PRIVACY POLICY
Effective Date: Mar 26, 2026 (Last Updated: March 26, 2026)
DST SOLUTION JOINT STOCK COMPANY operates the ThemeHub: Themes and Widgets application, which is provided at no cost and is ad-supported. This privacy policy is intended to inform users regarding the collection, use, and disclosure of personal information when using our Service.
By using the Service, you agree to the collection and use of information in accordance with this policy.
We may collect and use personal information to provide and improve our Service. The types of personal data we collect include:
Device or Other IDs: We may collect Device IDs (such as UUID, Advertising ID, or other unique device identifiers) for the purposes outlined in this policy. We do not collect IMEI or MAC addresses.
Approximate Location: Derived from your device's IP address.
Log Data: If the app encounters an error, we may collect log data such as your device's IP address, device name, operating system version, app configuration, and usage statistics.
In-App Activity: Information about your interactions with the app, such as app launches, feature usage, and session duration (collected via Firebase Analytics).
Cookies: We do not explicitly use cookies, but third-party services like Apple App Store Services , AdMob, and Firebase Analytics may use cookies or similar technologies to collect information for their services.
Precise Location: The app can access your device’s precise location (GPS) when you grant the CAMERA + LOCATION permission together and use features like “add GPS watermark” or “geo-tag photos”. This data is processed only on-device and NEVER sent to our servers or any third party.
Crash logs with installed apps list: Firebase Crashlytics automatically collects a list of all apps installed on your device when a crash occurs. This helps us fix bugs faster. Google receives this list. You can disable it any time in Settings → Privacy → Analytics & diagnostics → turn off “Share analytics with developers”.
The personal information we collect is used for the following purposes:
To provide and maintain the Service (e.g., core camera functionality).
To improve, personalize, and enhance the Service (e.g., feature recommendations based on usage).
To monitor the performance and error reporting of the app.
For targeted advertising and analytics purposes (e.g., serving relevant ads via AdMob).
We will not use or share your information except as described in this Privacy Policy. You can opt out of personalized advertising by adjusting your device settings (iOS: Settings > Privacy & Security > Tracking, then turn off “Allow Apps to Request to Track”)
Our app uses third-party services that may collect information used to identify you. These include:
Apple App Store Services
AdMob
Firebase Analytics
These third parties may collect and use data in accordance with their own privacy policies. You can find links to their privacy policies below:

Advertising and Opt-Out Options
This app uses Google AdMob to display ads. AdMob (provided by Google) may collect data such as your device advertising ID, IP address, and usage information to serve personalized ads.
Google does not sell your personal information. However, the use of your data for personalized advertising may be considered a "sale" or "sharing" of personal information under certain US state privacy laws (e.g., California, Colorado, Virginia, etc.).
How to opt out:
1. Opt out of personalized ads: Go to your device settings > Google > Ads > Opt out of Ads Personalization (on Android) or Settings > Privacy & Security > Apple Advertising > Personalized Ads (turn off on iOS).

Yes, we share the following personal information with third parties:
• Device advertising ID
• IP address (approximate location)
• App usage data (via Firebase Analytics)
• Crash logs and performance data
These are shared with:
• Google AdMob (for showing ads)

You can stop all sharing for advertising at any time using the opt-out methods listed above.
Right to Know Whether Your Personal Information Is Sold
You have the right to know if we sell your personal information.
We do NOT sell your personal information in the traditional sense.
However, sharing your Device Advertising ID and usage data with Google AdMob for personalized ads may be considered a “sale” or “sharing” under certain US state privacy laws (California CCPA, Colorado CPA, Virginia VCDPA, etc.).
Therefore, YES — this specific sharing for personalized ads is legally treated as a “sale” in some states.
You can stop this “sale” instantly using any of these methods:
1. Device settings → Google → Ads → Opt out of Ads Personalization
2. Device settings → Privacy → Apple Advertising → turn off Personalized Ads (iOS)
3. Online: https://myadcenter.google.com (click “Do Not Sell or Share My Personal Information”)
4. Online: https://adssettings.google.com
After opting out, you will only see non-personalized ads and no further “sale” occurs
