You may want to take a look at anidb. It doesn’t connect to any third party domains, doesn’t have any ads, has pretty good search system and probably has the most comprehensive database out of all anime tracking sites (full character cast for most series, often with marked episode occurrences, appearing songs and sometimes full staff credits). On the downsides it uses Google reCAPTCHA for registering (not logging in or posting though), doesn’t have a manga database and might require a bit of getting used to.
