Theme Store: Widget Changer · Bundle ID: com.luantran.themeiconwallpaper · Last updated: October 25, 2026
This Privacy Policy explains how Mun Studio ("we," "us," or "our"), the developer of Theme Store: Widget Changer (the "App"), handles information when you use the App and its widgets on iPhone.
In short: the App has no account and never asks for your name, email address, contacts or location. Your loved themes, diamonds, widget settings and to-do lists stay on your iPhone. What does leave your device is listed below: an anonymous ID and usage data for the theme catalog and analytics, advertising data for free users, and anything you choose to send us.
1. Information the App processes
| Information | Why | Where it goes |
|---|---|---|
| An anonymous user ID created by Firebase Authentication | Lets the App read the theme catalog and download themes. Not linked to your name or any account. | Google Firebase |
| App usage events (for example, screens opened, themes viewed or installed, buttons tapped), with the anonymous user ID, device model, iOS version, app version and approximate region | Understand which themes and features are used, and fix problems | Google Analytics for Firebase |
| Theme requests (which catalog pages, previews and theme files are fetched, and when) | Show the gallery and download themes | Google Firebase (Firestore, Cloud Storage) and Cloudflare R2, which receive your IP address as part of serving files |
| A +1 on a theme's public download count, and a +1 or -1 on its love count when you tap the heart | The download and love numbers shown on each theme. The counts are not linked to you. | Google Firebase (Firestore) |
| Icon requests and issue reports you write in the App, with a random ID for this device, whether Premium is active, the app version, iOS version, language and, when relevant, the theme | Draw the icons you ask for and fix the problems you report | Google Firebase (Firestore) |
| Your invite code, a random ID for this device, and how many friends used your code | Give diamonds to you and the friends you invite | Google Firebase (Firestore) |
| Coupon codes you enter | Check and redeem the coupon | Google Firebase (Firestore) |
| A push notification token, only if you allow notifications | Send notifications about new themes | Google Firebase Cloud Messaging and Apple |
| Advertising data: device and app information, IP address, ad interactions, and the Identifier for Advertisers (IDFA) only if you allow tracking | Show, limit and measure ads, and prevent ad fraud | Google AdMob |
| Purchase receipts | Unlock Premium and add purchased diamonds | Apple. We receive no payment details; receipts are checked with Apple. |
| Requests for tutorial videos, widget fonts and the list of our other apps | Play the install guides, offer fonts for widgets, and show our other apps | Google Cloud Storage, Google Fonts and Cloudflare Pages, which receive your IP address as part of serving them |
| Messages you send through our contact page or by email | Answer your feedback or support request | Our website and email providers |
2. Information kept only on your device
These never leave your iPhone:
- the themes you unlocked and installed, your Loved themes, and your diamond balance;
- your widgets and their settings, including the text, fonts, colors, countdown dates and to-do items you add;
- your app language and other settings, and whether Premium is active;
- small counters that decide when to show a tip, a rating request or another pop-up.
Deleting the App removes this information. A random device ID and your invite status are kept in the iOS Keychain so that an invite cannot be claimed twice; iOS may keep them after the App is deleted.
3. Icons, wallpapers and Photos
Icons. To add a theme's icons, the App builds an iOS configuration profile with home screen shortcuts and hands it to Safari from a small server that runs only on your iPhone. The profile is not sent to us. You can remove it at any time in Settings › General › VPN & Device Management.
Photos. The App asks for permission only to add photos, so it can save a theme's wallpapers to your library. It cannot see or read your existing photos.
4. Advertising and your choices
Free users see ads from Google AdMob, including videos you choose to watch for diamonds. Premium removes ads.
- Tracking (ATT): iOS asks whether the App may track you. If you decline, the IDFA is not shared and ads are not personalized using it. You can change this in Settings › Privacy & Security › Tracking.
- Consent in the EEA, UK and Switzerland: Google's consent form asks for your choices where the law requires it. You can reopen it from Settings › Privacy choices in the App.
- Notifications: you can turn them off in Settings › Notifications › Theme Store.
- Google's use of advertising data is described at How Google uses information from sites or apps that use its services.
5. How we share information
We do not sell your personal information and do not share it for purposes other than those above. Information is processed by these service providers under their own terms: Google (Firebase, AdMob, Cloud Storage and Fonts), Cloudflare (file hosting), and Apple (the App Store, in-app purchases and notifications). We may also disclose information when required by law or to protect the App, our users or our rights.
6. Retention
The anonymous Firebase user ID stays until you delete the App, after which it is no longer used. Download and love counts are kept as totals. Analytics data is kept for the period set in Google Analytics. Icon requests and issue reports are kept while we work on them and then deleted. Service providers keep request logs for the periods set out in their own policies. We keep support messages as long as needed to help you, then delete them.
7. Your rights
Because the App has no account, we hold very little that identifies you. Depending on where you live, you may have the right to access, correct or delete personal information, or to object to its processing. To make a request, contact us using the details below. To reset advertising choices, use the options in section 4.
8. Children
The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us information, contact us and we will delete it.
9. Security and international processing
Connections between the App and its services are encrypted. Our service providers may process information in countries other than yours, using the safeguards applicable law requires. No method of storage or transmission is completely secure.
10. Changes
We may update this policy as the App changes. We will post the new version here and update the date above.
