Privacy Policy

Last updated: July 6, 2026

This policy explains what StackCheaper ("we", "us") collects, why, and what you can do about it. We keep data collection to the minimum needed to run the service.

What we collect

• Account info — your email address (used for passwordless sign-in and to send the alerts you set up), and an optional display name.
• Your data in the app — the price alerts, watchlist items, and stack holdings you create. Your stack holdings are private to your account.
• Billing info — if you subscribe to StackCheaper Pro, payment is handled by Stripe. We never see or store your full card number; we keep only a Stripe customer/subscription reference and your plan status.
• Basic technical data — standard server logs (e.g. IP address, request time) needed for security, abuse prevention, and debugging.

Cookies

We use a single first-party cookie to keep you signed in. It's a functional cookie, not an advertising tracker, and we don't sell your data or use it for cross-site ad targeting. If we add analytics, we use a privacy-friendly, cookieless tool.

Service providers we share with

We share the minimum necessary with vendors that operate the service: Stripe (payments), Resend (sending email), and our hosting provider. TradingView charts are embedded on some pages and are subject to their own privacy terms. We do not sell your personal information.

Your choices

• Unsubscribe from alert emails using the link in any email, or by removing the alert in the app.
• Change your email anytime in Settings.
• Delete your account in Settings. This permanently removes your account and associated data (alerts, watchlist, stack).

Data retention & security

We keep your data for as long as your account is active and delete it when you delete your account. We protect it with reasonable technical measures.

Changes & contact

We may update this policy; material changes will be reflected by the date above. Questions or requests: [email protected].
