Privacy notice

How we handle selected files and aggregate usage counts.

1. Selected files

File contents and filenames are processed by JavaScript in your browser. There is no file upload server, file-storage database, or file-content analysis service. Results are downloaded to your device. Closing the page or clearing it releases the processing data held by the page; files you downloaded remain on your device.

2. Hosting and connection information

The site is hosted on Cloudflare. Network information such as IP address, request time, URL, and browser details may be handled by the hosting provider for service operation and security. This is separate from your selected files. See Cloudflare privacy information.

3. Accounts, cookies, and analytics

No account is required to use the tools. Tool inputs are not saved in local storage. Advertising tracking scripts are currently disabled.

To improve the tools, we count tool page views, successful processing operations, and download clicks. Cloudflare Workers and D1 store the date in Korean time, tool identifier, event type, user-file or sample-file category, interface language, and daily count. Filenames, contents, input values, IP addresses, visitor identifiers, and cookies are not stored in the statistics database. Connection IPs are used transiently for rate limiting, but are not saved in the statistics database. We do not create individual browsing histories. Network information may still be processed for hosting as described above.

4. Contact messages

If you email us, your address and message are used to respond. Do not send passwords, personal identifiers, real customer lists, or sensitive original files. Describe a reproducible issue with private information removed.

5. Contact and updates

A public contact email has not been added yet.

We update this notice when features or external services change. Effective date: 2026-10-11.
