Privacy notice
Last updated 27 October 2026. What personal data we handle, why, and the choices you have.
Who we are
Quanexas (quanexas.com) is operated by Sohail Shaik. This notice explains what personal data we handle and why.
What we collect
Learning progress. The learning levels, study topics, roadmap, Academy and practice pages save your checklists, lesson and topic progress, quiz scores, solved challenges, edits to code exercises and "find your level" result in your browser’s local storage. That information is not sent to Quanexas and does not sync between devices.
Running code in study topics. When you press Run in a study topic, your browser downloads the Python runtime (Pyodide) and any packages it needs from the jsDelivr content delivery network, which receives a normal web request, including your IP address. Your code and its results stay on your device; nothing you type into a code box is sent to Quanexas or to jsDelivr.
Toolbox. The browser tools process sequences, files and values entirely on your device. Nothing you paste or open in the Toolbox is uploaded to Quanexas or anyone else.
Enquiries. The contact form sends the name, email address, topic and message you provide to Formspree for delivery to our inbox.
Member accounts. Registration, sign-in and password resets use Supabase Auth, which processes your email address and authentication data, including authenticator-app two-step verification (TOTP). The member database stores your account email, account creation time, member-feature status and assigned role. Your Supabase sign-in session is stored in your browser. Quanexas never receives or stores your password.
Optional profile details. Members may choose to add a display name, professional title or study area, company or school affiliation, biography, GitHub or portfolio URL, LinkedIn URL, country and phone number. You can edit these at any time from the member dashboard.
Please do not submit health information or other sensitive data through any of these services.
How we use it
Enquiry details are used to respond to your message. Account details are used to provide sign-in, account recovery and account security. Quanexas does not sell personal data, use it for advertising, or add you to a mailing list without asking.
Who can see it
Your optional profile details are visible to you and to verified Quanexas administrators. Only the Quanexas owner can grant or revoke member roles; administrators can review profiles and enable or suspend member features.
A member with the Colleague role may separately opt in to show selected professional fields — display name, title, affiliation, country, biography and profile links — on the public team page. Email addresses and phone numbers are never published.
Cookies and analytics
The site does not set tracking cookies and does not use analytics. If privacy-conscious analytics are added in future, this notice will be updated before they are switched on.
Third parties
Hosting is provided by Vercel. Enquiry delivery is provided by Formspree, and account authentication by Supabase; the Supabase client library is served by esm.sh, and the Python runtime for study topics by jsDelivr. Their privacy notices and terms also apply. The site’s typeface is hosted on quanexas.com itself, so no font provider receives your visit.
Your rights
Where UK data-protection law applies, you can ask to access, correct or delete your personal data, and exercise other applicable rights. Contact us and we will respond within one month.
