Privacy Policy
Effective 11 October 2026
Short version: the blocking runs entirely on your device. Your contacts, calls and messages are never collected, uploaded or sold, and there is no account. The free version shows advertising from Google; Nixring Pro removes it. Blocklist updates and optional app recommendations also use a connection as described below.
1. Our approach
Nixring: Spam Call Blocker ("Nixring", "the app", "we") is built to protect your privacy by design. The entire purpose of the app is to block unwanted calls and texts without uploading your contacts, calls or messages.
2. Information we do not collect
We want to be completely clear about what Nixring does not do:
- We do not collect, store, or transmit your contacts.
- We do not collect your call history or the phone numbers that call or text you.
- We do not read the content of your calls or messages.
- We do not use third-party data brokers, and neither the Call Directory extension nor the Message Filter extension contains any advertising or analytics code. Advertising in the free version of the app is described in section 6.
- We do not require an account, email address, or login.
3. How blocking works on-device
Nixring uses Apple's Call Directory and Message Filter extensions. Nixring provides iOS with a blocklist of known spam and scam numbers, and iOS itself performs the blocking. This all happens locally on your device inside Apple's secure system framework. The numbers that call or text you are handled by iOS and are never seen by us or sent anywhere.
4. Data stored on your device
The spam blocklist and your app settings (for example, which categories you have enabled) are stored locally on your iPhone. This data stays on your device and is removed when you delete the app. It is never uploaded.
5. Subscriptions and payments
Nixring offers an optional auto-renewing subscription. All purchases and subscription management are handled by Apple's App Store and StoreKit. We never see or store your payment details. Apple's handling of your purchase is governed by Apple's Privacy Policy.
6. Advertising in the free version
The free version of Nixring shows advertising supplied by Google AdMob. Google receives the technical data it needs to serve and measure an ad, which can include the Apple advertising identifier where you have allowed tracking, plus device and usage data. This is why the App Store privacy label for Nixring lists identifiers and usage data. Tracking requires your permission through Apple’s App Tracking Transparency prompt. Declining tracking does not prevent the technical data processing needed for non-personalized ads. You can manage advertising consent under Advertising privacy choices in the app settings and tracking permission in iOS Settings.
Nixring Pro contains no Google AdMob advertising. Recommendations for our other apps remain available as described below. In both versions the advertising code lives only in the main app: the Call Directory and Message Filter extensions contain none of it, so nothing about your calls or messages is ever available to an advertising provider.
Recommendations for our other apps
In Settings, the app can fetch up to three recommendations for our other apps. The choices depend on the app you are using, App Store availability and iOS compatibility, not on your personal data or activity inside the app. App icons load from Apple’s image servers. Opening a recommendation takes you to the App Store with a campaign label identifying the source app and placement, never a person.
We count qualified views and successful opens in aggregate. Our service stores daily counts with the source app, recommended app, placement, configuration revision and optional presentation variant. It does not store an account, advertising identifier, device identifier, persistent visitor identifier or personal profile, and it does not receive the app’s private content. These counts cannot tell us who installed an app.
The recommendation service is hosted by Supabase. Network requests necessarily expose an IP address to the hosting provider for delivery and security; our aggregate counter does not store it. See Supabase’s privacy policy. Apple processes icon requests and App Store visits under Apple’s privacy policy.
7. Blocklist updates and this website
With Nixring Pro the app downloads one public file, blocklist.json, to refresh the spam list. Every user downloads the same file without an account or persistent user identifier. The hosting provider necessarily receives an IP address to deliver the file and secure the service.
The marketing pages of this website use Vercel Web Analytics, which counts page views and clicks on the App Store link without cookies and without building a profile of you. The privacy, support and terms pages carry no measurement at all.
8. Children's privacy
Nixring does not knowingly collect information from children. The app has no account, asks for no personal details, and never reads your contacts, calls or messages. Advertising in the free version is described in section 6; Nixring Pro removes it. Optional recommendations use aggregate counts as described above.
9. Changes to this policy
If this policy ever changes, we will update this page and revise the effective date above. Material changes will be reflected in an app update.
