Privacy Policy

Who we are and what this covers

Sudokuzy: Daily Sudoku is provided by MATRIXBREACH INNOVATIONS (OPC) PRIVATE LIMITED (“MatrixBreach”, “we” or “us”). Privacy questions can be sent to support@matrixbreach.com. The Android package is com.matrixbreach.sudoku.

This notice distinguishes information processed locally by the game, visits to matrixbreach.com, voluntary support emails and operating-system/platform services. Local processing is not the same as sending information to us.

Information saved on your device

Sudokuzy saves information locally to resume your puzzle, record progress and remember your preferences:

• Puzzle entries, manual notes, the active game and undo/redo history.

• Elapsed time, hint and other assistance records, and completion history.

• Daily dates, completed-day markers, stars, streak-related records and awards.

• Settings, independent learning/guide progress, lesson resume/completion/replay state, tutorial completion and tutorial-audio preferences, welcome/Terms acceptance version, optional Sudoku experience choice and a locally saved age band (13 or younger, 14–17, or adult). In the 1.0.13 update, a calendar-based birth-date picker replaces text entry. The selected birth date is used only to calculate that band and is not saved; no full birth-date database or age-tracking server is created.

• Virtual coin balance, saved hints, hearts in the active puzzle, any saved heart from an interrupted reward, individually unlocked levels and saved level-ad credits, hint resource history and challenge-trail completion records.

• Bug-report and contact drafts you enter, stored locally until you clear them or delete local progress.

Virtual coins, hints and hearts are active local game resources. New profiles receive 3,000 coins once. There is no complimentary hint allowance. Saved hints come from optional rewarded ads or earned virtual coins. A visible locked ordinary level can be opened early for 25,000 earned coins or two optional rewarded ads; the first earned ad credit is saved and an unlock applies only to the selected level. Each puzzle starts with three hearts. After they are used, the player can spend earned coins or choose an optional rewarded ad to restore one heart; retrying the puzzle remains free. Ad reward receipts and daily gift eligibility are saved locally to prevent duplicate rewards. Local dates use the device clock and are not tamper-proof.

There is no account or sign-in, developer-operated cloud synchronization or recovery, automatic gameplay/save upload, or automatic support attachment upload. We do not receive your local game records through normal gameplay. Operating-system backups are managed separately.

Advertising, payments and identifiers

Versions of Sudokuzy with optional rewarded ads use Google Mobile Ads and Google User Messaging Platform (UMP). Google may receive the device IP address, app interactions such as ad views and taps, diagnostic information and device or app identifiers to deliver and measure ads and prevent fraud. The app removes Android advertising-ID permissions, disables personalized ads and publisher first-party identifiers, and requests child-directed, under-age-of-consent treatment and a general-audience content rating for every player. The age band calculated on the first-run screen stays on this device. Optional ads are unavailable to players aged 13 or younger; all remaining ad requests retain those restrictions. An ad may be prepared after you open an optional reward offer and the privacy check succeeds. It plays only if you choose Watch ad. See Google’s privacy policy at https://policies.google.com/privacy and ad technology information at https://policies.google.com/technologies/ads.

There are no real-money purchases, subscriptions or paid entitlements. All puzzles are included, with completion-based level unlocks and optional early unlocks using earned coins or rewarded ads. Hints use optional rewarded ads or earned virtual coins described above; there is no real-money charge. Ad privacy choices are accessible in Settings. UMP shows a consent form when applicable; child/under-age treatment may mean no form is required. A failed privacy check prevents ad requests. Website and platform providers described separately below have their own information handling.

Offline gameplay and device permissions

Normal gameplay works offline. Android uses internet and network-state permissions for optional ads, plus vibration for optional haptics. No camera, microphone, contacts, precise location or billing feature is used.

The app does not request contacts, precise location, camera, microphone or photo-library access. The Terms and Privacy Policy are bundled and read inside the app without internet access. When you deliberately choose a separately labelled website link or Continue to email, the operating system opens your browser or mail application. No arithmetic or age check is used. That external service handles the resulting request separately; opening it is not a silent upload of your game records.

Reading policies and optional external actions

The Terms of Use, this Privacy Policy and open-source notices can be read inside Sudokuzy without visiting a website. Bundled legal text is a local copy with its own revision date; reading it does not contact a website or load external fonts, scripts, cookies or trackers.

There is no arithmetic gate or tracking/notification permission prompt. The first-run birth date is used to calculate a local age band; the date itself is not saved. No identity document is requested. Optional external website links are labelled as opening a browser. Support forms first show the draft you enter and open your email app only after Continue to email. You decide whether to send it. No support account or automatic sending service is used.

Information you send to support

Emailing us supplies your email address, message and any attachments you choose to include. We use these to respond, investigate an issue and handle privacy requests. Email services process correspondence for delivery and storage; no particular email provider or storage region is promised here.

Please redact unrelated details from screenshots. Do not send passwords, one-time codes, payment details, advertising IDs or unnecessary information about a child. No saves, gameplay logs, screenshots, files, device identifiers, location, credentials or private account data are automatically collected or attached.

Report a Bug and Contact us all address support@matrixbreach.com. A prepared draft includes the product name, chosen category, app version/build, platform name and feature/screen when provided or safely available, followed by your message and optional expected behaviour or reproduction steps. Drafts remain on this device until cleared and are not sent automatically. If no email app opens, you can select/copy the address, subject and complete message. Your chosen email app and account handle sending and attachments.

Visiting this website

Website requests are separate from Sudokuzy’s offline game. Matrixbreach.com uses Hostinger hosting and delivery/security services. Page delivery and access checks can involve your IP address, requested URL, browser details, request time and technical logs. The security service may set a browser-verification cookie.

• Shared typography loads DM Sans and IBM Plex Mono from Google Fonts, sending connection details to Google for those requests.

• The theme control stores your preference in browser local storage as matrixbreach-theme. Other company pages may save calculator, animation or sample-site preferences.

• The corporate contact form uses FormSubmit for email delivery. Sudokuzy’s pages have email links and no submission form.

• No analytics, advertising pixels or third-party embeds are added by this section. This is not a claim that every provider or other company product processes no information.

Read the company website Privacy Policy for broader practices. External destinations operate under their own policies. There is no arithmetic or consent gate on these public pages.

Purposes and applicable legal grounds

Local records operate the game and remember your choices. Support correspondence allows us to answer a request and investigate problems. Hosting/security processing delivers and protects the website.

Where applicable law requires a legal ground, it depends on the activity and jurisdiction. We use correspondence to act on your request and meet relevant legal recordkeeping obligations. We do not treat playing the game or reading this page as blanket consent to unrelated processing. Contact us for information about the grounds relevant to your request.

Retention and local deletion

Local records remain until changed or removed. The save system uses recovery generations to reduce the effects of interrupted writes. Me → Privacy Rights → Delete local progress removes the profile’s active saves, temporary save and preserved recovery copies, then starts a fresh local profile. This includes independent lesson/guide progress, lesson resume/completion, tutorial-audio preferences, saved hints and inactive legacy resource/refill history. That history is not an active free-hint allowance.

That action does not erase separately managed operating-system backups, emails already sent to us, independently held provider information or unrelated files belonging to other profiles or applications. See data and deletion guidance for details.

Support correspondence is kept as long as needed to handle the enquiry, maintain required records or resolve a dispute under our company policy. No fixed deletion period or provider retention schedule is promised. We cannot guarantee restoration after deleting data, reinstalling or changing devices.

Your privacy rights

Depending on applicable law, you may have rights to access, correct or delete personal information, restrict or object to processing, withdraw consent where processing relies on it, or complain to a competent data-protection authority. Ad privacy choices are available in Settings; you can decline optional ads and continue playing offline.

Email support@matrixbreach.com about information sent to MatrixBreach, identifying the relevant correspondence with only the details needed. We may ask for proportionate clarification to protect your information or someone else’s rights. Legal obligations can limit what can be removed. Use device/platform controls for separately managed backups and provider information. Read the deletion guide before removing local progress.

Children and older players

Sudokuzy is intended for children and older players. There is no account, stored birthday or automatic gameplay upload. Players enter a birth date on first run; only the resulting age band is saved locally. Optional ads are unavailable to players aged 13 or younger, and all ad requests use child-directed safeguards. Legal notices stay inside the app. Optional support email and other explicitly chosen external actions are managed by the device and their providers; the app does not verify anyone’s age or identity.

This intended audience is not a store-issued age rating, educational endorsement or compliance certification. Parents and guardians can contact support@matrixbreach.com about information a child may have sent us or request its removal under applicable law. Please avoid sharing unnecessary child information.

Security and platform services

Local saves use versioned files, integrity checks and recovery generations to help detect damage and recover from interrupted writes. Checksums are not encryption and do not guarantee complete security. Protect access to your device and keep software updated.

Operating-system backups are separate from the app’s local saving. They may exist according to device/platform settings; the app does not provide a cloud backup or recovery service. Website and email providers may process information outside your country under their policies and applicable requirements. No particular server region, certification or transfer mechanism is promised.

Changes and contact

Introducing materially different services would require updated notices and applicable safeguards before they begin. We will revise this page and its update date when actual information handling changes, and provide additional notice or choices where required.

Contact support@matrixbreach.com with questions. This public HTML policy can be read without an account, accepting terms or accepting optional cookies.
