Nuclyx ("the game", "the app") is developed and published by Vishal Talekar ("we", "us"). This policy explains what the game does and does not do with your information. It covers the Android version distributed through Google Play.

Nuclyx has no accounts, no sign-in and no profiles, and the game contains no analytics of its own. We do not build a profile of you, and nothing you do in the game is stored on a server we control. The advertising SDK described in section 2 does collect data, for Google, and that section says exactly what. Three things reach the network, and only three: ads, purchases, and internet multiplayer — each is described below, and two of the three are handled entirely by Google.
Nothing that identifies you. The game asks for no email address, no phone number, no contacts, no photos, no location and no files.
The one thing you can type in is a display name — the name the game calls you by, asked once after the tutorial. It is optional (skip it and you play as your colour, such as "Blue"), it can be anything you like up to 10 characters, and it does not need to be your real name. It stays on your device, except in multiplayer, where it is shown to the other players (see section 4).
Two small files are written to the app's private storage on your own device. They never leave it, and uninstalling the app deletes them:
settings.cfg: Your preferences — sound on or off, board size, AI difficulty — and the display name you chose, if any.
entitlements.cfg: A single yes/no flag recording that you bought "Remove ads", so ads stay off when you are offline.
The free version of the game shows one interstitial advertisement between games, supplied by Google AdMob. It is never shown during play.
To serve those ads, the Google Mobile Ads SDK collects the following and shares it with Google, for advertising, analytics and fraud prevention:
Device and account identifiers — your device's Android Advertising ID (a resettable identifier) and app set ID
your IP address, which may be used to estimate your device's approximate location
app interactions — for example app launches, taps and ad views
diagnostic information — for example app launch time, hang rate and energy use
On Android versions that support it, the SDK may also use Android's Privacy Sandbox features (the Topics and attribution APIs), which are controlled from your device's own privacy settings.
The data is encrypted in transit. We do not receive, see, or store any of it. It is collected by Google as an independent controller under Google's own privacy policy: https://policies.google.com/privacy. You can review how Google uses data from apps that use its services at https://policies.google.com/technologies/partner-sites.
Your choices. On first launch in the European Economic Area, the United Kingdom and Switzerland, the game shows Google's User Messaging Platform consent form and honours your answer — decline, and you will see only non-personalised ads. Everywhere, Android's Settings → Privacy → Ads lets you delete or reset your Advertising ID and opt out of ad personalisation. And once you have bought "Remove ads" (below), the game does not start the ad SDK at all and shows no consent form — the ad SDK is only started when ads are switched on.
The game offers one optional, one-time purchase: Remove ads.
The entire transaction is carried out by Google Play Billing. Payment details — card numbers, billing address, and so on — are entered into Google Play, never into this game. We never see or receive your payment information. Google tells the app only whether the purchase exists, and the app records that single yes/no flag on your device.
Google's handling of the transaction is governed by the Google Play Terms of Service and Google's privacy policy.
Nuclyx has two ways to play with other people, and they behave differently.
Wi-Fi (local network). Devices find each other and exchange moves directly over your own Wi-Fi network. Nothing leaves that network and no server is involved. While you are hosting a game, your device announces it on that network — with your display name, so friends can tell which game is yours — and any device on the same Wi-Fi running Nuclyx can see that announcement. It stops when you stop hosting.
Internet (Beta). Devices connect through a relay server we operate on Cloudflare Workers. The relay's only job is to forward game packets between the players in one game, matched by the short game code you share with your opponent.
The relay stores nothing. It keeps no database, no logs of gameplay and no record of who played whom. When a game ends, nothing remains.
What passes through it is game data only — board moves, player colours, the game code, and each player's display name, so the other players in that game can see who they are playing. It carries no account, no email address and no device identifier.
As with any internet connection, your device's IP address is necessarily visible to the relay's infrastructure in order to route traffic. It is processed transiently by Cloudflare and is not recorded by us. Cloudflare's privacy policy: https://www.cloudflare.com/privacypolicy/.
Internet play is entirely optional. If you never open the Internet (Beta) tab, your device never contacts the relay.
Nuclyx is not directed at children under 13, and we do not knowingly collect personal information from them. The game is rated for a general audience, but because it serves advertising it is not enrolled in Google Play's Designed for Families programme. If you believe a child has provided personal information through the app, contact us at the address above and we will address it.
We do not sell your data, and we do not share it with anyone — because we do not hold it. The only third parties involved are Google (ads and payments) and Cloudflare (relay routing), each acting under its own policy as described above.
Since no personal data is stored on our systems, there is nothing for us to retain or delete. Data held on your device is removed when you uninstall the app. To reset the advertising identifier that Google holds, use Android's ad settings described in section 2.
Depending on where you live, you may have rights under the GDPR, the UK GDPR, the CCPA or India's DPDP Act — including the right to access, correct or delete personal data held about you, and to withdraw consent.
Because we hold no personal data, most such requests are best directed to Google (for advertising and purchase data) via https://policies.google.com/privacy. For anything concerning this app specifically, write to us at the contact address above and we will respond within 30 days.
You may withdraw advertising consent at any time by resetting it in Android's ad settings, or remove advertising entirely with the "Remove ads" purchase.
Traffic to the relay uses encrypted WebSocket connections (wss://). Ad and billing traffic is secured by Google's own SDKs. Local files are held in the app's private storage, which other apps cannot read. No system is perfectly secure, but as the game holds no personal data, the consequences of any breach are correspondingly limited.
If this policy changes materially — for example if the game begins collecting something it does not collect today — we will update the "Last updated" date above and publish the revised policy at this same address before the change takes effect in a released version.
