Privacy Policy
Last updated: August 15, 2026
Summary: We collect the account, billing, and usage data needed to run the Propeller website, web app, and mobile companion app. We never sell your personal information.
1. Information We Collect
Propeller Picks ("Propeller," "we," or "our") collects and processes the following types of information:
- Account Data: When you create an account, we collect your email address, authentication credentials, and subscription status.
- Product Usage Data: When you browse props, save picks, or use the analyzer, we process the data required to provide those features, such as sport, game date, player, and stat selections.
- Device and Browser Information: We may collect browser type, device type, OS version, IP address, and crash or performance logs to keep the service reliable and secure.
- Subscription Data: Web subscriptions are processed securely through Stripe. Subscriptions purchased through the iOS or Android app are processed by Apple or Google. We receive subscription status and transaction metadata, but not full card details.
- Analytics: We use analytics tools to understand site traffic, product usage, and conversion performance so we can improve the service.
2. How We Use Your Information
We use the information we collect to:
- Provide AI-powered prop analysis and pick recommendations across supported sports
- Operate your account, subscription, and saved preferences across the web app and companion app
- Improve model quality, product performance, and conversion flows
- Monitor, prevent, and investigate technical issues, abuse, and fraud
- Send transactional emails or product notifications you opt into
3. Data Storage and Security
We store account, subscription, and product data with secure cloud infrastructure providers so the website, web app, and companion app can function properly. Some local preferences may also be stored in your browser or device.
API communications between your device and our servers are transmitted over HTTPS. We use access controls, logging, and infrastructure safeguards designed to protect your information, but no system is completely risk-free.
4. Third-Party Services
Propeller may interact with the following third-party services:
- Stripe: Web subscription payments and billing portal management. See Stripe's privacy policy.
- Apple App Store and Google Play: If you subscribe through a mobile app, the applicable store processes the payment under its own terms and policies.
- Google Analytics and PostHog: Usage and conversion analytics to improve the website and web app.
- Vercel and Railway: Hosting and application infrastructure providers for the web app and backend services.
- Sports Data APIs: We aggregate publicly available odds and player statistics from licensed data providers.
5. Disclaimer
Propeller provides informational sports analysis for entertainment purposes only. We do not facilitate, process, or handle gambling transactions. All betting decisions are made solely by the user on third-party platforms. Propeller does not guarantee any outcomes. Past performance does not guarantee future results.
6. Children's Privacy
Propeller is not intended for use by individuals under the age of 18. We do not knowingly collect data from minors.
7. Data Deletion
You can delete your account in the mobile app by opening More and choosing Delete Account. You can also request deletion by emailing support@propellerpicks.com from the address associated with your account. Full instructions and important subscription details are available on our public Delete Account page.
- Account deletion removes your Propeller account and account-owned data, subject to records we must retain for legal, security, fraud-prevention, or financial-reporting reasons
- A Stripe-backed subscription is canceled when its Stripe customer is deleted. Refunds are handled separately
- Apple App Store and Google Play subscriptions must be canceled separately through the store that billed you
- Clearing site data in your browser to remove local preferences stored on your device
- Deleting the companion app from your device if you no longer want local mobile data stored
8. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Your continued use of Propeller after changes constitutes acceptance of the updated policy.
