Your privacy is our utmost priority. Text Prefix is designed from the ground up as a pure offline utility that requires zero personal data.
App Name: Text Prefix
Owner / Company: DV Siam
Effective Date: September 11, 2026
1. Introduction & Overview
This Privacy Policy describes the policies and practices of DV Siam ("we", "our", or "us") regarding the collection, use, and disclosure of information when you use the Text Prefix mobile application (the "App") available on the Google Play Store.
Text Prefix is a lightweight text processing utility designed to quickly append prefixes and suffixes to multiple lines of text simultaneously. We believe that simple utility apps should respect user privacy completely. Therefore, our core design philosophy is: no accounts, no tracking, no internet connection required.
2. Zero Data Collection
Complete Privacy Guarantee
Text Prefix DOES NOT collect, store, transmit, process, or share any personally identifiable information (PII) or user data of any kind.
Specifically:
No Personal Information: We do not collect names, email addresses, phone numbers, contacts, device IDs, or IP addresses.
No User Account: You do not need to register, log in, or provide any credentials to use the App.
No Analytics or Tracking: The App contains no tracking cookies, behavioral analytics, Firebase analytics, or telemetry libraries.
No Advertisements: The App contains no third-party ad networks (such as AdMob, Unity Ads, etc.) and does not track your advertising identifier.
3. On-Device Text Processing
All text processing operations—including prefix addition, suffix addition, character counting, and line formatting—are performed 100% locally on your device's memory (RAM).
Your input text is never saved to persistent storage without your knowledge and is never sent across the internet. When you close or restart the application, the text residing in memory is immediately cleared by your operating system.
4. Permissions & Clipboard Use
The App requires minimal device permissions to operate:
Internet Access: Text Prefix requires zero internet permissions (android.permission.INTERNET is not requested). The App operates in complete isolation from the internet.
Clipboard Access: The App accesses the clipboard only upon explicit user action—specifically when you tap the "Paste" button to input text or the "Copy Result" button to copy your formatted output. The App never accesses your clipboard in the background.
5. Children's Privacy (COPPA & GDPR-K)
Because Text Prefix does not collect any personal data whatsoever, it is fully safe for users of all ages, including children under 13 (in the United States) and children under 16 (in the European Union).
We do not knowingly solicit or collect information from children. If you have any questions regarding child safety in our apps, please reach out to us at the contact address provided below.
6. Security & Changes to Policy
Since no user data travels across network channels or resides on external servers, the risk of data breaches, leaks, or unauthorized access is eliminated.
We may occasionally update our Privacy Policy to reflect app updates or regulatory compliance. Any revisions will be posted directly to this web page with a refreshed "Effective Date" at the top. We encourage you to review this page periodically.
