<h2>Privacy &amp; Security</h2><h3>Can Tresor read my messages?</h3><p><strong>No.</strong> Your messages are encrypted in your browser before they leave your device and are processed inside sealed hardware enclaves that nobody can inspect — not Tresor's team, not the cloud provider. Tresor's database stores only encrypted data. → <a href="https://tresorai.productlane.com/docs/privacy-and-security/how-tresor-protects-your-privacy" target="_blank" rel="noopener noreferrer" class="cursor-pointer box-border border-b hover:border-b-[2px] transition-all duration-75 " style="text-decoration: none; border-color: var(--portal-accent-color);">How Tresor protects your privacy</a></p><h3>Is my data used to train AI models?</h3><p><strong>Never.</strong> Your conversations are not used for training AI models, improving services, or any other purpose beyond responding to you in the current session. This is enforced by the zero-access architecture, not just a policy.</p><h3>What does "zero-access" mean?</h3><p>Zero-access means Tresor is designed so that it <em>cannot</em> access your data, even if it wanted to. Your messages are encrypted end-to-end and processed inside sealed enclaves. It's a technical guarantee, not a promise. → <a href="https://tresorai.productlane.com/docs/privacy-and-security/what-tresor-can-and-cannot-see" target="_blank" rel="noopener noreferrer" class="cursor-pointer box-border border-b hover:border-b-[2px] transition-all duration-75 " style="text-decoration: none; border-color: var(--portal-accent-color);">What Tresor can and cannot see</a></p><h3>Is Tresor GDPR compliant?</h3><p>Tresor is EU-native and designed with European data protection principles. The zero-access architecture goes beyond typical GDPR compliance — if Tresor can't access your data, the privacy risk is fundamentally lower. For specific compliance requirements, <a href="https://trytresor.com/contact-sales" target="_blank" rel="noopener noreferrer" class="cursor-pointer box-border border-b hover:border-b-[2px] transition-all duration-75 " style="text-decoration: none; border-color: var(--portal-accent-color);">contact sales</a>.</p><h3>How do I verify that my conversation is private?</h3><p>Every AI response has a small shield icon underneath it. Click it to see a cryptographic verification receipt that proves the message was processed inside a verified, sealed enclave. → <a href="https://tresorai.productlane.com/docs/privacy-and-security/verifying-your-privacy" target="_blank" rel="noopener noreferrer" class="cursor-pointer box-border border-b hover:border-b-[2px] transition-all duration-75 " style="text-decoration: none; border-color: var(--portal-accent-color);">Verifying your conversation's privacy</a></p><h3>What happens if Tresor is hacked?</h3><p>An attacker accessing Tresor's database would find only encrypted data — unreadable without your personal encryption keys, which are derived from your password and never stored by Tresor. Your account credentials (email/password) are hashed, and 2FA adds another layer. This is a fundamental advantage of zero-access architecture. → <a href="https://tresorai.productlane.com/docs/privacy-and-security/how-tresor-protects-your-privacy" target="_blank" rel="noopener noreferrer" class="cursor-pointer box-border border-b hover:border-b-[2px] transition-all duration-75 " style="text-decoration: none; border-color: var(--portal-accent-color);">How Tresor protects your privacy</a></p><hr><h2>Getting Started</h2><h3>How do I sign up?</h3><p>Go to <a href="https://chat.trytresor.com/auth/signup" target="_blank" rel="noopener noreferrer" class="cursor-pointer box-border border-b hover:border-b-[2px] transition-all duration-75 " style="text-decoration: none; border-color: var(--portal-accent-color);">chat.trytresor.com/auth/signup</a>, enter your name, email, and password, and verify your email with a 6-digit code. → <a href="https://tresorai.productlane.com/docs/getting-started/creating-your-account" target="_blank" rel="noopener noreferrer" class="cursor-pointer box-border border-b hover:border-b-[2px] transition-all duration-75 " style="text-decoration: none; border-color: var(--portal-accent-color);">Creating your account</a></p><h3>Is there a free plan?</h3><p><strong>Yes!</strong> The Free plan includes 20 messages per day, access to all AI models, and full zero-access privacy.
