What is stored

If you create an account: your email address, chosen timezone, alert preferences, watch zones and subscription tier. If you enable push notifications: the browser-issued push endpoint and its keys. If you subscribe to the brief by email: your email address and confirmation state. If you leave feedback: the verdict, optional comment and, when signed in, your user ID.

What is not stored

Tremor does not store precise device location. Watch zones are coordinates you enter yourself. There is no advertising, no third-party ad or social tracking pixels, and no sale of personal data.

Processors

Supabase (database, authentication), Vercel (hosting), Resend (email delivery) and Stripe (payments) act as processors. Language-model providers receive only aggregated numeric summaries used to phrase published prose; they never receive personal data.

Row-level security

Personal rows are protected in the database itself: every table carries row-level security policies so a user can only read and write their own records. Public signals, clusters, predictions and briefs are readable by anyone by design.

Your controls

You can unsubscribe from email from any brief footer, revoke push from your browser or settings, and delete your account from settings, which removes your profile, zones, rules, deliveries and push subscriptions.

Retention

Raw provider payloads are kept for 30 days for reproducibility. Signals, predictions and outcomes are kept indefinitely because the public ledger depends on them; they contain no personal data.
