MATINTA — Privacy Policy

This Privacy Policy explains how the mobile game MATINTA (package net.jjunior.matinta) handles information. MATINTA is developed and published by J Junior (the "Developer", "we", "us"), the independent studio behind jjunior.net.

1. Who we are

MATINTA is created by J Junior, an independent mobile game developer (jjunior.net). For any privacy question, you can reach us at jjunior.development@gmail.com.

2. What MATINTA does (and does not do)

MATINTA is a single-player story game. To keep it honest and lean:

• it is free, with optional rewarded ads only (you choose to watch a video for a reward), and the ads never block the story;
• it has no in-app purchases and collects no payment data;
• signing in is optional: you can play the whole game without an account;
• it does not access your location, camera, microphone or contacts.

3. The services we use

MATINTA relies on two Google platforms, each described in plain terms below.

Google AdMob (advertising)

MATINTA uses Google AdMob (the Google Mobile Ads SDK) to show rewarded video ads that you opt into. To serve and measure those ads, Google may use device identifiers (including the advertising ID), your IP address, and ad interaction data. Where required (for example in the EU, the EEA and the UK), MATINTA shows Google's UMP / GDPR consent form on first launch so you can choose whether ads are personalized.

Google Firebase (accounts, cloud save, stats, diagnostics)

MATINTA uses several Google Firebase services:

• Firebase Authentication — optional Google sign-in (anonymous sign-in is also used) so your progress can be linked to you;
• Cloud Firestore — cloud save of your progress, plus aggregated, anonymous statistics of the choices players make, and a streak leaderboard;
• Remote Config — feature flags that let us tune the game remotely (no personal data);
• Analytics & Crashlytics — app usage events and crash reports, so we can understand how the game is used and fix problems.

4. Data we process

What is processed depends on whether you sign in:

• If you sign in with Google: a Google account identifier (and the email associated with it) and your game progress and in-game choices, saved to the cloud via Firebase.
• If you do not sign in: your progress stays local or is tied to an anonymous identifier, and is not linked to a personal account.
• For ads and measurement (everyone): device and advertising identifiers, IP address, and ad and app interaction data, processed by Google through AdMob and Firebase Analytics.
• For stability: crash logs and basic device information through Crashlytics.

MATINTA does not collect payment data and does not ask for sensitive personal information.

5. Data stored on your device

Some information is saved locally on your device, including your chosen language, settings, and, when you are not signed in, your progress, streak and collected Tales. You can remove local data at any time by clearing the app's data or uninstalling the app.

6. Accounts & cloud data

Signing in is entirely optional and exists so you can keep your progress across devices. You can:

• play without an account and keep everything on your device;
• sign out at any time;
• request deletion of your cloud data by contacting us at jjunior.development@gmail.com, and we will remove the data associated with your account.

7. Ads & your choices

On first launch, where required, MATINTA shows Google's UMP / GDPR consent form so you can choose whether to allow personalized ads. You stay in control:

• manage or revoke consent through the in-app consent options where the form is available;
• reset your advertising ID or opt out of ad personalization in your Android settings (Settings → Privacy / Google → Ads).

8. Children

MATINTA is not directed to children under 13 and is intended for a general, mature-leaning audience given its themes. We do not knowingly collect personal data from children. If you believe a child has provided data, please contact us and we will work with Google to address it.

9. Your rights

Depending on where you live (including under the GDPR in the EU/EEA/UK and the LGPD in Brazil), you may have rights to access, correct, delete or export your data, and to object to or restrict certain processing. You can exercise ad-personalization choices through the controls in Section 7, manage your account data through Section 6, and contact us at jjunior.development@gmail.com for anything else. For the data Google holds as a provider, see the Google Privacy Policy.

10. Retention & international transfers

Local data stays on your device until you clear it or uninstall the app. Cloud data linked to an account is kept until you ask us to delete it or delete your account. Data processed for ads, analytics and stability is retained by Google according to its own policies. Google operates globally, so data may be processed in countries other than your own, under the safeguards described in Google's documentation.

11. Google Play Data Safety

For transparency, this is consistent with our Google Play "Data safety" declaration:

Data type	Processed by	Purpose	Notes
Email address & account ID (only if you sign in)	Firebase Authentication	Account, cloud save	Optional; processed by Google
Game progress & in-game choices	Cloud Firestore	Cloud save, aggregated stats, leaderboard	Collected if signed in

App activity & interactions	Firebase Analytics	Analytics	Processed by Google
Crash logs & diagnostics	Firebase Crashlytics	Stability / diagnostics	Processed by Google

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page and publish the new version here at this same URL. Significant changes may also be noted on the MATINTA page.
