swc.guru is an unofficial site about The Smarter Web Company, run by one person. It collects as little as it can, never sells your data, and has no adverts or third-party tracking.
swc.guru is run by Dex, an individual SWC shareholder in the UK, who is the data controller for the personal data described here. To get in touch about your data, use the chat on any page, the feedback form, or message @swcguru on X.
We count visits with our own analytics, not Google's. For each page view we store the page, where you came from (just the website, e.g. x.com), any campaign tags in the link, your country (from our network provider), device type, browser, operating system, screen width and how long the page was open.
To tell visits apart without cookies, we make an anonymous visitor code from a scrambled version of your IP address and browser that changes every day, and a random session code kept in your browser tab until you close it. We never store your IP address. Analytics is kept for about 13 months, then deleted.
If you sign up for email updates we store your email address, which updates you chose and when you confirmed. Every email has a one-tap unsubscribe. If you unsubscribe we keep a note of that so we don't email you again; ask and we'll delete it completely. Emails are sent through Resend, and open and click tracking is off.
If you create an account we store your name, email address and a securely scrambled password (we can't read it), plus what you add: trades, portfolios, notes, goals, price alerts and your settings. If you turn on two-factor we store its secret encrypted and your backup codes scrambled. We also note when you were last signed in.
Your trades are private to you and never shown publicly or shared. If you ask for help, or something looks wrong, the site's admin can open your My SWC read-only to look into it. Nothing can be changed, sent or downloaded, each look lasts 30 minutes at most, and every one is logged with the reason.
You can download everything you've added, or delete your account and everything in it, from Settings at any time. Deleting your account doesn't cancel email updates, which are separate: use the unsubscribe link in any email.
The app works without an account. If you turn on notifications, we store a random ID the app makes for your phone, Apple's push token for it, which alerts you chose and any price alerts you set. If you start the lock screen price, we store that Live Activity's push token until the day ends. Notifications are sent through Apple's push service.
If you sign in to My SWC in the app, we store a sign-in token for that phone (only a scrambled version) and when it was last used. Face ID happens on your phone and nothing about it reaches us. Signing out, or deleting your account, removes the sign-in. Turning notifications off in the app or deleting the app stops all notifications.
If you sign up to test the app before release (swc.guru/beta), we store your name, email, which iPhone you have, and your X handle and note if you add them. They're only used to invite you through Apple's TestFlight and to email you about the beta, and you can ask us to delete them at any time. To invite you, your name and email are given to Apple, which then emails you the invite.
If you use the chat or the feedback form we store what you write and any name, email or X handle you give, plus the page you were on. If you leave an email we may reply to it. Your X handle is only mentioned publicly if you ticked the box to be credited. Ask and we'll delete your messages.
You can ask to see the data we hold about you, correct it, delete it, limit how we use it, object to us using it, or get a copy to take elsewhere. Just ask using the contact options above; we'll reply within a month. If you're unhappy with how we've handled your data you can complain to the Information Commissioner's Office (ico.org.uk).
