Privacy
This site keeps as little as it can. Here is exactly what happens to your data.
Last updated: 11 November 2026
Who is responsible
Tony Tang, Paris, France, runs learn-rust-ts.tonytang.dev. For anything about your data, write to tony@tonytang.dev.
The website
The site is hosted on Vercel, which processes technical data such as IP addresses to deliver pages and protect them from abuse. There is no advertising and there are no cookies.
Visits are counted with Vercel Web Analytics: the page you view, the site that sent you, your country, and your browser, system and device type. It sets no cookies and doesn't follow you across other sites.
The Learn Effect trailer is served from media.tonytang.dev on Cloudflare, which receives your IP address when the poster or the video loads.
The waitlist
- If you join, your email address and, if you answer it, what you would use Rust for are stored by Brevo, an email service based in France that keeps this data in the EU.
- Brevo sends you a confirmation email first. Until you click its link, you are not on the list.
- The list is used only for this course: at most two emails, one when it is in production and one when it is out, with the waitlist discount. Every email has an unsubscribe link.
- The list is deleted once the waitlist discount has ended.
Transfers outside the EU
Vercel and Cloudflare may process data outside the European Union, including in the United States, under their own terms and safeguards.
Legal basis and your rights
Joining the waitlist relies on your consent, which you withdraw by unsubscribing. Hosting and visit counts rely on legitimate interest: running the site securely and knowing whether it is useful. You can ask for access to your data, correction, deletion or restriction, and you can object, by writing to the address above. You can also complain to the CNIL, the French data protection authority.
