IREUMGYEOL

Privacy & data handling

Your selected file contents and rename tables stay in your browser.

Updated: October 10, 2026. This notice describes this version of Ireumgyeol at rename.charyetimer.com.

Files and filenames

The tool reads the files you select using browser APIs. File contents, names, table entries, and previews are held in the tab’s memory. The app does not upload them to a server or send them to an AI service. ZIP files and rename logs are generated locally. Your original files are not modified.

Storage on your device

The app does not use cookies, local storage, or session storage to retain your selected files, inputs, or language choice. Refreshing or closing the tab clears the app’s working state. Files you download remain in your device’s downloads folder until you delete them. Your browser may cache the website’s public HTML, styles, and scripts.

Website delivery and security

Amazon Web Services hosts and delivers this website. Requests to load it necessarily include connection information such as IP address, requested URL, browser headers, and request time. AWS may process this information to deliver the service and protect it from misuse. This connection information is distinct from the files you select in the renaming tool. Never place sensitive information in a page URL.

Analytics and advertising

This release does not load analytics scripts, advertising scripts, or external fonts. If these change, this notice and any required choices will be updated before those services are introduced.

Contact emails

If you email onceinyourlife16@gmail.com, the address and information you send are processed through the email service to respond to your request. Do not attach confidential files. You can use the same address to ask about or request deletion of information you have sent; requests are handled subject to applicable obligations.

Practical precautions

Use the tool only on files you have permission to handle. Check downloaded filenames and contents before sharing them. Filenames themselves can contain private information, including in a rename log. On a shared device, remove downloads you do not want to leave behind.
