Idle Rune Foundry — Privacy Policy

Last updated: April 16, 2026

CrashBytes ("we", "our", or "us") operates the Idle Rune Foundry mobile application on both iOS (Apple App Store) and Android (Google Play). This privacy policy explains how we collect, use, and protect your information across both platforms.

Information We Collect

Analytics (Firebase Analytics)

We use Google Firebase Analytics to understand how players interact with the game. This includes:

  • Gameplay events (runes forged, upgrades purchased, prestige resets)
  • Feature usage (store visits, forge skin changes)
  • App performance metrics
  • Device type and operating system version

Analytics data is collected in aggregate and does not personally identify you. You can opt out of analytics by limiting ad tracking in your device settings (see "Your Rights" below).

Crash Reporting (Firebase Crashlytics)

We use Firebase Crashlytics to detect and fix app crashes. When a crash occurs, Crashlytics collects:

  • Device state at the time of the crash
  • Device model and OS version
  • Stack trace information

Crash reports do not contain personally identifiable information.

Advertising (Google AdMob)

On Android, rewarded video ads are served by Google AdMob via the Google Mobile Ads SDK. Watching a rewarded ad is always optional and grants in-game rewards.

  • AdMob and its ad network partners may use advertising identifiers (Google Advertising ID / GAID on Android, IDFA on iOS) to serve and measure ads.
  • AdMob may also collect general device and network information (device type, OS version, coarse location derived from IP, and ad interaction events) to deliver relevant ads and prevent fraud.
  • Purchasing the Remove Ads in-app product disables serving of rewarded ads in the app.
  • You can reset or limit ad tracking at any time: on Android, go to Settings > Google > Ads and enable "Delete advertising ID" or "Opt out of Ads Personalization"; on iOS, go to Settings > Privacy & Security > Tracking and disable "Allow Apps to Request to Track", or use Settings > Privacy & Security > Apple Advertising.
  • Ad serving by Google is governed by Google's Advertising Privacy & Terms.

In-App Purchases

Purchases (gem packs and the Remove Ads entitlement, priced from $0.99 to $19.99) are processed entirely by the platform you installed the app from — Apple through the App Store on iOS, or Google through Google Play Billing on Android. We do not collect, process, or store any payment information, credit card numbers, or billing details. Purchase receipts are validated by the respective platform.

Local Notifications

The app can schedule local reminder notifications (e.g. "your forge is ready") that run entirely on your device using iOS UserNotifications or Android WorkManager. No notification content is sent to or through our servers. On Android 13 and above, the app requests the POST_NOTIFICATIONS permission; you can revoke it at any time in system settings.

Ratings Prompt

The app may occasionally display the native rating prompt (SKStoreReviewController on iOS, Play In-App Review on Android). These prompts are handled entirely by Apple and Google; we do not receive your rating or review text.

Information We Do NOT Collect

  • Personal information (name, email, phone number)
  • Precise location data
  • Contacts or address book
  • Photos, camera, or microphone access
  • Health or fitness data
  • Browsing history
  • Account or login information (no accounts required, no cloud sync)

Android Permissions

The Android build declares only the following permissions:

  • INTERNET and ACCESS_NETWORK_STATE — required to load rewarded ads, send analytics/crash reports, and validate purchases.
  • com.android.vending.BILLING — required for Google Play in-app purchases.
  • POST_NOTIFICATIONS — required on Android 13+ to show local reminder notifications.
  • VIBRATE — used for haptic feedback during gameplay.

Data Storage and Security

Game progress is stored locally on your device only. We do not store any player data on our servers and the app does not offer cloud save or account sync. Analytics and crash data are stored on Google Firebase servers and are subject to Google's Privacy Policy. Ad-related data handled by AdMob is subject to Google's Advertising Privacy & Terms.

Children's Privacy

Idle Rune Foundry is rated 4+ (App Store) / Everyone (Google Play) and is suitable for all ages. We do not knowingly collect personal information from children under 13. The game does not require any account or login.

Third-Party Services

  • Apple — App Store (iOS purchases)
  • Google Play — Google Play Billing (Android purchases)
  • Google Firebase — Analytics and Crashlytics
  • Google AdMob — Rewarded video ads on Android (Google Mobile Ads SDK)

Your Rights

You can:

  • Play the game without any data leaving your device beyond analytics and ads
  • Delete the app to remove all local data
  • Opt out of ad personalization / analytics on iOS via Settings > Privacy & Security > Tracking and Settings > Privacy & Security > Apple Advertising
  • Opt out of ad personalization on Android via Settings > Google > Ads ("Delete advertising ID" or "Opt out of Ads Personalization")
  • Disable the POST_NOTIFICATIONS permission for the app on Android to stop local reminders
  • Purchase "Remove Ads" to disable rewarded ad serving
  • Request deletion of analytics and crash data — see Delete Your Data for the full process

We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date.
