Privacy Policy

Last updated: 27 June 2026

1. Introduction

This Privacy Policy explains how CSL Systems (“CSL Systems”, “we”, “us” or “our”) collects, uses, stores and protects information about you when you visit cslsystems.com.bd, place an order, create an account, contact us through WhatsApp, phone, email or any contact form on our website.

CSL Systems is an authorized channel partner in Bangladesh of Hikvision, Dahua, ZKTeco, Virdi and EZVIZ — supplying CCTV cameras, access control systems, biometric attendance devices, IP phones and networking products to homes, offices and enterprises across the country.

By using our website or our services, you agree to the practices described in this policy. If you do not agree, please do not use the site or share information with us.

2. Information We Collect

We only collect the information we actually need to respond to you, fulfil your order or run our business properly. The categories below cover everything we typically handle.

2.1 Information You Give Us Directly

Contact form, WhatsApp and phone inquiries: your name, phone number, email address, company name (if applicable) and the details of your question or project.
Customer account information: if you create an account at checkout or from the My Account page, we store your name, email address, phone number, username and a securely hashed password.
Billing and shipping addresses: house, road, block, area, district, postal code and any delivery instructions you provide.
Order data: the products you purchase, quantities, prices, order date, chosen payment method, invoice number and delivery status.
Payment information: when you pay through bKash, Nagad, Rocket, SSL Wireless, bank transfer or cash on delivery, we receive a transaction reference and the amount. Full card numbers, mobile wallet PINs or banking credentials are never stored on our servers — they are handled directly by the payment gateway.
Comments and product reviews: the name, email and content you submit when leaving a review or a comment on the site.

2.2 Information Collected Automatically

IP address and approximate location
Browser type and version (Chrome, Firefox, Safari, Edge, etc.)
Device type and operating system (mobile, desktop, Android, iOS, Windows)
Pages visited, time spent on each page and the referring website
Date and time of your visit
Cookies and similar technologies (see Section 4)

3. How We Use Your Information

To process and deliver your orders — confirming purchases, arranging courier delivery, issuing invoices and handling returns or warranty claims.
To provide customer support — answering questions you send through the contact form, WhatsApp, phone or email about products, pricing, installation or after-sales service.
To manage your account — letting you log in, view past orders, save addresses and reorder easily.
To send transactional messages — order confirmations, payment receipts, dispatch notifications and warranty information.
For marketing — only with your consent — occasional offers, new product launches and promotions. You can unsubscribe at any time.
To prevent fraud and protect our website — detecting suspicious orders, blocking malicious traffic and keeping the site secure.
To improve our website and product range — understanding which products and pages are most useful to our customers.
To comply with the law — meeting tax, VAT, accounting and other legal obligations under Bangladeshi regulations.

4. Cookies and Tracking Technologies

Like most modern websites, cslsystems.com.bd uses cookies — small text files stored in your browser — to make the site work properly and to understand how it is being used.

Essential cookies: required for the shopping cart, checkout, account login and security. Without these the site cannot function.
Performance and caching cookies: set by LiteSpeed Cache to make pages load faster.
Security cookies: used by Wordfence to identify trusted visitors and block attackers.
Analytics cookies: if Google Analytics or a similar tool is enabled, anonymous statistics help us see which products and pages are most popular.
Third-party cookies: may be set when you click WhatsApp links, embedded YouTube videos or social media buttons.

You can clear or block cookies through your browser settings, but please note that some parts of the site — particularly the cart and checkout — may not work correctly without them.

5. Sharing With Third Parties

We do not sell or rent your personal information. We share data only with the service providers we need to operate our business, and only the minimum information they require.

Payment processors: bKash, Nagad, Rocket, SSL Wireless and partner banks — to process your payments securely.
Courier and delivery partners: Sundarban Courier Service, SA Paribahan, RedX, Pathao Courier and similar providers — to deliver your products. They receive your name, delivery address and phone number only.
Hosting provider: our website and database are hosted with Hosting Bangladesh on servers physically located in Bangladesh.
Website security: Wordfence helps us detect and block malicious traffic.
Analytics: if Google Analytics is enabled, anonymised usage data is processed by Google.
Legal and regulatory authorities: we may disclose information if required by Bangladeshi law, a court order or a lawful request from the National Board of Revenue (NBR), law enforcement or other competent authority.
Brand principals and OEMs: for warranty claims, RMA processing or technical escalation, limited information (such as device serial number and a contact phone number) may be shared with Hikvision, Dahua, ZKTeco, Virdi or EZVIZ service teams.

6. Data Retention

Order and invoice records are retained for at least seven (7) years in line with VAT, income tax and accounting requirements set by the National Board of Revenue (NBR) of Bangladesh.
Customer accounts remain active for as long as you want to keep them. If you ask us to close your account, we will deactivate it and delete or anonymise personal information that is not required for legal or tax purposes.
Contact form and inquiry messages are typically kept for up to two (2) years so we can refer back to past conversations and provide better service.
Server, security and access logs are kept for a limited period for security investigation and troubleshooting.

7. Data Security

We take reasonable technical and organisational steps to protect your information, including:

SSL/HTTPS encryption on every page of the website
Wordfence Web Application Firewall and real-time malware scanning
Strong, hashed passwords — we never see or store your password in plain text
Regular WordPress, plugin and theme updates
Limited staff access on a need-to-know basis
Routine backups stored securely

While we work hard to protect your data, no system connected to the internet can be guaranteed to be 100% secure. Please keep your account password confidential and contact us immediately if you suspect any unauthorised activity.

8. Children’s Privacy

Our products — CCTV, access control, biometric attendance, IP phones and networking equipment — are intended for businesses and adult homeowners. The website and services are not directed at children under the age of 13, and we do not knowingly collect personal information from anyone under 13. If you believe a child has provided us with personal information, please contact us so we can remove it.

9. Your Rights

You have the right to:

Access the personal information we hold about you
Correct any information that is wrong or out of date
Request deletion of your account and personal data (subject to legal record-keeping requirements such as tax invoices)
Opt out of marketing messages at any time
Withdraw consent you previously gave us

To exercise any of these rights, please contact us using the details in Section 13. We will respond within a reasonable timeframe.

10. International Data Transfers

Our website and customer database are hosted on servers located in Bangladesh. However, some of the third-party services we use — such as Google Analytics, certain security tools and email delivery services — may process limited data on servers outside Bangladesh. Where this happens, we rely on those providers’ own security standards and contractual protections.

11. Compliance With Bangladeshi Law

CSL Systems operates in accordance with the laws of Bangladesh, including:

The Digital Security Act, 2018
The Information and Communication Technology (ICT) Act, 2006 (as amended)
Value Added Tax and Supplementary Duty Act, 2012 and related NBR rules on invoice and record retention
The Income Tax Ordinance, 1984 for accounting records
The Consumer Rights Protection Act, 2009

If a future personal data protection law is enacted in Bangladesh, we will update this policy and our practices accordingly.

12. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our services, technology, legal requirements or business practices. When we do, we will revise the “Last updated” date at the top of this page. For significant changes, we may also notify you by email or through a notice on the website. We encourage you to review this page periodically.
