Privacy Policy

Rangoo

Last updated: March 15, 2026

Viral Apps Studio ("we", "our", or "us") built the Rangoo app ("the App") as a free application. This page informs you of our policies regarding the collection, use, and disclosure of information when you use our App.

Information We Do Not Collect

Rangoo does not require account creation, login, or any form of registration. We do not collect, store, or transmit any of the following:

• Personal information (name, email, phone number)
• Location data
• Contacts or address book data

Analytics and Crash Reporting

The App uses Firebase Analytics and Firebase Crashlytics to help us understand how the App is used and to identify and fix issues. These services may collect:

• Usage data: Anonymous events such as which features are used (e.g., category selected, conversion started/completed), navigation actions, and app launch events
• Crash reports: Technical information about app crashes, including device model, OS version, and stack traces, to help us diagnose and fix bugs
• Device information: Device type, operating system version, and app version

This data is collected in aggregate and does not personally identify you.

Advertising Identifier (IDFA)

The App may request access to your device's advertising identifier (IDFA) through Apple's App Tracking Transparency framework. This identifier is used to deliver personalized ads and improve your experience. You can choose to allow or deny this request, and you can change your preference at any time in your device's Settings under Privacy & Security > Tracking. The App functions fully regardless of your tracking preference.

On-Device Processing

The majority of file conversions — including all image, video, and audio formats — are performed entirely on your device using on-device conversion engines. Your files for these conversions are never uploaded to any server.

Document Conversions via Third-Party Service

For document format conversions (DOC, DOCX, PDF, HTML, ODT, RTF, TXT), the App uses a third-party service called CloudConvert to process the conversion. When you convert a document:

• Your file is temporarily uploaded to CloudConvert's servers for processing
• The converted file is downloaded back to your device
• CloudConvert deletes uploaded files from their servers after processing

CloudConvert's privacy policy is available at cloudconvert.com/privacy. We do not share any personal information with CloudConvert — only the file content necessary for conversion.

Data Stored on Your Device

The App stores the following data locally on your device only:

• Conversion history: Records of files you have converted, including file names, formats, thumbnails, and dates (up to 500 records)
• Converted files: Output files from conversions, stored in the App's local storage
• App preferences: Your settings such as preferred language and theme

This data never leaves your device and is not accessible to us. You can delete this data at any time through the App or by deleting the App.

Device Permissions

The App may request access to the following device features:

• Photo Library (read & write): Used to import images, videos, and other media files for conversion, and to save converted files back to your photo library. We do not access any files beyond what you explicitly select.
• Camera: Used to capture photos and videos directly for conversion.
• Microphone: Used to record audio directly for conversion.
• Files app: Used to import and export documents and other files for conversion through the iOS file picker.
• Notifications: Used to send optional daily reminders. You can enable or disable notifications at any time in your device's Settings.

These permissions are requested only when needed and can be revoked at any time in your device's Settings.

Third-Party Services

The App uses the following third-party services:

• CloudConvert: Used for document format conversions as described above. Only file content is transmitted; no personal data is shared.
• Firebase Analytics: Used to collect anonymous usage data to help us improve the App. See the "Analytics and Crash Reporting" section above.
• Firebase Crashlytics: Used to collect crash reports and diagnostic data to help us fix bugs and improve stability.
• Firebase Remote Config: Used to deliver app configuration updates (such as feature flags and supported format lists).

Children's Privacy

The App does not knowingly collect any information from children under the age of 13. The App does not require any personal information to function.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. Continued use of the App after changes constitutes acceptance of the updated policy.
