Privacy Policy

Chime Blast on TikTok · Effective October 14, 2026

This policy covers the TikTok mini game operated by 北京库哈科技工作室（个人独资） / BEIJING KUHA TECHNOLOGY STUDIO (SOLE PROPRIETORSHIP), China. Contact: i.hou@163.com.

Information used to run the game

When you launch the game in TikTok, TikTok provides a temporary login code. Our server exchanges it with TikTok for an app-specific account identifier (OpenID). We derive a pseudonymous player identifier to keep different accounts’ local saves separate. We retain the OpenID and last login date on our server for up to 90 days after your last login. We do not request your TikTok profile name, avatar, contacts, messages or videos. Access and refresh tokens obtained during this exchange are not retained.

Your level progress, coins, items, audio settings and reward receipts are saved in the TikTok app’s local storage on your device. They are not uploaded to our server or synchronized across devices. Clearing app data, changing device or removing the game may erase this progress.

Optional rewards and advertisements

Where available, you may choose to watch a TikTok rewarded advertisement or use a home-screen shortcut or profile revisit mission. TikTok handles the ad, shortcut and mission interface and tells the game whether you are eligible for a reward. The game records completed rewards locally to prevent duplicate delivery. We do not receive payment-card details or offer in-app purchases in this edition.

Service providers and data sharing

TikTok processes platform login, advertisements and mission interactions under its own privacy policies. Cloudflare hosts our login service and these pages. Network requests necessarily expose technical information such as IP addresses to these providers; we use IP-based rate limiting to protect the login endpoint. Our application code does not log login codes, access tokens or player identifiers. We do not sell your personal information or use a separate advertising or analytics SDK.

Purposes, retention and international processing

We process login identifiers to provide the requested game service, separate local account saves and prevent abuse. We use service providers that may process data outside your country. Server identity records expire 90 days after your most recent login. Local save data remains until removed from the device. Support messages are kept only as needed to resolve your request and meet applicable obligations.

Your choices and rights

Advertisements and revisit missions are optional. You can stop using the game, manage app permissions through TikTok, or remove local app data. For access, correction, deletion or other applicable data rights, contact i.hou@163.com and identify this game. We may need to verify your request. If applicable, you may also complain to your local data protection authority. Please do not send identity documents unless we specifically need and request them.

Children

The game is available only to users eligible to use TikTok and the mini-game service in their region. We do not knowingly seek personal information from children below the applicable minimum age. A parent or guardian may contact us about a child’s data.

Changes

We will update the effective date when this policy changes and provide any additional notice or choice required by applicable law.
