Effective: October 19, 2026. Creator Upload Lab is a static website hosted on Cloudflare Pages. The current tools operate in the visitor's browser. The site does not send files, captions, screenshots or calculated values to an application server and does not provide accounts.
Locally processed files
If you choose a subtitle or background image file, its contents are processed with JavaScript on your device. The subtitle checker reads the text into your browser's memory to report issues and generate a download. The image preview uses a temporary local browser object URL. We do not intentionally persist these files remotely.
Hosting and connection data
Cloudflare, as host and network provider, may process connection-related information such as IP address, user agent, network timestamps and security information according to its own practices. We do not claim to control all infrastructure-level logging. Read Cloudflare's privacy policy for provider details.
Cookies, analytics and advertising
This site does not currently embed third-party analytics or advertising scripts and does not intentionally set marketing cookies. Essential security or infrastructure features may be applied by the hosting provider. If advertising or analytics are introduced later, this notice must be updated and any applicable consent or disclosure requirements assessed before launch.
Contact emails
If you send an email to kimkidong1402@gmail.com, we may see the email address and content you voluntarily provide. Use email only for questions or corrections; do not send passwords, tokens, private media or sensitive personal information. You can request deletion of your correspondence by replying to the same address, subject to legal recordkeeping obligations.
Policy changes
When practices change, we will update this page with the new effective date. In the meantime, no personal file content is required to use these free tools.
