[+] End-2-End Encrypted, and Searchable - Granular Flexible Encryption: Encrypt an entire note or only its most sensitive content. - Chain-Wide Search: Unencrypted notes can index and search the entire Note Chain. - Stored neither on the server nor on your device: only briefly in memory when needed for decryption. - Flexible Face ID & Fingerprint Protection — for encrypted content, app access, or not at all.
