About JustAnime Sync
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.
Nothing about what you watch leaves your browser until you connect an
account. Before that, the extension only fetches the site list and
sends an anonymous installation ping — a random id, the version and the
browser name — so we can count active installs.
The only server it talks to is justanime.me.
