Crystal Rescue is a free-to-play mobile game. We use data to operate the game, save progress, improve gameplay, process Google Play purchases, show rewarded advertisements, prevent abuse, and understand crashes or performance issues. We do not sell personal information.
This policy applies worldwide. Local privacy rights may vary depending on your country or region.
Information We Collect
| Category | Examples | Purpose |
|---|---|---|
| Game progress and gameplay data | Guest player ID, public player ID, save data, unlocked heroes, purple crystals, gold, stage/frontier progress, reward claims, ad reward counts, and cloud save recovery data. | Operate the game, restore progress, provide rewards, prevent duplicate rewards, and support customer requests. |
| App activity and analytics | Session starts, game entry, level or stage events, shop opens, purchase flow events, rewarded ad events, screen interactions, online time buckets, and gameplay progression events. | Analyze user behavior, identify drop-off points, improve game balance and stability, and measure feature performance. |
| Purchases and transaction records | Google Play product IDs, order IDs, purchase tokens or encrypted token references, purchase status, product price labels, and server verification results. | Deliver purchased purple crystals, verify transactions, prevent fraud, resolve support issues, and keep legally required records. |
| Advertising data and device identifiers | Google Advertising ID where available, ad unit interactions, ad requests, impressions, rewarded ad completions, ad failures, IP-derived approximate region, and consent choices. | Show rewarded ads, measure ad performance, manage frequency and consent, detect invalid traffic, and comply with advertising rules. |
| Device, diagnostics, and performance data | App version, platform, device or installation identifiers, network reachability, crash logs, error codes, latency, and product loading failures. | Maintain security, debug errors, improve loading and performance, and protect the game service. |
| Optional account data | Google Play Games identifiers if you sign in or link an account. | Account linking, cloud save support, and identity recovery. |
Third-Party Services
We use third-party services that may collect or process data under their own policies:
- Google Play for app distribution, in-app purchases, payment processing, order management, refunds, and Play Console reporting.
- Google AdMob and Google Mobile Ads SDK for rewarded advertisements. Users may watch a rewarded ad to receive in-game purple crystals. AdMob may use device identifiers, advertising identifiers, IP-derived location, ad interactions, diagnostics, and consent signals to serve and measure ads.
- Google User Messaging Platform (UMP) for privacy and advertising consent messages where required, including EEA, UK, Switzerland, and other regulated regions supported by Google.
- Firebase / Google Analytics for Firebase for analytics, app events, crashes or diagnostics where enabled, and performance measurement.
- Neon PostgreSQL and Vercel for backend hosting, cloud data storage, API delivery, and operational logs.
Rewarded Ads
Rewarded ads are optional. If you choose to watch an ad, the app may send ad request, display, impression, reward, and failure events so we can grant the reward, enforce daily limits, and understand whether the ad feature works correctly. Watching a rewarded ad currently grants 5 purple crystals, up to the in-game daily limit.
Legal Bases and Consent
Depending on your region, we process data based on contract necessity, legitimate interests, legal obligations, and consent. For personalized ads and certain advertising or analytics uses, we may request consent through Google UMP before requesting ads. You can also use Android and Google settings to reset or delete your Advertising ID or limit ad personalization where supported.
Sharing and Disclosure
We may share data with service providers that help us run the game, including Google, Vercel, Neon, and analytics or advertising providers. We may also disclose information to comply with law, enforce our terms, prevent fraud or abuse, protect users, or respond to valid legal requests. We do not sell user data.
Children
Crystal Rescue is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child provided personal information, contact us through the Google Play listing or the deletion page below.
Retention
We retain gameplay progress while the game account or guest profile remains active. Analytics and operational logs are retained only as long as reasonably needed for analysis, security, debugging, compliance, or legal obligations. Purchase records may be retained longer to comply with tax, accounting, refund, anti-fraud, and platform requirements.
Your Choices and Rights
- You can request deletion of cloud progress, purchase-linked records, and event data through our data deletion page.
- You can reset or delete your Android Advertising ID in your device privacy settings where supported.
- You can manage Google ad settings and consent choices through Google-provided controls where available.
- Depending on your location, you may have rights to access, correct, delete, object to, restrict, or receive a copy of your data.
Security
We use encrypted transport where supported, server-side validation for purchases, access controls, and operational monitoring. No internet service is perfectly secure, but we work to protect the information used to operate the game.
International Transfers
Because Crystal Rescue is available globally, data may be processed in countries or regions outside your own. Service providers may process data in accordance with their own infrastructure, safeguards, and legal obligations.
Changes to This Policy
We may update this policy when we add features, change service providers, or update legal or platform requirements. The latest version will be posted at this URL with an updated date.
