Privacy policy
Last updated: September 28, 2026
This page explains what data Liosaurus processes, why, for how long, and how to exercise your rights. Liosaurus is a free, unofficial community website for Pet Simulator 99.
1. Data controller
The site is run by a private individual under the pseudonym “Lio”. For any question about your data: lio81230 (Discord).
2. Data we process
2.1 Server logs
Like any website, the server records each request: IP address, date and time, requested page and browser. Purpose: security and troubleshooting. Legal basis: legitimate interest. Retention: 14 days, then automatically deleted.
2.2 Audience measurement
The site uses Umami, an analytics tool hosted on the same server as the site. It sets no cookies, does not store your IP address, and only produces anonymous statistics: page views, referring site, country and device type. No data is shared with third parties. If your browser sends a Do Not Track signal, you are not counted. You can also opt out here:
2.3 Inventory page (BigGames login)
If you log in with your BIG Games account to view your inventory, the site receives an access token, your Roblox user ID and your username. They are stored in a secure cookie on your device, valid for up to 30 days, and are only used to display your inventory and booth. The server also keeps a record of the login (username, Roblox ID, date) for 90 days for security and troubleshooting. Legal basis: performance of the service you request.

2.4 Hatch tracking on Discord
If you link your account with a code obtained on Discord, the server stores your Discord ID, your Roblox ID and username (or the name you chose), the access token and the connection date, up to five accounts per Discord member. This data is only used to post your hatches on the relevant Discord server. Legal basis: performance of the service you request. The token stops working after 30 days at most, and a new authorization for the same Roblox account cancels the previous one. You can request deletion of this data at any time.
2.5 Public player data
Leaderboards, clan and player pages, and share images display public data from the official BIG Games and Roblox APIs: username, ID, avatar, game statistics, clan and competition points. The server caches this data and keeps history to show how it changes over time. Legal basis: legitimate interest, to provide community tools built on data made public by the game publisher. You can object: contact us with your Roblox username and we will remove you from display.
2.6 Preferences stored in your browser
Your theme, favorites and recently viewed items are stored only in your browser. They are never sent to the server. You can clear them by deleting this site’s data in your browser.
3. Cookies and local storage
The site uses no advertising cookies and no third-party trackers. Everything below is either strictly necessary for the site to work or results from your own choice: none of it requires consent, which is why the site shows no cookie banner.

|---|---|---|---|
admin_token | cookie | Admin area login (site administrator only) | 24 h |
bg_pkce | cookie | Secures the BigGames login in progress | 5 min |
bg_connect_pkce | cookie | Secures account linking via Discord | 10 min |

umami.disabled | localStorage | Remembers your audience measurement opt-out | until cleared |
4. Content loaded from other sites
Roblox avatars are loaded directly from Roblox’s servers, and flags from flagcdn.com. As with any image hosted elsewhere, these services receive your IP address. They may be located outside the European Union, notably in the United States.
5. Recipients
Your data is never sold or shared for commercial purposes. Only the following have access to it: the site owner; the hosting provider OVH, in France; and BIG Games, which receives the requests made with your token when you use the Inventory page or hatch tracking.
6. Security
The site is served over HTTPS only. Session cookies cannot be read by scripts and are only sent encrypted. Tokens are never displayed publicly.
7. Your rights
Under the GDPR, you have the right to access, rectify, erase, restrict, object to and port your data. To exercise these rights, contact lio81230 (Discord). We reply within one month. If you believe your rights are not respected, you can lodge a complaint with the CNIL or with the data protection authority of your country.
8. Minors
The site is open to everyone. If you are under 15, ask a parent before connecting your BIG Games account.
