Personal preferences live on the List Settings → General Settings tab. Every one of them affects only you: they change nothing for other users and never touch catalog data.
Interface Language — the language of the site itself (Turkish / English).
Title Language — which language anime titles are written in. Details: the Title Language section on the "Fields and Personal Data" page.
Default List — whether the home page opens on the Full List or My List.
Chronology View — whether chronology markers are listed in release order, story order, or both.
Series Chronology View — which tab the series chronology page opens on (chain order / air date).
Spoiler Guard — whether the synopsis is hidden for anime whose earlier seasons you have not watched.
Adult Content — whether entries marked 18+ are shown.
Interface Language
The site runs in Turkish and English. Members pick the language in List Settings; the choice is saved to your account. When browsing without signing in, use the TR | EN links at the top right of the page. Every page has an English address - the same address with ?lang=en added: share such a link and the other person opens the page in English, while your own saved language stays as it is. The interface language does not change anime titles — that is a separate preference. If a synopsis does not exist in your language, the Turkish original is shown.
Adult Content (18+)
Some catalog entries, and some genre/sentence labels, are marked 18+. This preference is off by default, and while it is off:
18+ anime are not shown in lists, search, recommendations or statistics.
If such an anime's detail page is opened, a neutral notice appears instead of the content.
Genre and sentence labels marked 18+ drop out of the filter lists and off the detail page badges.
Where a series or chronology link points at an 18+ entry, only its title is hidden — the link itself stays.
Turning it on is up to you:
Tick "Show adult content" under List Settings → General Settings and those entries become visible to you. The preference is per person: a moderator who wants to see them turns on their own checkbox too.
Spoiler Guard
For later entries in a series, the synopsis is not shown directly while you have not watched the entries before it. The full rule is in the Spoiler Guard section on the "Series and Episode Info" page. To switch it off: List Settings → General Settings → "Hide the synopsis of seasons I have not watched".
