1. Muhtasari

Unaweza kuomba kufutwa kabisa kwa akaunti yako ya InstruChem na data yako ya kibinafsi. Ukurasa huu unaeleza jinsi ya kuomba, tunachofuta, tunachoweza kubaki, na muda wa kuchakata.

Kufuta akaunti ni hatua isiyoweza kutenduliwa. Utapoteza ufikiaji wa sura ulizonunua isipokuwa usajili tena na ununue upya.

2. Jinsi ya Kuomba Kufutwa

Tuma barua pepe kutoka anwani iliyounganishwa na akaunti yako (au eleza wazi namba ya simu uliyosajili):

Barua pepe: outpublishinghouse@gmail.com
Mada: Ombi la Kufuta Akaunti InstruChem

Jumuisha ujumbe wako:

Jina kamili lililotumika kwenye programu
Namba ya simu iliyosajiliwa
Tamko fupi kwamba unataka akaunti na data yako ya kibinafsi ifutwe

Tunaweza kuwasiliana kupitia simu hiyo kuthibitisha ombi kabla ya kuchakata.

3. Tunachofuta

Baada ya uthibitisho, tunafuta au kutokutambulisha:

Data	Hatua
Wasifu wa akaunti (jina, simu, hash ya PIN)	Inafutwa
Mapendeleo ya kusoma (lugha, mwonekano)	Yanafutwa
Ufikiaji wa sura ulizonunua kwenye akaunti	Unaondolewa
Shughuli za kusoma (mf. kumbukumbu za sura)	Zinafutwa
Vipendwa na kikao ndani ya programu kwenye seva	Vinafutwa
Hati za kuingia (mtumiaji wa Supabase)	Zinafutwa

Data iliyohifadhiwa kwenye kifaa chako pekee inaondolewa unapofuta programu.

4. Tunachoweza Kubaki

Rekodi fulani zinaweza kubaki kama sheria inavyotaka, kuzuia udanganyifu, au kutatua migogoro ya malipo.

Data	Sababu	Muda wa kawaida
Marejeleo ya muamala wa malipo (kiasi, tarehe, namba ya mtoa huduma)	Uhasibu, kodi, na wajibu wa kisheria	Hadi miaka 7 au kama sheria ya Tanzania inavyotaka
Mawasiliano kuhusu ombi lako la kufutwa	Uthibitisho wa ombi na utii	Hadi miaka 2
Takwimu zilizojumlishwa bila kutambulisha	Kuboresha huduma (hazikutambulishi tena)	Bila muda maalum

5. Muda wa Kuchakata

Tunalenga kukamilisha maombi yaliyothibitishwa ndani ya siku 30. Utapokea uthibitisho kwa barua pepe akaunti yako inapofutwa.

6. Mbadala

Kutoka tu: Tumia Mipangilio → Toka bila kufuta data.
Sasisha taarifa: Wasiliana nasi kusahihisha jina au simu badala ya kufuta.
