This policy explains what the AUN Care Bangladesh Android app collects, why, who we share it with, and how you can delete your account. It covers the app only — our website has its own privacy policy.
App package: bd.com.aunprojector.aun_app
The AUN Care Bangladesh app is published and operated by স্মার্ট লিভিং বাংলাদেশ, the company behind the AUN projector brand in Bangladesh. In this policy, “we”, “us” and “our” mean Smart Living Bangladesh.
We are the data controller for the information described here. The app’s data is stored on our own servers (aun-projector.com.bd) and our own business systems.
The short version. The detail is further down.
You sign in with your phone number and a one-time SMS code. There is no password to remember or leak.
No advertising, no advertising ID, no location access, and no third-party analytics SDK — we count how features are used on our own server, not through Google Analytics. We never sell your data.
Settings → Delete my account, right inside the app. See exactly what happens.
We only collect what the app actually needs to do its job. Nothing below is optional-but-secretly-required, and nothing is collected in the background.
| What | When | Why |
|---|---|---|
| Mobile number | When you sign in | It is your account. We send a one-time code by SMS to verify it, and we use it to find purchases and warranty records registered to you. |
| Name, email address, profile photo | If you enter them | To address you properly and to attach your name to warranty paperwork and support tickets. Email and photo are optional; you may use an emoji instead of a photo. |
| Projector details — serial number, model, purchase date, invoice number, dealer name, warranty dates | When you add a projector, or automatically from our sales records matching your number | To show your warranty, and to give you firmware, manuals and guides for your exact model. |
| Photos you choose to upload — invoice photo, spare-part condition photos, repair photos, support-ticket attachments, bug-report screenshots | Only when you attach them | To verify a warranty registration and to let our service team see the problem before your projector arrives. |
| Service and support content — what you write in a ticket or repair request, and the pickup/delivery address you give | When you contact us or book a service | To answer you, collect and return your projector, and deliver spare parts. |
| Order and payment records — what you ordered, the amount, and whether it was paid | If you pay for spare parts online | To fulfil the order, issue a receipt, and handle any refund. We never see or store your card, bKash or Nagad details — those are entered on the payment provider’s own secure page, not in our app. |
| Notification token and your language choice | If you allow notifications | To send you the alerts you asked for, in Bangla or English. Nothing else uses it. |
| App version and a device name | While you are signed in | So you can tell your own sessions apart, so support can reproduce a problem, and so we can offer you an update. |
| How the app’s features are used — for example that the projector finder was opened, or that a price quote was answered | While you use the app | So we can tell which parts of the app are worth improving. These are counts and categories only — the name of a screen or button, and a number. Your phone number, name, address, projector serial and request references are never included, and there is no advertising ID or device fingerprint. If you are signed in, a count is linked to your account number only so that forty visits by one person can be told apart from forty people; we do not build a profile of you. This is stored on our own server, is not shared with anyone, and is deleted automatically after 180 days. |
| Crash reports — where in our code the app failed, your phone model, its Android version and free memory | Only if the app closes unexpectedly | So we can find and fix the fault. Without this, an app that fails on your phone tells us nothing at all and the problem is never fixed. It contains no phone number, no name, and nothing you typed. This is the one part handled by an outside service — Google Firebase Crashlytics (see section 3). |
We never sell your personal information, and we never share it for advertising. We share the minimum necessary with these service providers:
| Provider | What they receive | Why |
|---|---|---|
| Alpha SMS (sms.net.bd, Bangladesh) | Your mobile number and the message text | To deliver your one-time login code and service update SMS. |
| Google Firebase Cloud Messaging | Your notification token and the notification text | To deliver push notifications to your phone. Only if you turn notifications on. |
| Google Firebase Crashlytics | Automatic crash reports only — the technical details of a failure, your phone model and Android version. No phone number, no name, nothing you typed. | So we can find and fix faults that make the app close unexpectedly. Google acts as our processor and does not use this to identify you. Your usage counts are NOT sent here — they stay on our own server. |
| SSLCommerz (Bangladesh) | The amount, an order reference, and the name and number you give at checkout | To take an online payment for spare parts. You enter card, bKash or Nagad details on their secure page — we never receive or store them. |
| Courier companies — such as Pathao, Steadfast or Sundarban | The delivery name, address and phone number for a parcel | To deliver spare parts to you, or return your projector after a repair. Only when something is actually being sent. |
| Our own systems — website, support desk and business software, all operated by us | Everything described in section 1 | These are ours, not a third party’s product. Your data stays inside our systems. |
| Our hosting provider | Stores our databases and files | To run the service. They do not use your data for their own purposes. |
The “what to watch” film suggestions come from The Movie Database (TMDB), and video guides play from YouTube. Film suggestions are fetched by our server, not your phone — TMDB receives nothing about you. Playing a video is a normal YouTube view and is subject to Google’s privacy policy. We may also disclose information if the law requires it, or to protect our rights and the safety of our customers.
All traffic between the app and our servers uses HTTPS. One-time codes are stored hashed, never in readable form, and are rate-limited against guessing. Sign-in tokens are stored hashed, are tied to the phone that signed in, expire after 180 days, and are destroyed the moment you log out or delete your account. Online payments are handled on the payment provider’s own secure page, so card details never reach us. Access to customer data inside our systems is limited to staff who need it for support, service and warranty work. No system is perfectly secure, but we take this seriously and fix problems quickly when they are reported.
The app is intended for customers who own an AUN projector — that is, adults making a purchase. It is not directed at children, and we do not knowingly collect personal information from children. If you believe a child has given us personal information, contact us and we will delete it.
Our servers and service providers may be located outside Bangladesh. Wherever your data is processed, this policy applies to it and we require our providers to protect it.
If we change how the app handles your information, we will update this page and change the date at the bottom. If a change is significant, we will tell you in the app.
Reach a real person on any of these. We reply in Bangla or English.
Smart Living Bangladesh — operator of the AUN projector brand.
