A short reference for terms you'll come across throughout these articles.
AdBlock360
The name of our product — always written as one word, with no space.
Note: There is a similarly named ad blocker written with a space ("AdBlock 360"). That product is not ours and is not supported by us. See What Makes AdBlock360 Different.
AdBlock360 app (also: Windows app)
The main application of AdBlock360. It runs on your Windows PC in the background and performs the actual blocking of ads and trackers at the system level. Its main window shows your protection toggle and Protection History.

AdBlock360 Manager (in-page control)
A small control icon the Windows app injects directly onto the web pages you visit, so you can enable or disable ad blocking per site without leaving the page. It works in Chrome, Edge, Firefox, and Opera, and only when AdBlocking is on (and HTTPS Filtering is on for HTTPS pages). Managed under Settings → AdBlock360 Manager. It is part of the Windows app — not a separate browser extension.
Browser Assistant (Browser Extension)
An optional standalone browser extension, available only for Chrome (from the Chrome Web Store). It does not perform blocking itself — it's a control panel in your browser toolbar that communicates with the AdBlock360 app. Distinct from the AdBlock360 Manager above.

AppID (App Identifier)
A unique identifier for your AdBlock360 installation. Support may ask for your AppID when troubleshooting an issue. You can find it under Settings → About.
Basic
The free baseline plan. Ad and tracker blocking work fully; the two Premium features (YouTube Sponsor Skip and App Ad Blocking) are not included.
Premium
The paid plan. Adds exactly two features on top of Basic: YouTube Sponsor Skip and App Ad Blocking.
See Plans Overview.
Trial (Anonymous / Registered)
A free trial of all Premium features. The Anonymous Trial is granted automatically for 7 days on first install (device limit 1). Signing in or registering while it's still active extends it with a Registered Trial — a fresh 7-day base plus a bonus equal to the time remaining on the Anonymous Trial — and raises the device limit from 1 to 3. When the trial ends, you move to Basic.
See Your Free Trial.
Custom Filters
User-managed filter rules and lists, added under Settings → Advanced → Custom Filters — either by uploading a local rule file or by adding a remote list by URL. The built-in filter lists update automatically and are not managed here.
Filter list
A maintained set of rules that determines which content (ads, trackers, unwanted connections) gets blocked. AdBlock360's built-in lists are updated automatically.
HTTPS filtering
The technique that lets AdBlock360 inspect encrypted (HTTPS) traffic for ads and trackers. Without HTTPS filtering, most of today's web could not be filtered. Toggled under Settings → Advanced → HTTPS Filtering.
Learn more in Privacy & Security.
License key
A sequence of letters and numbers (for example XXXX-XXXX-XXXX-XXXX) used to activate AdBlock360 after purchase. You receive it by email after ordering.
Learn more in Entering & Activating Your License Key.
Magic Link
An activation link (starting with adblock360://) included in your purchase email. Clicking it lets the installed app read your license key and activate Premium with no typing.
Verification Required
An error-recovery dialog the app shows when it could not re-establish its secure connection (cryptographic handshake) with our servers — for example after a network outage, a server-side key rotation while the device was offline, or a corrupted local key store. It lets you sign in or enter your license key to recover. If you dismiss it (X), the app moves to Basic and the dialog won't appear again on this device.
Whitelisted Domains (also: Allowlist)
The list of websites where you intentionally disable blocking — for example to support a site, or because a feature would otherwise break. In the v4.2 app this is the Whitelisted Domains page; "allowlist" is the general concept.
Learn more in Disable AdBlocking on a Website.
System-level ad blocking
How AdBlock360 works: ads and trackers are filtered at the operating-system level before they reach any app. Unlike browser-only extensions, AdBlock360 protects your entire device — every browser and every app.
Learn more in System-Level AdBlocking Explained.
Tracker
A script or connection that observes your behavior online — usually to build advertising profiles. AdBlock360 blocks trackers alongside ads.
