Lugister is a Chrome extension that fires an emoji across a friend's screen. This page explains exactly what it collects, what it never touches, and who else sees any of it. It is written to be read, not to be survived.
What Lugister never sees
This is the important part, so it comes first.
- The pages you visit. Lugister does not read, store or send the content of any web page, the URLs you visit, or your browsing history.
- The only code that runs on a page is the piece that draws an incoming emoji. It waits to be handed an emoji and animates it. It cannot read the page around it, and it is only installed at all after you turn on “I'm reachable” and grant permission. Turning that off removes it.
- To know whether a friend's emoji has anywhere to land, Lugister checks whether you have an ordinary web page open. That check happens on your own computer. What leaves it is a yes or no — never which page, or how many.
- Lugister does not sell your data, does not share it with data brokers, and does not use it for advertising or to train any model.
What Lugister does collect
- Your Google account. Signing in is through Google. We receive your Google account id, your email address, your display name and your profile picture. Your name and picture are shown to the other people in your crew, so they know who fired at them. Your email address is not shown to anyone else.
- Your crew. Which crew you are in, and any invite codes you create.
- Your cannon. The skin and accessories you have chosen, so your cannon looks the same on every computer you sign in on.
- Your credits. Your balance, the record of how you earned or spent it, and which items you have unlocked.
- Who you hit. For each day, how many of your shots landed on each person in your crews, and how many of theirs landed on you. Just the counts, seen only by Lugister's administrators.
- Game scores. For each crew, how many penalties you took and scored, how many you faced and saved, and your current and longest run of each. Totals only, seen by the people in that crew. They stay if you leave the crew, hidden from it, and come back if you rejoin; they are deleted with the crew or with your account.
The shots themselves are not kept
A shot is passed from you to your friend and then forgotten. Lugister does not keep a record of what you fired, on which page, or at what time. Restart the server and every shot in flight is simply gone. Two things are counted. How many shots were fired across all of Lugister each day: a single number per day. And, for each day, how many times one person hit another: a count per pair, with no emoji, page or time attached to it, only ever between people who share a crew. Only Lugister's administrators can see these counts, to look into abuse and to understand how Lugister is used. They are kept until you delete your account, which removes yours. A penalty's result is added to the game scores above, for each crew the two of you share; the penalty itself is not kept.
Where it is stored
Your account, crew, cannon and credits live in a database run by Supabase. The service that connects you to your crew runs on Render. This website is hosted by Vercel. Sign-in is handled by Google. Nobody else receives your account information.
Your sign-in session is also kept on your own computer, in the extension's storage, so you are not asked to sign in every time. Signing out removes it.
This website
Visits to lugister.com are measured with Google Analytics, so we can see how many people come and which pages they read. It uses cookies, and Google receives the pages you view, roughly where you are, and what kind of device and browser you use.
The site also uses Microsoft Clarity to see how the pages are used: where people click and scroll, recorded as anonymous session replays, along with the same browser, device and rough location. Clarity sets cookies too, and hides any text you type.
Neither runs on invite links. This is about the website only: the Lugister extension uses neither and sends them nothing, and nothing they measure is linked to your Lugister account. You can block both with any tracker blocker, or Google Analytics alone with Google's opt-out add-on, and the site works the same.
How long we keep it
Until you ask us to delete it. Lugister keeps your account for as long as you use it, and deletes it when you tell us to.
Deleting your account
Email uselugister@gmail.com from the address you signed in with, and we will delete your account, your crew membership, your cannon and your credits. You can leave a crew at any time from the extension itself, which removes you from it immediately.
Children
Lugister is not intended for children under 13, and we do not knowingly collect anything from them.
Changes
If what Lugister collects ever changes, this page changes with it, and the date at the top changes too.
