Privacy Policy
The short version: what you put into the tools never leaves your device.
Tool inputs
Every tool on Tenuko runs entirely in your browser. Text you paste, numbers you enter and files you open are processed locally on your device and are never transmitted to our servers or anyone else's. The one exception is the currency converter, which fetches current exchange rates from a public API - the amount you're converting is not sent, only the request for rates.
Analytics
We may collect basic, anonymous usage statistics (which pages are visited, roughly where from) to understand which tools are useful. This never includes anything you enter into a tool.
Advertising
The site may show adverts to keep the tools free. Ad networks may use cookies subject to their own policies; where required, you will be asked for consent before any such cookies are set.
Local storage
Some tools (like the notepad) save data to your browser's local storage so you don't lose work between visits. That data stays on your device and can be cleared at any time from your browser settings.
