Privacy Policy — Stonk Arena

Last updated: June 2026

What we collect

• Account data: your email address and chosen player name (via Firebase Authentication, a Google service).
• Game data: your virtual portfolio value, return percentage and number of trades, stored to display the leaderboard.
• Local data: your portfolio and settings are stored on your own device.

What we don't do

• We do not sell your personal data.
• No real money is deposited, invested or at risk: all trading is simulated with virtual capital. The monthly winner does receive a real cash prize (currently €100), paid by SEPA bank transfer — see the Terms of Service.

Advertising, affiliate links & analytics

• Stonk Arena may display advertisements and affiliate links (for example to brokers or financial services). If we work with advertising partners, those partners may use cookies or device identifiers to measure or personalise ads; where required, we will ask for your consent first.
• We may use analytics to understand how the app is used and to improve it.
• This policy will be updated whenever we introduce new advertising or analytics partners.

Data processors

Authentication and database services are provided by Google Firebase. Their processing is covered by the Firebase Privacy documentation.

Your rights

You can have your account and all associated data deleted at any time by emailing support@stonkarena.net; we process deletion requests without undue delay and at the latest within 30 days. To keep the monthly competition fair, a pseudonymised record (a hash of your email address linked to your current month's result) may be retained until the end of the running month, after which it is automatically deleted. EU users have the rights provided under the GDPR (access, correction, deletion, objection).

Children

Stonk Arena is a free simulation game: playing never involves deposits, stakes or gambling. The monthly €100 prize is a promotional reward paid out to the winner in real money, as described in the Terms of Service.
