Privacy first

Tool data and site requests stay separate

Tool input and results are processed in temporary state for the current page. The TabPebble application does not send them to a server, write them to a database, or create processing history. Pages and code still load through ordinary network requests. Your browser may restore a tab, while downloads and clipboard copies remain on the device until you remove or replace them.

  • No tool-task upload
  • No account
  • No processing history

FAQ

Frequently asked questions

Why can some cells gain a leading apostrophe?

Spreadsheet programs can interpret values beginning with characters such as =, +, -, or @ as formulas. The default prefix reduces that risk, but no CSV safeguard is universal across every spreadsheet app. Turn it off when exact machine-readable values matter more.

Is this tool free?

Yes. Core tools are free to use and do not require an account.

Does tool input go to a server?

No. The TabPebble application performs the tool task in your browser and does not put input into site requests; ordinary page and code requests still reach the hosting service.
