How we handle your data.

Last updated: 19 September 2026

1. Who we are

Microplex Corporation ("Microplex", "we", "us") is a software company headquartered at Udaya Mawatha, Anuradhapura, Sri Lanka, with a branch office in Atsugi, Kanagawa Prefecture, Japan. We build business software, including ERP, POS, financial technology, AI/ML systems, and our SMS and Email Gateway products. This policy covers microplex.lk and the services described below.

2. Information we collect

2.1 Website visitors and inquiries

When you submit the Contact form or an "Integration" inquiry, we collect your email address and the service you asked about, so we can respond to you and follow up.

2.2 Client accounts

If your business becomes a Microplex client (for our Business Systems, SMS Gateway, or Email Gateway solutions), we hold your company name, address, contact email, mobile number, and website, plus your gateway credit balance and API key, in order to provide and bill for the service.

2.3 SMS and Email Gateway traffic

When a client sends a message through our SMS or Email Gateway API, we process the recipient's phone number or email address, sender name, and message content strictly to deliver that message on the client's behalf, and we keep a delivery log (recipient, subject/sender, status, timestamp) for balance tracking and troubleshooting. We act as a data processor for this traffic — it belongs to our client and their end customer, not to us.

2.4 Staff accounts

Our own admin dashboard accounts (used only by Microplex staff) store an email address, phone number, and a securely hashed password.

2.5 Technical data

Like most websites, our hosting infrastructure logs standard technical data such as IP address and request timestamps for security and reliability purposes.

3. How we use this information

• To respond to inquiries and provide the products and support you request.
• To operate the SMS and Email Gateway on behalf of our clients, including credit tracking and delivery logging.
• To secure our systems and administer staff access to the dashboard.
• To meet legal and accounting obligations.

We do not sell your data, and we do not use gateway message content for advertising or profiling.

4. Who we share it with

We use trusted third-party providers strictly to deliver our services:

• Brevo — delivers transactional email on our behalf, for both this website's own emails and our Email Gateway product.
• text.lk — delivers SMS messages sent through our SMS Gateway product.

These providers only receive the minimum data needed to deliver a specific message. We do not share your information with anyone else, except where required by law.

5. Data retention

We keep inquiry and client account data for as long as the relationship is active and as needed for legitimate business or legal purposes. Gateway delivery logs are retained to support balance disputes and troubleshooting, and are periodically reviewed.

6. Security

All traffic to this site and our APIs is encrypted over HTTPS. Staff passwords are hashed using ASP.NET Core Identity and are never stored in plain text. Access to client data and the admin dashboard is restricted to authorized Microplex staff.

7. Cookies

We use a single essential cookie ("Microplex.Admin") to keep administrators signed in to the dashboard. We do not use third-party advertising or tracking cookies on this site.

8. Your rights

You can ask us to access, correct, or delete the personal data we hold about you by contacting us at info@microplex.lk. We'll respond as promptly as we can.

9. Children's privacy

Our services are intended for businesses and are not directed at children. We do not knowingly collect personal data from children.

10. Changes to this policy

We may update this policy as our services evolve. Material changes will be reflected on this page with an updated "Last updated" date.
