Privacy Policy

This policy describes the data that Old Days (the game, the website and the game servers, together "the Service") actually collects. We only collect what is needed to make the game playable, prevent cheating and fix bugs. We do not sell data or use it for advertising.

This is a translation for reference only. If there's any discrepancy, the Traditional Chinese version prevails. 繁體中文 →

1. What we collect

When you sign in to the game or website with Steam, or link Discord on the website, we have the following data:

  • Steam account data: SteamID, Steam name and avatar (used to sign in).
  • Discord account data (only if you link Discord): Discord ID, name, avatar, and your Discord-verified email address (used to help you recover your account if something goes wrong; it is passed to the game server to match old accounts and is never made public).
  • Other data you authorize us to read when linking Discord: other accounts connected to your Discord (e.g. Steam), your nickname, roles, join date and boost date in the official Discord server, and your Discord account's locale, whether two-factor authentication is on, Nitro type, badges, profile banner and accent color.
  • Game data: your in-game name, character appearance, KZ records and the key-input logs used for replays, long-jump records, your inventory / level / class / builds in the world, and achievement and check-in records.
  • Connection and security logs: the IP address you connect from, sign-in times, room server connection logs, and records of reports and penalties (used to prevent cheating and deal with rule violations).
  • Crash reports: if the game crashes, it sends a crash log the next time you start it (operating system version, graphics card model, game version and the game log from before the crash). Login credentials are masked first, and no files from your computer are included.
  • Chat and voice: text chat is relayed through the server to other players and may remain in server logs. Voice is only relayed in real time; it is not recorded or saved.
  • Website browsing: only after you click "Accept" on the website do we use Google Analytics to count page views (which pages are viewed and roughly where visitors come from; it stores cookies in your browser). You can use the site normally if you decline, and you can change your choice anytime with "Cookie settings" in the footer. We also use Vercel Analytics to count traffic; it uses no cookies and records no personal data. Your login status is kept in a cookie.
  • Abuse-prevention records: the website temporarily records IP addresses to limit how many requests one source can make in a short time; these records are deleted automatically when the time window ends.

2. What we use it for

  • Signing you in, saving your game progress, and showing leaderboards and profiles.
  • Preventing cheating and dealing with rule violations (e.g. verifying records by replay, kicking or banning people who ruin the game).
  • Finding the causes of crashes and bugs, and improving the game.
  • Announcing important changes (e.g. maintenance, rule changes).

3. Who can see it

Names, avatars, records and character appearances on the leaderboards and profiles are public. Email addresses, IP addresses and crash logs are not public and can only be seen by the people who operate the Service.

To provide the Service, data is stored with these providers: Steam (login), Discord (account linking), Vercel (website hosting and traffic statistics), MongoDB (database), Cloudflare (downloads and networking), and Google Analytics (page-view statistics). We do not give data to anyone else unless required by law.

4. How long we keep it

Game progress is kept for as long as your account exists. Connection logs and crash logs are kept for up to 1 year; penalty records are kept until 1 year after the penalty ends (to prevent repeat offenses on a new account). After you request deletion of your account, your personal data is deleted within 30 days and your leaderboard records are made anonymous.

5. Your rights

Under Taiwan's Personal Data Protection Act, you can ask to view, copy, correct, stop the use of, or delete your personal data. Send a direct message to an admin on the official Discord, or email Icery@Icery.tw, and we will handle it within 30 days.

If you are under 18, please have a parent or guardian read this policy before using the Service.

6. Changes to this policy

When the way we collect data changes, we will update this page and announce it on the official Discord. The date of the last update is shown at the top of the page.

Questions? Head to the official Discord and DM an admin.
