Privacy Policy

Overview

Numverse ("Numverse", "we", "us", or "our") is a free mobile app from Echozat that bundles number games: 2048, Match Ten and Sudoku, with a daily puzzle for each. This Privacy Policy explains what information the app handles and the choices you have.

Numverse has no sign-in, no account and no user profile. We do not ask for your name, email, phone number, contacts or location.

By using Numverse, you acknowledge that you have read and understood this Privacy Policy. If you do not agree with our practices, please discontinue use of the app.

What Stays on Your Phone

The following is stored only in the app's local storage on your device:

• Settings: Theme, language, sound, haptics, timer and game options, and your daily reminder choice.
• Saved games: The current state of any game in progress.
• Stats: Games played, wins, best scores and times.
• Daily results and streaks: Which daily puzzles you have completed.
• App flags: Things like whether you've seen a tip, and a cached copy of whether ads have been removed.

None of this contains personal information. On Android, the app's data is excluded from automatic cloud backup, and the app has no cloud sync of its own, so your progress does not move to a new phone automatically. Resetting stats or clearing app data deletes it.

What Leaves Your Phone

Like any internet request, these connections naturally expose your IP address to the service receiving them. Your saved games, stats and what you enter on the board are never sent.

Ads & Consent

Numverse is free and supported by ads from Google AdMob. We keep ads out of the way of play:

• Banners appear only on menu screens (Home, Daily and Stats), never on a game screen.
• Full-screen ads appear only at natural breaks between games, never in the middle of a move, at launch, or during your first couple of games.
• Rewarded videos for extra hints or undos are always optional and always explained first.

AdMob may use your device's advertising ID to serve and measure ads, under Google's own policies. In regions where the law requires it (such as the European Economic Area and the UK), Google's consent form is shown before ads are initialised. If you decline, you see non-personalised ads. You can reopen the form any time from Settings, then Privacy choices, and you can reset or limit your advertising ID in your phone's system settings.

If you buy "Remove ads", banners, full-screen ads and rewarded videos are removed.

Anonymous Analytics

We use Google Firebase Analytics to see, in aggregate, which games are played and where players get stuck, so we can balance difficulty, tune ad frequency and decide what to build next. We collect a small set of events, such as:

• A game started or ended, and which game it was.
• A hint or undo was used.
• A rewarded video was offered or completed, or an interstitial ad was shown.
• The Remove ads sheet was viewed, or a purchase or restore happened.
• A daily puzzle was completed, with the streak grouped into a range (1, 2 to 6, 7 to 29, or 30 or more).
• The screen you are on, as a route name only.

We never log board contents, the digits you enter, or anything personal. We have set Firebase so that it does not collect your advertising ID or other device-level advertising identifiers, and so that analytics data is not linked to advertising. Analytics is disabled in development builds.

Purchases

"Remove ads" is a one-time purchase handled by Google Play or the App Store. We use RevenueCat to check that you own it, using an anonymous identifier and the store receipt. We never see your payment details, name or email through this process. "Restore purchase" in Settings re-checks your purchase for your store account.

Daily Reminder & Permissions

Numverse asks for no permissions to install or play. The only permission it can request is notifications, and only if you choose to turn on the optional daily reminder.

• The reminder is off by default. It is offered once, after you complete your third daily puzzle, and you can change or turn it off in Settings.
• It is a local notification scheduled on your phone ("Today's puzzles are ready."). No push service or server is involved, and it contains no marketing.
• The app does not access your camera, microphone, contacts, photos or location.

What We Never Do

• We never require an account, so there is no profile of you to build.
• We never store or collect your name, email, phone number or location.
• We never sell your data. No data brokers, no third-party data sales, of any kind.
• We never log what you play on the board in analytics.
• We never send marketing notifications.

How We Share Data

We do not sell, rent, or trade your data. Data reaches a third party only in the situations listed in Section 3: Google (AdMob ads and Firebase Analytics) and RevenueCat (purchase verification).

If you choose to share a daily result, it is a plain-text message (for example, the game, date and difficulty) sent through your phone's own share sheet, and you decide where it goes.

We may disclose data if required by law, regulation, or court order, or to protect the rights, property, or safety of Numverse, our users, or the public.

Data Retention

• On-device data: Kept on your phone until you reset stats, clear the app's data or uninstall it. We hold no copy.
• Analytics events: Held in aggregate form by Firebase under its retention settings. They are not tied to a name, email or account.
• Ad and purchase data: Held by Google and RevenueCat under their own policies.

Your Rights & Choices

To make a request, email us at hello@echozat.com with the subject line "Numverse Privacy Request". We will respond within 30 days.

Security

• Your game data is stored in the app's private storage, protected by your phone's operating system.
• Connections to Google and RevenueCat use encrypted (HTTPS) connections.
• Payments are handled entirely by Google Play or the App Store; we never see card details.

No method of storage or transmission is 100% secure. While we rely on your device's own protections and our providers' security practices, we cannot guarantee absolute security.

Children's Privacy

Numverse is a general-audience puzzle app and is not designed for children. It is rated for a general audience of 12 and over because of its ads. We do not knowingly collect personal information from children, and the app has no accounts, chat or user-generated content. If you believe a child has used the app in a way that concerns you, please contact us.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. The "Last Updated" date at the top of this page always reflects the most recent revision. Continued use of the app after a revised policy is posted constitutes acceptance of the changes.
