This policy explains what we collect when you use breakouts.trade and how we use it. We collect only what we need to run the Service, and we do not sell your data.

• When you sign in with Google we receive your name, email, and profile image. We never receive your password.
• We store your drill results, scores, and settings to save your progress.
• We collect basic device and usage data through analytics and error monitoring to keep the Service working and improve it.
• If you subscribe, our payment processor handles your card details. We never see or store full card numbers.
• We share data only with the providers that run the Service (Google, Supabase, PostHog, Sentry, Stripe, Resend, and Twilio), each under their own privacy terms.

We use cookies and local storage to keep you signed in and remember your preferences. You can control cookies in your browser, though sign-in may stop working if you disable them.

Text message alerts (optional). If you opt in to text alerts, we collect your mobile number solely to send you the breakout notifications you requested. Message frequency varies, and message and data rates may apply. Reply STOP to unsubscribe or HELP for help at any time. We do not sell, rent, or share your mobile number or text-messaging opt-in with any third parties or affiliates for their own marketing or promotional purposes.

You can ask us to access, export, or delete your data at any time. We keep your account data while your account is active and remove it on request, except where the law requires us to keep it.

We may update this policy and will adjust the effective date above. Continued use means you accept the changes.
