Privacy Policy
JJJI STUDIO provides this policy for the Android game “Cross Together” (Korean title: 다 같이 건너요 - 강 건너기 퍼즐; package: com.jjjistudio.crosstogether) and its official game webpages. Effective and last updated: November 13, 2026.
1. Contact
The operator and privacy contact is JJJI STUDIO, [email protected]. Contact us for privacy questions or access, correction and deletion requests. We may ask for information reasonably necessary to verify and respond to your request.
2. Information stored on your device
The game has no registration or developer-operated account server. Progress, stars, last stage, hint balances, worlds unlocked by rewards in earlier versions, boat customization, completion counts used to space interstitial ads, daily reward status, tutorial progress and language, audio and vibration preferences are stored on your device. Recent play records used for troubleshooting are also stored locally. They are not automatically sent to a developer server. If you copy test logs or attach them to a support message, you choose how to share them.
To prevent invalid ad traffic and limit ad frequency, the game stores ad click and impression timestamps, rewarded-ad display timestamps, restriction expiry times, restriction counts and reference times, and the latest observed time used to guard against the device clock moving backwards. These protection records stay on the device and are not automatically sent to a developer server. Information processed separately by the Google advertising SDK is described in the advertising sections below.
To prevent lost or duplicate rewards, the game stores the pending reward type and relevant stage identifier. It also keeps a list of solutions unlocked through ads so they can be viewed again. If the app closes after receiving the reward signal but before granting the reward, this pending state is used for recovery at the next launch. Once the reward is applied, the pending state is cleared from the current save. A backup of the previous valid save is also kept on the device to recover from storage errors.
3. Advertising and Google services
The game uses Google AdMob rewarded and interstitial ads and Google User Messaging Platform (UMP). Rewarded ads for hints and solutions are optional. From version 0.1.2, world-unlock ads are no longer used. Interstitial ads may appear when moving to the next stage after a completion, subject to completion-count and time intervals; the first world and tutorial are excluded. They do not appear at app launch or exit, or during failures or retries. At launch, the app checks consent status. Where consent is obtained or not required, it may initialize the advertising SDK and preload ads. Advertising data may therefore be processed before you tap an ad button. Google may collect or share IP addresses and approximate location derived from them, device/app identifiers such as advertising ID and app set ID, ad/app interactions, device/app information and diagnostics for advertising, measurement, fraud prevention and service operation. Processing depends on your region, device settings and consent choices. The game does not request contacts, photos, microphone, camera or precise GPS location. The developer does not operate a separate analytics SDK or account-based tracking server.
4. Consent and choices
Google consent screens are shown where applicable. Where privacy options are required, the Privacy choices button in game settings lets you review or change advertising consent. Android privacy and advertising settings provide additional controls, including controls over the advertising ID. Core puzzles can be played without choosing rewarded ads; ads and ad rewards require connectivity. Refusing personalized advertising does not necessarily stop processing needed for ad delivery or security.
5. Support and website
If you email us, we use your email address, message and voluntarily provided attachments to respond and resolve the issue. Please avoid unnecessary personal information. The official website is hosted through Cloudflare, which may process IP addresses, browser details, request times and similar access information to deliver and secure pages and troubleshoot service issues. We have not added separate visitor analytics or advertising to these game information and policy pages.
6. Retention, deletion and international processing
Ad protection evaluates events from the preceding seven days and keeps up to 200 recent entries for each of clicks, impressions and rewarded-ad displays. Older events are pruned when the relevant records are added or updated; if the app is unused or records are not updated, they may remain in files and backups longer. Protection state, including restriction counts, reference and expiry times and the latest observed time, is stored separately from events and may remain until app data is deleted. At the next click evaluation, the restriction count decreases by one for each 30-day period without a new restriction; this does not delete all protection information.
The in-game clear-records option resets progress; it does not erase all app data. Ad protection records, previously unlocked solutions, recent gameplay records and some preferences may remain. Use the operating-system deletion methods below to remove the complete local save and its in-app backups. An earlier pending-reward state may also remain in a backup until that backup is replaced or deleted.
You can delete local game data through Android app storage settings or by uninstalling the app. This may erase progress and rewards, which the developer cannot restore. We retain support information as needed to answer and resolve the issue, then delete it, subject to legally required retention. Google and Cloudflare determine retention and deletion for information they process under their respective policies and settings. Their global infrastructure may process information outside your country. Their policies below explain safeguards and rights procedures.
7. Children
The game is intended for users aged 13 and older. The developer does not knowingly collect personal information from children under 13; higher protected ages may apply in your region. If you believe a child has provided personal information through support or otherwise, contact us so we can investigate and delete it as appropriate.
8. Protection, rights and changes
We limit access to support information to what is needed and avoid keeping unnecessary information. Depending on applicable law, you may request access, correction, deletion, restriction or withdrawal of consent. For device-only data and Google data, use the device or service controls described above. Material changes will be posted on this page with an updated effective date.
