The extension uses `chrome.storage.sync`, which requires a Chrome profile login to sync settings across devices. However, the blocker works fully offline with local storage, so login is not strictly required for core functionality.

Monetization

The extension contains voluntary donation links (Buy Me a Coffee) but does not gate any features behind a paywall, subscription, or license key. All blocking features are fully available without payment.

Confidence: 95
Payment platform: Buy Me a Coffee
Source: AI / High
Login required: No
Reason: The extension does not implement any login flow, authentication, or account creation. It uses `chrome.storage.sync` to persist settings, which works without explicit login (it uses the browser profile). Core functionality (blocking and hiding NSFW content) operates entirely without requiring any account.
