BlockbirdPrivacy Policy
Blockbird is an ad blocker for iPhone made by MediaHub Limited (“we”). It is built so that we don’t need your data: there is no account, no analytics and no advertising, and filtering happens on your device.
Last updated: 7 October 2026
Summary
- We don’t collect, store or sell personal data, and we don’t run servers that receive your browsing or app traffic.
- Safari applies Blockbird’s blocking rules itself. The Safari extensions never see the pages you visit.
- When DNS protection (“Chrome and other apps”) is on, your iPhone’s DNS lookups are filtered on the device and the allowed ones are sent over encrypted DNS to Cloudflare.
- Blocking statistics are stored only on your iPhone.
- Purchases are handled by Apple. We never see your payment details.
Safari content blockers
Blockbird’s Safari extensions are content blockers: they give Safari a list of rules, and Safari applies them by itself. Apple’s design doesn’t let content blockers see which pages you open or what they contain, so Blockbird learns nothing about your browsing in Safari.
DNS protection for Chrome and other apps
Chrome and other browsers on iPhone don’t support extensions, so Blockbird can add a local VPN configuration. iOS calls it a VPN, but it runs entirely on your iPhone and only handles DNS lookups (the step where an app asks for the address of a server name such as example.com). All other internet traffic does not go through it.
- Lookups for domains on Blockbird’s block lists are answered on your iPhone and never leave it.
- Other lookups are forwarded over encrypted DNS (DNS over HTTPS) to Cloudflare’s public resolver 1.1.1.1. If it can’t be reached, Blockbird uses Quad9 (9.9.9.9). If encrypted DNS fails entirely, for example on a restrictive network, Blockbird briefly falls back to regular DNS via Cloudflare (1.1.1.1) or Google Public DNS (8.8.8.8).
- These resolvers receive the domain name being looked up and your IP address, as with any DNS service. Their use of that data is described in their own policies: Cloudflare, Quad9, Google. We don’t receive these lookups.
You can turn DNS protection off at any time in Blockbird or in the iOS Settings app.
Data stored on your iPhone
To show you what was blocked, Blockbird keeps the following only on your device, in storage shared between the app and its extensions:
- counts of blocked and total DNS lookups for recent days;
- the most frequently blocked domains for the current day and a short list of recently blocked domains;
- your settings, including the sites you allowed. When you open Blockbird from Safari’s Share menu, it reads the address of the current page only to show and change the setting for that site.
None of this is sent to us or to anyone else. Deleting Blockbird removes it.
Purchases
Subscriptions are sold and managed by Apple through the App Store. Apple processes your payment and tells the app whether a subscription is active; we never receive your name, Apple Account or payment details. Apple gives developers aggregated, non-identifying sales reports. See Apple’s Privacy Policy.
Notifications
If you allow notifications, Blockbird schedules a reminder on your iPhone before a free trial ends. It is created on the device and not sent through any server.
Filter lists
Blockbird’s filter lists are included in the app and updated with app updates. The app doesn’t contact list providers.
This website
blockbird.app uses no cookies, analytics or third-party scripts. It is hosted by Cloudflare, which processes technical data such as IP addresses to deliver and protect the site.
Children
Blockbird doesn’t collect personal data from anyone, including children.
Your rights
Because we don’t hold personal data about you, there is nothing for us to access, correct or delete. If you have a question about privacy or want to exercise a right under laws such as the GDPR or CCPA, contact us and we’ll help.
Changes
If we change how Blockbird handles data, we’ll update this page and the date above before the change takes effect.
