## What is OneBlock?

OneBlock is an ad blocker for Safari only. It works in Safari and does not work in other browsers such as Chrome or Firefox.

OneBlock does not block YouTube video ads or ads that other apps show on their own. It blocks ads and trackers on web pages you open in Safari.

WHAT IT DOES
OneBlock blocks most ads and trackers in Safari. It combines EasyList and EasyPrivacy, global filter lists, and YousList, a list for Korean sites, with extra rules that OneBlock maintains itself. Banners, pop-ups, and trackers on both Korean and international sites are covered.

HIDE DISTRACTIONS
Five switches let you hide only what you want. All of them are off by default.
- Hide YouTube Shorts
- Hide YouTube comments
- Hide Instagram Reels
- Hide Naver News comments
- Hide cookie consent banners

ALLOW SITES ONE BY ONE
If a site does not look right, or you simply want a site left alone, add it to your allowed list. Tap "Allow in OneBlock" in Safari's share menu to do it in a moment. You can also type a site address in the app.

AUTOMATIC RULE UPDATES
Blocking rules update automatically when you open the app or in the background, without waiting for an app update. The app downloads new rules and applies them in Safari. You can also tap "Update now" in the app. If a site has a problem, use "Report a site problem" in the app; it opens an email. Reports help us improve our rules.

ONE PURCHASE FOR IPHONE, IPAD, AND MAC
No subscription. Buy once and use OneBlock on every iPhone, iPad, and Mac signed in to the same Apple Account.

PRIVACY
OneBlock can't see the sites you visit. Only the names of sites you allow yourself are stored, on your device. OneBlock needs no account, includes no analytics, and collects no personal data. Your allowed sites and switch settings stay on your device. The only network request the app makes is downloading the latest rule files, and that request carries no information that identifies you.

HOW TO GET STARTED
Install OneBlock, then turn it on in Safari. Turn on both OneBlock items (OneBlock Ad Blocking and OneBlock Extra Rules). The app walks you through each step and checks that it is on.
- iPhone and iPad: Settings > Safari > Extensions, then turn on every OneBlock item.
- Mac: Safari > Settings > Extensions, then turn on every OneBlock item.

ADS ONEBLOCK CAN'T BLOCK
- YouTube video ads, the ones that play before or during a video, can't be blocked. They play from the same servers as the videos, so the ads alone can't be singled out.
- Ads that other apps show on their own can't be blocked. OneBlock works by giving rules to Safari, so it doesn't reach outside Safari.
- Apple allows this kind of blocking extension only in Safari. It doesn't work in other browsers such as Chrome or Samsung Internet.
- OneBlock reduces most ads but cannot promise to remove every one. If a site still shows ads, tell us with the report button in the app.

FILTER LIST CREDITS
OneBlock converts the following public filter lists into Safari's content blocker format and adds its own rules.
- EasyList (https://easylist.to), licensed under CC BY-SA 3.0
- EasyPrivacy (https://easylist.to), licensed under CC BY-SA 3.0
- YousList (https://github.com/yous/YousList), licensed under CC BY 4.0
EasyList, EasyPrivacy, and YousList belong to their authors. They are not affiliated with or endorsing OneBlock.
