Privacy policy
Short version: we collect only what we need to buy, ship and deliver your orders — and we never sell it.
What we collect
When you order or message us, we collect what you give us: your name, mobile number, delivery address, and the details of your orders. When you sign in, we send a one-time code (OTP) to your mobile to confirm it is you. We also keep the messages you send to support, and your referral code.
Why we collect it
To buy your products in China, deliver them to you, confirm your payments, tell you where your order is, and answer your questions. Your mobile number is also how we send order updates by SMS. We do not use your details for anything else without telling you first.
What we never do
We never sell your name, mobile number, address or order history to anyone. We never share your details with advertisers. Your order and payment details are visible only to you and to OnVolume support and admin staff who need them to do their job.
Cookies and your device
We use a small cookie to remember your language (English or Bangla) and your cart. The site also records which pages are visited, the city and the device type, so support can help you — never your screen or your exact address.
Your choices
You can ask support to correct your name, mobile number or address, or to delete your account details. Deleting your account does not delete order records we must keep for payment and delivery proof. If you have a question about your data, write to support from the Contact page — support hours are 9am–11pm, every day.
