Privacy Policy for Pulse

Last updated: November 1, 2026

Pulse (`com.cginsolution.pulse`) is an Android arcade game published by **CGIN Solution**. This policy explains how the game and the services it uses handle information. For privacy questions, contact **CGINSOLUTION@gmail.com**.

## Information stored by the game

Pulse does not require an email address, password, or social account to play. On first launch, the game assigns a player name that you can change in Settings. The game saves that name, your scores, game counts, collected orbs, daily challenge progress, unlocked and selected skins, and control and audio settings in app storage on your device. Depending on your Android device and backup settings, Android may back up and restore app data.

## Online leaderboard

If you complete an Endless run, Pulse may use Firebase Authentication to create an anonymous account and Firebase Realtime Database to store your player name, best Endless score, and best special-mode score. The anonymous account does not require your email address or password. Nakama stores your Online Ranking rating and win/loss totals; rating changes depend on both players' ratings and the match result. The ranking pages show player names, scores or ratings, and ranks. Pulse does not send your local settings, contacts, precise location, or advertising ID to the rankings.

## Online duel

If you choose **Online Duel**, our Nakama server finds your opponent, creates the match room, relays live movement and gameplay events, and stores your Online profile, rating, wins, and losses. Nakama receives a generated app-install identifier for device authentication and relays each player's in-game ID, display name, skin, movement, and gameplay state to the opponent. Finished match rooms are kept briefly so both players can see the result. Your Google email address is not displayed to other players or included in ranking records. Firebase is used for cloud progress and the separate Endless leaderboard; Nakama can securely read your old Firebase duel record once to migrate it to your Online profile.

## Optional Google account linking

You can optionally link the anonymous account to your Google account from Settings. Google and Firebase process the account identifier and basic profile information needed to authenticate you. Pulse uses this link to keep your Firebase cloud save and Endless scores, and to reconnect your Nakama Online account, when you change or reinstall your device. Your Google email address is not displayed to other players.

## Advertising and third-party data

Pulse uses our self-hosted Nakama service to authenticate game clients and relay live online-duel data. Network connections also expose standard connection details such as your IP address to the server. Pulse uses Google AdMob to show banner ads on menu screens, occasional interstitial ads after runs, and optional rewarded ads for a revive or a skin unlock. The Google Mobile Ads SDK may automatically collect and share your IP address (which can indicate approximate location), app and ad interactions such as launches, taps and video views, diagnostic information, and device or account identifiers such as the Android advertising ID or app set ID. Google uses this information for advertising, measurement, analytics, and fraud prevention. Google and its advertising partners may process this information under their own policies. Pulse does not receive or store your advertising ID in its own game-progress storage.

Read [Google's advertising privacy information](https://policies.google.com/technologies/ads) and [Google's Privacy Policy](https://policies.google.com/privacy) for details about Google's practices and controls.

## Google Play features

If you choose the **Rate Us** option, the game opens its Google Play listing. Google Play handles any review you submit under Google's policies. Pulse does not receive the text of your review through this feature.

## Why information is used

Local progress and settings let the game remember your scores, unlocks, daily challenge status, and preferences. Firebase stores cloud saves and Endless scores. Nakama authenticates players, runs Online matchmaking and matches, relays realtime duel data, and stores the Online ranking. Ad-related data processed by Google supports ad delivery, measurement, analytics, and protection against invalid activity. The game uses internet and network-state access for rankings, duels, and ads. Pulse does not request access to your contacts, camera, microphone, or precise device location.

## Your choices

You can clear local game data in Android's app settings or uninstall Pulse. Clearing data resets your local scores, unlocks, player name, and preferences. To request deletion of your Firebase leaderboard data and Nakama game account, contact us at CGINSOLUTION@gmail.com with your player name and, if linked, the Google account used to save progress. Android backups, if enabled, are controlled by your device and Google account settings. You can manage available advertising controls, including the Android advertising ID, in your device or Google account settings. Optional rewarded ads are initiated by you; other ad formats may appear as described above.

## Retention and security

Local game data remains in the app's storage until you clear it or uninstall the game, subject to any Android backup that you have enabled. Firebase cloud saves and Endless leaderboard records remain until we delete them or process a valid deletion request. Nakama retains Online profiles and ratings until the associated game account is deleted; finished match rooms are temporary. Google's retention practices for information processed by Firebase, AdMob, and Google Play are described in Google's policies. The game uses Android's app-private storage for local progress. Google states that the Mobile Ads SDK encrypts the data it transmits in transit.

## Children

Pulse does not ask players to create an account or submit personal details. If you are a parent or guardian and have a concern about a child's information in connection with the game, contact us at **CGINSOLUTION@gmail.com**. Advertising data may be processed by Google as described above.

## Changes to this policy

We may update this policy if the game or its data practices change. The updated version will show a new “Last updated” date. Material changes will be reflected in the policy available in the app and on the public page linked from Google Play.
