Privacy Policy

Effective Date: July 23, 2026

DuoFaith ("the App") is developed by Luke Downie ("we," "us," or "our"). This Privacy Policy explains how the App handles your information. We built DuoFaith with privacy as a core principle — we collect only what is necessary to make the App work, and we never sell your data.

Information Stored on Your Device

DuoFaith stores the following information locally on your device using Apple's SwiftData framework:

Your first name (entered during onboarding)
Your chosen lock time (hour and minute)
Devotional progress (current streak, total devotionals completed, date of last devotional)
Reading plan progress
Onboarding completion status
Pro/Free plan status

This on-device data is not transmitted to any external server.

Couples Mode (Pro Feature)

If you choose to use Couples Mode, the App connects to a secure server (hosted by Supabase) to enable pairing and shared progress with a partner. When you use Couples Mode, the following data is transmitted and stored on our server:

An anonymous user identifier (no email, phone number, or personal account is created)
Couple pairing records (linking two anonymous users)
Daily devotional completion records (so your partner can see when you've finished)
Nudge records (when one partner sends a reminder to the other)
A shared streak counter

This data is associated with an anonymous identifier only. We do not link it to your name, email, or any other personally identifiable information. If you do not use Couples Mode, no data is sent to any server.

Push Notifications

If you enable Couples Mode, the App may register a device token with Apple's Push Notification service to deliver nudge notifications from your partner. This device token is stored on our server and is used solely for delivering notifications. The App also schedules local notifications (reminders and streak alerts) that are handled entirely on your device.

Screen Time and Family Controls

DuoFaith uses Apple's Screen Time API (Family Controls / Managed Settings) to shield selected apps until you complete your daily devotional. The App requests your authorization to use these system frameworks. App-shielding selections are handled entirely by Apple's on-device APIs — we never see or transmit which apps you choose to shield.

Subscriptions

DuoFaith uses RevenueCat to manage in-app subscriptions. RevenueCat processes your subscription status through Apple's App Store and may receive an anonymous app user identifier to manage entitlements. RevenueCat does not receive your name or any other personal information from DuoFaith. For more information, see RevenueCat's Privacy Policy.

Bible Passages

The App may fetch Bible passages from a third-party API (bible-api.com) to display daily devotional content. These requests do not include any personal or identifying information. If the service is unavailable, the App uses built-in devotional content instead.

Data We Do NOT Collect

DuoFaith does not:

Require you to create an account with an email, phone number, or password
Use analytics, tracking, or advertising SDKs
Collect location data
Share or sell data with third parties for advertising or marketing
Use cookies or web-based tracking
Track which apps you choose to shield

Data Retention and Deletion

On-device data is stored for as long as the App is installed. You can delete your on-device progress at any time using the "Reset Progress" option in Settings. To delete all local data, uninstall the App.

If you have used Couples Mode, you can unpair from your partner within the App, which removes the active couple relationship. You can also delete your account entirely from Settings, which removes all server-side data associated with your anonymous identifier, including completion records, nudge history, and device tokens.

Children's Privacy

DuoFaith does not knowingly collect personal information from children under 13. The App's Couples Mode uses anonymous authentication and does not require any information typically associated with children's privacy concerns (no email, no real name transmitted, no location).

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the App after changes constitutes acceptance of the revised policy.
