Wind Over Water StudioPrivacy policy · Updated October 22, 2026
Your climb, your choice.
This policy covers Mad Climb: Wind Over Water (疯狂攀爬), published by Wind Over Water Studio / QIAN FANG, and this website. Contact: fxsmchen@gmail.com. Version 1.0 offers solo play. Version 1.1 adds optional friend multiplayer; the online sections below apply when you choose it.
Solo play and purchases
Language, sound preferences, tutorial completion, local results, the original trial claim time, clock checkpoints and cached purchase access are stored on your device. Apple StoreKit handles trial claims, purchases and restoration. We use verified transaction information locally to determine access and revocations. We do not receive your payment card details or Apple Account password, and do not send StoreKit transaction identifiers to our own server. Restoring a trial preserves its original start time. Uninstalling may erase local progress.
Optional friend multiplayer
Before online services initialize, the app shows an online privacy notice and asks you to agree. You can decline and continue solo. If you agree and create or join a room, Unity Authentication creates an anonymous player identity without an email, password or public profile. Unity Relay connects the two players, and Unity Cloud Code / Cloud Save maintain the private room directory.
These services process the anonymous player ID, IP address and approximate location derived from network information, room and connection identifiers, short-lived security/request records, and the gameplay inputs and state needed to connect and synchronize the match. The other player receives the gameplay state needed for the race. We use this information for authentication, room joining, connection delivery, abuse prevention and gameplay, not advertising or marketing. We do not publish player identities or offer public matchmaking or chat.
Storage and retention
Gameplay state is synchronized between players rather than kept as a cloud save or match-history database. Room directory records are removed on normal exit, or expire after about 90 seconds without renewal and are cleared during the next directory request. Security and replay-prevention references can remain for up to 24 hours and are pruned by a later request; a retired room code can be reserved for 24 hours to prevent accidental reuse. The anonymous authentication identity persists until deleted. Unity Relay retains technical connection data for 30 days. Service providers may retain records required for security, law or their documented retention periods.
Delete your online account
In version 1.1, open Settings → Online privacy → Delete online account and confirm while connected. The app first removes your room-directory references, then deletes your anonymous Unity Authentication account and local authentication credentials. The online consent choice is reset. Your Apple purchase rights and solo progress remain. Joining online again requires agreement and creates a new anonymous identity. Deletion does not immediately erase Unity's retained technical connection logs. For access, correction or deletion requests relating to retained service records, email us; contact us before deleting the identity if you need help identifying it. We may need information to verify the request, but will never ask for passwords or session tokens.
No advertising or usage analytics
The app contains no advertising, does not track you across other companies' apps or websites, and keeps the optional gameplay-usage analytics disabled. We do not enable Unity Analytics or upload tutorial, match-duration or purchase-funnel analytics. Essential multiplayer network processing is separate from optional analytics. The game does not request contacts, photos, camera, microphone or precise-location permissions.
Providers, support and this website
Unity processes multiplayer service data on our behalf; service data may be processed outside your country. See Unity's privacy policy and Relay privacy information. Apple handles store services under its own policies. Device backups follow your device settings.
If you email support, we use your address and the information you choose to send to answer and resolve the request. Do not send passwords, verification codes or payment details. You can request deletion of support messages, subject to required retention. These static webpages have no studio-added analytics trackers, advertising, account login or marketing cookies. The hosting provider may process standard IP, browser and security logs to deliver and protect the site.
Children and changes
The app follows its App Store age rating and is not in the Kids Category. We do not knowingly solicit children's personal information. Contact us with concerns or privacy requests. Policy changes will appear here with an updated date.
