Is Notion Nice safe?

Low risk

Notion Nice uploads generated Notion images and files to a Tencent COS bucket with embedded credentials.

When its Notion content script creates image, file, or cover assets, it uses embedded Tencent COS credentials to put those objects into the notion-nice-1253546688 bucket. The code configures the ap-nanjing region and CDN base cdn.superai42.com, so generated files tied to Notion space and block IDs are stored outside the browser.
