Privacy Policy

This Privacy Policy explains how VNGGames Co., Ltd ("we", "us", or "our") handles information in connection with Sand Sort (the "Game") as a TikTok Mini Game, played inside the TikTok app (TikTok Mini Games App ID 7683382138859522056).

Sand Sort is a single-player colour and pixel-picture puzzle game. It is free to play, has no in-app purchases, and has no user-generated content that is shared with other people.

By opening or playing the Game inside TikTok, you agree to the practices described in this Privacy Policy. If you do not agree with this policy, please do not use the Game. Please read this policy together with our Terms of Service.

1. Who We Are

The TikTok Mini Games version of the Game is published by VNGGames Co., Ltd.

Your use of the Game is also subject to the terms and privacy policy of TikTok, the platform on which the Game runs. This policy covers only the Game itself. It does not cover TikTok, or any other third-party websites or services that may be linked from advertisements, which are governed by their own privacy policies.

2. Information We Collect

We designed the Game to collect as little information as possible. We do not ask you to create an account with us, and we do not knowingly collect your name, email address, phone number, precise GPS location, contacts, photos, or financial information. The Game contains no in-app purchases.

You do not enter any password or credentials into the Game. TikTok signs you in silently, and the only identifier we receive is the pseudonymous OpenID described below.

2.1 Your TikTok OpenID (open_id)

When you open the Game inside TikTok, TikTok performs a silent sign-in: the Game receives a short-lived authorization code from TikTok and exchanges it, through our server, for an OpenID (open_id) — a pseudonymous identifier that TikTok issues for you specifically for this Game. We use it only to identify your player session and to attach your game progress and advertising/mission events to a stable identifier.

We do not receive, request, or store any other information from your TikTok account. We do not receive your username, display name, profile picture, email address, phone number, date of birth, follower list, or any video or message content. The open_id is specific to this Game and cannot be used by us to identify you on TikTok or on any other service.

2.2 Information stored locally on your device

The Game stores the following in the local storage that TikTok assigns to it on your device. It is not, by itself, transmitted to us as personal data:

• Game progress and settings — such as your current level, unlocked content, virtual items, and your in-game preferences.
• Technical values needed to run the Game — such as cached configuration and the identifier described in Section 2.1.

There is no cloud save. If you clear TikTok's data, remove the Game, or switch device or TikTok account, this locally stored progress may be permanently lost.

2.3 Remote configuration we read (no personal data)

The Game reads configuration values — such as level configuration, advertising unit identifiers, and gameplay settings — from a Google Firebase Realtime Database and from our content delivery network (CDN), over ordinary HTTPS requests. These requests are read-only: the Game only downloads configuration and game content. It does not write your progress, your open_id, or any other personal data to that database.

As with any HTTPS request, the hosting infrastructure may process technical connection information such as your IP address and the time of the request in order to deliver the response and to protect the service.

2.4 Information collected by TikTok

Separately from the above, TikTok itself collects information when you use a mini game inside the TikTok app — including information used to select and measure the advertisements described in Section 4, and information relating to the optional platform missions described in Section 5. That collection is carried out by TikTok as described in TikTok's own privacy policy, and is outside our control.

3. How We Use Information

We use the information described above for the following purposes:

• To operate, provide, and maintain the Game and to save your progress.
• To identify your player session using the pseudonymous TikTok open_id.
• To show rewarded video advertisements and to grant the corresponding in-game rewards.
• To determine whether an optional platform mission is eligible for an in-game reward.
• To load remote configuration and game content that keeps the Game working correctly.
• To detect and prevent cheating, fraudulent advertising activity, and abuse of the Game.

We do not build advertising profiles about you, and we do not sell your personal data.

4. Advertising

The Game is free to play and is supported by advertising. It shows rewarded video advertisements, which you always choose to watch in exchange for an in-game reward — they are never forced on you.

These advertisements are served by TikTok In-App Ads, provided by the TikTok platform. Ad selection, delivery, and measurement are handled by TikTok using the information described in TikTok's privacy policy. The Game does not pass your open_id to advertisers, and it does not read or transmit any device advertising identifier.

Your choices: ad personalisation for TikTok In-App Ads is controlled through your TikTok account and app settings (for example TikTok's ads/personalisation settings), not by us. Limiting ad personalisation does not remove advertisements from the Game, but it limits how your information is used to select them. You can also simply choose not to watch rewarded advertisements.

5. Optional Platform Missions

The Game offers two optional missions provided by the TikTok platform: adding a shortcut to the Game to your device's home screen, and opening the Game from the TikTok profile sidebar and returning to it. Completing a mission may make you eligible for an in-game reward, which is a virtual item with no monetary value (see our Terms of Service).

For these missions, we receive from TikTok only a signal indicating whether a mission is eligible for a reward. We do not receive information about your device's home screen, your TikTok profile, or your activity elsewhere in TikTok. Participation is entirely optional.

6. Children's Privacy

The Game is not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction, or the higher minimum age required by TikTok). We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us at the email below so we can take appropriate action.

7. Data Retention

Data stored locally on your device (game progress, settings, and cached values) remains there until you clear TikTok's data for the Game, remove the Game, or uninstall TikTok.

Where we hold the pseudonymous open_id and related gameplay events on our side, we keep them only for as long as needed to operate the Game, to prevent fraud and abuse, and to meet our legal obligations, after which they are deleted or aggregated. Information collected by TikTok, and by Google in respect of the Firebase Realtime Database we read configuration from, is retained by those companies for the periods described in their own policies.

8. Your Rights & Choices

Depending on where you live, you may have rights to access, correct, or delete personal data relating to you. Because the Game has no account with us and the only identifier we hold is pseudonymous, we may not be able to identify a specific individual from it. You can still exercise the following controls:

• Delete local data: clearing the TikTok app's data for the Game, or removing the Game from TikTok, removes the game progress stored on your device.
• Control ad personalisation: use your TikTok account and app settings, as described in Section 4.
• Skip optional features: you can play the Game without watching rewarded advertisements and without starting any platform mission.
• Make a request: to ask questions about your data or to submit an access or deletion request, contact us at fgs.studio.store@gmail.com. Please tell us that you play the Game on TikTok so that we can locate the pseudonymous open_id associated with your request. Requests about data held by TikTok itself must be made to TikTok directly.

9. Security

We take reasonable technical and organizational measures to protect information handled by the Game, including transmitting data over HTTPS. However, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee absolute security.

10. International Users & Data Transfers

The Game relies on the TikTok platform, on our servers, and on Google Firebase and CDN infrastructure, all of which operate globally. As a result, information may be processed and stored on servers located in countries other than your own, including countries whose data-protection laws may differ from those in your jurisdiction. Where required, such transfers are handled under the safeguards described in the relevant provider's privacy policy and in the applicable data-transfer mechanisms.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Effective date" shown at the top of this page and publish the updated policy at this URL. Significant changes may be communicated through the Game or through its TikTok Mini Games listing. Your continued use of the Game after an update takes effect constitutes acceptance of the revised policy.
