CoreDM is a free, ad-supported download manager for Android. We collect the minimum data needed to serve ads, verify rewarded ad completions, detect tampering, and fix crashes. We never sell your data. We never collect your files, browsing history, identity, or location.
CoreDM is developed and operated as an independent Android application. For privacy inquiries, contact coredmdev@gmail.com.
This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the CoreDM mobile application (the “App”). By using the App, you consent to the data practices described in this policy.

| Advertising ID Resettable, non-permanent identifier provided by Google Play Services |
Serve ads (banner, interstitial, rewarded video) | Google AdMob (advertising network) |

Verify rewarded ad completions via server-side verification (SSV); detect persistent ad-blocking | Cloudflare Workers (serverless function); Firebase Firestore (cloud database) |

Google AdMob (advertising) and Firebase Crashlytics (crash reporting) are Google services that may collect additional data according to their own privacy policies. This may include:
These data elements are collected and processed by Google, not by us directly. Refer to Google’s Privacy Policy for full details.
| Purpose | Data Used | Legal Basis (GDPR) |
| Display advertisements to fund the free App | Advertising ID, IP (via AdMob) | Legitimate Interest (Article 6(1)(f)) |
| Verify rewarded ad completions for ad-free credit | Android ID (SSV callback) | Legitimate Interest (Article 6(1)(f)) |
| Detect ad-blockers to protect revenue (the App is ad-only) | Ad failure count (error codes) | Legitimate Interest (Article 6(1)(f)) |
| Diagnose and fix application crashes | Crash stack traces (opt-in) | Consent (Article 6(1)(a)) |
| Detect tampered/cracked app installs | Hashed device fingerprint | Legitimate Interest (Article 6(1)(f)) |
Under GDPR Article 6(1)(f), “Legitimate Interest” means the processing is necessary for our legitimate business interests (operating a free ad-funded service, preventing fraud) and does not override your fundamental rights and freedoms.
We share data with the following service providers who process data on our behalf. Each provider is contractually obligated to protect your data and use it only for the purposes we specify:
| Provider | Service | Location | Privacy Policy |
| Google LLC | AdMob (advertising) | United States | Link |

| Google LLC | Firebase Firestore | United States | Link |
| PostHog, Inc. | Security telemetry | United States / EU | Link |
| Cloudflare, Inc. | Serverless functions (SSV, integrity) | Global edge network | Link |
CoreDM does not sell, rent, trade, or lease personal information to any third party for monetary or other valuable consideration. We do not share data with data brokers, advertisers beyond AdMob’s standard ad serving, or any other commercial entities.
OFF by default. Toggle in Settings → Advanced → Crash Reports. When off, no crash data is sent to Firebase Crashlytics.
Watch a rewarded ad to earn 3 hours of ad-free time. While credit is active, all ad loading is suppressed. No ad-related data is collected during this period.
Android provides a system-level control to reset your advertising ID:
Settings → Google → Ads → Reset advertising ID
This replaces your identifier with a new, random one, unlinking future ad activity from past activity.
We may update this Privacy Policy from time to time. We will notify you of material changes by:
You are advised to review this Privacy Policy periodically. Continued use of the App after changes are posted constitutes acceptance of the updated policy.
