This Privacy Policy explains what Klass collects, why, and what choices you have. It's written in plain English on purpose. If something is unclear, email us at privacy@klass.app.
1. Who we are
Klass is operated by an independent team building AI-powered learning tools for parents, teachers, and adult learners. The current site is at klass-2gq.pages.dev.
2. Who Klass is for
Klass accounts are for adults 18 and older. The Homework Helper is designed for parents to use on behalf of their children — not for children to use directly.
privacy@klass.app and we will delete it.
3. What we collect
When you create an account, we collect:
- Email address — to sign you in and (if needed) reach you about your account
- Name — to greet you in the product
- Date of birth — to confirm you're 18 or older
- Role — parent, teacher, learner, or admin
- Password hash — we never see your actual password (it's hashed with PBKDF2 and a random salt)
- Account timestamps — when you signed up and when you accepted these terms
When you use the product, we receive:
- The text you submit (homework problems, lesson topics, role-play replies)
- The AI responses generated for you
- Standard web request data (IP address, user agent, timestamps) handled by our hosting provider, Cloudflare
We do not collect: location, payment information, browsing history, or any tracking identifiers across the web.
4. How your inputs are processed by AI
To generate responses, Klass sends your inputs to a third-party AI provider, DeepSeek (operated by Hangzhou DeepSeek AI Co., Ltd., based in China). When you paste a homework problem or send a role-play message, that text is transmitted to DeepSeek's servers, which may be located outside the United States.
If you do not want your inputs sent to DeepSeek, do not use Klass.
Do not paste sensitive personal information (Social Security numbers, financial account details, medical records, or anything else you would not want a third party to see) into Klass.
5. Cookies
We use one cookie: klass_session. It keeps you signed in. It is HttpOnly, Secure, and SameSite=Lax. We do not use advertising or analytics cookies.
6. How we use your information
We use what we collect only to:
- Operate the product (authenticate you, generate AI responses, save your saved content)
- Keep the service safe (detect and block abuse)
- Reach you about your account (rare, only when needed)
We do not sell your data, share it with advertisers, or use it for behavioral advertising.
7. Data retention
We keep your account information until you delete your account. You can delete your account at any time from your account page; this removes your profile, saved homework history, lesson packages, course enrollments, and practice transcripts.
AI request logs at our hosting provider may persist for a short period as part of normal hosting operations.
8. Your rights
You can:
- Access what we have on you — visit your account page
- Delete your account and all associated data — one click on the account page
- Correct incorrect information — email
privacy@klass.app
If you live in California, the EU, or any jurisdiction with stronger data rights, those laws apply on top of what's described here.
9. Data security
We hash passwords with PBKDF2-SHA256 and a per-user random salt. Sessions use signed cookies. Traffic is encrypted in transit (HTTPS). No system is perfectly secure — if you suspect your account has been compromised, change your password and email us.
10. Changes to this policy
If we make material changes, we will post the new policy here and update the "Last updated" date at the top. For significant changes, we will email registered users.
