What we collect

Almost nothing. SmartToolKit Lab does not require sign-up and operates no user accounts. Our tools (JSON Formatter, ROI Calculator, Image Compressor) run entirely in your browser — data you paste or upload never leaves your device and is never sent to our servers.

Cookies

SmartToolKit Lab itself does not set cookies and uses no analytics trackers. We display ads served by our advertising partner Monetag; Monetag and its partners may use cookies or similar technologies to serve and measure ads. See Monetag's Privacy Policy and opt-out page.

Local storage

We use browser local storage only to remember your theme preference (dark/light). It stays on your device.
