Privacy
What this site stores about you, why, and how to remove it.
Without an account
You can read the site without an account. We set no cookie for you and run no advertising, no analytics and no tracking scripts. The pages load script libraries (htmx and the chart library) from jsDelivr, a content delivery network at cdn.jsdelivr.net, which therefore receives your address like any web server; these scripts are not used for tracking. The web server keeps ordinary access logs (address, time, page) for a short time to keep the service running.
With an account
- Your e-mail address, to send the sign-in link and the alerts you turn on.
- Your watchlist and your alert settings.
- Your price alerts: the symbol, the price you chose, and two prices from Yahoo Finance, the one when you created the alert and the one when it fired.
- A session cookie named
sid, set when you sign in and removed when you sign out, and otherwise kept for up to 30 days. It only keeps you signed in. The server stores a fingerprint of it, not the cookie itself. - Sign-in links: a fingerprint of each link, together with the address it was sent to. These records are deleted about a day later, when a link is next requested.
- Rate limiting: to limit abuse of the sign-in form, the server keeps the client address of sign-in requests in memory for up to an hour. It is never written to disk.
There is no password. We do not sell or share this data. It is sent to our mail provider only as far as needed to deliver a message to you.
Market pages
Quotes, charts and company figures on the market pages come from Yahoo Finance through this server. The server keeps them in memory only, for at most about 80 minutes (company financials; quotes and charts far less), and never writes them to disk. Your browser does not contact Yahoo: the request goes from this server to Yahoo, and Yahoo sees the server, not you.
Removing your data
Use "Delete the account" on the account page: your address, watchlist and settings are removed at once. Every alert mail has an unsubscribe link.
