What you remember is often a single sentence within a document, not the file name.
Chatda reads the documents on your phone not only by name but also by the text, so it can find them even if you ask using a sentence.
■ This app does not have internet permissions
- Search terms, file names, and document content do not go anywhere. The app cannot establish a connection at the operating system level.
- There are no accounts or logins, and there are no ads or tracking. The thin line at the very top of the screen is a link introducing other programs, apps, and games from the developer (Project Team For You), and the phone's browser opens only when you tap it — the app does not directly connect or send anything.
- You can verify directly that there is no internet access in the "Permissions" list in the app information.
■ Searches down to the main text
- Hangul (including HWP, HWPX, and government-issued documents), PDF, Word, Excel, PowerPoint, ODF, Text
- Documents inside compressed zip files
- You can ask in sentences: "How much is the penalty fee?"
- Twelve language screens: Korean, English, Japanese, Chinese, German, French, Spanish, Portuguese, Indonesian, Russian, Arabic, Hindi

- 1 million file names This is "Chatda" for Windows, which indexes in under a second and searches not only HWP, PDF, and Office text files, but also scanned documents (OCR) and documents within ZIP files.
- As it is a searcher identical to the one on your phone, it performs the same searches for initial consonants, keyboard typos, and sentence lengths. All searches are conducted exclusively within your PC.

- To find documents on your PC from your phone, please use the "Chatda Remote" app in conjunction (using the same Wi-Fi and bypassing the internet).
■ The Reason for Using Access to All Files
- To find any document located anywhere on your phone, it must read all files on the device. It only reads files; it does not modify, delete, or send them outside the device.

I search for documents on my phone by content, not by name. I cannot go anywhere because I do not have internet permission.
