This policy explains what data Deadstop (the "App") collects, why, the legal bases we rely on, and your choices. The App has no account and no text input; we do not collect your name, email address, phone number or contacts. Providing data is not required to play, and we make no decisions about you based solely on automated processing that have legal or similarly significant effects.

Deadstop has no account system or server of its own. Your game progress stays on your device. Optional rankings use Apple Game Center, ads use Google AdMob, gameplay statistics use Google Analytics for Firebase (you can switch them off), and optional crash reports use Google Firebase Crashlytics.

Your progress stays on your device

Your personal bests, rating, round history, daily results, first-run guide progress, session count and preferences (sound, haptics, theme, gameplay statistics and diagnostics choices) are stored on your device and are not uploaded to us. Deleting the App removes its local data; device backups are controlled by your device settings. Google's SDKs also store on your device your ad consent choices, the Analytics app-instance identifier and any cached crash reports.

Optional leaderboards — Apple Game Center

The App offers World and Friends leaderboards run entirely by Apple Game Center. You can decline Game Center sign-in; the App works fully without it, but results earned while signed out are not ranked.

When you are signed in and earn a ranked result, the score is sent directly to Apple under your Game Center profile and shown publicly with your Game Center nickname. Apple handles it under Apple's privacy policy (https://www.apple.com/legal/privacy/); it is not sent to us. You can manage or sign out of Game Center in your device's Settings.

To stop one account's results being submitted as another's, the App reads the signed-in Game Center player identifier in memory while it is open. It does not store that identifier or add it to statistics or crash reports. A score that could not be sent yet is kept on your device, for the same Game Center account only, and retried when the App opens or returns to the foreground; a weekly score is dropped once its week ends.

Advertising — Google AdMob

The App is free and shows ads served by Google AdMob. AdMob and its partners may collect device identifiers (including Apple's advertising identifier, IDFA, only if you allow tracking, and other app- or device-scoped identifiers), approximate location derived from your IP address, ad interaction data, information about how you use the App, device information, and diagnostic and performance data used to operate and improve the advertising SDK.

In the current version every ad request is for non-personalized ads, which are chosen from context rather than your interests; Google may still use identifiers for frequency capping, aggregated ad reporting and fraud prevention. Where the law requires it (for example in the EEA, UK and Switzerland), Google's consent form asks for your choices before ads load, and Settings → Privacy choices reopens it. On iPhone, tracking also requires your permission through Apple's App Tracking Transparency prompt, which you can change in Settings → Privacy & Security → Tracking.

Gameplay statistics — Google Analytics for Firebase

What is collected. When gameplay statistics are on, the App sends events to Google Analytics for Firebase about how the games are played: which game, mode and difficulty you played; when a game starts and ends; results (for example a reaction time in milliseconds) and the number of clean rounds behind a ranked result; practice, Daily, Survival and promotion outcomes; goals and first-run guide completion; streak-freeze and Daily-retry offers; when an ad between games closes, with how long it stayed on screen as a coarse range only (ad_interstitial_shown with duration_bucket: 0–5 s, 5–15 s, 15–30 s, 30–60 s or 60 seconds or more); whether the optional Remove Ads card shown after an ad was displayed and whether you chose to buy or chose Not now (removeads_upsell, with no price or identifiers); and which screen was opened. Each ranked result also carries your device model (for example "iPhone 17 Pro"), the major iOS version and the App build, because touch and display latency differ between devices. The App measures how long each ad between games stays on screen and uses that time on your device to limit how much ad time you see (for example, by spacing ads out after a long one). Only the coarse duration range above is sent, and only when gameplay statistics are on.

Firebase adds, automatically: a random app-instance identifier created for this installation; standard events such as first open, session start, engagement time, app update and iOS update; the App version; device and operating-system information; and an approximate location (country/region) derived from your IP address. Google states that Google Analytics does not log or store IP addresses. Because Google's advertising SDK is also in the App, Google may automatically record ad events (such as ad requests, impressions, clicks and rewards) in the same statistics.

In-app purchase. One optional in-app purchase, Remove Ads. Apple processes the payment; we never receive your payment details or Apple ID. The App keeps a note on your device that you bought it, re-checked with Apple’s StoreKit on your device. If gameplay statistics are on, Google Analytics for Firebase may also record the purchase (product, price and currency) with its random app-instance ID; it is kept for 2 months like other statistics. It removes the ads shown between games; optional rewarded ads stay available. The Remove Ads card is shown by the App itself, not by an ad network; showing it sends no data beyond the event above, which is sent only when gameplay statistics are on.

We do not set a user ID or user profile, and we do not send your name, Game Center name or player ID, or anything you type (there is nowhere to type). Analytics in this App is built without advertising-identifier (IDFA) support and with vendor-identifier (IDFV) collection switched off. Google signals, ad personalization, data sharing with Google for its own purposes and links to Google advertising products are turned off for this App's Analytics property. We do not use gameplay statistics for advertising or to track you across other companies' apps or websites. The app-instance identifier makes these statistics pseudonymous, so we treat them as personal data.

Why. To calibrate the rating ladder and difficulty brackets against real results on real devices, and to see which games and features are used so we can fix and improve them.

When it starts and your choice. Build 41 and later: the App does not ask a separate statistics question. No gameplay statistics are sent before you finish your first game. Collection also waits for the startup consent checks to finish. Development builds do not collect gameplay statistics; TestFlight builds follow the same rules; their events carry a build-environment label (app_env), so beta data is kept out of the rating ladder.

Outside the EEA, UK and Switzerland, gameplay statistics are on by default after your first game, once the startup consent checks have finished. You can switch them off, or back on, at any time in Settings → Share gameplay stats. If you chose Not now or switched statistics off in an earlier build, that choice is kept.

Where Google's consent form applies to you in the EEA, UK and Switzerland, statistics are on only if you consent in that form to storing information on your device and measuring content performance; otherwise they stay off. Legal basis: your consent. You can withdraw through Settings → Privacy choices, or switch statistics off through Settings → Share gameplay stats.

If the App cannot determine which rules apply to you (for example on a first launch without a connection), including when a later consent read returns an unknown result, statistics stay off until the consent checks resolve and permit collection. Unless you have switched statistics off, completed-game results may wait temporarily in memory while these checks are unresolved and are sent only if collection is then permitted.

Earlier versions. Builds 37 to 40 kept gameplay statistics off unless you agreed: after your first game the App asked whether to Share or choose Not now, and you could also switch statistics on in Settings → Share gameplay stats. In the EEA, UK and Switzerland, those builds also required your consent in Google's form and asked only once it had been given. Choosing Share in that question also sent an event recording the answer. In build 36 and earlier, where Google's consent form applies to you (EEA, UK and Switzerland), statistics stay off unless you consent in that form to storing information on your device and measuring content performance. Elsewhere, statistics are on by default after your first game, and you can switch them off at any time in Settings → Share gameplay stats. If the App cannot yet tell which applies to you (for example on a first launch without a connection), statistics stay off.

Switching statistics off in Settings stops collection immediately and resets the Analytics app-instance identifier on your device, so if you switch them on again, they start as a new installation. If your device cannot save the choice, the App keeps statistics off for the current session, shows that it has not been saved, and retries while the App is running. You can also choose Save my choice now in Settings. If the App is stopped and restarted before the choice is saved, the previously saved choice (or, if none was saved, the default above) may apply; check Settings and retry saving your choice. Data already sent is not recalled; it is deleted on the schedule below.

Retention. Event-level Analytics data is kept for 2 months (the shortest Google Analytics setting) and then deleted by Google. Aggregated reports that identify no one (for example "median Lights Out result on iPhone 17 Pro, Hard") may be kept longer.

Who processes it. Google LLC, as our service provider and data processor, under the Google Analytics terms and Google's data processing terms. Firebase privacy information: https://firebase.google.com/support/privacy

Optional crash reports — Firebase Crashlytics

Share diagnostics starts off. You can switch it on in Settings to help us fix bugs and switch it off at any time. It stays off in development and preview builds. Crashlytics receives technical error and crash-stack information, your device model, operating-system and App versions, and an installation identifier used to operate crash reporting. We do not add your name, Game Center ID, custom user attributes or custom log messages. If gameplay statistics are also on, a crash report may include the most recent gameplay statistics events (as a short activity log before the crash), and the crash itself is counted in the statistics. StambaAI can access shared reports in Firebase to diagnose failures. Firebase may cache crash reports on your device while sharing is off; switching sharing on can upload those earlier reports as well as later ones. Shared reports are kept under Firebase's standard retention for Crashlytics.

What we do NOT collect

  • No name, email, phone number or contacts
  • No user ID, Game Center identity or advertising identifier in gameplay statistics
  • No precise GPS location; the App never asks for location access
  • No photos, files or camera data
  • No microphone access; the App plays sound but never records, and the microphone permission is removed from the App

How data is shared

Leaderboard scores go to Apple Game Center only when you are signed in. Advertising data is processed by Google AdMob and its partners under the choices described above. Gameplay statistics and crash reports are processed by Google as our service provider; we do not give them to advertising partners. We do not sell personal information. If you allow tracking, identifiers and ad data that AdMob processes for advertising may count as "sharing" for cross-context behavioral advertising under some US state laws; see "Your rights".

  • Ads: your consent through Google's consent form for storing/accessing information on your device and for personalized ads; for non-personalized ads, Google relies on the choices recorded in that form.
  • Gameplay statistics: your consent (see above).
  • Crash reports: your consent (Share diagnostics).
  • Storing progress and preferences on your device: necessary to provide the App you asked to use.
  • Answering your emails and requests: our legitimate interest in responding, and our legal obligations.

International transfers

Google processes data in the United States and other countries. For transfers from the EEA, UK and Switzerland, Google relies on the EU-US Data Privacy Framework (and its UK and Swiss extensions) and the Standard Contractual Clauses included in its data processing terms. Apple handles Game Center data under its own policy.

Children

Deadstop is a general-audience game and is not directed at children under 13, or under 16 where that is the age of digital consent in your country. We do not knowingly collect personal data from children. If you believe a child has provided data, contact support@stamba.ai and we will help.

Your rights

EEA/UK/Switzerland: you have the right to access, correct, delete, restrict or object to processing of your personal data, the right to data portability, and the right to withdraw consent at any time (Settings → Privacy choices where shown, Settings → Share gameplay stats, Settings → Share diagnostics, or your device's Tracking settings). Withdrawing consent does not affect processing before the withdrawal. You may lodge a complaint with your data protection authority.

United States (including California): you may have the right to know, access, delete and correct personal information and to opt out of its sale, "sharing" for cross-context behavioral advertising, or targeted advertising. We do not sell personal information, and gameplay statistics and crash reports are not used for advertising. To limit ad tracking, deny or turn off tracking in Settings → Privacy & Security → Tracking; if the App shows Settings → Privacy choices for your region, you can opt out there too. You can also email support@stamba.ai. We will not discriminate against you for exercising your rights.

Everyone: deleting the App removes its local progress and preferences. Switching gameplay statistics or diagnostics off stops future collection but does not recall data already sent. Because we attach no name or account to statistics or crash reports, we may not be able to find your records; email support@stamba.ai with your request and we will respond as applicable law requires.

Data retention and security

Local progress and preferences remain until you delete the App, subject to your device backups. Gameplay statistics: event-level data 2 months, then deleted by Google; aggregated reports that identify no one may be kept longer. Crash reports: Firebase's standard Crashlytics retention. Apple and Google manage their own advertising and Game Center data and retention. Connections use HTTPS and the platform's cryptography.

Changes

We may update this policy; material changes will be shown by a new effective date on this page, and where the law requires it we will ask for your consent again.
