BridgeDream is in development. This notice explains how BridgeDream handles children's data, and it applies from the day a school or family starts using it.
What BridgeDream is
BridgeDream helps children aged 3 to 15 make their own games and stories by describing ideas and building with blocks. AI helpers suggest changes, but the child stays in charge: every change is shown first, and the child decides to keep it, change it or say no ("I'm the captain").
What we collect about your child
- A nickname (not their real name), an avatar picture, their age group (not their date of birth), their class and their language (English or Kiswahili).
- A picture password (three pictures) or secret words. We store them scrambled so that nobody, not even us, can read them.
- The games and projects they make, and what they learn (for example "used a loop").
- What they ask the AI helper, with personal details removed, for 30 days only.
We do not collect real names, dates of birth, home addresses, locations, school uniforms or photos of faces. Children are asked not to type personal details; if they do, the helper explains kindly why we keep them private, and removes them before anything is sent to an AI model.
Where the data is kept
On the child's device, and in our cloud in South Africa (AWS Cape Town), the closest region to East Africa. We do not move children's data to other countries without legal permission.
AI helpers and your child's data
- The helpers are AI, and children are told so: "I am a computer helper, not a person. I can make mistakes, so always check my work!"
- Every request goes through our Safety Gateway first. It removes personal details, checks the request in English, Kiswahili and Sheng, and checks the AI's answer before your child sees it.
- We use AI models from Anthropic, OpenAI, Google and open models through OpenRouter, only under zero data retention terms: the providers do not keep the requests or use them for training. The consent screen lists which providers may receive (cleaned) requests.
- A model can only be switched on after it passes our child-safety tests in English and Kiswahili.
- We never use children's data or projects to train AI models. No adverts, no tracking, no selling of data.
- Young children see "helpers", not brand names. The free Quick helper answers many requests without any AI model at all.
Safety for children
- Games run in a locked box on the screen: they cannot reach the internet or the child's account.
- Shared games are checked for personal details and unsafe content, then approved by a teacher (class sharing) or a parent (family or public sharing). There are no comments and no chat between children; only friendly picture reactions.
- If a child writes something that suggests they may be hurt or in danger, they see a caring message and the free child helpline 116, and the right adult (teacher or parent) is told.
- Teachers can switch the AI off for a class at any time; parents can turn sharing, the Helper Team and voice input on or off, and set time and energy limits.
Consent
Before a child uses AI or sharing, a parent or the school must agree:
- Schools sign a consent agreement that covers their classes.
- Parents confirm with a small M-Pesa charge (for example TZS 200 or KES 10) that is refunded straight away, or with a code sent by SMS to their phone.
Without consent, a child can still build with blocks, but AI helpers and sharing stay off.
Your rights
Parents can at any time:
- see what is held about their child, and download it;
- see what their child asked the AI helper (with personal details removed);
- revoke consent, which switches the account off immediately;
- delete the account and all its data.
Schools can ask us to delete any learner's data. We complete deletion requests within 30 days (most within minutes). Accounts that are not used for 12 months are deleted automatically after we warn the parent or teacher.
The law
We are committed to complying with Tanzania's Personal Data Protection Act, 2022, and with the data protection laws of every country where BridgeDream is offered. We follow Anthropic's guidelines for organisations whose products are used by minors.
Questions or worries
Talk to your child's teacher, or contact us at info@vumbuatechnology.co.tz. If something has gone wrong, we tell the school or parent quickly and, for data breaches, the data protection regulator within 72 hours.
Nani anahusika
BridgeDream imetengenezwa na inaendeshwa na Vumbua Tec Solutions Company Limited, kampuni iliyosajiliwa Tanzania (BRELA Namba 200001885), Nyumba Na. 43, Kiwanja Na. 30, Barabara ya Kanisa la KKT, Mtaa wa Mpakani A, Kijitonyama, S.L.P. 31763, Dar es Salaam, Tanzania. Mawasiliano: info@vumbuatechnology.co.tz.
BridgeDream bado inatengenezwa. Taarifa hii inaeleza jinsi BridgeDream inavyoshughulikia taarifa za watoto, na inatumika kuanzia siku shule au familia inapoanza kuitumia.
BridgeDream ni nini
BridgeDream inawasaidia watoto wa miaka 3 hadi 15 kutengeneza michezo na hadithi zao wenyewe kwa kueleza mawazo yao na kujenga kwa vitalu. Wasaidizi wa AI hupendekeza mabadiliko, lakini mtoto ndiye anayeamua: kila badiliko huonyeshwa kwanza, na mtoto huchagua kulikubali, kulibadilisha au kulikataa ("Mimi ndiye nahodha").
Tunachokusanya kuhusu mtoto wako
- Jina la utani (si jina lake halisi), picha ya avatar, kundi la umri wake (si tarehe yake ya kuzaliwa), darasa lake na lugha yake (Kiingereza au Kiswahili).
- Nenosiri la picha (picha tatu) au maneno ya siri. Tunayahifadhi yakiwa yamefichwa kiasi kwamba hakuna mtu, hata sisi, anayeweza kuyasoma.
- Michezo na miradi anayotengeneza, na anachojifunza (kwa mfano "ametumia kitanzi").
- Anachomwuliza msaidizi wa AI, taarifa binafsi zikiwa zimeondolewa, kwa siku 30 tu.
Hatukusanyi majina halisi, tarehe za kuzaliwa, anwani za nyumbani, mahali alipo, sare za shule wala picha za nyuso. Watoto huombwa wasiandike taarifa zao binafsi; wakiandika, msaidizi anaeleza kwa upole kwa nini tunazilinda, na huziondoa kabla chochote hakijatumwa kwa modeli ya AI.
Taarifa zinahifadhiwa wapi
Kwenye kifaa cha mtoto, na kwenye wingu letu nchini Afrika Kusini (AWS Cape Town), eneo lililo karibu zaidi na Afrika Mashariki. Hatuhamishi taarifa za watoto kwenda nchi nyingine bila ruhusa ya kisheria.
Wasaidizi wa AI na taarifa za mtoto wako
- Wasaidizi ni AI, na watoto huambiwa hivyo: "Mimi ni msaidizi wa kompyuta, si mtu. Naweza kukosea, kwa hiyo kagua kazi yangu kila mara!"
- Kila ombi hupita kwanza kwenye Lango letu la Usalama. Huondoa taarifa binafsi, hukagua ombi kwa Kiingereza, Kiswahili na Sheng, na hukagua jibu la AI kabla mtoto wako hajaliona.
- Tunatumia modeli za AI za Anthropic, OpenAI, Google na modeli huria kupitia OpenRouter, kwa masharti ya kutohifadhi taarifa tu: watoa huduma hawahifadhi maombi wala hawayatumii kufundishia modeli. Ukurasa wa idhini unaorodhesha watoa huduma wanaoweza kupokea maombi (yaliyosafishwa).
- Modeli inaweza kuwashwa tu baada ya kufaulu majaribio yetu ya usalama wa watoto kwa Kiingereza na Kiswahili.
- Hatutumii kamwe taarifa wala miradi ya watoto kufundishia modeli za AI. Hakuna matangazo, hakuna ufuatiliaji, hakuna kuuza taarifa.
- Watoto wadogo huona "wasaidizi", si majina ya makampuni. Msaidizi wa Haraka, ambao ni bure, hujibu maombi mengi bila kutumia modeli yoyote ya AI.
Usalama wa watoto
- Michezo huendeshwa ndani ya kisanduku kilichofungwa kwenye skrini: haiwezi kufikia intaneti wala akaunti ya mtoto.
- Michezo inayoshirikiwa hukaguliwa ili kuondoa taarifa binafsi na maudhui yasiyo salama, kisha huidhinishwa na mwalimu (kushiriki darasani) au mzazi (kushiriki na familia au hadharani). Hakuna maoni wala mazungumzo kati ya watoto; kuna miitikio ya picha tu.
- Mtoto akiandika jambo linaloonyesha kwamba huenda ameumizwa au yuko hatarini, anaona ujumbe wa kumjali pamoja na namba ya bure ya msaada kwa watoto 116, na mtu mzima anayehusika (mwalimu au mzazi) anajulishwa.
- Walimu wanaweza kuzima AI kwa darasa wakati wowote; wazazi wanaweza kuwasha au kuzima kushiriki, Timu ya Wasaidizi na kuongea kwa sauti, na kuweka mipaka ya muda na nishati.
Idhini
Kabla mtoto hajatumia AI au kushiriki, mzazi au shule lazima akubali:
- Shule husaini makubaliano ya idhini yanayohusu madarasa yake.
- Wazazi huthibitisha kwa malipo madogo ya M-Pesa (kwa mfano TZS 200 au KES 10) yanayorudishwa mara moja, au kwa msimbo unaotumwa kwa SMS kwenye simu yao.
Bila idhini, mtoto bado anaweza kujenga kwa vitalu, lakini wasaidizi wa AI na kushiriki hubaki vimezimwa.
Haki zako
Wazazi wanaweza wakati wowote:
- kuona taarifa zinazohifadhiwa kuhusu mtoto wao, na kuzipakua;
- kuona alichomwuliza msaidizi wa AI (taarifa binafsi zikiwa zimeondolewa);
- kuondoa idhini, jambo linalozima akaunti mara moja;
- kufuta akaunti na taarifa zake zote.
Shule zinaweza kutuomba tufute taarifa za mwanafunzi yeyote. Tunakamilisha maombi ya kufuta ndani ya siku 30 (mengi ndani ya dakika chache). Akaunti zisizotumika kwa miezi 12 hufutwa zenyewe baada ya kumwonya mzazi au mwalimu.
Sheria
Tumejitolea kufuata Sheria ya Ulinzi wa Taarifa Binafsi ya Tanzania, 2022, na sheria za ulinzi wa taarifa za kila nchi ambapo BridgeDream inatolewa. Tunafuata miongozo ya Anthropic kwa taasisi ambazo bidhaa zao zinatumiwa na watoto.
Maswali au wasiwasi
Zungumza na mwalimu wa mtoto wako, au wasiliana nasi kupitia info@vumbuatechnology.co.tz. Jambo likienda vibaya, tunaijulisha shule au mzazi haraka na, kwa uvujaji wa taarifa, tunamjulisha mdhibiti wa ulinzi wa taarifa ndani ya saa 72.
