1. Information the app collects
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). |
2. What the app does not collect
- No location. The app never requests or reads your location. Weather shown on the home screen is for Dhaka generally, worked out on our server — your phone is never asked where it is.
- No contacts, no call logs, no SMS reading. When Android auto-fills your one-time code, it hands the app only that single message, using Google’s SMS Retriever. We cannot read your other messages.
- No advertising, no advertising ID, and no third-party analytics or tracking SDK. We do not use Google Analytics or anything like it. The counts described above are recorded on our own server and are never shared. The only outside service the app reports to is crash reporting, described in section 3.
- No card details. If you pay online, the card, bKash or Nagad details are entered on the payment provider’s own secure page. They never pass through our app or our servers, and we never store them.
- Camera pictures are not taken behind your back. The camera is used for three things: scanning the barcode on your projector box, previewing how big the picture will be on your wall, and taking a photo you choose to attach. Barcode scanning and the wall preview are processed live on your phone and never uploaded or saved. A photo is only uploaded when you deliberately attach it to a request.
3. Who else sees your information
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.
4. How long we keep it
- Your app profile and sign-in — until you delete your account. A sign-in session expires by itself after 180 days.
- One-time codes — a few minutes, and they are stored hashed, never as plain numbers.
- Feature usage counts — deleted automatically after 180 days, and erased immediately if you delete your account.
- Crash reports — kept by Google Crashlytics under their retention policy, normally around 90 days.
- Warranty registrations and sales records — kept for as long as the warranty and our accounting obligations require, because they are your proof of purchase and our transaction record. These survive account deletion (see section 5).
- Order and payment records — kept as required by accounting and tax rules, and so a refund can be traced.
- Repair and spare-parts records — kept as service history; after account deletion they are detached from your account.
- Support tickets — kept in our support system as a record of the conversation.
5. Your choices and your rights
- See and correct your information — your profile is editable in the app at any time (tap your photo on the home screen, or Settings).
- Delete your account and personal data — in the app: Settings → Delete my account. Full details, including exactly what is deleted and what we must keep, are on our Delete your account page. You can also ask us to do it for you.
- Ask us to stop counting your usage — email or message us and we will switch it off. Deleting your account also erases everything already counted for it.
- Turn notifications off — in the app, or in your phone’s Android settings. Nothing else stops working.
- Remove a projector — remove it in My Devices; we remember the choice so it is not added back automatically.
- Ask us a question or complain — use any contact route below. We answer in Bangla or English.
6. How we protect it
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.
7. Children
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.
8. Where your data is stored
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.
9. Changes to this policy
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.
