How Fenrir works
Fenrir runs on your computer and plays the game for you in an emulator. Here we explain in plain words what it does, what it doesn't do, and what goes online.
It sees the screen and taps
Fenrir takes a screenshot of the game in your emulator, uses screen recognition to understand what is where, and taps the emulator, just like someone looking at the screen and playing with a finger. It does not modify the game's files.
It verifies every step
After each action it checks the result on screen again: after sending an army it sees the army counter go up, after collecting troops it sees the bubble disappear. An action that isn't verified doesn't count as done.
No gem spending, no purchases
Before every tap it looks at the screen: it never presses a button that shows a price or a gem icon, and it never buys anything from the shop. Jobs that use items, like speedups, are off by default; if you turn one on, you're asked for a daily limit.
It doesn't attack
It never attacks players, cities or forts, never teleports and never activates a shield. If your armies are attacked (the screen flashes red), it calls the armies that are out back to the city and notifies you; you can choose to have it just stop instead.
It stops at verification
If the game shows a verification (captcha) screen, Fenrir doesn't try to solve it and doesn't tap anywhere. It stops and notifies you with a Windows notification (and on your phone if you turned that on); once you solve it, it carries on where it left off.
It waits while you play
If you touch the emulator yourself, the bot pauses on that emulator and resumes a few minutes after you stop. If you log in from your phone, it leaves the account alone; when the time you chose in the panel is up, it takes the account back, or never does if you prefer.
No password needed
Fenrir works with the game that is already open in your emulator. It never asks for or stores your game account's password.
It recovers when stuck
When it meets a window it doesn't recognize, it first tries to close it; if the screen doesn't change for a long time, it restarts the game, and if needed the emulator. If it still can't fix things, it stops and notifies you.
What goes online while the bot runs?
Everything Fenrir sends over the internet is listed below. All the details are in the privacy policy.
| License check | Once a day: your license key, a fingerprint of your computer ID and the version. If the internet goes down, Fenrir keeps working for 72 hours after the last check. |
|---|---|
| Running signal | Every 5 minutes while the panel is open, and when the bot starts or stops: license, a fingerprint of your computer ID, version, game, and whether the bot is running. |
| Update check | Every 30 minutes the list of new versions is read; when an update downloads, your license key and computer fingerprint are sent. If automatic updates are off, this check doesn't happen while the bot runs. |
| Phone notifications (optional) | Only if you turn them on: when something happens, like getting stuck, an attack or a verification, a short message goes to Discord or Telegram. No coordinates or screenshots are sent; your player name is included only if you enable it. |
| Data sharing (optional) | Off by default. If you turn it on, the game parts of the screen are shared to improve screen recognition (chat and names are blurred); while the bot runs they are only queued on your computer, and they are sent when the bot stops. |
With data sharing off, nothing from the game is sent: your game account, coordinates and screenshots stay on your computer. A support ticket is sent only when you press "Open support ticket".
