Privacy Policy

Effective date: April 20, 2026 Last updated: April 20, 2026


1. Who we are

Steward Technologies ("Steward," "we," "us," "our") operates the Steward iOS application (the "App"), which helps you decide which of your credit cards to use based on nearby merchants, your spending profile, and loyalty memberships.

2. What this policy covers

This policy describes the personal information the App collects, how we use it, who we share it with, and the choices you have. It covers the mobile app, our backend API, and the lock-screen widget.

Contact support@stewardflow.com.

8. Children

Steward is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe we have, contact support@stewardflow.com and we will delete it.

9. Security

We encrypt data in transit using HTTPS/TLS. Our database is operated by Railway with provider-managed backups. Your Apple identifier is stored on our servers; any authentication tokens are stored in the iOS Keychain on your device. No system is perfectly secure, but we use standard industry practices and commit to disclosing breaches to affected users as required by applicable law.

10. Third-party links and data

The App may link out to issuer websites or mapping services. Those services have their own privacy policies; this policy does not cover them.

11. Beta testing disclosure

During the initial TestFlight beta (April 2026), the App may log additional diagnostic information to help us identify and fix issues. This information is used only to improve the App, is not shared with advertisers, and is deleted on the same cadence as our regular logs.

12. Changes to this policy

We may update this policy as the App evolves. Material changes will be announced in-app or via email. The "Effective date" at the top reflects the latest version.
