Privacy Policy
What data Thread Academy collects, why, and your rights.
Last updated: November 2, 2026
01What we collect
We collect the minimum data needed to run the service: • Your IP address — used only to enforce the Ask AI daily question limit (5 per day without sign-in). These counters reset every day. • If you sign in with Google: your name and email address, provided by Google, used to identify your account and enforce the higher limit (30 questions per day). • The questions you ask the Ask AI tutor, which are sent to our AI provider to generate answers. • Visit statistics: the page visited, the site you came from, your country, region and city, and your browser, operating system and device type. We collect these through Vercel Web Analytics to see which pages help students. They are used as aggregated statistics, not to identify you.
02What we don't collect
We do not run advertising trackers. We do not sell your data, and we do not share it with third parties except the service providers strictly needed to operate the site (Vercel for hosting and visit statistics, Cloudflare for the Ask AI service, Google for sign-in, and our AI provider for answers).
03Where your data lives
When you sign in, a secure token is kept in your browser's local storage so you stay signed in for 7 days. This token never leaves your device except to authenticate your requests to our tutor service.
04How long we keep data
Anonymous rate-limit counters are deleted daily. Sign-in tokens expire after 7 days. If you want your account data deleted sooner, contact us (see below) and we will remove it.
05Children's privacy
Thread Academy is built for school students. If you are under 13, please use the site with a parent's or teacher's guidance. We do not knowingly collect data from children beyond what is described above, and we never use student data for advertising.
06Your rights
You can ask us at any time what data we hold about you, ask for it to be corrected, or ask for it to be deleted. To make a request, contact us through the website.
07Changes to this policy
If we change this policy, the new version will be posted here with an updated revision date. Significant changes will be highlighted on the site.
