<h4>💾 Nothing is stored</h4>
<p>Your images are processed entirely in server memory (RAM). They are never written to disk,
never saved to any database, and are discarded the moment your result is sent back.
There is no way for us to retrieve an image after your request completes.</p>
<h4>🗒 Nothing is logged</h4>
<p>Server access logs are disabled. We do not record filenames, image contents,
IP-address logs, or the results generated for you. Error handling logs only the type of failure,
never your data.</p>
<h4>🍪 No tracking</h4>
<p>This page sets no cookies, runs no analytics, and loads nothing from third-party servers —
every byte comes from this app itself. Your access code is kept only in your browser's session
storage and vanishes when you close the tab.</p>
<h4>📍 Metadata is stripped</h4>
<p>Rendered images are re-encoded from raw pixels, which removes all embedded metadata
(EXIF, GPS location, camera serial numbers) from anything you download.</p>
<h4>🔒 What leaves your device</h4>
<p>Only the image files you explicitly upload, over an encrypted HTTPS connection.
The predicted LUT and rendered image are returned in the same response and belong to you.</p>
<h4>🖥 Hosting</h4>
<p>The service runs on Hugging Face infrastructure; transport is encrypted end-to-end.
No third party is granted access to request contents by this application.</p>
