Privacy Policy for NES HD

Introduction

NES HD ("we," "our," or "us") is an Android application for NES and Famicom emulation powered by the Mesen emulation core (the "Service"). This Privacy Policy explains what information the Service accesses, stores, and shares.

Information We Do Not Collect

NES HD is designed to run locally on your device. We do not operate our own account, server, or analytics service, and we do not collect:

• Names, email addresses, or other personal identification information (other than the RetroAchievements sign-in described below, which goes directly to RetroAchievements)
• Contact lists or precise location data
• Advertising identifiers
• Usage analytics, telemetry, or device identifiers for profiling
• Your ROMs, BIOS files, save data, or emulator state

Information Stored or Accessed Locally

To provide emulator functionality, NES HD may store or access the following on your device:

• App preferences, emulator settings, themes, and controller configuration
• Game library metadata, including game names and file locations
• Game files and folders you explicitly choose through Android file-selection flows
• An FDS BIOS file you explicitly select
• Save states, preview images, battery-backed saves, and per-game cheat selections
• High-resolution texture packs and downloaded cover art
• If you sign in to RetroAchievements: your RetroAchievements username and the login token it issues (your password is never stored), your achievement preferences, and cached achievement badge images

Permissions and File Access

NES HD uses Android system file-selection mechanisms so you can open a game or select a ROM folder, FDS BIOS, or texture pack. On Android 12 and earlier, the app may request read access to shared storage so it can find and open game files. On newer Android versions, access is governed by the files and folders you select. NES HD does not upload your selected game or BIOS files.

Network Use and Third-Party Services

Core emulation works locally. NES HD may use internet access to download game cover artwork from repositories hosted on GitHub when your library is displayed. The requested artwork path can identify a game title or region. GitHub may also receive standard connection information such as your IP address and user agent. Review GitHub's Privacy Statement for details.

When you choose Download HD Pack, NES HD downloads a pack catalog and the selected texture pack from GitHub. GitHub receives standard connection information and can see which pack was requested.

The app does not send ROM files, BIOS files, save data, cheat selections, or emulator state to the cover-art or HD pack services.

RetroAchievements (Optional)

RetroAchievements support is off until you sign in. When you sign in, your username and password are sent directly to RetroAchievements.org, which returns a login token that NES HD stores on your device in place of your password. While you are signed in and achievements are enabled, NES HD sends RetroAchievements:

• Your username and login token
• A hash (fingerprint) calculated from the game you start, used to identify the game. The game file itself is never uploaded.
• Achievements you unlock and periodic status updates about the game you are playing

NES HD also downloads achievement lists and badge images from RetroAchievements. This information is handled by RetroAchievements under its own terms and privacy policy, and your activity may be visible on your RetroAchievements profile. You can turn achievements off or sign out at any time in Settings; signing out removes the stored token from the app.

Data Sharing and Sale

We do not sell your personal data, and we do not receive it. NES HD does not operate a remote account or cloud-save backend. Information is sent to third parties only as described above: standard network information to GitHub when it serves cover art or HD packs, and your account and gameplay information to RetroAchievements if you choose to sign in.

Data Retention and Deletion

App data and cached artwork are stored locally on your device. You can remove them by clearing NES HD's storage or uninstalling the app through Android system settings. Files you placed outside the app's private storage may need to be deleted separately using your device's file manager.

Device Backups

Depending on your Android device and backup settings, Android may include eligible NES HD app data in a system backup managed by your device or backup provider. You can manage or disable device backups in Android settings. NES HD does not operate its own backup or cloud-sync service.

Children's Privacy

The Service is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

Security

Because NES HD primarily stores data locally, its security depends on your device and the storage locations you select. Keep your device updated, use its available security features, and only install texture packs and game files from sources you trust.

No Games Included / Legal Notice

NES HD does not include games, ROM files, BIOS files, or commercial artwork. Only use content you are legally permitted to use. NES HD is not affiliated with or endorsed by Nintendo.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page and reflected in the "Last updated" date.
