Most files never leave your device
Most TooloSea tools do their work entirely inside your browser. When you compress an image or format a JSON file here, the data never travels to a server — there is nothing for us to store, log or leak, because we never receive it in the first place.
A few tools genuinely need a server: looking up a domain record, for example, has to happen from somewhere with a network connection. Those tools say so plainly on the page, tell you exactly what is sent, and delete anything temporary within the hour.
