CallBlocker privacy
All Nighter Labs makes CallBlocker. This page explains data handling in version 1.1 of the app and on this website. CallBlocker is on the App Store.
Screenshots, recordings and on-device reading
You choose screenshots or a screen recording through Apple's photo picker. CallBlocker reads the phone numbers visible in them on your device, with Apple's on-device text recognition, and keeps what it read in a local database: each number, how often it appeared, and what the Recents row showed beside it, such as the day, the time and any caller ID label. It groups those numbers into the ranges it suggests. Where Apple Intelligence is available, Apple's on-device model writes the sentence beside each range; that runs on the device too.
None of this is sent to All Nighter Labs, to Apple's servers or to any other service. CallBlocker cannot open the Phone app's own history and does not listen to calls.
The app makes a temporary local copy of each chosen item for reading and removes the copy when it finishes. The originals stay in Photos until you delete them. Clear Imported Call Logs, in the Review tab's menu, deletes everything the app read. Your own iCloud Photos and iCloud Backup settings may copy screenshots, recordings or app data to Apple independently of CallBlocker.
Block rules and iCloud
Rules are stored on the device and shared with the app's iOS blocking extension. When iCloud is available, CallBlocker syncs each rule's pattern, label, on/off state, creation date and source (from import, added by you, or added with Shortcuts) through the private CloudKit database attached to your Apple Account, so your other devices get the same rules.
A rule can be a single number or a range, so the numbers in your rules do leave the device through sync. The imported numbers, labels, screenshots and recordings never do. The private database is yours; All Nighter Labs cannot read it.
App accounts and analytics
You do not create a CallBlocker account. The app does not include advertising or send usage analytics to All Nighter Labs. Apple manages any Apple Account services you use, such as iCloud and App Store purchases, under Apple's own terms and privacy practices.
This website
The site has no account form and no advertising scripts. Its fonts, images and page scripts are served from this website, so loading a page does not request fonts from Google or contact an external AI service. Following an external source link takes you to that provider's website.
The site does use Google Analytics to count visits and see which pages people read. It loads a script from googletagmanager.com and stores a cookie in your browser that gives your device a random identifier. It records the pages you view, an approximate location derived from your IP address, and your browser and device type. Google drops the IP address itself before storing the visit. Advertising features, ad cookies and Google Signals are switched off, so this data is not used to build an advertising profile or shown to advertisers. Blocking the script in your browser, or a tracking-protection or Do Not Track setting that blocks it, leaves the rest of the site working normally.
Serving a web page also exposes normal connection information, including an IP address and requested URL, to the hosting service. Any server logging depends on the hosting configuration. App processing and website requests are separate data flows.
Email support
If you contact support@callblockerios.com, All Nighter Labs receives your email address and whatever you include in the message. We use that information to answer your request. Avoid sending recordings, full call histories or other people's phone numbers unless they are needed to explain your issue.
Managing your information
You can switch off or delete rules on the Rules tab, clear imported call logs from the Review tab's menu, and manage the original screenshots and recordings in Photos. Deleting a rule on one device removes it from your other devices through iCloud. Deleting a screenshot does not delete a rule made from it. Removing the app does not necessarily remove its iCloud data or existing backups; manage those through your Apple Account and iCloud settings.
For questions about data handling or information you have sent to support, email support@callblockerios.com. We will update this page when the app's or website's data practices change.
