The One Church app gives each member their own set of controls for how the app looks, what language it speaks, how it gives feedback, and whether it locks behind Face ID or a fingerprint. None of this is set by the church. These screens are the app's own, and they look the same in every church's app, so anything below can be walked through with a member over the phone.
There are two screens, and the difference matters when you are helping someone find a setting:
Settings - the top-level screen. It holds the church selection, the link into Preferences, the app's legal pages, the diagnostics screen, and the profile-deletion request.
Preferences - one row inside Settings. It holds appearance, language, feedback, accessibility, the app lock, and the app's permission rows.
The Settings screen
How to access Settings
Tap the 3-bars menu in the top left of the app to open the side menu.
Scroll down to the footer of the menu.
Tap Settings.
The Settings screen holds:
Church - shows the church that is currently selected. Tapping it confirms, then returns the member to church search so they can pick a different one.
Preferences - opens the Preferences screen described below.
App Preview - appears for app-builder admins only. It takes a code from the app builder so staff can view an unpublished design on a real device.
About this app - the diagnostics screen. See the next section.
Terms of Use and Privacy Policy - open the One Church Software pages inside the app.
Request profile deletion - appears only when the member is signed in, and disappears while a request is already pending.
The Preferences screen
Choose a theme and a language
Open Settings > Preferences and use the Appearance section.
Theme - choose System, Light or Dark. The church picks the app's colors, and the app builds a matching light palette and dark palette from them, so a church never has to design a dark mode of its own.
Language - choose English, Español or 한국어. Each option is listed in its own language. The whole app repaints as soon as one is selected.
Tip: A member may see a mix of languages. The app's own wording is translated by One Church, while screen names and text the church wrote are translated by the church in the app builder. Where the church has not translated a field yet, the app falls back to text it does have rather than showing a blank label. The fix is for the church to finish translating in the builder.
On a brand new install the app follows the device's language. After a member picks a language here, it follows their choice instead.
Adjust feedback and accessibility
These settings also live on the Preferences screen.
Haptics - turns the small vibrations on taps and confirmations on or off.
Reduce Motion - cuts back on animation. The app also honors the device's own reduce-motion setting.
Text Size - shows the current size and sends the member to the device's setting, because text size belongs to the operating system rather than to the app.
Tip: On Android the Text Size row opens the system display settings directly. On iOS it names the path and offers to open Settings, because Apple provides no way to jump to that specific pane. The iOS paths are Settings > Display & Brightness > Text Size, or Settings > Accessibility > Display & Text Size > Larger Text for the largest sizes.
Content in the app scales with the member's chosen text size. Navigation labels and menu rows are capped so the layout still holds together at the largest accessibility sizes.
Lock the app with Face ID or a fingerprint
A member can require a biometric unlock every time they come back to the app. The row sits in the Security section of Preferences and is named after the method the device offers, so it reads Require Face ID, Require Touch ID or Require Fingerprint.
Sign in to the app. The app lock is available to signed-in members only.
Open Settings > Preferences and find the Security section.
Turn on the Require Face ID row, using whichever method the device names.
Complete the biometric challenge when the device asks. The app will not arm a lock the member cannot open.
With the lock on, two things change. While the app is in the background, an opaque branded panel covers it so nothing shows in the device's app switcher. When the member returns, a lock screen appears reading One Church is locked with an unlock button and a Sign out option.
The app lock is per device. Turning it on for a phone does nothing to the same member's tablet. The row does not appear at all on a device whose hardware does not support biometrics.
Check the app's permissions
The App Permissions section of Preferences holds three rows, each showing the device's live answer as Granted, Denied or Unknown, with a hint underneath and a tap that takes the member where the setting can be changed.
Push Notifications - opens the app's Notifications screen, where the member can also set channels and quiet hours.
Camera - used for taking a profile photo and for scanning.
Location - used by church search.
Tip: When a member reports that the app cannot use their camera, location or notifications, have them read these three rows aloud. The live status settles most of those reports in one step.
Find diagnostics on the About this app screen
Open Settings > About this app. This is the screen to send a member to when you need details about their device before you can help. It lists:
App version, Operating system, OS build, and the platform's API level.
Device - the device model.
Runtime version - which app build the member is running.
Church ID - the church's short identifier. This is the fastest way to confirm which church an app is pointed at.
Push token - needed for any report about notifications not arriving.
A copy action in the header of that screen puts every row on the clipboard as labeled lines. Ask the member to tap it and paste the result into their support conversation. It is one tap and it supplies everything at once. Individual rows also copy when tapped.
Tip: If the Push token row shows a dash instead of a value, the device has no push token registered, so no notification could reach it whatever the church sends. On a report about missing notifications, check that row first.
