Privacy Policy

1. Who we are & scope

MxT APP ("MxT APP", "we", "us" or "our") is an independent studio that develops and publishes mobile applications on the Apple App Store and Google Play under the developer name MxT APP. MxT APP is the data controller responsible for your personal information. You can reach us at maixuantruongcvdev@gmail.com.

This Privacy Policy explains what information our mobile applications (each an "App", together the "Apps") and this website collect, how we collect it, how we use and share it, how long we keep it, and the choices you have. It applies to every App we publish unless an App shows you a separate privacy policy, in which case that policy applies to that App.

Not every App uses every type of data or service listed below. The exact data each App handles is shown in its App Privacy section on the App Store and its Data safety section on Google Play, and those disclosures are consistent with this policy.

2. Information we collect

2.1 Information you provide

• Content you create in an App — such as notes, lists, settings or photos you choose to add. Unless an App offers cloud sync or an account, this content is stored only on your device and never reaches us.
• Account information — if an App offers sign-in (for example with Apple, Google or email), we receive your name and email address, or an anonymized relay address if you use Apple's "Hide My Email".
• Support messages — your email address and anything you include when you contact us.

2.2 Information collected automatically

• Device and app information — device model, operating system version, language, app version and general region.
• Usage data — which screens and features are used, session length and in-app events, collected in aggregated or pseudonymous form.
• Diagnostics — crash reports and performance data that help us fix bugs.
• Identifiers — app-instance IDs and, only where you allow it, the device advertising identifier (IDFA on iOS, Advertising ID on Android).
• Approximate location — derived from your IP address and used for ad relevance, fraud prevention and regional settings. We do not collect precise (GPS) location unless an App clearly needs it for a feature you use and you grant permission.

2.3 Device permissions

Some Apps may ask for access to the camera, photo library, microphone, notifications, contacts or location. We request each permission only when the related feature needs it, explain why before asking, use it only for that feature, and never upload the related data unless the feature requires it and says so. You can revoke any permission at any time in your device settings.

3. How we use information

• To provide, operate and maintain the Apps and their features;
• To process purchases and restore subscriptions;
• To understand how the Apps are used and improve them;
• To detect, diagnose and fix crashes and technical problems;
• To show advertising in free versions of our Apps (see section 5);
• To send notifications you have opted in to;
• To respond to your questions and support requests;
• To prevent fraud and abuse, and to comply with legal obligations.

We use your information only for the purposes listed above. If we want to use it for a new purpose, we will update this policy and, where required, ask for your consent first.

Where the EU/UK General Data Protection Regulation (GDPR) or similar laws apply, we rely on these legal bases: performance of a contract (providing the App), your consent (e.g. personalized ads, optional permissions), our legitimate interests (analytics, security, improving the Apps) and compliance with legal obligations.

We do not sell your personal information, and we do not use it to make decisions that have legal or similarly significant effects on you.

4. Third-party services

Our Apps may use the following service providers. Each processes data on our behalf and under its own privacy policy. We only work with providers that are bound by contract or by their published terms to protect personal data with the same or equal level of protection described in this policy.

5. Advertising & tracking

Free versions of some Apps display ads served by Google AdMob. Ad partners may use device identifiers and approximate location to show ads and measure their performance.

• iOS: we ask for permission through Apple's App Tracking Transparency prompt before tracking you across apps and websites owned by other companies or using your IDFA. If you decline, you will only see non-personalized ads. You can change this at any time in Settings › Privacy & Security › Tracking.
• Android: you can reset or delete your Advertising ID, or opt out of personalized ads, in Settings › Google › Ads (or Settings › Privacy › Ads). We use the Advertising ID only for advertising and analytics, and never link it to personal information or persistent device identifiers without your explicit consent.
• EEA, UK and Switzerland: we show a consent message (via Google's certified consent management platform) before personalized ads are shown, and you can change your choice later from the App's settings.

Purchasing an ad-free option, where offered, removes ads from that App.

6. Purchases

In-app purchases and subscriptions are processed entirely by Apple or Google. We never receive or store your payment card details. We receive only the information needed to confirm your purchase, such as a transaction ID, product, price, date and country.

7. Sign-in, health & sensitive data

• Sign in with Apple / Google: we receive only the name and email address you choose to share. We use them solely to create and secure your account.
• Health and fitness data: if an App connects to Apple HealthKit or Android Health Connect, that data is used only to provide the App's health features. It is never used for advertising or marketing, never sold, never shared with third parties for those purposes, and never stored in iCloud or on our servers unless a feature clearly requires it and you agree.
• Photos, contacts and microphone: accessed only when you use a feature that needs them and processed on your device whenever possible.

8. Sharing & disclosure

We share information only:

• With the service providers listed in section 4, who process it on our behalf;
• When required by law, court order or a valid request from a public authority;
• To protect the rights, safety and property of our users, the public or MxT APP;
• As part of a merger, acquisition or sale of assets, in which case this policy will continue to protect your information;
• With your explicit consent.

9. Retention & security

We keep personal information only as long as needed for the purposes described in this policy:

We protect your information with industry-standard measures, including encryption in transit (HTTPS/TLS), encryption at rest by our cloud providers, access controls limited to people who need it, and secure, reputable infrastructure. No method of transmission or storage is 100% secure, but we work hard to protect your information and will notify you and the relevant authorities of a data breach where the law requires.

10. Your rights & choices

Depending on where you live, you may have the right to:

• Access the personal information we hold about you and receive a copy of it;
• Correct inaccurate information;
• Delete your information;
• Object to or restrict certain processing;
• Withdraw consent at any time — for example by changing tracking or ad settings, turning off permissions in your device settings, or contacting us;
• Data portability;
• Lodge a complaint with your local data protection authority.

California residents (CCPA/CPRA) have the right to know, delete and correct personal information, and to opt out of the "sale" or "sharing" of personal information. We do not sell personal information; you can limit ad-related sharing using the settings in section 5. We will not discriminate against you for exercising your rights.

Users in other regions with data protection laws (such as Brazil's LGPD, Canada's PIPEDA, or similar laws in Asia-Pacific) have the rights those laws provide. To exercise any right, email us at maixuantruongcvdev@gmail.com. We may need to verify your identity, and we will respond within 30 days.

11. Account & data deletion

You can delete your account and associated data at any time, free of charge:

• In the App: where an App has an account, open Settings › Account › Delete account. Deletion starts immediately.
• On the web: follow the steps on our account deletion page, or email maixuantruongcvdev@gmail.com with the subject "Delete my data", the App name, and the email or user ID linked to your account.

We delete your account data within 30 days of verifying the request. Some information may be kept longer where required by law (for example, purchase records), and anonymized analytics that can no longer identify you may be retained. Deleting the App from your device removes all locally stored data. Deleting your account does not cancel a subscription — cancel it separately through the App Store or Google Play.

12. Children's privacy

Our Apps are not directed at children under 13 (or the equivalent minimum age in your country), and we do not knowingly collect personal information from them, in line with the U.S. Children's Online Privacy Protection Act (COPPA) and similar laws. If you believe a child has provided us personal information, please contact us and we will delete it. If any App is designed for children, it will follow Apple's Kids Category rules and Google Play's Families Policy, and will not use personalized advertising or third-party analytics that track children.

13. International transfers

Our service providers may store and process data in countries other than the one you live in, including the United States. Where required, we rely on appropriate safeguards such as Standard Contractual Clauses so that your information remains protected wherever it is processed.

14. This website

This website does not use cookies, analytics or advertising trackers. It loads fonts from Google Fonts, which receives your IP address to deliver them. If you email us, we use your message only to reply.

15. Changes to this policy

We may update this Privacy Policy from time to time. We will post the new version on this page with a new "Last updated" date and, for material changes, notify you in the App or by other reasonable means before they take effect. Continued use of the Apps after an update means you accept the revised policy.
