Privacy Policy

Effective Date: September 30, 2026 · Last Updated: October 1, 2026

StockClash ("we," "our," or "the App") is a stock market game operated by Zackery Atlas. This policy explains what the App and the stockclash.io website collect, why, who processes it on our behalf, and how to delete it.

The short version: you can play without an account, and then your progress stays on your iPhone. If you create an account, we store your email, username and game data so your progress, streak and rankings follow you. We record how the App is used and when it crashes so we can fix it. We do not show ads, we do not track you across other apps or websites, and we do not sell your data.

1. Information We Collect

If you play as a guest: nothing that identifies you leaves your device, except what you choose to share (for example a challenge link) and purchase records handled by Apple and RevenueCat (see below). Your progress, settings and streak are stored on your iPhone.

Account information (only if you create an account): your email address, the username you choose, the experience level you pick during setup, and a randomly generated account ID. If you use Sign in with Apple, we receive an Apple identifier and the email you choose to share, which may be an Apple private relay address. Passwords are handled by our authentication provider, Supabase, and are stored hashed; we never see them.

Gameplay data (signed in): the rounds you play, your trades, returns, scores, ranks, streaks, XP, badges, campaign and Vault progress, tournament entries, the players you follow, and a backup of your in-app progress so it can be restored on another device.

Product events and crash reports: the App records in-app events such as opening the App, screens viewed, rounds started, quit and finished (with the era and your return), paywall views, purchase results, shares and follows, together with a random session ID, the App version and the platform. When the App hits an error it records the error message and a technical stack trace. When you are signed in, these are stored in our own database (hosted by Supabase) and linked to your account ID. While you play as a guest they stay on your device; if you later sign in on that device, the most recent ones are sent with your account. We do not use a third-party analytics or crash-reporting service.

Purchases: StockClash Pro is sold through Apple. We receive your subscription status (active or not, plan, renewal dates) from Apple through RevenueCat. We never receive your card or payment details.

Notifications: the Today's Market reminder is scheduled locally on your iPhone; turning it on sends nothing to us. If you enable push notifications, we store your device's push token on your account so we can send them, and remove it when you sign out or turn them off.

Support emails: if you email us, we receive your email address and whatever you write.

Website waitlist: if you join the waitlist on stockclash.io, we store your email address and the page you signed up from.

2. Information We Do Not Collect

• Real financial account information (bank accounts, brokerage accounts, credit cards)
• Social Security numbers or government IDs
• Location data, contacts, photos, or your phone number
• Health or biometric data
• The advertising identifier (IDFA) or browsing history outside the App

StockClash is a game. All trading is simulated with virtual money on historical prices. No real money is at risk, and no real financial data is processed.

3. How We Use Your Information

• To run the game: save your progress, score your rounds, compute leaderboards, streaks, badges and tournaments, and restore your progress on a new device
• To provide StockClash Pro to subscribers and restore it on your devices
• To find and fix bugs and crashes, and to understand which parts of the game people play
• To detect and prevent cheating and abuse
• To answer you when you contact us, and to email waitlist members when the App launches

We do not use your information for advertising, and we do not combine it with data from other companies to build a profile of you.

4. Who Can See It, and Who Processes It

Other players: your username, rank, scores, streak and profile stats are visible to other players on leaderboards, in tournaments and to players who follow you. Your email is never shown to other players.

Service providers that process data on our behalf, only to run StockClash:

• Supabase — our database, sign-in and server functions. Stores your account, gameplay data, product events and crash reports.
• RevenueCat — manages subscriptions. Receives an app user ID (a random anonymous ID, or your StockClash account ID once you sign in), your purchase and subscription status from Apple, and basic device information needed to validate purchases.
• Apple — processes all payments through the App Store, and Sign in with Apple if you use it.
• Expo — delivers push notifications, only if you enable them.
• Vercel — hosts the stockclash.io website and receives your IP address when you visit it.

Legal requirements: we may disclose information if required by law or to protect the safety of our players.

We do not sell or rent your personal information, and we do not share it for cross-context behavioral advertising.

5. Storage and Security

On your device: the App keeps your progress, settings and, if you are signed in, your sign-in session in the App's private on-device storage. It is removed when you delete the App.

On our servers: data is stored with Supabase, encrypted in transit (TLS) and at rest. Row-level security limits each account to its own private data. No system is perfectly secure, but we take reasonable measures to protect your information.

6. Data Retention and Deletion

• Account and gameplay data is kept while your account exists.
• Deleting your account (in the App: Settings → Delete Account) deletes your sign-in, email, username, profile, game history, progress backup, follows and tournament entries from our live database right away. Copies in our database backups expire on their normal schedule, within 30 days.
• Product events and crash reports are detached from your account when you delete it and kept only in that de-identified form to help us improve the App.
• Purchase records are kept by Apple and RevenueCat under their own policies. Deleting your account does not cancel an active subscription; cancel it in your iPhone's Settings. Email us if you would also like RevenueCat's records for your account deleted.
• Waitlist emails are kept until launch and deleted on request.

7. Your Choices and Rights

• Play without an account: everything in the game can be played as a guest.
• Access and correct: your profile, history and progress are visible in the App. Email us for a copy of your data or to correct it.
• Delete: Settings → Delete Account in the App, or email us and we will delete it for you.
• Notifications: turn reminders off in the App's Settings or in your iPhone's Settings at any time.

Depending on where you live (for example in the EU, UK or California), you may have additional rights to access, correct, delete, or port your data, or to object to its use. We honor these requests for everyone. To make one, email hello@stockclash.io. We will not discriminate against you for exercising them.

8. Children

StockClash is intended for players 13 and older (see Terms of Service §2). We do not knowingly collect personal information from children under 13. If you believe a child under 13 has created an account, email us and we will delete it.

9. International Processing

StockClash is operated from the United States, and our service providers may process data in the United States and other countries. By using the App you understand that your information may be processed outside your country.

10. Changes to This Policy

If we change this policy we will update the date above, and we will tell you in the App or by email before a material change takes effect.
