Your data is strictly yours. Zero uploads.
DeDupe Kit was intentionally designed with zero server-side storage, zero telemetry, and zero tracking.
1. Local In-Browser Processing
Every text operation—including line splitting, regex filtering, case normalization, deduplication, and sorting—occurs exclusively inside your web browser's temporary execution thread.
When you paste content into the input box or drag a file into the studio, the data is held only in your browser's local RAM. As soon as you close or refresh the tab, the memory is instantly freed and cleared by your browser's garbage collector.
2. Zero Server Transmission
DeDupe Kit does not make POST, PUT, or API calls to any backend server with your content.
You can verify this yourself by opening your browser's Developer Tools (press F12), navigating to the Network tab, pasting a list, and watching the network log. You will observe exactly zero requests being dispatched.
3. No Advertising, Analytics or Cookies
We do not use advertising networks (such as Google AdSense), behavioral trackers, session recording software (such as Hotjar or FullStory), or third-party marketing cookies. There are no tracking beacons, pixels, or profiling scripts embedded anywhere on dedupekit.pages.dev.
4. Enterprise & GDPR / CCPA Safe
Because DeDupe Kit never collects, stores, or processes personal data on any server infrastructure, using DeDupe Kit to clean customer lists, email addresses, database records, or internal identifiers does not constitute a data transfer under GDPR, CCPA, or HIPAA.
Your proprietary files and confidential records never leave your company's network or local machine.
5. Offline Capability
DeDupe Kit is fully functional in offline environments. Once loaded, you can disconnect your device from the internet or enable Airplane Mode to guarantee complete isolation while cleaning sensitive lists.
