Mkuu i believe data unazoziongelea zinazoenda kwenye advertisement companies ni data kama age, gender, behaviour etc na hizi sio kwamba wanaziuza kwenye kampuni za matangazo, ila ni developer mwenyewe ndo anachagua, na hii pia ni kwa apps kwenye store zote... I develop apps mkuu, moja ya vitu ukitaka kuweka ads zako mfano kama google ni kutumia Admob, kwenye admob sdk iwe ya android, iOS unachagua mwenyewe what kinda data you want to collect from the person.
Kusema apps kama flashlight zinacollect data kwenye android na sio kwenye other OSs si kweli, A company like google has your data na most times ni sisi ndo tunakubali kugawa data, vitu kama browsing history, anytime you browse huku umelogin kwenye google with your gmail account wao wanakusanya data regardless unatumia safari, chrome au any other browser, facebook the same thing, ukiingia kwenye shopping site yoyote ukasearch a certain laptop, ukirudi facabook utakutana na ads za laptop nyingi tu, ukienda google the same thing, hii haitegemei platform unayotumia, inategemea na either developer anataka kukusanya data flani toka kwako au la.. Hata watengeneza website wenyewe wana scripts za javascript wakitaka kukusanya data wanakusanya na nothing apple nor google nor microsoft can do anything about.
Tunarudi kulekule kua kampuni zote zinakusanya data, the only way to stay free ni kutokutumia all big sites, kuwa na email encrypted, au kuhamia kutumia browsers kama tor vile kuaccess internet, kublock javascript yote, kutokuruhusu app yoyote kuchukua data kama location etc, yani ulimwengu wa hivo unabaki bila app yoyote ile bora kurudi kwenye black n white.
