Privacy Policy
Last updated October 19, 2026
Paperfolio is an educational paper-trading app run by the Paperfolio team. Everything in it is a simulation: no real money is ever deposited, invested or traded. This policy explains what information the app collects and how it's used.
What we collect
- Account details: your name, username, email address and password (stored securely by our login provider, never in plain text).
- Optional profile details: school and a short bio, if you add them.
- Your activity in the app: paper trades and orders, watchlist, portfolio history, journal entries, lesson and quiz progress, club membership, and posts, comments, votes and reports you make in clubs.
- AI Coach questions: the messages you send to the AI Coach, and (if you choose) a summary of your paper portfolio or a stock, so it can answer.
We don't collect your location, contacts, photos, or any real bank or payment information. We don't use advertising or tracking tools, and we don't sell your information.
How it's used
- To run your account and paper portfolio, save your progress, and show leaderboards and club competitions.
- To show your name, username, and (if you make your portfolio public) your paper returns to members of clubs you join.
- To keep clubs safe: reviewing reported content and enforcing our Terms of Use.
Services we use
- Supabase: secure database and login.
- Vercel: hosts the app.
- Finnhub (and optionally Alpha Vantage): stock prices and company data. Only ticker symbols are sent, never your personal information.
- OpenAI: powers the AI Coach. Your coach messages are sent to OpenAI to generate a reply. Don't share personal or sensitive information with the coach.
Who can see your information
Other members of a club can see your name, username, avatar, posts and comments in that club, and your paper portfolio if you leave “public portfolio” switched on in your profile. Your journal, email and AI Coach chats are private.
Keeping and deleting your data
We keep your information while your account exists. You can delete your account at any time in the app: Profile → Delete account. This permanently removes your login, portfolio, trades, journal, lessons, posts and comments. Clubs you run are handed to another member. Server backups may keep copies for a short time before they're overwritten.
Age
Paperfolio is meant for high-school and college students aged 13 and older. If you're under 13, please don't create an account.
Security
Data is sent over encrypted connections, and the database only accepts requests from our server. No system is perfectly secure, so use a password you don't use elsewhere.
Changes and contact
If this policy changes, we'll update the date above. Questions or requests: [support email not set: add NEXT_PUBLIC_SUPPORT_EMAIL].
