CoinMadang provides market and onchain information and the KaiaPulse calculator without an account. The production Android app includes rewarded ads for viewing calculator results. Development and test builds use official test ads. Website advertising and cookies are described separately. Mobile notice updated: 2026-09-08.
Information stored on your device
The mobile app stores watchlists, appearance and app settings, exchange and calculator catalogs, and recent valid market and onchain data on the device. Calculator inputs and results are calculated locally; they are not sent to the ad SDK, data server, URLs, logs or analytics, or saved permanently. The website may store language, display settings and consent choices in browser storage or cookies to operate the service.
Network processing
The app and website request data from CoinMadang public data services and external market and onchain providers. The app also uses restricted public asset-image URLs. Infrastructure providers may process IP addresses and ordinary request metadata for delivery, operation and security. If you send a support email, its contents, reply address and app/device details you review are sent to support staff and the mail service. The app does not send email automatically.
Mobile rewarded ads and consent
The production Android app uses one rewarded ad format through Google Mobile Ads SDK to unlock calculator results. The SDK may process IP addresses (to estimate general location), ad interactions, diagnostics and identifiers such as advertising ID and app set ID; data is encrypted in transit. The SDK initializes and requests ads only when UMP permits ad requests. Where applicable, change your choice through advertising privacy options in Settings. A reward opens results for the current inputs for 30 minutes; changed inputs lock them again. Closing or cancelling without a reward, no available ad, or network/SDK failure preserves inputs and keeps results locked. Firebase Analytics, Crashlytics, banner, interstitial and app-open ads are not included. Ads may be unavailable during review. Google Mobile Ads SDK
Web advertising and cookies
When web advertising is enabled, Google and its advertising partners may use cookies, web beacons, IP addresses, device and browser information, and advertising interactions to deliver ads, manage frequency, prevent abuse, and measure performance. Third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this website or other websites. Where consent is required, a Google-certified consent management platform (CMP) lets you accept, reject, or manage these choices. See How Google uses information from partner sites and manage Google advertising choices in My Ad Center.
Accounts, sale of personal information, and service scope
No login or account is required, and CoinMadang does not sell personal information. The current mobile app has no community, points, profile or address-entry feature. Website ads are served only after AdSense approval and the required operating settings are enabled. CoinMadang provides no trading, orders, wallet creation, connection or custody, deposits, withdrawals, investment advice or guaranteed returns. Revealing calculator results is not a cash, coin or other external reward.
Deletion, choices, and contact
In-app “Reset display mode” restores only the default dark theme, and “Clear watchlist” removes only watchlist entries. To remove all local app data, use Android Settings → Apps → CoinMadang → Storage → Clear data, or uninstall the app. OS backup and restore, advertising identifiers and consent information are also subject to platform and SDK controls. On the web, clear site data and cookies in your browser; change web ad choices in its privacy/cookie settings or My Ad Center. There is no current server account. Contact support@coinmadang.app about access to or deletion of older community materials or support emails. This does not mean those records have already been deleted; applicable records and retention reasons will be checked and explained.
