ETF Research Project ("we", "us") respects your privacy. This policy explains what personal data we collect through this site — in particular, the 0050 price alert service — and how we use and protect it.
We don't use analytics or tracking tools, and we don't collect data via cookies.
We do not send newsletters, general updates, or marketing information. The email address you provide when subscribing to a price alert is used solely to send you the specific alert(s) you configured — nothing else.
Data submitted via the contact form is used only to respond to your inquiry or feedback.
Price alert subscription data is stored in a Cloudflare D1 database, accessed and transmitted over encrypted connections. To analyze how the site is used, we also record statistics without your email address (such as sign-up time, chosen conditions, language and country) in a Google Sheet for internal use only. We do not sell, rent, or share your personal data with third parties for marketing purposes.
To operate this site, we rely on a small number of service providers who process limited data on our behalf: Cloudflare (hosting and database), Resend (sending confirmation and alert emails), and Formspree (handling the contact form). Each processes data only as needed to provide their service, under their own privacy policies.
When you open the foreign net selling page, or tick "Show foreign net selling" on the adjustable parameters page, your browser fetches public foreign investor figures directly from FinMind (finmindtrade.com). As with connecting to any website, FinMind receives basic connection details such as your IP address, which it handles under its own privacy policy. We don't share your email address or alert settings with FinMind.
We may revise this policy from time to time. Since we don't send email beyond the alerts you've configured, any changes will simply be reflected on this page rather than emailed to you.
If you have questions about this policy, or want to access, correct, or delete your data, please reach out via the form on the "About Us & Contact" page.
