JustAnime Sync geliştiren: umutxyp

JustAnime Sync keeps your anime and manga list up to date without you
touching it.

Watch or read like you normally do. When you're far enough into an
episode or chapter, the extension marks it on your JustAnime account —
and on any AniList or MyAnimeList account you've linked there.

• Works on 200+ streaming and reading sites, from Netflix and
  Crunchyroll to MANGA Plus and VIZ
• Every site has its own switch, and one switch pauses all of them
• New sites arrive from the server, so you never wait for an update
• Wrong title? Fix it from the page, and that page is never guessed again
• Stopped halfway? It remembers where, so you can pick it back up
• Add your own Plex, Jellyfin, Emby, Komga or Kavita — that address
  stays in your browser and is never sent to us

Privacy. On a supported site the extension reads the page title, the
address, how far along you are, and — where a site needs it — the text of
the specific elements its rule points at. No other page content, no
cookies, no browsing history. The only server it talks to is
justanime.me.
