Hashing, similarity embeddings, clustering, and bad-photo detection all run locally on your iPhone or iPad using Apple's Vision and PhotoKit frameworks. There is no DupeOut server because there is no DupeOut server. Nothing to upload, nothing to leak, nothing to subpoena.</p>https://hechen.github.io/apps/dupeout/support.htmlMon, 01 Jan 0001 00:00:00 +0000https://hechen.github.io/apps/dupeout/support.html<div class="gradient-bg"> <div class="max-w-2xl mx-auto px-6 sm:px-8 pt-12 sm:pt-20 pb-6"> <a href="../dupeout/" class="inline-flex items-center gap-2 text-sm text-slate-500 dark:text-slate-400 hover:text-accent dark:hover:text-accent-dark transition-colors mb-8"> <svg class="w-4 h-4" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2"><path d="M19 12H5M12 19l-7-7 7-7"/></svg> DupeOut </a> <h1 class="text-4xl sm:text-5xl font-bold tracking-tight">Support</h1> <p class="mt-3 text-sm text-slate-500 dark:text-slate-400">Built and maintained by one person.
