Privacy Policy

Game: Doomsday Guardians (末日守护) — a Facebook Instant Game
This policy explains what information the game accesses, how it is used, and your choices regarding your data.

1. Information We Access

The game runs inside the Facebook / Messenger platform through the Facebook Instant Games SDK (FBInstant). In that environment, the game accesses only the following information:

We do not collect your real name, email address, phone number, physical address, payment information, or precise location. The game does not use any third-party analytics or advertising tracking tools of our own.

2. How We Use Information

The information above is used solely to operate the game: to display the leaderboard, to save and restore your progress on your device, and to enable the sharing and invitation features you choose to use. We do not sell personal data, and we do not use your information for marketing to you outside the game.

3. Third Parties — the Meta Platform

The game is delivered and run by Meta’s Facebook Instant Games platform. Meta processes platform account information under its own Privacy Policy and the Instant Games terms. Your display name, avatar, and leaderboard score are handled through Meta’s platform services. We do not transfer your data to any other third party.

4. Advertising

The current version of the game does not serve advertisements. In the future, the game may display advertisements provided through Meta’s platform advertising services (such as Meta Audience Network). If advertising is enabled, ad delivery will be handled by Meta under its own policies; we will not share additional personal data with advertisers ourselves.

5. Data Storage and Retention

Game progress is stored locally on your device and remains there until you clear it (for example, by clearing your browser or app data) or remove the game. Leaderboard scores are stored by the Meta platform for as long as the leaderboard is active. We do not operate our own servers that store your personal data.

6. Requesting Deletion of Your Data

You may request deletion of the data associated with your use of the game at any time by emailing us at micotom878@gmail.com with the subject line “Data Deletion Request”. Please send the request from the account or include the display name you use on the platform so we can identify the relevant records. We will process verified requests within 30 days. Data held by the Meta platform (such as leaderboard entries) will be deleted or de-identified where the platform tools allow, and we will confirm completion by email. To remove locally stored progress immediately, clear the game’s data in your browser or app settings, or remove the game from your account.

7. Children’s Privacy

The game is offered through the Facebook platform, which requires users to be at least 13 years old (or the minimum age required in their country). The game is not directed at children under 13, and we do not knowingly collect information from children under 13.

8. Changes to This Policy

We may update this policy from time to time, for example if game features change. The updated version will be posted at this same address with a new effective date. Continued use of the game after an update takes effect means you accept the revised policy.

9. Contact Us

If you have questions about this policy or your data, contact us at micotom878@gmail.com.

Effective date: October 21, 2026
