Privacy Policy
Last updated: 14 November 2026
A3 Chat is a customer-messaging inbox made and run by A3 Tech, Chattogram, Bangladesh. A business connects its own Facebook Page, Instagram account, WhatsApp Business number and TikTok business account, and its staff then read and answer their customers' messages and comments in A3 Chat. This policy explains what information the app handles and how.
1. Who is responsible for your information
For messages you send to a business that uses A3 Chat, that business is responsible for your information; A3 Tech stores and processes it only to provide the inbox to that business, following this policy.
2. Information we receive
- Messages you send to a business that uses A3 Chat on Facebook Messenger, Instagram Direct, WhatsApp or TikTok: text, photos, videos, voice messages and files, with the time they were sent.
- Comments you write on that business's Facebook Page posts and Instagram posts, and replies to them.
- Basic profile information that Meta shares with the business you message: your name, username and profile picture, and an ID that identifies you only to that business (for WhatsApp, your phone number and WhatsApp name).
- Information you give in the chat, such as a phone number or delivery address for an order.
- Calls. If you call the business through Messenger or WhatsApp (or it calls you), the time and length of the call. When the business's staff answer or make the call in A3 Chat (on the website or in the A3 Chat phone app), the call is recorded: both voices, kept for 90 days, and only that business's own staff can listen to it.
- From businesses that connect to A3 Chat: the name and ID of the connected Facebook Page, Instagram account and WhatsApp Business account and phone number, the access keys Meta issues for them, and the names and logins of the business's staff.
We do not receive your password, your friends list or anything you have not sent to the business.
2a. The A3 Chat phone app (Android and iPhone)
The business's staff can use the A3 Chat app on their phones. The app shows the same chats as the website and handles only what is needed for that:
- Sign-in: the staff member's email or username and password are sent once to sign in; the phone then keeps a sign-in key in its secure storage. Signing out, or being removed from the business's team, ends that key at once.
- Microphone: only to record a voice message the staff member chooses to send, and during a call they answer or make. During a call the app shows an "On a call" notice and the call screen says it is recorded.
- Camera and photos: only to take or pick a photo or video the staff member chooses to send. The app does not read the phone's photo library by itself.
- Notifications: to alert staff about new messages, the phone gives the app an alert key (from Google Firebase Cloud Messaging on Android, Apple Push Notification service on iPhone), which we keep with the staff member's account.
- Device name (for example "Samsung Galaxy A15"), so a staff member can recognise their signed-in phones, and short call connection reports (connected or not, sound sent and received) to fix call problems.
The app does not read the phone's contacts, location, call log or other apps, does not show ads and has no advertising or tracking code.
3. How we use it
- To let the business answer your questions and comments (prices, sizes, delivery, shop locations).
- To take and deliver your orders, and to help with exchanges and complaints.
- To keep a history of the conversation so any of the business's staff can continue it.
We do not sell your information, we do not use it for advertising, and we never show one business's conversations to another business.
4. AI-assisted replies
A3 Chat can use AI models, currently DeepSeek (and, where a business chooses it, Claude from Anthropic), to help answer messages: it suggests replies that staff check before sending, and, if the business turns this on, it may answer messages directly when staff are away. To do this, the recent messages of the conversation (and a photo you sent, if any) are sent to the AI provider's API to write the reply. The provider processes this data on our behalf under its API terms. We do not send names, phone numbers or addresses to the AI unless they are part of the messages being answered. A message written by the AI is marked as such in the app, and you can always ask to talk to a person.
5. Who we share it with
- Meta (Facebook, Instagram, WhatsApp) — the messages travel through Meta's platforms.
- TikTok — messages to a TikTok business account travel through TikTok's business messaging service.
- The AI provider (DeepSeek, or Anthropic where chosen) — for AI-assisted replies, as described above.
- The business's courier — only your name, phone number and address, when you place an order, to deliver it.
- Google (Firebase Cloud Messaging) and Apple (Push Notification service) — they deliver new-message alerts to the staff's phones; an alert carries the customer's name and the start of the message.
- Our hosting provider (DigitalOcean) — the servers where A3 Chat runs and stores data.
We share information with authorities only when the law requires it. We first check that the request is lawful, challenge it if it is not, give only the minimum information needed, and keep a record of every request and our answer.
6. How long we keep it
We keep conversations and comments for as long as the business needs them to serve you and for its order records, and at most 3 years after your last message, unless you or the business ask us to delete them earlier. When a business disconnects from A3 Chat, we stop receiving its messages and delete its access keys; it can ask us to delete its conversations as well.
7. Security
Only staff with their own login can sign in, and a business's conversations are shown only to its own staff. Access keys to Meta, TikTok and the AI providers are stored encrypted. Data travels over encrypted connections (HTTPS).
8. Your choices and rights
- You can ask what information we hold about you, ask us to correct it, or ask us to delete it — see Data Deletion.
- You can stop messaging a business at any time, and you can block its Page in your Facebook / Instagram settings or block its number in WhatsApp.
- A business can disconnect its accounts from A3 Chat at any time (see Data Deletion).
