclipse for Hero Wars is the browser extension of Eclipse (www.hwa-eclipse.com), a web companion for guilds playing Hero Wars: Alliance. This page says what the extension reads, what it sends, and where it goes. It is not made by or affiliated with Nexters, the maker of Hero Wars.

Where it runs

It runs only on the Hero Wars web game at www.hero-wars-alliance.com, and talks only to Eclipse at www.hwa-eclipse.com. It does nothing on any other website and does not read your browsing.

What it reads

Inside the game’s page it reads the game’s own requests and replies, as the game makes them, to learn your heroes, titans and talismans, your quests and emerald balance, the state of the Eternal Frontier, Guild Dungeon and talisman screens, and your arena battles.

What it sends to Eclipse

Nothing at all until you paste your personal Eclipse token into the extension. With it:
  • Your own heroes, titans and talismans (their levels, stats and power), from the game’s sign-in data and from the guild training replays you open. Only your side of a replay is kept.
  • If you switch on an auto-player (some guilds also ask a guild admin to approve it): what Eclipse needs to plan your next fight (your teams, your level, the enemy teams), and each fight’s result. While you play a Frontier level yourself, the game’s replies for that level’s battles. With each Frontier Auto Battle it sends, the extension also reports whether the game’s tab was visible, whether its window was in front, how long the tab was hidden since the last one, and how long its last pause took. It does not report what else you were using.
  • Your arena battles, including ones you fight by hand: both teams’ heroes, powers and talismans, and the result. This includes details of the other player: their game account id, their clan’s name and their heroes’ stats. Eclipse keeps these only if you have switched on arena attacks, and uses them to choose counters. It is also asked before each extra arena attempt is bought, and checks the daily limit you set.
  • When you run a daily: which daily it is, so Eclipse can check it is allowed. Nothing is stored from this. Mission gifts also asks Eclipse which missions to raid.
  • Your game account id, with the requests above, so Eclipse can check the game is signed in to your own account.
  • Changes you make on the extension’s own Settings page.
  • Each Eternal Frontier Auto Battle sent from the game page by something other than the extension, such as the game’s own button or another tool: the teams sent, the level and its enemy teams, and the result. Eclipse learns which teams win from these.
  • Once each time the game loads, the few account details that decide which game shops you are offered (your team level and its cap, region, account flags, server and time zone), the game’s test groups for your account, and the list of shops the game asks for. This check never includes your name, currencies or account id.
  • If you switch on talisman rerolling: a request to start each reroll run.
  • The extension’s version number, so Eclipse can turn away an outdated copy.

What it never sends

Your Hero Wars login, password, session or the game’s authorisation details, your Discord account details, or anything from outside the game’s page. They never leave your browser.

What it sends to the game

Only after you press a button in the extension (Start, Run, Run all free or Refresh heroes): the game’s own commands, sent from your account as if you had pressed the buttons yourself. They include Auto Battle, saving a team, choosing a dungeon door, rolling and saving a talisman, arena and Grand Arena attacks, buying arena attempts, and daily chores such as expeditions, raids, opening chests and claiming quests. A run you started can carry on by itself after the extension reloads the game page.

Some of these spend your game resources: talisman cubes, energy, and emeralds (the Wheel of Fortune, extra arena attempts within your daily limit, and the Tower if you switch it on). Automating the game breaks Hero Wars’ terms of service, and the risk to your account is yours. Eclipse asks you to accept it before any auto-player can be switched on; for the other dailies, pressing the button is your choice.

What it keeps on your computer

Your Eclipse token and the extension’s own settings, in Chrome’s storage for the extension. Removing the extension deletes them.

How Eclipse uses it

To show your heroes to you and your guild on Eclipse, to plan tests and war attacks with them, to plan the auto-players’ fights, and to learn which teams win for other members. It is stored on Eclipse’s own server. It is not sold, not used for advertising, and not shared with anyone outside Eclipse. The use of information received from the extension adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Stopping and deleting

Revoke your token on your Eclipse Settings page and the extension can send nothing more; switch an auto-player off there and it stops at once. To have the data the extension sent deleted, ask your guild’s admins on Discord.

Your account on this website

You sign in with Discord. Discord tells us your account id, name, avatar and email address, and we store them with the tokens Discord issues for your sign-in. We ask Discord whether you hold the Member role in the guilds that use Eclipse, to decide whether to show you your guild; we do not read or keep your list of servers. None of this is sold or shared. If you are not in a guild that uses Eclipse, you can delete your account on your account page, which removes all of it. If you are, ask your guild’s admins.

If this page changes, the date at the top changes with it.
