It seems you're copying your data from myanimelist.net, including the synopsis.

I'm not sure on the details anymore, but I can think this is infringing their copyright.

For https://www.anistats.com/ I chose to display the content from anilist.co and their graphql API. But this was 5 years ago I made this decision.

I don't know if this matters anymore or to you. But congrats for shipping.
