Privacy Policy

QuizAdda (aapka-domain.com) aapki privacy ko lekar gambhir hai. Ye page saaf-saaf batata hai ki hum kya data lete hain, kyun lete hain, aur uske saath kya karte hain.

1. Hum kya data lete hain

### Teachers se
- Naam, email, phone (optional), institute ka naam
- Password — hamesha encrypted (hashed) roop me, hum use padh nahi sakte
- Google se login karne par: naam, email aur profile picture
- Payment karne par: order ID aur amount (card/UPI ki details hum nahi lete)

### Students se
- Naam aur mobile number — bas itna hi
- Optional profile photo (na dene par ek random emoji mil jaata hai)
- Quiz ke jawab, points aur jawab dene me laga time
- IP address — sirf ek hi device se do baar join rokne ke liye

### Apne aap
- Browser ka type aur basic technical log (security ke liye)

## 2. Ye data kis kaam aata hai
- Quiz chalane, score ginne aur leaderboard banane ke liye
- Winner tay karne aur gift bhejne ke liye
- Teacher ko unki class ka result dikhane ke liye
- Service ko surakshit rakhne aur galat istemaal rokne ke liye
- Aapko service se judi zaroori jaankari bhejne ke liye

Hum aapka data kisi ko bechte nahi hain. Kabhi bhi.

## 3. Mobile number ka khaas dhyan
- Student ka mobile number leaderboard par kabhi nahi dikhta
- Wo sirf usi quiz ke teacher ko dikhta hai
- Gift claim karne par address sirf usi teacher tak jaata hai jisne quiz banaya
- Hum us number par marketing message nahi bhejte

## 4. Cookies
Hum sirf zaroori cookies use karte hain:

- Quiz token — taaki quiz ke beech me page refresh karne par aap bahar na ho jaayein
- Sound on/off jaisi choti settings aapke browser me hi save hoti hain

Koi advertising ya tracking cookie nahi hai.

## 5. Data kitne din rehta hai
- Quiz ka data tab tak rehta hai jab tak teacher us quiz ko delete na kare
- Teacher account delete hone par uske saare quiz, students aur answers bhi delete ho jaate hain

## 6. Suraksha

- Phir bhi, internet par 100% suraksha ka daava koi nahi kar sakta

## 7. Bachchon ka data
Ye platform school aur coaching classes ke liye bana hai. 18 saal se kam umar ke students apne teacher ki dekhrekh me hissa lete hain. Hum bachchon se zaroorat se zyada koi jaankari nahi lete — sirf naam aur mobile number. Agar kisi abhibhavak ko lage ki unke bachche ka data hata dena chahiye, to Contact us se sampark karein, hum jald hata denge.
