Privacy
Most DevToolkit tools process your data locally in the browser and don't intentionally store your input.
How your data is handled
The formatters, converters, encoders and generators on DevToolkit run entirely as JavaScript in your browser. Text you paste into a tool — JSON, YAML, CSV, a JWT, a regex, a URL — is processed on your device and is not sent to a DevToolkit server as part of the tool's normal operation.
We don't intentionally log, store or transmit the content you type or paste into any tool. Standard web infrastructure (such as hosting and CDN providers) may still see connection metadata like IP address and request timing as part of normal web traffic, which is outside our direct control.
What we can't guarantee
We avoid making absolute claims we can't technically back up. Browser extensions, network intermediaries, or misconfigured environments could in theory observe data on your own device outside of our control. DevToolkit itself does not add tracking scripts or send tool input to third parties.
A note on sensitive tools
Tools like the JWT Decoder work entirely client-side, but you should still avoid pasting secrets, passwords, API keys or production credentials into any online tool — including this one — as a general security practice.
Cookies and analytics
DevToolkit does not use tracking scripts. A single local storage entry remembers your light/dark theme preference; it never leaves your browser.
