Haven is a premium, offline-first journal, diary, and reflective notebook designed specifically for Windows. Built for quiet thought and deep reflection, Haven combines the tactile beauty of artisanal stationery with the speed, privacy, and zero-knowledge cloud synchronization of a modern desktop application. 100% OFFLINE-FIRST & ZERO-KNOWLEDGE PRIVACY Your thoughts, memories, and personal reflections belong only to you. Haven stores all your entries, tags, and media locally on your device in a high-performance SQLite database. No mandatory accounts, no telemetry, and no tracking. ZERO-KNOWLEDGE ENCRYPTED CLOUD SYNC (BYOC) Sync your journal seamlessly across your Windows PCs and laptops with complete peace of mind: • Bring Your Own Cloud: Works with your existing OneDrive, Google Drive, Dropbox, Nextcloud, or local network folder/NAS. • End-to-End Encrypted (E2EE): Encrypted before leaving your machine using OWASP-recommended Argon2id key derivation and military-grade AES-256-GCM. Neither your cloud provider nor anyone else can read your entries. • Zero Cloud Subscriptions: No recurring fees, no cloud account logins required by Haven, and zero vendor lock-in. • Dual-Envelope Emergency Recovery: Generate an offline 32-character recovery key (HVN-SYNC-...) to restore access even if you forget your master passphrase. • Visual Conflict Diff & 1-Click Merge: Never lose an idea—when syncing offline edits across devices, Haven flags divergent changes non-destructively and lets you review diffs side-by-side.
