Privacy Policy — Nostalgience

Information Collection and Use

DC Enhancements built Nostalgience as a mobile application. This service is provided by DC Enhancements and is intended for use as is.

The app may process technical or account-related data required to deliver its features, keep the service secure, and resolve support issues. We limit collection to the minimum necessary for the feature you actively use.

• Library/file metadata, persistent document links, saves, screenshots, settings, controller layouts, pairing state, transfer history and diagnostics are stored locally for the features you choose.
• DCE support/core/update downloads can send IP address, user agent, requested resource, timestamps, error status and download metadata to DC Enhancements infrastructure.
• Optional cover-art lookup can send title/platform data in a request path to GitHub/Libretro thumbnail hosting.
• Nostasync sends selected session content and device/network data directly to the LAN device you deliberately pair.
• Google Play Integrity may process installation, app-integrity and licensing information to prevent tampering and unauthorized copies of this one-time paid Play app.

Permissions

The app may request the following Android permissions to provide its features:

• android.permission.INTERNET — connect to online services that provide core app functionality
• android.permission.ACCESS_NETWORK_STATE — detect whether a network connection is available before contacting remote services
• android.permission.CHANGE_WIFI_MULTICAST_STATE — support a user-facing feature that depends on this Android permission
• android.permission.BLUETOOTH — support a user-facing feature that depends on this Android permission
• android.permission.BLUETOOTH_ADMIN — support a user-facing feature that depends on this Android permission
• android.permission.BLUETOOTH_CONNECT — connect to nearby Bluetooth accessories selected by the user
• android.permission.BLUETOOTH_SCAN — support a user-facing feature that depends on this Android permission
• android.permission.VIBRATE — support a user-facing feature that depends on this Android permission

Third-Party Services

The app does not intentionally rely on third-party analytics, ads, or payment SDKs beyond the services required to distribute the app through Google Play.

Ads and In-App Purchases

The app does not include advertising and does not process in-app purchases unless this policy is updated to state otherwise.

Data Retention

Library entries, saves, screenshots, settings, persistent document links, paired-device state and logs remain locally until you delete them or remove Android app data. Cache files are removed after 7 days and temporary Nostasync session files after 18 hours. App data is excluded from Android cloud backup and device-to-device transfer. Server request logs are retained only as needed for delivery, security, abuse prevention and troubleshooting.

Children's Privacy

Nostalgience is a Game Boy, Game Boy Color and Game Boy Advance library/player for games users legally own; it is not directed to children under 13. Parents should note that library data and Nostasync transfers remain local or are deliberately shared with a paired device.

Local Library, Files and Storage Access

Nostalgience stores local library entries, selected file/folder document links, file names and paths, checksums, file size, platform/core selection, artwork, favorites, play time and session times, saves, screenshots, controller layouts, cheats, settings, paired devices and transfer history. File or folder access is granted only when you select it through Android's picker and can persist until you remove the link in the app or remove app data. The app does not automatically back up or transfer these app data through Android cloud backup.

DCE Downloads, GitHub Artwork and Technical Logs

When you explicitly request signed DCE core packs, support data, updates or app resources, Nostalgience contacts DC Enhancements infrastructure. Normal server logs can include IP address, user agent, requested resource, timestamps, error status and download metadata. Optional cover-art lookup can request a title and platform path from GitHub/Libretro thumbnail hosting; the request can expose normal network metadata and title/platform data in the URL path. Runtime logs and crash reports are created locally and can contain paths, file names and error details; they are not automatically uploaded, but are shared with a recipient only when you explicitly use a share action.

Nostasync and Local Network Transfers

Nostasync lets you deliberately pair a device on your local network. Depending on the feature you choose, ROM files, saves, settings, layouts, cheats, screenshots, device names/IP addresses, pairing/trust state, input events and frame/audio streams can be transferred to that paired device. Local hosted-session and streaming paths use local sockets and HTTP; do not assume end-to-end encryption. DC Enhancements does not operate a public multiplayer or cloud-save service for these LAN sessions.

Permissions, Paid Play Distribution and Integrity

Bluetooth/Nearby Devices supports compatible controllers; Bluetooth scan is not used to derive physical location. Vibration supports haptics. Network and multicast permissions support local discovery and transfers with a device you deliberately pair. Nostalgience is sold as a one-time paid Google Play app. It has no ads, subscriptions or in-app purchases. Google Play Integrity may process installation, app-integrity and licensing information to prevent tampering and unauthorized copies. Access is granted only after a protected Play installation has passed the app's verification checks.

Legal Content Boundary

Nostalgience supports Game Boy, Game Boy Color and Game Boy Advance files you provide. It does not include, sell or provide commercial games, ROMs, BIOS files or ROM downloads. You are responsible for importing only content you are legally entitled to use.
