Privacy model (client-side tools)
How Tools by RS Roshi handles data: browser-first processing, what we do not upload, and how that claim maps to product behavior.
Published 2026-07-14 · Updated 2026-07-23
Most tools on this site are designed so your payloads, tokens, and files never need to leave the device for core operations.
Client-side by default
- JSON, encoding, JWT decode, UUID, and hash tools run in the browser
- We do not POST file bodies or JWT contents to an API for those tools
- Input size limits protect the tab from freezing on huge pastes
What this is not
Client-side processing is not a substitute for device security. Anyone with access to your screen or clipboard can still see pasted secrets. Prefer local files and clear the workspace when finished.
Full policy
Read the site privacy page for cookies, analytics, and any endpoints that may exist outside the tool workspaces (for example contact or newsletter forms).

Frequently asked questions
Do tools upload my files?
Default tools process input in your browser. File reads stay on-device subject to size limits. See the privacy policy for logging and any future server features.
