Privacy Policy

Last updated: 2026-06-24

At wai-tools, your privacy comes first. This policy explains how we handle data when you use our free online tools — unit converters, calculators, and image and PDF utilities.

Your files and data

Our image and PDF tools run entirely client-side — all processing happens directly in your browser. We do not store, upload, or transmit your files to any server. When you close the page, those files are immediately cleared from your browser's memory.

Cookies and analytics

We use Google Analytics to understand aggregate website usage, such as which tools are popular and how many people visit. This data is anonymized and aggregated, and helps us improve our tools.

We may display ads through Google AdSense, which can use cookies to serve ads relevant to your interests. Third-party vendors, including Google, may use cookies to serve ads based on your visits to this and other websites.

Your choices

You can disable or delete cookies through your browser settings, and manage Google's personalized ad preferences via Google Ads Settings. Disabling cookies does not affect your ability to use our core tools.

Changes to this policy

We may update this policy from time to time to reflect changes to our service or legal requirements. The latest revision date is always shown at the top of this page.
