Privacy policy
What we collect. Your email address, an optional first name, your trial and membership status, sign-in times, and the study notes and checklist entries you choose to save. If you pay, we keep your Stripe customer and subscription IDs and the time you accepted the terms. Card details go straight to Stripe and never reach our servers.
How we use it. To run your membership: sign-in links, billing, support and your private workspace. Your notes are never shown to other members. We do not sell or rent your data, and we use no advertising trackers.
Cookies and browser storage.
- mddt_s keeps you signed in. It lasts up to one year, or until you log out.
- mddt_billing protects the join and billing forms from forged requests. It lasts two hours.
- The learning path saves the steps you tick in your browser's local storage. That list stays on your device and is not sent to us.
Services we use. Each one receives only what it needs to do its job.
- Google Fonts serves the site's fonts, so Google sees your IP address and browser details.
- jsDelivr serves the chart code on pages with charts and sees the same kind of details.
- Stripe takes payments and runs the page where you update your card or cancel.
- Apple takes payments in the iPhone app. We receive the subscription's dates and an ID from Apple, not your name or card. You can subscribe in the app without giving us an email.
- Our email sender (Google Workspace or Resend) delivers sign-in links and membership emails.
- WhatsApp is used if you book a 1:1 session. WhatsApp's own privacy policy covers those messages.
- Market data providers supply prices, charts and option data. We ask them for ticker symbols, never for anything about you.
Server logs. Our web server keeps standard logs (IP address, page requested, browser type) for security and to fix problems.
Your choices. Email support@markedchart.com to get a copy of your data or to delete it, or delete your account yourself in the iPhone app under Account. Deleting your account ends your membership.
