What we store
Without an account: nothing on our servers. Your watchlist, slider settings and peer sets live in your browser's local storage and never leave it.
With an account: your e-mail address, the time you signed up and last signed in, your subscription tier, and the work you choose to sync (watchlist, saved assumptions, peer sets, saved screens, preferences). Sign-in links and session identifiers are stored only as one-way hashes.
What we do not do
We do not sell or share your data, we do not run advertising networks or third-party trackers, and we do not profile you. Server logs record requests for debugging and are kept for a short period.
We send sign-in links when you ask for them and, if you turn alerts on, the alerts you set. Nothing else unless you opt in.
Deleting your data
Delete your account from the account page. Everything tied to it is removed at once. Clearing your browser's site data removes the local copy.
Where it lives
On a server in the United States. Requests pass through a content delivery network for caching and protection.
