Add True End-to-End Encryption (Zero-Knowledge) so Stoic Stays 100% Private#1196

Stoic is where people write the most sensitive parts of their lives, therapy notes, relationship conflict, fears, trauma, finances, identity, medical details. That only works long-term if privacy is mathematically guaranteed, not just “we won’t look.” Please add true end-to-end encryption (zero-knowledge): a key derived from my passcode stays on my device; Stoic can’t read entries, even on your servers.

What it looks like: “Privacy Lock” in Settings → set a passcode/biometric, optionally a recovery key. All journals, tags, attachments, and mood data are encrypted locally before sync. New device? I unlock with my passcode/recovery key. Add Optional: “Local-only mode” for users who don’t want cloud.

Why it makes Stoic better: instant trust, safer journaling, stronger retention, and a clear differentiator vs competitors, because even in a breach, there’s nothing readable to steal.
