                     <p><strong>SeedPass</strong> is a secure password generator and manager built on Bitcoin's BIP-85 standard. It uses deterministic key derivation to generate passwords that are never stored but can be easily regenerated when needed.</p>
-                    <p>By integrating with the <strong>Nostr network</strong>, SeedPass ensures that your passwords are safe and accessible across devices.</p>
+                    <p>By integrating with the <strong>Nostr network</strong>, SeedPass compresses your encrypted vault and publishes it in 50&#8201;KB chunks. Each chunk is sent as a parameterised replaceable event, with deltas tracking changes between snapshots and automatic rotation when deltas grow large.</p>

                     <p>SeedPass allows you to manage multiple seed profiles (fingerprints). You can switch between different seeds to compartmentalize your passwords.</p>
                     <h3 class="subsection-title">Nostr Relay Integration</h3>
-                    <p>By integrating with the Nostr network, SeedPass securely backs up your encrypted password index to Nostr relays, allowing you to retrieve your index on multiple devices without compromising security.</p>
+                    <p>SeedPass publishes your encrypted vault to Nostr in 50&#8201;KB chunks using parameterised replaceable events. A manifest describes each snapshot while deltas record updates. When too many deltas accumulate, a new snapshot is rotated in automatically.</p>
