Privacy Policy

Match KO · Yoshiba Productions · Effective 5 August 2026

This policy explains what Match KO ("the game", "we") does and does not do with information when you play. It applies to the Android app published by Yoshiba Productions under the package name com.yoshibaproductions.matchko.

Information we collect

No personal information. We do not collect, transmit, sell, or share anything that identifies you. The game contains no advertising and no ad-tracking software. It does not ask for your name, email address, phone number, contacts, location, photos, or microphone, and it never reads your advertising identifier.

The only data the game does collect is pseudonymous technical data — crash reports and gameplay telemetry tied to a random identifier instead of to you — described in detail under Crash reports and telemetry below.

There is no Match KO account, and playing never requires a sign-in of any kind. The game offers an optional Google Play Games sign-in: today it does exactly one thing — it puts your Play Games name on the menu nameplate, on your own screen — and when the daily leaderboard arrives it will also be how you compete (see What's coming). Declining costs you nothing but the nameplate. Sign-in is Google's flow, governed by Google's Privacy Policy; nothing Match KO sends includes your name or any account identity — only technical reports filed under a random identifier.

Information stored on your device

So that the game can remember your progress between sessions, it saves the following to your device's local app storage (Android shared preferences). This information stays on your device and is not visible or accessible to us:

• Your settings — music, sound effects and master volume, difficulty, haptics and notification preferences
• Your progress — arcade run state, which fighters you have unlocked, and achievements earned
• Your record — wins, losses and draws
• Your cosmetics — which items you own and which are equipped
• Daily Fight results, so the game knows which days you have already played
• Whether you have seen the tutorial and one-time tips

Deleting the app removes this data. You can also clear it at any time through Android's Settings → Apps → Match KO → Storage → Clear data.

Android backup

Match KO uses Android's standard Auto Backup feature so your progress survives reinstalling the game or moving to a new phone. When this is active, Android copies the saved data described above into your own Google Drive backup, or transfers it directly during device-to-device setup.

This backup belongs to you and your Google account. It is handled entirely by Google and the Android operating system — we have no access to it and cannot read, retrieve, or delete it. It is governed by Google's Privacy Policy and by your device's backup settings, which you can turn off in Android under Settings → Google → Backup.

Crash reports and telemetry

Match KO collects two kinds of technical data, and nothing else:

• Crash data — if the game crashes or stops responding, it sends a report describing what the software was doing when it broke: a technical stack trace plus basic device details such as the device model, Android version, and game version.
• Gameplay telemetry — statistics about how the game is played, for example which modes and fighters are picked, how fights end, and how long sessions last.

This data is pseudonymous: it is filed under a random identifier created when the game is installed, not under your name, email address, or any advertising ID — the game never has any of those. IP addresses are not stored with it and it contains no location. It can tell us that some device crashed twice or finished an Arcade run; it cannot tell us who you are, and we make no attempt to find out. The identifier is visible in the game's settings as your Support ID, and everything the game sends — telemetry and crash reports alike — can be switched off entirely on the same settings screen.

These reports are processed for us by PostHog and Sentry, both running on EU servers; each handles this data under its own privacy policy as well as this one. We use it only to find and fix bugs, balance fighters, and decide what to improve. It is never sold, never shared for marketing, and never used for advertising.

Separately from the game's own reporting, when an app crashes or stops responding on Android, the operating system and the Google Play Store may also report that to Google automatically — this happens for every app on Google Play, whether or not the developer asks for it, and it depends on your device's own usage-and-diagnostics settings. Through Google Play we can see aggregated crash statistics and anonymous technical stack traces for Match KO. You can control that channel at the system level under Settings → Google → Usage & diagnostics, and it is covered by Google's Privacy Policy.

Advertising and purchases

Match KO contains no advertising — not now, not ever. No ad SDKs, no ad placements, and no advertising identifier is read or used. There is no energy system, no loot-box or gacha mechanic, and no invented gem currency, and there never will be.

Today there are also no in-app purchases — the in-game shop says COMING SOON and means it. If it opens, it will sell cosmetics only, at real prices, with nothing that affects combat and no way to buy the titles players earn. Payments would be handled by Google Play, and we would never see your payment details. The specifics live under What's coming, and this policy gains a full purchases section before anything is sold.

Children

Match KO is not directed at children under 13, and we do not knowingly collect personal information from anyone — including children. The only data the game collects is the pseudonymous technical data described above, which does not identify anyone of any age.

Permissions

The game requests no sensitive Android permissions. It does not need internet access to play — the network carries only what this policy describes: the crash reports and telemetry above, Google's optional sign-in if you use it, and, when the leaderboard ships, the scores you choose to submit — and it does not read your storage, camera, contacts, or location.

One prompt you may see: Android will ask you to allow notifications if you turn them on in the game. Notifications are created on your device — there is no push service — and they exist for the optional Daily Fight reminder and occasional news about new content, such as new cosmetics: a heads-up, never a guilt trip. Declining changes nothing else about the game, and you can switch them off at any time in the game's settings or Android's.

Your rights

Because we hold no personal data about you, there is nothing we could look up by your name or email — the crash and telemetry data we receive is filed under a random identifier. That identifier is shown in the game's settings as your Support ID: send it to us and we can find and delete everything filed under it. You remain in full control of the local data described above: uninstall the app or clear its data to remove it. If you have questions about this, contact us at the address below.

What's coming — decided, not yet live

Match KO's roadmap is written down before it ships — in the game and here. None of the following is live today. Each will be described in this policy in full, present-tense detail, with the effective date changed, before the build carrying it reaches anyone:

• An optional daily leaderboard — if you choose to compete, the Play Games sign-in described above is how you enter: the game submits your platform display name and that day's score, which appear in public standings. Scores are submitted only by your explicit choice — pull, never push — and declining leaves everything else playable and the standings viewable. Signing in will also allow optional cloud save of your progress in your own Google account.
• A cosmetic shop — purchase-only cosmetics such as skins, taunts, and prestige poses, at real prices, through Google Play billing. No loot boxes, no gem currencies, no gameplay advantages, and titles stay earned-only, forever.
• An optional Daily Fight reminder — one quiet notification a day, created on your device behind an opt-in toggle and Android's own notification permission.
• iOS — after the Android launch, with this policy updated for the App Store's equivalents at that time.

Whatever ships, four things do not change: no advertising, ever. Nothing about you sold or shared, ever. No advertising identifiers, ever. And anything online stays optional — the fight itself will never require an account or a connection.

Changes to this policy

If a future version of Match KO ever collects anything beyond what is described here, we will update this page and change the effective date above before that version is released. The What's coming section already lists everything on the roadmap that will touch this policy, so an update here should confirm what you have already read, not reveal it. Material changes will be described here rather than made quietly.
