Pro features & cloud backup

Cosmos Pro keeps your local-first brain safe and portable: cloud backup over TLS, automatic daily backups, and a one-click restore when you move to a new Mac. It is live for alpha invitees today, with public sale planned for Q3 2026.

Pricing

• $12/mo or $108/yr (two months free on the annual plan).
• Live for alpha invitees today; public sale Q3 2026.
• 30-day free Pro trial, no card required.

What's included

• Cloud backup over TLS — turn it on in Settings → Files & Backup → Cloud backup. Data is plaintext at rest today; client-side encryption ships Q3 2026.
• Daily auto-backup — runs every 24 hours while the app is open, so your brain is always recoverable.
• One-click restore on a new Mac — an idempotent merge that never deletes existing data. Safe to run repeatedly.
• Priority support, early feature access, and roadmap input.

Coming Q3 2026 (included for current Pro)

• Real-time sync between Macs — a CRDT-based delta engine that keeps multiple Macs in sync continuously, included for current Pro subscribers when it lands.

Is there a free trial?

Yes — a 30-day free Pro trial with no card required. Start it from Settings → About → Sign up / Log in.

Is my backup encrypted?

Backups travel over TLS today. At rest, data is currently plaintext; client-side encryption ships Q3 2026.

Will restore overwrite my existing data?

No. Restore performs an idempotent merge — it never deletes existing data, and running it more than once is safe.
