Effective date: 27 September 2026

This policy describes what the app actually does with data, based on its real technical behaviour. Game Mode Pro: Launcher & HUD is a paid app: it shows no ads and does not share your data with advertisers. There is no advertising SDK in the app.

1. Information collected automatically

The app has no account system and never asks for your name, email address, or contacts. These Google services inside the app process limited technical data:

• Google Analytics for Firebase — anonymous usage events (screens opened, and which features are used, such as turning on the Game HUD or Game Mode) plus general device information (model, operating system version, country, app version) and an app-instance identifier. It does not receive the names of your games or your device readings. Purpose: understand which features are used so they can be improved. Recipient: Google.

• Firebase Crashlytics — when the app crashes or logs an error it sends a crash report: the stack trace, device model and operating system version, and a diagnostic log of recent app events. It is not used to track you and does not receive your game names or readings. Purpose: find and fix crashes. Recipient: Google.

• Google Play Billing and Google Play In-App Review — handle the optional VIP subscription and the optional review prompt entirely inside Google Play. Your card number, bank details, and billing address never reach the app or the developer. The app only learns whether a subscription is currently active. Recipient: Google.

The developer runs no servers of their own and receives no directly identifying information about you — only the aggregated statistics and crash reports that Google provides.

The network measurements described below also leave the device, but they carry no personal data: latency checks go to Google Public DNS (8.8.8.8), and the Regions tab of Network check briefly connects to public Amazon Web Services endpoints. Like any internet connection, those servers see your device's IP address; the app sends them nothing else and learns nothing about you from them.

2. Information that stays on your device

Everything the app measures or records for you is stored locally and is never uploaded:

• your Game Launcher list — which installed apps you marked as games;

• play-session records made while Game HUD is on: playing time, free memory, battery level and temperature, network latency to a public DNS server, and screen refresh rate. Each record also keeps a short network summary: the network type (Wi-Fi, mobile data or none), the strongest and weakest Wi-Fi signal strength and its band, the highest total data rate of the whole device (one number for all apps together, never per app), and the moment the network changed or dropped, if it did. The app does not read the Wi-Fi network's name, the router's address, or your location;

• your settings — HUD layout and alert levels, Game Mode options (including any game's own Game Mode), notification preferences, and the sound and vibration switches of Reflex Trainer and Test kit;

• your Reflex Trainer (Robot Range) results — on each range your best score and stars, your latest average and the history of recent runs, and the taps of your record run so the lobby can play its best seconds back. They are kept only so the screen can show your own progress; the Reset scores button on that screen deletes all of them;

• app-usage totals read from Android's usage statistics, used only to sort your game list;

• your Network check history — the last twelve checks, each with the average, lowest, variation and how many samples did not answer. Each check sends small round-trip requests to a public DNS server; no personal data is sent with them, and the results are written only to this device.

• two further Network check tabs, run only when you tap them, whose results are shown on screen and not saved: Wi-Fi · 4G/5G measures the same round trip over Wi-Fi and over mobile data at the same time (Android opens the mobile data path for those few seconds and the app releases it right after; it uses a tiny amount of mobile data), and Regions briefly opens and closes a connection to public Amazon Web Services data centers in 13 regions to time the handshake. Neither sends any personal data.

• nothing from the Test kit: the touch rate, touch points, display modes and controller input it shows are read live while that screen is open and are not saved.

Backing up and restoring your session log

You can save your play-session records to a file and load them back later. Both directions use Android's own file picker: you choose the file and where it goes, the app writes or reads only that one file, and no storage permission is requested or held. The file contains the same session records described above and nothing else — no account, no identifier, no contact data.

Nothing is sent anywhere: the file is created on your device, and where it travels afterwards (a cloud drive, a chat message, another phone) is entirely your decision, outside this app and outside this policy. Restoring adds sessions from the file and never deletes what is already on the device; a session that is already there is not duplicated.

Game Coach: the model runs on your device

Game Coach reads the play-session records listed above and fits a small statistical model to them — the minute your sessions with a game tend to become uneven, how the battery and temperature move over a session, which time of day and network type your sessions held up best on. All of that happens inside the app on your phone, using only records this app made on this phone.

No session, no model and no result is uploaded, shared, or sent to us or to anyone else. There is no account and no server behind this feature. Because it is fitted only to your own history, its output is an estimate rather than a guarantee, and it does not change your game or your device.

The same records feed the home screen widget and the optional reminders shown while you play. Both read only what is already stored on this device. Clearing the app's data removes the records, and with them everything Game Coach had learned.

Clearing the app's data or uninstalling the app deletes all of it.

3. Permissions and why they are used

Each permission is requested only at the moment you turn on the feature that needs it, with an explanation of why that feature needs it. Nothing is requested at first launch.

• Display over other apps — draws the floating Game HUD panel on top of your game. The overlay only draws; it does not capture, record, or read your screen, and it cannot see anything inside your game.

• Usage access — lets the app tell which app is in the foreground, so the HUD appears when a game opens and disappears when you leave it, so Auto Game Mode can switch on and off, and so your game list can be sorted by play time. These readings stay on the device.

• Do Not Disturb access — Game Mode can silence notifications while you play and restores your previous setting when you turn it off. Used only if you enable it.

• Modify system settings (WRITE_SETTINGS) — only for the optional brightness lock in Game Mode: adaptive brightness is switched off while you play and switched back on when Game Mode ends. Requested only when you turn that option on; nothing else in the app uses it.

• Notifications — the ongoing Game HUD status notification (which carries a Stop button so you can switch the HUD off at any time) and the optional notifications you enable in Settings.

• Run at startup — restores the Game HUD service after a reboot if you had it switched on.

• Internet and network state — measures network latency against a public DNS server for the HUD, and lets the Google services above work. The latency test sends no personal data.

• Wi-Fi state (ACCESS_WIFI_STATE) — reads the signal strength and band of the Wi-Fi you are connected to, for the HUD session summary and the Wi-Fi · 4G/5G tab. It does not read the network name or anything tied to your location. Granted at install; nothing is asked.

• Change network connectivity (CHANGE_NETWORK_STATE) — used only by the Wi-Fi · 4G/5G tab, to ask Android for a mobile data path while you are on Wi-Fi and to give it back as soon as the measurement ends. It does not switch your phone's network or any other app's connection. Granted at install; nothing is asked.

4. Purchases

The app is sold on Google Play, and the optional VIP subscription is billed by Google Play. The app never sees your card number, bank details, or billing address. Manage or cancel a subscription in Google Play → Payments & subscriptions.

5. Children

The app is not directed at children under 13 and does not knowingly collect personal information from them. If you believe a child has provided personal data through the Google services listed above, contact us at the address below and we will help to have it removed.

6. Retention and deletion

Data on your device stays there until you clear the app's data or uninstall the app; both remove it completely. A backup file you exported yourself is not touched by either: it lives wherever you saved it, and deleting it is up to you. Data processed by Google (analytics, crash reports, billing) is retained under Google's own policies and is not accessible to the developer in a form that identifies you. To ask about data held about you, email us at the address below.

7. Your rights

Depending on where you live, you may have rights to access, correct, or delete personal data. Because the developer holds no directly identifying data about you, most of these rights are exercised against Google for the services listed above. For anything else, email us and we will help.

8. Security

Analytics, crash reports and billing data leave the device only to Google, over encrypted connections; the network measurements carry no personal data. No method of transmission is completely secure, but the app keeps the risk small by leaving your measurements and settings on the device.

9. Changes

Changes to this policy will be posted on this page with a new effective date. Material changes will also be reflected in the app's Google Play listing.
