Vidakuzi ni vifungu vidogo vya maandishi yanayotumwa kwenye kivinjari chako na tovuti unayotembelea. Husaidia tovuti hiyo kukumbuka maelezo kuhusu ulikotembelea, hali inayoweza kurahisisha shughuli ya kutembelea tovuti tena na kufanya tovuti ikufae zaidi. Teknolojia nyingine zinazofanana, ikiwa ni pamoja na vitambulishi mahususi vinavyotumiwa kutambua programu au kifaa, lebo za pikseli na hifadhi ya mfumo, zinaweza kutekeleza jukumu sawa. Vidakuzi na teknolojia nyingine zinazofanana, jinsi zinavyofafanuliwa kote kwenye ukurasa huu zinaweza kutumiwa kwa madhumuni yaliyofafanuliwa hapa chini.

Angalia Sera ya Faragha ili upate maelezo kuhusu jinsi tunavyolinda faragha yako katika utumiaji wetu wa vidakuzi na maelezo mengine.

Utendaji

Cookies and similar technologies used for functionality purposes allow you to access features that are fundamental to a service. These cookies are used in order to deliver and maintain Google services. Things considered fundamental to a service include remembering choices and preferences, like your choice of language; storing information relating to your session, such as the content of a shopping cart; enabling features or performing tasks requested by you; and product optimizations that help maintain and improve that service.

Examples of cookies

Some cookies and similar technologies are used to maintain your preferences. For example, most people who use Google services have a cookie called ‘NID’ or ‘_Secure-ENID’ in their browsers, depending on their cookie choices. These cookies are used to remember your preferences and other information, such as your preferred language, how many results you prefer to have shown on a search results page (for example, 10 or 20), and whether you want to have Google’s SafeSearch filter turned on. Each ‘NID’ cookie expires 6 months from a user’s last use, while the ‘_Secure-ENID’ cookie lasts for 13 months. Cookies called ‘VISITOR_INFO1_LIVE’ and ‘__Secure-YEC’ serve a similar purpose for YouTube and are also used to detect and resolve problems with the service. These cookies last for 6 months and for 13 months, respectively.

Vidakuzi na teknolojia nyingine zinazofanana hutumiwa kudumisha na kuboresha hali yako ya utumiaji katika kipindi mahususi. Kwa mfano, YouTube hutumia kidakuzi cha ‘PREF’ kuhifadhi maelezo kama vile mipangilio ya ukurasa unaopendelea na mapendeleo ya uchezaji kama vile chaguo mahususi za kucheza kiotomatiki, kuchanganya maudhui na ukubwa wa kichezaji. Kwenye YouTube Music, mapendeleo haya yanajumuisha kiwango cha sauti, hali ya kujirudia na kucheza kiotomatiki. Muda wa kidakuzi hiki huisha miezi 8 baada ya mara ya mwisho kutumiwa. Kidakuzi cha ‘pm_sess’ pia husaidia kudumisha kipindi chako cha kivinjari na huduma kwa dakika 30.

Vidakuzi na teknolojia nyingine zinazofanana zinaweza pia kutumiwa kuboresha utendaji wa huduma za Google. Kwa mfano, kidakuzi cha ‘CGIC’ huboresha utoaji wa matokeo ya utafutaji kwa kukamilisha kiotomatiki hoja za utafutaji kulingana na maudhui ambayo mtumiaji aliweka awali. Kidakuzi hiki hudumu kwa miezi 6.

Google hutumia kidakuzi cha ‘SOCS’, ambacho hudumu kwa miezi 13, kuhifadhi hali ya mtumiaji kuhusu chaguo zake za vidakuzi.

Usalama

Google uses cookies and similar technologies for security purposes to protect you as you interact with a service by authenticating users, protecting against spam, fraud and abuse, and tracking outages.

Examples of cookies

The cookies and similar technologies used to authenticate users help ensure that only the actual owner of an account can access that account. For example, cookies called ‘SID’ and ‘HSID’ contain digitally signed and encrypted records of a user’s Google Account ID and most recent sign-in time. The combination of these cookies allows Google to block many types of attack, such as attempts to steal the content of forms submitted in Google services. These cookies last for 2 years.

Baadhi ya vidakuzi na teknolojia nyingine zinazofanana hutumiwa kutambua taka, ulaghai na matumizi mabaya. Kwa mfano, vidakuzi vya ‘pm_sess’ na ‘YSC’ huhakikisha kuwa maombi katika kipindi cha kuvinjari yamefanywa na mtumiaji wala si na tovuti nyingine. Vidakuzi hivi huzuia tovuti hasidi zisichukue hatua kwa niaba ya mtumiaji bila yeye kufahamu. Kidakuzi cha ‘pm_sess’ hudumu kwa dakika 30, na kidakuzi cha ‘YSC’ hudumu kwa kipindi ambacho mtumiaji anavinjari. Vidakuzi vya ‘__Secure-YEC’ na ‘AEC’ hutumiwa kutambua taka, ulaghai na matumizi mabaya ili kusaidia kuhakikisha kuwa watangazaji hawatozwi kimakosa kwa ajili ya maonyesho au shughuli za ulaghai au zisizo sahihi au kwa mitagusano na matangazo; na kuwa watayarishi wa YouTube walio katika Mpango wa Washirika wa YouTube wamelipwa kwa njia ya haki. Kidakuzi cha ‘AEC’ hudumu kwa miezi 6 na kidakuzi cha ‘__Secure-YEC’ hudumu kwa miezi 13.

Baadhi ya vidakuzi na teknolojia nyingine zinazofanana husaidia tovuti na programu kuelewa jinsi wageni wanavyotumia huduma zake. Kwa mfano, Google Analytics hutumia seti ya vidakuzi kukusanya maelezo kwa niaba ya biashara ambazo hutumia huduma ya Google Analytics na kuripoti takwimu za matumizi ya tovuti kwa biashara hizo bila kuwatambulisha wageni mahususi. ‘_ga’, ndicho kidakuzi kikuu kinachotumiwa na Google Analytics na huwezesha huduma kutofautisha mgeni mmoja na mwingine na hudumu kwa miaka 2. Tovuti yoyote inayotekeleza Google Analytics, ikiwa ni pamoja na huduma za Google, hutumia kidakuzi cha ‘_ga’. Kila kidakuzi cha ‘_ga’ ni mahususi kwenye kipengee mahususi, kwa hivyo hakiwezi kutumiwa kumfuatilia mtumiaji au kivinjari fulani kwenye tovuti zisizohusiana.

Huduma za Google pia hutumia vidakuzi vya ‘NID’ na ‘_Secure-ENID’ kwenye huduma ya Tafuta na Google na vidakuzi vya ‘VISITOR_INFO1_LIVE’ na ‘__Secure-YEC’ kwenye YouTube, kwa ajili ya takwimu. Programu za Google za vifaa vya mkononi zinaweza pia kutumia vitambulishi mahususi, kama vile ‘Kitambulisho cha Matumizi ya Google’, kwa ajili ya takwimu.

Kulingana na mipangilio yako ya matangazo, huduma nyingine za Google kama vile YouTube zinaweza pia kutumia vidakuzi na teknolojia hizi na nyingine, kama vile kidakuzi cha ‘VISITOR_INFO1_LIVE’, katika utangazaji.

Baadhi ya vidakuzi na teknolojia nyingine zinazofanana ambazo hutumiwa katika utangazaji ni za watumiaji wanaoingia katika akaunti ili kutumia huduma za Google. Kwa mfano, kidakuzi cha ‘DSID’ hutumiwa kutambua mtumiaji aliyeingia katika akaunti kwenye tovuti zisizo za Google ili kufuata ipasavyo mipangilio ya kuweka mapendeleo ya matangazo anayoona mtumiaji. Kidakuzi cha ‘DSID’ hudumu kwa wiki 2.

Kupitia mfumo wa utangazaji wa Google, biashara zinaweza kutangaza kwenye huduma za Google na pia kwenye tovuti zisizo za Google. Baadhi ya vidakuzi huruhusu Google kuonyesha matangazo kwenye tovuti za wengine na huwekwa kwenye vikoa vya tovuti unazotembelea. Kwa mfano, kidakuzi cha ‘_gads’ huwezesha tovuti kuonyesha matangazo ya Google. Vidakuzi vinavyoanza kwa ‘_gac_’ hutoka kwenye Google Analytics na hutumiwa na watangazaji kupima shughuli za watumiaji na utendaji wa kampeni zao za utangazaji. Vidakuzi vya ‘_gads’ hudumu kwa miezi 13 na vidakuzi vya ‘_gac_’ hudumu kwa siku 90.

Baadhi ya vidakuzi na teknolojia nyingine zinazofanana hutumiwa kupima utendaji wa matangazo na kampeni na asilimia za walioshawishika kutokana na matangazo ya Google kwenye tovuti unayotembelea. Kwa mfano, vidakuzi vinavyoanza kwa ‘_gcl_’ hutumiwa kimsingi kuwasaidia watangazaji kubaini mara ambazo watumiaji wanaobofya matangazo yao hushawishika kuchukua hatua kwenye tovuti yao, kama vile kufanya ununuzi. Vidakuzi vinavyotumiwa kupima asilimia za walioshawishika havitumiwi kuweka mapendeleo kwenye matangazo. Vidakuzi vya ‘_gcl_’ hudumu kwa siku 90. Teknolojia nyingine zinazofanana kama vile Kitambulisho cha Matangazo kwenye vifaa vya Android zinaweza pia kutumiwa kupima utendaji wa tangazo na kampeni. Unaweza kudhibiti mipangilio ya Kitambulisho chako cha Tangazo kwenye kifaa chako cha Android.

Vipengele na maudhui ambayo yamewekewa mapendeleo hujumuisha mambo kama vile matokeo na mapendekezo yanayofaa zaidi, ukurasa wa kwanza wa YouTube uliowekewa mapendeleo na matangazo yanayolenga mambo yanayokuvutia. Kwa mfano, kidakuzi cha ‘VISITOR_INFO1_LIVE’ kinaweza kuruhusu mapendekezo yaliyowekewa mapendeleo kwenye YouTube kulingana na utazamaji na utafutaji wa awali. Na kidakuzi cha ‘NID’ huwezesha vipengele vilivyowekewa mapendeleo vya kukamilisha kiotomatiki katika huduma ya Tafuta unapoandika hoja za utafutaji. Muda wa vidakuzi hivi huisha miezi 6 baada ya mara ya mwisho kutumiwa.

Kidakuzi kingine, ‘UULE’, hutuma taarifa za eneo mahususi kutoka kwenye kivinjari chako kwenda kwenye seva za Google ili Google iweze kukuonyesha matokeo yanayofaa mahali uliko. Matumizi ya kidakuzi hiki yanategemea mipangilio ya kivinjari chako na iwapo umechagua kuwasha mipangilio ya mahali kwenye kivinjari chako. Kidakuzi cha ‘UULE’ hudumu kwa hadi saa 6.

Hata ukikataa vidakuzi na teknolojia nyingine zinazofanana ambazo hutumiwa kuweka mapendeleo, maudhui ambayo hayajawekewa mapendeleo na vipengele unavyoona bado vinaweza kuathiriwa na vigezo vya kimuktadha, kama vile eneo uliko, lugha, aina ya kifaa, au maudhui ambayo unatazama sasa.
