Effective 2 November 2026
This policy explains what information the mobile game Liar (the "Game") collects, why, who it is shared with, and the choices you have. The Game is made by Tziki Applications, Israel ("we", "us"). If you have any question, write to liarapp.support@gmail.com.
You don't sign up. The Game creates an anonymous guest account for you, with a random ID.
Your name and avatar are public: other players see them at the table, on the leaderboard and on your player page.
We keep the results of your online matches to run the leaderboard, your level and your trophies.
We use GameAnalytics to understand how the Game is played, and Google AdMob to show ads. Where the law requires it we ask your consent first, and you can change your answer in Settings › Ads › Privacy.
Notifications are only sent if you allow them.
We never sell your personal information, and we never see your payment details.
Your guest account. When you first start the Game, our backend provider (Supabase) creates an anonymous account: a random player ID and a sign-in token stored on your device. We use it to keep your progress and to let you play online. Your player ID is shown in Settings.
Your profile. The name you choose (or "Guest" with a number), your avatar, the title you wear and your language. Your name, avatar, title, level and public statistics are visible to other players. Names are checked against a list of words that aren't allowed.
Reports. If you report another player’s name, we store your report (who reported whom, the name as you saw it, and when) so we can review it. Only we can read reports; the player is not told who reported them.
Online matches. For each online match: who played (player IDs, including our computer-run "house players"), every move made, the result, and statistics such as bluffs and LIAR! calls. From these we work out your level, experience points, trophies and leaderboard place. Matches against Mitts on your device and the tutorial are not sent to us.
Connection data. To play online your device connects to our game server, which sees your IP address. Our servers keep short technical logs (for example connection times and errors) to keep the service working and to prevent abuse.
Purchases. If you buy something in the Game (such as "Remove ads"), the purchase is handled by Apple's App Store or Google Play. We receive and store a record of the transaction (the product, the store's transaction ID and its status) so we can check it with the store and give you what you bought. We never receive your card or payment details.
Notifications. If you allow notifications, your device's push token (from Apple's Push Notification service or Google's Firebase Cloud Messaging) is stored with your account so we can send you notifications about the Game. You can turn them off at any time in the Game (Settings > Notifications) or in your phone’s settings.
Game analytics. We use GameAnalytics to see how the Game is played: for example which screens are opened, how matches go, where the tutorial loses people, and crashes. GameAnalytics receives these events together with technical information such as the device model, operating system, app version, an identifier GameAnalytics creates for your installation, and an approximate country derived from your IP address. We do not send your name or your player ID to GameAnalytics. See the GameAnalytics privacy notice.
Advertising. The Game shows ads through Google AdMob: ads you choose to watch (for example to borrow a card back) and, now and then, an ad between matches. Ads never appear during a match. To show and measure ads, Google may collect your device's advertising identifier (the IDFA on iOS, if you allow tracking; the Android advertising ID), your IP address, device information and how you interact with the ads. Ads in the Game are limited to content rated for teens.
In the European Economic Area, the UK and Switzerland, Google's consent form asks for your choices before any personalized ads are shown. You can change them any time in Settings › Ads › Privacy.
On iPhone, Apple asks whether the Game may track you. If you say no, you'll still see ads, but they won't be personalized using your advertising identifier.
On Android you can reset or delete your advertising ID in your phone's settings.
See how Google uses information from apps that use its services.
On your device only. Your settings (sound, music, language, difficulty and similar) are saved on your device and are not sent to us.

Processing and verifying purchases
Other players see your public profile (name, avatar, title, level and statistics). We may also disclose information if the law requires it. We do not sell personal information.
These providers may process information in countries other than yours, including the United States and the European Union, under their own safeguards.
We process your information to provide the Game you asked for (your account, progress and online play); for our legitimate interests in keeping the Game working, secure and fair and understanding how it's played (analytics and logs); and with your consent where the law requires it (personalized ads, tracking on iOS, notifications). You can withdraw consent at any time as described above; this doesn't affect processing that happened before.
We keep your account, profile and match history for as long as your account exists. Server logs are kept for a short time. When you delete your account (in the Game, Settings > Delete my data) or ask us to, we delete or anonymize your personal information, except where we must keep a record by law (for example of a purchase). Information held by GameAnalytics and Google is kept under their own policies.
You can ask us to access, correct or delete your personal information, to receive a copy of it, or to object to or restrict how we use it. You can delete your account yourself in the Game: Settings > Delete my data. For anything else, email liarapp.support@gmail.com and include the Player ID shown in Settings, so we can find your account (we have no other way to know which guest account is yours). You can also complain to your local data protection authority; in Israel, the Privacy Protection Authority.
The Game is not meant for children under 13, and we don't knowingly collect personal information from them. If you believe a child under 13 has used the Game, contact us and we will delete the account.
We may update this policy as the Game changes. We will change the date at the top, and for significant changes we will let you know in the Game.
