Local Browser Tools Privacy Checklist for Developers
Local browser tools are useful because they can avoid unnecessary uploads. They are not magic, though: your own input choices, browser environment, extensions, and shared devices still matter.
Understand what local means
A browser-side tool can process input with JavaScript on your device. That is different from a server-side tool that sends input away for processing. Check the tool description when the distinction matters.
Be careful on shared machines
Local processing does not protect content from browser history, clipboard managers, screenshots, or other people using the same device. Use private devices for sensitive work.
Review browser extensions
Extensions may be able to read page content depending on their permissions. If you work with sensitive samples, use a trusted browser profile with minimal extensions.
Clear temporary content when needed
After working with sensitive samples, clear fields, downloads, and clipboard contents. Save only the cleaned output you actually need.
Do not skip normal security controls
Local tools help reduce uploads, but they do not replace access control, encryption, monitoring, code review, or production data handling policies.
