Privacy Policy — Skin Master

Effective date: September 18, 2026

Skin Master ("the App") is developed and published by Thanh Mich LTD ("we," "us," "our"). This Privacy Policy explains what information the App and the third-party services it uses can collect, why, and what choices you have. It describes the App as it actually behaves — no more, no less.

If you have questions, contact us at thanhmichltd@gmail.com.

1. No account, no sign-in

Skin Master does not have a login, sign-up, or user account of any kind. You can open the App and use every feature immediately. We do not know your name, email address, or any other identity information, because we never ask for it.

2. What the App itself does with your device

• Browsing the skin/character/weapon/pet/bundle/vehicle/map catalog and item details: the content is bundled with the App or fetched as generic catalog data; opening it does not send anything that identifies you.
• Diamond calculator: the number you type is used only to compute a result on your device. It is never stored or transmitted anywhere.
• Spin Wheel and Lucky Box: these mini-games run entirely on your device; the outcome is decided locally.
• Downloading an image: when you tap Download on an item, the App saves that image file to your device's own photo library, in a folder named Pictures/SkinMaster, using Android's standard MediaStore APIs. The file stays on your device — the App does not upload it, and we have no server that receives it. On Android 9 and earlier, this requires the classic "Write to external storage" permission; on Android 10 and newer it uses the modern scoped-storage APIs and does not need that permission at all.
• Language setting: your chosen display language is saved locally on your device so the App remembers it next time.

3. Advertising, attribution, and analytics services

Skin Master is free and is built on a shared technical template that includes advertising and measurement SDKs. This version of the App is not yet showing live ad placements on any screen, but the SDKs below are compiled into the App and initialize when it starts. We disclose them here regardless of whether ads are currently visible, because that is what is actually running on your device:

Service	What it's for	What it can receive
Google Mobile Ads (Google AdMob)	Serving and mediating ads	Advertising ID, device/app information, ad interaction events
AppLovin	Ad mediation partner used by the above	Advertising ID, device/app information
Meta Audience Network (Facebook)	Ad mediation, ad-event measurement	Advertising ID, app-event data, device/app information
Adjust	Install attribution / marketing measurement	Advertising ID, device/app information, install/referrer data
TikTok Business SDK	Install attribution / marketing measurement	Advertising ID, device/app information
Google User Messaging Platform (UMP)	Shows the consent/ad-choice prompt required in the EEA/UK and other regions before any ad personalization happens	Your consent choice, general region
Firebase Analytics	Understanding how the App is used, in aggregate	App interaction events, device/app information
Firebase Crashlytics	Finding and fixing crashes	Crash logs, stack traces, device/app information
Firebase Remote Config	Delivering configuration/feature values to the App	Firebase installation identifier

None of these services receive your name, email address, phone number, or the images you download — the App simply does not have that information to share. Each of these providers processes data under its own privacy policy:

• Google (AdMob, Firebase, UMP): https://policies.google.com/privacy
• AppLovin: https://www.applovin.com/privacy/
• Meta (Audience Network): https://www.facebook.com/privacy/policy/
• Adjust: https://www.adjust.com/terms/privacy-policy/
• TikTok Business: https://www.tiktok.com/legal/page/eea/privacy-policy/en

4. Purchases

This version of Skin Master does not sell anything. There is no store screen, no subscription, and no "remove ads" button anywhere in the App. (The manifest carries the standard Play Billing permission because it ships with the same shared ads/monetization module used across our apps, but no purchasable product is configured or offered to users in this build.) If that changes in a future update, this Privacy Policy and the App's Terms of Use will be updated before any purchase becomes available.

5. Permissions this App requests, and why

Permission	Why
Internet / network state / Wi-Fi state	Required by the advertising, attribution, and analytics services listed in §3 to operate
Advertising ID (AD_ID, plus the Android 13+ Privacy Sandbox equivalents)	Read by the same services, to serve and measure ads
Play Billing	Bundled infrastructure only — see §4; unused in this version
Notifications (POST_NOTIFICATIONS)	Declared by our shared app template; this version does not send you any notifications
Write external storage (Android 9 and earlier only)	Lets the App save a downloaded image into your device's Pictures folder, as described in §2

The App does not request camera, microphone, contacts, calendar, SMS, call log, or location access.

6. Your choices

• Limit ad tracking: you can reset or opt out of your Android Advertising ID at any time in your device's system settings (Settings → Privacy/Google → Ads).
• Ad consent: where required by law (for example the EEA/UK), you'll see a consent prompt (powered by Google's User Messaging Platform) the first time you open the App, and you can change your choice later through the App's settings if that option is available in the version you have installed.
• Delete data: because Skin Master has no account and no server-side storage of your data, there is no "delete my account" step to take. To remove everything the App has stored on your device, uninstall it. Any image you downloaded stays in your device's photo library after uninstall, exactly like a photo you took yourself — delete it from your gallery app if you no longer want it.
• Children: Skin Master is a general-audience app and is not directed at, or knowingly marketed to, children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us at thanhmichltd@gmail.com and we will address it.

7. Data retention

We do not operate a backend that stores your personal data, so we have nothing of yours to retain or delete on our own servers. Data collected by the third-party services in §3 is retained according to each provider's own policy, linked above.

8. Security

We rely on the security practices of the Android platform and of the third-party providers listed above. No method of transmission or storage is 100% secure, but we do not operate any server that stores personal data about you in the first place, which limits our own exposure.

9. Changes to this policy

We may update this Privacy Policy as the App changes (for example, when ad placements go live or an IAP is introduced). We will update the effective date above when we do. Continued use of the App after an update means you accept the revised policy.
