Your files
Files you use in the tools are processed only inside your browser on your device. File content and file names are never sent anywhere, including to this site's servers, and we cannot see them. When you close the page, any file data left in the browser is gone too.
Information we collect
Visit statistics
We use Cloudflare Web Analytics to see how much each page is used. It does not use cookies and does not identify or track individual visitors. It collects:
- The address of the page you visited and how you arrived there
- Your browser and operating system type, and the country you visited from
- How long the page took to load
These statistics run only outside the tool area. The tool area is an isolated space, so the statistics cannot read your file content or file names.
Access logs
This site is served through Cloudflare's servers. Cloudflare processes access logs such as IP addresses to deliver the site and to block attacks. We do not use these logs to identify visitors.
Emails you send us
If you email us, we receive your email address and the content of your message. We use them only to reply, keep them for one year after we finish replying, and then delete them. If you ask us to delete them sooner, we will do so right away.
Ads and cookies
This site is funded by Google AdSense ads. When you open a page, Google's ad program is loaded, and Google and its partners may use cookies to show ads based on your visits to this and other sites.
- You can turn off personalized ads in Google Ad Settings.
- See how Google uses information from sites that use its services.
- You can delete or block stored cookies in your browser settings.
- In regions where consent is required, such as Europe, you can choose whether to allow cookies in Google's consent message.
Ads only appear outside the tool area. The tool area is an isolated space, so ads cannot read your file content or file names.
If an ad blocker is on, a message asks you to turn it off. We only check on your device whether the ads could be loaded, and the result is never sent anywhere.
What we store in your browser
The only things this site stores itself are your light or dark theme choice and the language you picked. These values are never sent to a server.
Other companies that process information
We never sell or hand over information. We use the following services to run the site.
- Cloudflare (USA): serving the site, visit statistics, forwarding contact emails
- Google (USA): storing contact emails (Gmail), ads (AdSense)
Their servers are located abroad, so this information may be processed outside Korea.
Your requests
You can ask to see or delete the emails you sent us. Contact us at the address below and we will take care of it. Visit statistics cannot be linked to any person, so we cannot find or delete them for you.
Changes
If the way we handle information changes, for example by adding an analytics tool or ads, we will update this page and its effective date before the change.
