Privacy Policy

Effective date: 7 November 2026
App: K-EMU (Android package com.tinysol.kemu), version 1.0.0 and later
Developer: Tiny Solution

This policy explains what K-EMU does with data. It is written from what the app actually does, and it will be updated whenever that changes.

Summary

• K-EMU keeps your games, saves, settings and controls on your device.
• No account, no sign-in and no personal information is asked for.
• No ads, no in-app purchases and no tracking.
• When you are online, K-EMU asks Google's Firebase service for a small configuration file, and it sends crash reports and performance data to Google's Firebase services. This is always on and cannot be turned off inside the app.
• K-EMU does not send your games, saves or settings to us or to anyone else.

Data stored on your device

K-EMU stores the following in its private app storage and in the folder you choose. None of it is uploaded.

• Folder access: the games folder you pick with the system folder picker. K-EMU keeps that permission and reads only that folder.
• Library data: a list of the games found in your folder, favorites and recent games.
• Settings: language, appearance, display mode, sound, vibration, turbo and rotation choices.
• Save data: quick saves and battery saves for the games you play, with small preview pictures.
• Controls: your touch layout and your gamepad and keyboard button mappings.

Your games are your own files. K-EMU reads them to play them and does not copy, upload or share them.

Data sent to service providers

K-EMU uses Firebase, a service of Google LLC, to keep the app running well. Google acts as our processor and handles this data for us under the Firebase terms. Each item below is collected automatically and is always on; K-EMU has no setting to turn it off.

• Remote Configuration (when the device is online): at app start, K-EMU downloads a small configuration file from Firebase. It says whether the service is under maintenance and the lowest app version that may run, so we can ask you to update. To do this, the request includes the app id, the platform (Android) and a Firebase installation ID, a random identifier created by Firebase for this install.
• Crash reports (Firebase Crashlytics): when the app crashes, it sends the crash stack trace, the device model, the Android version, the app version, the state of the app at the time of the crash and the Firebase installation ID.
• Performance data (Firebase Performance Monitoring): K-EMU sends performance traces such as app start time, screen rendering speed and network request timing, together with the device model, Android version, app version, the country (derived by Google from the IP address, not from your location) and the Firebase installation ID.

None of this contains your games, game file names, saves, settings or any personal details you type. It does not include your advertising ID, location, contacts, photos, microphone or camera data. We use it only to keep the app working (to fix crashes, to measure and improve speed, and to show a maintenance or update notice) and not for advertising.

Crash data is kept by Firebase Crashlytics for up to 90 days. Performance data is kept for the period stated in Google's Firebase privacy information. Learn more in Google's privacy information for Firebase at https://firebase.google.com/support/privacy and the Google Privacy Policy at https://policies.google.com/privacy.

When the device is offline, K-EMU still plays your games normally: it simply cannot download the configuration, so no maintenance or update notice is shown, and crash and performance data is sent the next time the device is online.

Network access

The app declares network permissions for two purposes. The first is the Firebase services described above, which reach Google over the internet. The second is a local Wi-Fi controller feature, which lets a phone act as a controller for a device on the same network. When the local feature is used, it talks only to a device on your local network.

What we do not do

• We do not sell or rent your data, and we share it only with Google as described above.
• We do not show ads.
• We do not track you across apps or websites.
• We do not collect your precise or approximate location. Google derives only a country from the IP address of the connection.
• We do not collect your advertising ID.

Your choices and deletion

The games, saves and settings K-EMU stores are on your device. To delete them, remove a game's saves from the Library, remove the folder from the Library settings, clear the app's storage in Android Settings, or uninstall the app. We hold no copy of them.

The Firebase data described above is tied to a random installation ID, not to your name. K-EMU has no account, so we cannot look up data by person. Clearing the app's storage or uninstalling the app resets the installation ID, and Firebase deletes crash and performance data after their retention periods (up to 90 days for crash data). To ask about this data, contact us at the address below.

Children

K-EMU is not directed at children under 13 and does not knowingly collect personal data from anyone. The only data it sends is the crash, performance and configuration data described above, which is not linked to a name or account.

Security

Your games, saves and settings stay in the app's private storage on your device, protected by Android's app sandbox. Data sent to Firebase is encrypted in transit.

Changes to this policy

If the way K-EMU handles data changes, we will update this page and the effective date, and the updated text will ship in the app under Settings, About.
