Privacy Policy
This policy explains what information the StockSim – Stock Market Simulator app ("StockSim", "we", "us") collects, why, who we share it with, and the choices you have. It applies to the StockSim apps for iOS and Android and to this website.
Short version: StockSim is a simulator. We never ask for your bank or brokerage details and never handle real money for trading. We use your information to run your account, improve the app, show ads to free users, and process subscriptions. We do not sell your personal information.
1. Information we collect
Information you give us
- Account details — your email address and, if you sign in with Apple or Google, the name and email those services share with us. Apple's "Hide My Email" is supported.
- Profile and settings — display name, preferences and notification choices.
- Messages to the AI coach — questions you type to the AI trading coach.
- Support requests — anything you send us by email.
Information created when you use StockSim
- Virtual trading activity — your virtual portfolio, orders, watchlist, lesson progress and competition entries.
- Usage data — screens viewed, features used, and in-app events, used to understand and improve the app.
- Device and diagnostic data — device model, operating system, app version, language, time zone, and crash and performance reports.
- Purchase data — which subscription or in-app purchase you have and its status. Payments are handled entirely by Apple or Google; we never see your card details.
- Push notification token — if you allow notifications.
- Advertising identifiers — for free users who see ads: the device advertising identifier (IDFA on iOS only if you allow tracking; AAID on Android) and related ad-interaction data. See section 4.
We do not collect precise location, contacts, photos, or financial account information.
2. How we use information
- To create and run your account and sync your virtual portfolio across devices.
- To provide features you ask for, such as live quotes, lessons, competitions and AI coach answers.
- To process and restore subscriptions and in-app purchases.
- To send notifications and emails about your account, lessons and offers. You can turn off marketing emails with the unsubscribe link and notifications in your device settings.
- To measure and improve the app, fix crashes, and test new features.
- To show ads to users who do not have a subscription, and to measure those ads.
- To keep StockSim secure and prevent abuse, and to meet legal obligations.
3. Service providers we share information with
We share information only with providers that help us run StockSim, under contracts that limit how they may use it:
| Provider | Purpose | Data involved |
|---|---|---|
| Supabase | Account and app database, hosting | Account details, virtual trading activity |
| Google Firebase | File storage | App content and files |
| Apple / Google sign-in | Sign-in | Name and email you choose to share |
| RevenueCat | Subscription management | Purchase status, an app user ID |
| Amplitude | Product analytics and feature testing | Usage data, device data, an app user ID |
| Sentry | Crash and error reporting | Diagnostic data |
| OpenAI | Generating AI coach answers | The questions you send and the stock context needed to answer |
| Google AdMob | Ads for free users | Advertising identifier, device data, ad interactions |
| Expo / Apple Push / Firebase Cloud Messaging | Push notifications | Push token |
We may also disclose information if required by law, to protect our rights or users' safety, or as part of a merger or sale of the app, in which case this policy continues to apply.
4. Advertising and tracking
Free users may see ads served by Google AdMob. Subscribers to StockSim Plus, and users who previously bought "Remove Ads", do not see ads.
- iOS: we ask for permission through Apple's App Tracking Transparency prompt before the advertising identifier (IDFA) is used. If you choose "Ask App Not to Track", you will still see ads, but they will not use your IDFA.
- Android: you can reset or delete your advertising ID, or opt out of personalized ads, in your device's Google settings.
- EEA, UK, Switzerland and certain US states: we show Google's consent message, where you can accept, refuse or manage personalized ads. You can change your choice later from the app's settings.
Google's use of data is described at policies.google.com/technologies/partner-sites.
5. We do not sell personal information
We do not sell your personal information for money. Under some US state laws, using advertising identifiers for personalized ads may be considered "sharing" or "targeted advertising"; you can opt out through the consent choices in section 4 or by emailing us.
6. How long we keep information
We keep account and virtual trading data while your account is active. When you delete your account, we delete or anonymize your personal information within 30 days, except where we must keep limited records (for example, purchase records required for tax or accounting). Analytics and crash data are kept in aggregated or pseudonymous form for up to 2 years.
7. Your rights and choices
- Access, correction, export: email us and we will respond within 30 days.
- Deletion: delete your account in the app (Settings → Delete Account) or follow the steps on our account deletion page.
- Marketing: unsubscribe from emails with the link in any message; turn off notifications in device settings.
- Ads and tracking: see section 4.
Depending on where you live (for example the EU/UK under the GDPR, or California under the CCPA/CPRA), you may also have the right to object to or restrict processing, to withdraw consent, and to complain to your local data protection authority. We will not discriminate against you for exercising these rights. Our legal bases for processing under the GDPR are: performing our contract with you (running your account), our legitimate interests (improving and securing the app), your consent (personalized ads, tracking, marketing), and legal obligations.
8. Security
We use encryption in transit, access controls and reputable infrastructure providers to protect your information. No method of transmission or storage is completely secure, but we work to protect your data and will notify you as required by law if a breach affects you.
9. International transfers
Our service providers may process information in the United States and other countries. Where required, transfers are protected by appropriate safeguards such as Standard Contractual Clauses.
10. Children
StockSim is not directed to children under 13 (or under 16 in the EEA and UK), and we do not knowingly collect their personal information. If you believe a child has given us personal information, contact us and we will delete it.
11. Changes to this policy
We may update this policy from time to time. We will post the new version here with a new effective date and, for material changes, notify you in the app or by email.
