For the Android app · Effective date: October 8, 2026 · Last updated: October 15, 2026
Liar's Dice (the “Game”) is developed and operated by 10K TECH PTE. LTD. (“we”, “us”). This policy explains what information we collect when you play the Game on your Android device, why we collect it, who we share it with, how long we keep it, and how you can access, manage and delete it.
Key points
You can start playing as a guest without giving us your name, phone number or email address.
We do not collect your location, contacts, photos, camera or microphone data.
Ads appear only when you choose “Watch Ad to Claim” for coin relief; these are video ads from Google AdMob. To show them, Google collects information such as your advertising ID (see below). We never sell your personal information.
You can delete your account in the Game at any time. Deletion is completed within 7 days.
1. Information we collect
We collect only the information we need to run the Game:
Category
What it includes
Why we use it
Account information
Player ID (UID), the default nickname we assign or the nickname you choose, language preference, account creation time and last login time
To create and identify your account, and to show your nickname in games
Guest credential
A random credential our server creates when you tap “Play Now”. The credential itself is stored only on your device (in secure, system-protected storage on your device); our server keeps only an irreversible hash of it
To let you keep using the same guest account on this device
Sign-in information (only if you choose to use it)
The user identifier that Google provides for your account. We do not store the name, email address or profile photo of your Google Account
To link your account so you can restore your progress on other devices, and to verify your identity when you delete your account
Game data
Coin balance and coin history, game and bet records, results and statistics, daily task and reward claim records, tutorial progress
To run games and settle coins, to show your records and statistics, and to give in-game rewards
Network and device information
IP address, device type (Android), login records, session tokens
To keep you signed in; to protect your account (for example, an account can be signed in on only one device at a time); to prevent mass sign-ups, reward abuse and cheating; to troubleshoot problems
Advertising information (when you watch an ad)
Collected by the Google AdMob SDK: advertising ID, app set ID, IP address (which may be used to estimate your general location), ad interactions such as views, completed views and taps, and diagnostic information such as app launch time
To show ads and measure them, and to prevent ad fraud (collected and processed by Google)
Information you send us
The contents of emails you send to our support address, such as your email address, a description of the issue and screenshots
To answer your questions and handle your feedback and requests
We do not collect your real name, phone number, contacts, precise or approximate location, photos or videos, camera or microphone data, or health or financial information. We do not use third-party analytics tools. The information collected by the advertising SDK (Google AdMob) is described in the table above.
2. Information stored on your device
Your guest credential and login token are stored in secure, system-protected storage on your device so that you are signed in automatically the next time you open the Game.
Settings such as language and sound volume are stored in the Game’s local storage.
If your account is not linked to Google, you may not be able to recover your guest account and progress after uninstalling the Game, clearing its data or changing devices.
3. How we use information
Providing the Game: creating and restoring accounts, matchmaking, settling coins, and showing records.
In-game rewards: welcome gifts, daily coins, coin relief, daily tasks and similar rewards.
Security and fair play: an account can be signed in on only one device at a time, so signing in on a new device signs out the old one; limiting mass account creation from the same network; detecting and handling cheating and reward abuse.
Support: answering your questions and handling your feedback and deletion requests.
Legal compliance: meeting our obligations under applicable law.
We do not use your game data or account information for advertising or ad profiling, and we do not provide it to Google for those purposes. We do not sell or rent your personal information. The ads you see are selected by Google AdMob; depending on your consent and device settings, they may be personalized or non-personalized.
4. How information is shared
Except where required by law, we share your information only in the following cases:
Google: when you sign in with Google, Google confirms your identity to us. Google’s handling of your information is governed by Google’s Privacy Policy.
Service providers: we use cloud providers to host our servers and store data, and may load static resources such as fonts from content delivery networks (CDNs), which receive network request information such as your IP address. Service providers may process data only on our instructions and must protect it to the same standard as this policy, and we supervise them appropriately.
Other players: your nickname, your bids and dice in a game, game results are visible to players in the same game or to other players.
Legal requirements and safety: when required by law, legal process or a lawful request from a government authority, or when necessary to protect the life, safety, rights or property of our users, the public or us.
Business transfers: if we are involved in a merger, acquisition or transfer of business, we will require the recipient to keep protecting your information under this policy, or ask for your consent.
Some links in the Game (for example, blockchain explorers used to view fairness verification details) open third-party websites in an in-app browser. Those websites are governed by their own privacy policies.
5. How long we keep information
We keep your account information and game data for as long as your account exists.
When you delete your account, within 7 days we delete your account information, sign-in links, coins and coin history, game and bet records, results and statistics, task and reward records, tutorial progress and login records. Your nickname is replaced with a placeholder (“已注销玩家”, meaning “deleted player”).
After deletion we keep:
Game records shared with other players (such as each round’s bids and dice results), so that the other players’ histories stay complete. The player number in these records can no longer be linked to any of your personal information.
A deletion receipt (deletion ID, player ID, request time and completion time) to show that the deletion was completed and to answer related questions. It contains no other personal information.
Support emails are kept for as long as needed to handle follow-up questions after your request has been resolved.
Server logs may contain IP addresses and request times. They are used only for security and troubleshooting and are automatically deleted after a limited period.
Communications between your device and our servers are encrypted in transit.
Your guest credential is stored in secure, system-protected storage on your device on your device, and only a hash of it is stored on our server.
Access to data is restricted to staff who need it for their work.
No security measure is perfect. If a data breach may affect you, we will notify you and the relevant authorities as required by applicable law.
7. Your rights and choices
View and edit: open Account Management from the Game menu to see your player ID, nickname, coins and linked accounts, and to change your nickname.
Link and switch: link Google, or switch to another account, in Account Management.
Delete your account: tap Delete Account in Account Management, or request deletion by email. See Delete Account.
Revoke sign-in access: you can remove the Game’s access on the “Third-party apps & services” page of your Google Account. Revoking access does not delete your game account; to delete it, follow the step above.
Ad choices: in Android Settings you can reset or delete your advertising ID and opt out of ad personalization. In regions where the law requires consent (such as the European Economic Area and the UK), you will be asked for consent before ads are shown. Clearing the app’s data resets your choice, and you will be asked again before the next ad.
Requests about your data: under applicable law, you may ask us to tell you the purposes for which we use your personal data, to disclose, correct, add to or delete it, to stop using or erase it, or to stop providing it to third parties. Depending on where you live, you may also have rights such as data portability or withdrawing consent. Email your request to 10ktech@tech-wings.com. We will respond within the time required by law after verifying your identity. You also have the right to lodge a complaint with your local data protection authority.
8. Minors
The Game is intended only for adults aged 18 or older (or the age of majority where you live, if higher) and is not directed at children. We do not knowingly collect personal information from minors. If you believe a minor has given us personal information, please contact us and we will delete it promptly.
9. Where information is stored
Our servers and service providers may be located outside your country or region. In that case, we take appropriate measures, as required by this policy and applicable law, to protect information transferred abroad.
10. Changes to this policy
We may change this policy and will update the “Last updated” date on this page. If we make significant changes, we will let you know in the Game or by other appropriate means before they take effect, and ask for your consent where the law requires it.
