Terms of Use

1. Scope and acceptance

These Terms of Use apply to Tintslide / 方即是空 (the “game”) and its daily leaderboard, provided by Lantao Studio. Read these terms and the Privacy Policy before playing. If you do not accept these terms, stop using the game. The Privacy Policy explains data handling; reading or accepting these terms does not constitute consent to personalized advertising or cross-app tracking. If you are below the age at which you can enter an agreement where you live, a parent or guardian should review these terms and approve and supervise your use.

2. The game and local progress

The game is free and offers Campaign, Puzzle and Daily Endless, with no account registration or in-app purchases. Campaign and Puzzle can be played offline after installation on Android or iOS, or after resources have loaded and been cached in the web / PWA version. Downloads, updates and leaderboards need a connection. Progress, preferences, records and device identity are stored in your current browser or device; clearing data, uninstalling, device failure or switching devices may cause loss. The game provides no account login, cloud-save or identity-recovery service. Restoration through an Android or iOS system backup depends on your system settings. Local saves are not permanent backups.

3. Daily leaderboard and nicknames

Daily Endless automatically submits results, action records and verification data after a run ends or is settled at a day change. Offline submissions retry when connected; acceptance depends on the challenge day, submission deadline and rules version. The leaderboard publicly shows your nickname (or “Anonymous”), score, move count and rank. Days follow UTC, with one free run per device identity each day. The Google Play and App Store (iOS) versions offer replays through the rewarded ads described below; the leaderboard keeps your highest submitted score for the day. See the game for tie-breaking, deadlines and other rules. Rankings may change with late submissions, validation or corrections. Rankings do not award prizes, cash or rights with real-world monetary value.

4. Fair use and user content

Do not forge scores, tamper with submissions, exploit bugs or multiple identities to evade daily limits, disrupt the service or send automated abusive requests. Nicknames must not impersonate others, infringe rights or contain unlawful, hateful or harassing material or another person’s private information. You retain rights in original content such as nicknames and authorize us to use it only to display, maintain and administer the leaderboard. We may take proportionate action against violations or invalid records, including correcting or removing results, hiding nicknames or restricting online features. Contact the operator to dispute an action.

5. Advertising and optional rewards

The web / PWA and TapTap versions have no advertising. The Google Play and App Store (iOS) versions have three Google AdMob ad placements. The Classic line of Campaign has no advertising at any point.

• Daily replay: after a Daily Endless run ends, you may choose to watch a rewarded video to replay that day’s challenge.
• Puzzle solution: before you view the solution to a level on the Puzzle line of Campaign for the first time, you may choose to watch a rewarded video. Once the reward arrives, that level’s solution is unlocked permanently on this device and needs no further ad.
• Random interstitial: on the Random line of Campaign, an interstitial ad is shown before the next level every five newly cleared levels. It is not a rewarded ad: it can be closed and need not be watched in full, and closing, skipping or a failure to play still lets you continue to the next level.

Reward conditions and use limits for rewarded ads are shown before viewing, and none start until you choose to watch. Ads may be unavailable because of connectivity, region or inventory; leaving a rewarded ad early or missing a valid completion confirmation may prevent a reward. Refusing advertising consent may result in limited ads or no ads. If an ad is unavailable, you cannot earn a replay or a solution unlock by watching one, but your free daily run, Campaign and Puzzle remain fully playable. “Permanently” above means for as long as this device’s local save exists; unlocks do not travel across devices or follow an account, and do not survive clearing data or uninstalling. Rewards cannot be exchanged for cash or transferred, and do not require clicking an ad or buying anything. Third-party ads and links are not endorsements; third-party transactions have their own terms, without reducing our legal responsibilities. See the Privacy Policy for advertising data handling and choices.

6. Intellectual property

Rights protect the game’s code, artwork, audio, text, branding and levels; third-party materials retain their own licenses. Subject to these terms, you may use the officially provided game for personal, noncommercial entertainment. Unless permitted by law or separately authorized by the rights holder, you may not copy, sell or distribute the game or its assets. These terms grant no source-code or trademark license and do not limit rights granted by third-party licenses.

7. Service changes and liability

We may update gameplay, content and services, or suspend online features for maintenance, security or operational reasons. Material changes will be reasonably announced in the game or on its distribution page. We will use reasonable care but cannot guarantee uninterrupted or error-free service or permanent progress and rankings. To the extent permitted by applicable law, we are not responsible for losses that could not reasonably be foreseen or were beyond our reasonable control. Nothing excludes or limits liability that cannot lawfully be excluded, including liability for fraud, intent or gross negligence, or your statutory consumer rights.

8. Ending use, changes and disputes

You can stop using the game at any time; see the Privacy Policy for data handling and deletion. Revised terms will show their update date. Material changes affecting your rights or obligations will receive reasonable notice, with separate agreement where legally required. Contact the operator first to try to resolve disputes. Applicable law and competent courts are determined by law; these terms do not impose arbitration or remove mandatory consumer protections where you live. The Chinese and English versions aim to convey the same meaning; applicable law governs interpretation differences.
