Privacy policy
Your logbook is yours. We built Vesper so high-responsibility work can stay private.
What we store
Account email, notes, composed entries, accomplishments, threads, settings, and optional integration data you connect (for example Whoop, Apple Health via Auto Export, or Cadence).
What we don’t do
We do not sell your personal data. We do not use your journal content to train AI models.
Processors
We use trusted providers only to run Vesper: Supabase (database and auth), Cloudflare (hosting), Resend (email), Anthropic and Voyage (AI composition and search embeddings when you use those features). They process data on our instructions and do not receive rights to use your journal for their own model training.
Local storage
The app may store session tokens and offline notes on your device (browser storage and IndexedDB) so you can stay signed in and capture notes without a connection.
Your controls
Export your data anytime from Settings. You can delete your account permanently from Settings → Your data.
