Frequently asked questions
Why does the app need permanent location access?
CallWatcher needs to check your connection in the background — even when the screen is off. iOS and Android only keep the app reliably active when location can be queried permanently. That's why the "Always allow" permission (iOS) or "Allow in background" (Android) is required.
If you only choose "While using", monitoring only works while the app is open.
How do groups and handovers work?
A group bundles multiple people who take turns being on call. Exactly one member holds the on-call duty at any given time. Through the handover function you ask another member to take over. As soon as they accept, the on-call role switches.
To join a group you need the join code shared by the group admin.
How much is Premium and how do I cancel?
Premium is available as a subscription. You'll see the current price inside the app under "Premium". Billing is handled by Apple (iOS) or Google (Android). You cancel directly in the App Store or Play Store under your subscriptions — we can't end the subscription for you.
How do I delete my account and all data?
In the app: Settings → Account → Delete account. All your data will be removed irreversibly.
Alternatively write to info@callwatcher.app — we'll delete your account and all data within 30 days.
Why do I only see "--" as my mobile carrier?
Since iOS 16.4, Apple disabled the interface for reading the carrier name. This information is no longer available system-wide — Apple has not provided a replacement.
The Live Activity turns grey or disappears — why?
iOS only grants a Live Activity a limited lifetime and freezes it when it isn't updated regularly. CallWatcher refreshes the display every 30 seconds. If it greys out anyway, briefly opening the app brings it back instantly.
Where is my data stored?
We use Firebase (Google Ireland Ltd.). Data is primarily processed in EU data centres. Details are in our privacy policy.
My schedule isn't showing — what can I do?
Make sure you're signed in. Schedules are stored locally and synchronised with the cloud on the next sign-in. If the problem persists, closing and reopening the app usually helps.
