Privacy Policy

• Your email address, when you create an account. It identifies your account and is used to sign you in and to contact you about your subscription if needed.
• Subscription state, if you go Pro. Payments are handled by our billing providers (RevenueCat, Stripe, and the Apple App Store). We store only whether your subscription is active and until when — never your card number or full payment details.
• Basic server logs. Like any website, our servers record standard request information (such as IP address and timestamps) for security and reliability. These are not used to build a profile of you.
• Anonymous usage analytics. We record which pages are viewed and a few basic actions (such as running a simulation or sharing a result), tied to a random device identifier — never to your name, email, or account. This data is stored on our own servers; no third-party analytics service is involved.

• No advertising.
• No third-party analytics or tracking SDKs.
• We don’t sell, rent, or share your personal data.

Your email and subscription state are used only to run your account and your subscription. We share data with our billing providers strictly to process your payment and keep your subscription status accurate.

You can delete your account and its associated data at any time from within the app, on your Account screen. Deletion removes your account and email; your subscription record is removed along with it. If your subscription is still active through the App Store or another platform, cancel it there as well so you aren’t billed again.

If you’d rather we handle it, email [email protected] and we’ll delete your account for you.
