In-depth safety analysis
This extension requests only three API permissions: storage, tabs, and fontSettings. Storage allows it to save your preferences locally. The tabs permission lets it detect when you are on a YouTube tab, and fontSettings enables it to adjust the browser’s font rendering for subtitles. These are minimal and appropriate for a tool that customizes YouTube subtitle appearance; no broad host permissions or data-access capabilities are listed.
As a general browser extension that modifies a specific website’s content, users should be aware that such tools often need to read or alter page elements. Even when permissions appear limited, the extension may use content scripts that interact with YouTube pages. The developer’s Chrome Web Store privacy disclosures state that data is not sold or used for unrelated purposes. Extensions in this category can also become abandoned, but this one shows recent updates.
Our assessment highlights a strong Maintenance & Ownership score, reflecting active upkeep and a recent version release. The weakest dimension is Publisher & Identity, which indicates limited public information about the developer. While this is not unusual for small or independent extensions, users who prioritize transparency may want to research the publisher further before installing.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.

- Publisher 54ac
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
