Privacy Policy
This Privacy Policy explains how the Videorist – Video Art Maker app (the "App"), developed by Tran Minh Luan ("I", "me", "the Developer"), handles information when you use the App on iOS or Android. By using the App you agree to the practices described here.
- Your photos and videos are processed on your device. They are never uploaded to me or to any server.
- The App shows ads from Google AdMob. With your permission, AdMob may use your device's advertising identifier to show personalized ads. This is considered "tracking".
- On iOS you are asked for permission through Apple's App Tracking Transparency prompt. You can say no, and you can change your choice at any time.
- I do not sell your personal information, and the App has no user accounts.
1. Information the App processes
Photos and videos you choose
When you pick a photo or video, the App applies artistic styles to it using machine-learning models that run entirely on your device. Your media is not sent to me, to Google, or to any AI service. Finished videos are saved to your photo library only when you choose to save them. The App asks for access to your photo library only for this purpose.
Advertising data (Google AdMob)
If you use the free version, Google AdMob may collect:
- your device's advertising identifier (IDFA on iOS, only if you allow tracking; Advertising ID on Android),
- your IP address and the approximate location derived from it,
- device information (model, operating system, language, screen size),
- information about the ads you see and tap.
Google uses this data to deliver, measure and, if you have allowed it, personalize ads. On iOS, if you do not allow tracking, the advertising identifier is not shared and you will see non-personalized ads. Premium users see no ads.
Analytics and app services (Google Firebase, iOS)
The iOS version uses these Google Firebase services:
- Google Analytics for Firebase: how the App is used (for example, screens opened and styles downloaded), plus device information, an app instance identifier and approximate location. I use this in aggregate to improve the App.
- Firebase Authentication (anonymous): creates a random anonymous ID so the App can download the style catalog. It is not linked to your name, email or phone number.
- Cloud Firestore and Cloud Storage: used only to download the list of styles and the style models. None of your content is uploaded.
- Remote Config: lets me adjust App settings (for example, how often ads appear) without releasing an update.
Consent choices (Google User Messaging Platform)
In regions that require it (such as the European Economic Area, the UK and Switzerland), the App uses Google's User Messaging Platform to ask for your consent to ads and data use, and stores your choice on your device.
Purchases
Premium purchases are handled entirely by the Apple App Store or Google Play. I never receive your payment details. I only receive confirmation of whether your purchase is active.
Information stored on your device
The App keeps your settings and a daily free-usage counter on your device. To prevent the daily limit from resetting on reinstall, this counter (only a date and a number) is also kept in the iOS Keychain or in Google Block Store on Android, which can remain after the App is deleted. It contains no personal information.
2. Tracking and your choices
iOS: App Tracking Transparency
On first launch, iOS shows Apple's system prompt asking whether the App may track you. If you tap Ask App Not to Track, your advertising identifier is not shared with advertisers. You can change your choice at any time in Settings → Privacy & Security → Tracking.
Android: Advertising ID
You can reset or delete your Advertising ID, or opt out of ad personalization, in Settings → Privacy → Ads (or Settings → Google → Ads, depending on your device).
Consent in the EEA, UK and Switzerland
On iOS, you can review or withdraw your consent at any time from Settings → Privacy Options inside the App. On Android, you can reset your choice by clearing the App's data, or contact me to withdraw consent.
Premium
Purchasing Premium removes all ads, so no advertising data is collected by AdMob.
3. Third-party services
These providers process data on the App's behalf under their own privacy policies:
| Service | Platform | Purpose |
|---|---|---|
| Google AdMob | iOS, Android | Advertising |
| Google User Messaging Platform | iOS, Android | Consent management |
| Google Analytics for Firebase | iOS | Usage analytics |
| Firebase Auth, Firestore, Storage, Remote Config | iOS | Style catalog, downloads and app configuration |
| Apple App Store / Google Play Billing | iOS / Android | Purchases |
| Google Block Store | Android | Keeping the daily free-usage counter |
Google's general privacy policy: policies.google.com/privacy. How Google uses data from apps that use its services: policies.google.com/technologies/partner-sites.
4. How information is used and shared
Information is used to provide and improve the App, show ads that keep the App free, measure ad performance, and understand how features are used. I do not sell personal information. Information is shared only with the service providers listed above, or when required by law.
5. Legal bases (EEA, UK and Switzerland)
Where the GDPR or UK GDPR applies, personalized advertising and related data use rely on your consent, which you can withdraw at any time. Delivering the App's features and basic, non-personalized ads rely on legitimate interests in providing and funding a free App.
6. Data retention
I do not store your photos, videos or personal information on my own servers. Data collected by Google services is kept according to Google's retention policies and my Firebase retention settings. Information stored on your device is removed when you delete the App, except the daily free-usage counter described above.
7. Your rights
Depending on where you live (for example, under the GDPR or California's CCPA/CPRA), you may have the right to access, correct or delete your personal information, to object to or restrict its processing, and to withdraw consent. Because the App has no accounts, most data is held by Google and linked only to random identifiers. You can stop further collection by changing the settings in section 2 or by uninstalling the App. For any request, contact me at the email below and I will respond within 30 days.
8. Children
The App is not directed to children under 13 (or the equivalent minimum age in your country). I do not knowingly collect personal information from children. If you believe a child has provided personal information, please contact me and I will take steps to delete it.
9. Security
I use reasonable measures, including encrypted connections to Google services, to protect information. No method of transmission or storage is completely secure, so absolute security cannot be guaranteed.
10. International transfers
Google may process data in the United States and other countries, using safeguards such as Standard Contractual Clauses where required.
11. Changes to this policy
I may update this Privacy Policy from time to time. Changes will be posted on this page with a new effective date.
