Privacy & Security

How your files are processed

Every A.C.U.T.E. Labs tool processes files entirely within your browser using standard web APIs and open-source libraries (pdf-lib, JSZip). No file content is transmitted to any server.

You can verify this yourself: open DevTools → Network tab while using any tool and observe that no file bytes are sent to any external service.

What we collect

License key validation

When you enter a Pro license key, the key is sent to a Cloudflare Pages Function (an edge function on our domain) which validates it against the Lemon Squeezy API. The key itself is stored in your browser's localStorage. No file content is involved in this step.

Cookies and local storage

We use localStorage to remember your license key and your daily usage count for the free tier. No tracking cookies are set.

Third parties

Your rights (UK GDPR)

As we hold no personal data beyond what you choose to submit via the contact form, your rights to access, rectify or erase data are straightforward to exercise. Contact us and we will respond within 30 days.
