Is it safe or legal to download comics using the Tachiyomi ReadComicsOnline extension?

Tachiyomi itself is a legal, open-source application that acts as a reader. However, the legality of downloading content via the ReadComicsOnline extension depends entirely on the copyright status of the comics and the distribution rights of the source website. Many comics hosted on ReadComicsOnline may be copyrighted and distributed without explicit permission from the creators, making their download potentially illegal in many jurisdictions. Regarding safety, while Tachiyomi is secure, the content sources are third-party, so users should exercise caution. Always ensure you download extensions only from trusted sources within the Tachiyomi app or its official GitHub to avoid modified or malicious versions.
