Privacy Policy

1. Our privacy philosophy

Big Screen Bible exists to help people engage deeply with Scripture. We believe Bible study should be accessible, distraction-free, and respectful of your privacy.

We aim to collect only the information reasonably needed to provide accounts, synchronize supported study data, maintain the service, and protect its security.

2. Information we handle

Information stored on your device

Big Screen Bible uses browser local storage so the app can remember your choices and study work. Depending on the features you use, this can include:

• Selected Bible translations, theme, font, text size, layout, display, startup, toolbar, and accessibility-related preferences.
• Bookmarks, notes, highlights, recently opened Scripture references, and reading-streak dates and totals.
• Game type, category, difficulty, round-length, sound, and timed-mode preferences, plus Book Sprint best times.
• Interface state, such as whether a panel, tutorial, or navigation bar has been opened or collapsed.
• Optional notification status, morning and evening reminder times, timezone, and a device token used to manage that browser’s push subscription.

This device data exists even if you do not create an account. It stays in that browser or app web view unless it is cleared, overwritten, or synced to an account as described below.

Account and sign-in information

If you create an email-and-password account, your email address and password are sent to Supabase Auth for account creation and sign-in. Supabase assigns a user ID and records the sign-in provider. Big Screen Bible's sync table uses the Supabase user ID; it does not contain your password.

If you choose Google Sign-In, Google sends Supabase the information allowed by the Google sign-in flow. The resulting Supabase authentication record may include your email address, name or display name, avatar URL, Google or provider identifiers, provider name, and Supabase user ID. The current Big Screen Bible interface reads the user ID for data sync and the email address for the account display. It does not currently display or otherwise use your name or avatar.

Supabase also stores the authentication session needed to keep you signed in and refresh your session.

Optional push-notification information

If you enable daily reminders, Big Screen Bible stores a push-subscription endpoint and its browser-generated encryption keys, a one-way hash of the device-management token, your browser-reported timezone, your chosen reminder times, whether the evening reminder is enabled, the last time that device opened Big Screen Bible, and the local dates on which reminders were sent. A Big Screen Bible account is not required for this device-specific subscription.

The last-opened time is used only to suppress the optional evening reminder when that device has already opened Big Screen Bible during its local day. The push endpoint is treated as sensitive and is not exposed through the public database API.

Account-synced study data

When you are signed in, Big Screen Bible syncs one private data record associated with your user ID. It can contain:

• App settings, including selected translations, appearance, reading, display, startup, and game preferences.
• Bookmarks, notes, highlights, reading history, and reading-streak information.
• The date and time when the sync record was last updated.

Book Sprint best times and certain interface-only state are currently kept on the device and are not included in the cloud-sync record.

Requests to remote Bible services

When you use a remotely supplied Bible translation or remote search, the requested Scripture reference, translation, or search text is sent through a Supabase Edge Function to the relevant Bible provider. When an API.Bible translation is viewed, the app also sends the provider's FUMS usage token through API.Bible's required reporting script. If you are signed in, the current code configures that reporting script with your Supabase user ID.

Service providers that deliver the website or a requested feature may receive ordinary technical request information, such as an IP address, browser or device details, and request time. Big Screen Bible does not add its own general-purpose analytics tracker.

3. Browser storage and cookies

Big Screen Bible uses local storage for saved study data and preferences. If you enable notifications, local storage also keeps that device’s reminder choices and management token. Supabase's browser client is configured to persist and refresh sign-in sessions, which means authentication session data is also kept in browser storage.

The Big Screen Bible application code does not directly set advertising or analytics cookies. Google, Supabase, GitHub, font or content-delivery services, and Bible providers may use their own cookies or similar technologies when you visit their pages, sign in, or load their resources. Those services control their own technologies and policies.

4. How information is used

Information is used to:

• Create and authenticate accounts, send confirmation or password-reset messages, and keep sessions signed in.
• Save your preferences and restore your reading and study workspace.
• Sync settings, bookmarks, notes, highlights, history, and streaks across signed-in devices.
• Load requested Scripture text, search results, Verse of the Day content, fonts, Strong's dictionaries, and optional game celebration code.
• Schedule and deliver optional Verse of the Day reminders and suppress the evening reminder after the subscribed device has opened the app that day.
• Meet Bible-provider licensing, attribution, and usage-reporting requirements.
• Protect, maintain, troubleshoot, and improve the service.
• Respond to support, privacy, and account requests.

5. Third-party services

Big Screen Bible currently relies on the following types of third-party services:

• Supabase: authentication, account sessions, the user-sync database, and server-side Edge Functions.
• Browser and operating-system push services: delivery of notifications through the push service selected by your browser or device, which may be operated by Apple, Google, Mozilla, Microsoft, or another browser provider.
• Google: optional Google Sign-In and Google Fonts. Google Sign-In is only used if you choose it.
• GitHub Pages: static website hosting for bigscreenbible.com.
• Bible content providers: Crossway's ESV API, API.Bible for supported licensed translations, and YouVersion Platform for supported YouVersion content.
• API.Bible FUMS: provider-required Scripture usage reporting for API.Bible translations.
• VerseoftheDay.com and its FeedBurner feed: the Verse of the Day source and source links.
• jsDelivr: delivery of the Supabase browser library, optional game-confetti code, and optional Open Scriptures Strong's dictionaries.

Some Bible text, reference data, and Strong's resources are bundled with the application and do not require a network request to their original source during ordinary use. Third-party services have their own terms, privacy policies, and retention practices.

6. Sharing, sales, and advertising

Big Screen Bible does not sell personal information and does not use personal information for targeted advertising.

Information is shared with service providers only as needed to provide the features described in this policy, comply with Bible-content licensing and usage-reporting requirements, respond to a valid legal obligation, protect the service or its users, or complete a change in who operates the service.

7. Data retention

Data in local storage remains on your device until you clear the site's or app's stored data, remove or replace the saved item, or your browser or operating system clears it.

Account information and synchronized study data are retained until you request deletion, the account is deleted, or retention is otherwise needed for legitimate legal, security, or operational reasons. Big Screen Bible does not use a fixed retention schedule for this data.

An optional push subscription is deleted when you turn reminders off and the unsubscribe request reaches the service. Invalid or expired push subscriptions are also removed when the push service reports that they can no longer receive notifications.

8. Your choices and requests

You can use the main Bible-reading features without an account. You can edit or remove individual notes, bookmarks, highlights, and history within the app, and you can clear local data through your browser or device settings. Signing out ends the active account session but does not by itself delete local or cloud data.

You can turn daily reminders off in Big Screen Bible Settings or revoke notification permission in your browser or operating-system settings. Reminder times and subscriptions are device-specific.

You may email support@bigscreenbible.com to request access to, correction of, or export of your information. You may also request deletion of your account and its associated synchronized study data.

Account deletion is currently handled by request because an automated deletion interface is not yet available. We may need to verify that you control the account before completing a request. Deleting an account does not automatically clear data stored locally in your browser or app; you can clear that data through your browser or device settings.

Requests are handled subject to applicable law and technical or provider limitations.

9. Security

The sync database is configured with Supabase Row Level Security rules intended to limit signed-in users to their own sync record. The push-subscription table also has Row Level Security enabled and is not granted to anonymous or signed-in browser roles; only server-side functions manage it. Provider and push-sender secret keys are kept in server-side Supabase functions rather than in the website's public code.

No internet service, browser storage system, or database can be guaranteed completely secure. Please use a strong, unique password, protect access to your email and devices, and sign out on shared devices.

10. Children's privacy

Children should use Big Screen Bible with the permission and supervision of a parent, legal guardian, or teacher, especially when creating an account or saving study information.

A parent or legal guardian may contact support@bigscreenbible.com with questions or requests concerning a child's information.

11. Changes and contact

This policy may change as Big Screen Bible adds or changes features, providers, or legal requirements. The effective and last-updated dates at the top will be revised when the policy changes. Material changes may also be announced in the service when practical.

Questions or privacy requests can be sent to support@bigscreenbible.com.
