Launched OBSCURA OS, a zero account, 100% client side workspace and privacy toolkit

Hey IH, I built OBSCURA OS. Everything runs client side in the browser, so there is no server storing your data and no account system to breach or subpoena. The Workspace Suite covers docs, sheets, slides, notes, file storage, forms and calendar, and is free. The Sovereign Suite adds 8 privacy tools (PDF redaction, biometric protection, leak detection, steganography, secure data splitting and more) for a one time $9, no subscription. Backups are a portable JSON file you control. Would love feedback from this crowd, especially on whether the free plus $9 unlock split feels right or should work differently.
