Privacy Policy & Security Architecture Transparency
Updated our Privacy Notice and security disclosures to explicitly detail PBKDF2 password derivation, AES-GCM-256 encryption at rest, Cloudflare Workers AI processing boundaries, and client-side calculation defaults. Corrected legacy phrasing regarding local calculation to precisely delineate local client execution from optional authenticated cloud saving.
