Privacy Policy
Last updated October 17, 2026
ChatnBid ("we") runs timed online auctions at chatnbid.com, with bidding also available through our WhatsApp number and our Telegram bot (@Chatnbidbot). This policy explains what we collect, how we collect it, and how we use it. It also serves as the privacy policy for our WhatsApp and Telegram services.
What we collect
- Mobile phone number, collected in one of three ways: you enter it on our website and confirm a one-time code; you message our WhatsApp number (WhatsApp tells us the number you message from); or you tap "Share my number" in our Telegram bot (Telegram sends us your number only when you tap that button). We use it to create your account and log you in.
- Display name, shown publicly next to your bids. If you sign up through WhatsApp or Telegram, we start with the first name and last initial from that app's profile; you can change it.
- Auction activity: lots you list, bids you place, and results.
- Telegram user ID, only if you link a Telegram account, so bid buttons in Telegram groups know it's you.
- WhatsApp messages you send us, such as "BID" requests and button taps, and the time of your last message (WhatsApp only lets us reply freely within 24 hours of it).
- Your alert choices: whether you opted in to alerts by text or WhatsApp, and when.
How we use it
- To run auctions: record bids, enforce the timer and rules, and determine winners.
- When a lot sells, we share the winner's and seller's display names and phone numbers with each other so they can arrange payment and delivery. Your phone number is otherwise never shown publicly.
- To send the messages described below.
We use data received from WhatsApp and Telegram only to provide ChatnBid's bidding and alert features to you. We do not sell it, use it for advertising, or use it to build profiles for any other purpose.
WhatsApp and Telegram messages
When you message us on WhatsApp or tap a ChatnBid button in Telegram, we reply in that chat (lot photos, bid buttons, bid confirmations). We send WhatsApp messages you didn't ask for in that conversation, such as outbid and "you won" alerts, only if you opted in: on our website, on your account page, or by replying START or YES on WhatsApp. Reply STOP on WhatsApp at any time to turn them off. In Telegram, the bot messages you privately only after you start it.
A phone number shared through Telegram is used to create your account and log you in. We send texts or WhatsApp messages to it only if you separately opt in to those alerts.
Text messaging (SMS)
We send one-time login codes, and, only if you opt in, alerts when you are outbid. Parties to a completed sale also receive messages about that sale (the result, checkout, payment, shipping and escrow updates) by WhatsApp if they messaged us in the last 24 hours, by Telegram if linked, or otherwise by text. Message frequency varies. Message and data rates may apply. Reply STOP to opt out of alerts at any time, or HELP for help.
No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text messaging opt-in data and consent are not shared with any third parties, except service providers that deliver our messages (such as our SMS carrier, Twilio).
Service providers
We use Supabase (database and login), Vercel (hosting), Twilio (text messages and WhatsApp delivery), Meta / WhatsApp (WhatsApp messaging) and Telegram (Telegram messaging) to operate the service. Messages you exchange with us on WhatsApp or Telegram are also subject to those apps' own privacy policies.
Retention & deletion
Auction records are kept as a record of sales. To delete your account, email support@chatnbid.com; we delete your profile, phone number, Telegram link and WhatsApp details without undue delay, keeping only anonymized bid history needed for completed sales. You can also unlink Telegram or turn off WhatsApp alerts on your account page at any time.
Age
ChatnBid is for adults 18 and over. We don't knowingly collect data from anyone younger.
