Privacy Policy

Last updated: 9 November 2026

Mitosis: Cell Arena ("Mitosis", "the game") is made by Catapult Consulting, LLC. This policy explains what the game stores, why, and how to remove it. It applies to the iPhone and Android apps and to the website, mitosisgame.com.

What the game stores

A device identity. When you first play, the game creates a random identifier on your device and sends it to the Mitosis server. It is used to keep your wallet (ATP balance and skins), your rating, your battle pass progress and your run history together. It contains nothing about you and is not shared with anyone.

Account sign-in (optional). If you choose Sign in with Apple or Sign in with Google, Apple or Google sends the game a signed token identifying your account. The server verifies that token and stores the account identifier, and the email address if you share it, so your wallet, skins and rating can follow you to other devices. The game never sees your password. Apple's "Hide My Email" relay addresses are supported.

Purchases. ATP packs are sold through the App Store and Google Play. The store processes the payment; the game receives only a signed purchase receipt, which the server verifies with Apple or Google before crediting ATP. The server keeps the transaction identifier to prevent the same purchase being credited twice. The game never sees your payment details.

Gameplay. Run results (how long you survived, cells absorbed, placement, chosen name) are sent to the server to pay out ATP, update your rating, add XP toward your level and keep your lifetime stats and rank trophies. The display name you type, and the font you pick for it, are shown to other players in live rounds, on the leaderboard and to your friends.

Nearby play (iPhone app). If you switch the lobby to Nearby, the app uses Bluetooth and peer-to-peer Wi-Fi (Apple's local network permission) to find other phones running Mitosis close by. While you play, your display name, chosen look and the positions of your cells go directly to those phones and nowhere else; nothing from a nearby game is sent to the server or stored, and nearby games do not pay ATP or change your rating. Turning Nearby off disconnects at once.

Game recording (iPhone app, off unless you turn it on). With Settings › Record games on, the app records each of your games with iOS screen recording (iOS asks you first) and adds the video to your Photos library (iOS asks for permission to add photos). Recordings stay on your phone; the app never uploads them or reads anything else in Photos.

Connection quality. While you play online, the game measures how long messages take to reach the server and back, how many never come back, and how smoothly it draws. Every few minutes it sends those numbers, the app version and your device's time zone (for example "Europe/London") so we can see where a closer server would help. These reports carry no player identifier, and the server does not store IP addresses with them.

Player counts. The server counts how many games are connected to it at a time, whether each came from the website or the iPhone or Android app (from the browser details every connection sends), and whether it is in a game or the menus. It keeps only these totals, minute by minute for 24 hours; nothing that identifies a player or a device is stored.

Diagnostics. If the app crashes or stalls, a technical report (device model, OS version, app version and a stack trace) is sent to the server so the problem can be fixed. Reports contain no personal information.

Website visits. mitosisgame.com is served through Cloudflare, which counts page views with Cloudflare Web Analytics: the page visited, the referring site, the country, and the browser and device type. It uses no cookies and no visitor identifier, and Cloudflare does not use it to track you across sites. The apps do not use it.

What the game does not do

• No advertising, no ad identifiers, no advertising networks.
• No tracking across apps or websites, and no sale of data.
• No analytics SDKs; the only server the apps talk to is the Mitosis game server, plus Apple's and Google's services for purchases and sign-in.
• No access to contacts, location, camera or microphone, and no reading of your photos (the app only adds the games you choose to record). The local network is used only for Nearby play, and only after you choose it.

Where data is kept

The Mitosis server stores wallets, accounts, run results, purchase identifiers and diagnostics. It is operated by Catapult Consulting, LLC. Data is kept for as long as the account or device identity exists.

Deleting your data

• Delete account in the game (Profile › Account › Delete account, or Settings › Account & data) permanently deletes your account from the server straight away: rating, XP and level, lifetime stats and trophies, ATP, skins, battle pass progress, run history, display name and its font, and any Sign in with Apple or Google link. Records of App Store and Google Play purchases are kept only as anonymous transaction ids, so a purchase cannot be credited twice; they are no longer linked to you. The game then clears its data on your device and starts you fresh.
• If you signed in with Apple, you can also stop using your Apple Account with the game in iPhone Settings › your name › Sign in with Apple.
• Sign out in the game's Profile (tap your name on the home screen) detaches your device from your account and gives the device a fresh wallet.
• Deleting the app or clearing the website's site data removes the device identity from your device; a new one is created next time you play.
• If you can no longer open the game, ask for deletion at https://mitosisgame.com/delete-account, by email to [email protected], or by opening an issue at https://github.com/rowanmorse-demo/mitosis/issues. Those requests are completed within 30 days.

Children

The game is suitable for general audiences and does not knowingly collect personal information from children under 13. Sign-in and purchases are optional and go through Apple's or Google's own systems.

Changes

If this policy changes, the date above is updated and the new version is published at the same address.
