Privacy Policy
Last updated: [date]
This policy explains what Vesper (“we,” operated by [Company Legal Name]) collects, why, and your choices. It covers the Vesper app and this site.
What we collect
To sign you in we collect your email address (used for a magic link — Vesper has no passwords). When you use the app we store the cities you save and your preferences (units, voice), and the trips and questions you send to the Ask Vesper planner. We also collect basic, non-identifying usage information to keep the service running.
How we use it
To provide the service: to sign you in, sync your cities across your devices, and answer your planner questions. We use your email only to send the sign-in link and important service notices — not marketing, unless you opt in.
Weather & AI processing
Weather comes from Open-Meteo; only the coordinates or place you ask about are sent to fetch it. Planner questions are processed by Anthropic (Claude) to generate a grounded answer. Answers are grounded in real weather data; beyond 16 days Vesper shows typical conditions, clearly labeled — never presented as a forecast.
Storage & security
Your data is stored with Supabase (Postgres), protected by owner-only row-level security so only you can read your rows. API keys for our providers are held server-side and never shipped to your browser.
Sharing
We do not sell your data. We share it only with the processors that run Vesper — [Supabase] (database/auth), [Anthropic] (planner), [Vercel] (hosting), and [Resend] (email) — solely to operate the service.
Your choices
You can use Vesper signed out (your cities live only in your browser). Signed in, you can request access to or deletion of your data by contacting us. Deleting your account removes your saved cities, preferences, and trips.
Children
Vesper is not directed to children under 13, and we do not knowingly collect their data.
Changes
We'll post any changes here and update the date above; material changes will be noted in the app.
