Cookie Policy

Do we use cookies?

Techsinghge Smart Tools is built to work almost entirely without cookies. The PDF, image, and Excel tools run client-side and don't need a session cookie to function.

What is stored, and where

• localStorage (not a cookie): your theme preference (light/dark), any favorites you save, and your click-to-rate scores for tools are stored in your browser's localStorage — this data never leaves your device and is not a tracking cookie.
• Sign-in session: if you create a free account to use the AI tools, Firebase Authentication keeps you signed in using its own secure session mechanism.
• Analytics: basic, aggregated page-view analytics (Google Analytics) may set cookies to distinguish sessions and understand which tools are popular. These do not include file contents.
• Advertising: if ads are shown on this site, the ad provider (Google AdSense) may set cookies to serve relevant ads and measure performance, in line with their own policies.

Managing cookies

You can clear cookies and localStorage at any time from your browser's settings. Doing so will sign you out of any account and reset your saved favorites, theme, and ratings, but won't affect any files on your device — nothing you've processed with a tool is stored by us in the first place.

Changes to this policy

We may update this policy as the site's features change. Continued use of the site after an update means you accept the revised policy.
