Privacy Policy

Last Updated: October 2026

What changed: We added a section on advertising choices for visitors in Europe, the UK, Switzerland and US states (section 6). Our courses now offer an optional account (Sign in with Google, or with an email address and password) so learners can track and keep their lesson progress across devices. See “Optional course account” in section 2 and the new items in sections 4 and 6. Reading every course is still free and needs no account.

1. Who We Are

ABCL TECH ("we," "our," or "us") is a Bangla-first technology media and education platform. We publish free news, editorials, and courses, and we run a small consulting practice. This page explains what data we collect when you visit the site or use our services, and how we handle it.

By using our website, you agree to the practices described below.

2. What We Collect

Information you give us

When you contact us through the form on the Contact page, request a quote, or email us directly, we collect what you choose to share — typically your name, email address, and the contents of your message.

Optional course account (Google or email & password)

You never need an account to read our courses. Tracking which lessons you have finished needs an account. If you sign in with Google, Google shares your name, email address and profile picture link with us. If you create an account with an email address and password, you give us your name and email address; your password is handled by Google Firebase Authentication, stored only in hashed form, and never visible to us. We may send that address a one-time verification email and, when you ask for it, a password-reset email — nothing else. We store your name, email address and your course progress (which lessons you marked as read) so you can continue on any device. We never see or store your Google password or your account password. This data is stored in Google Firebase (Authentication and Cloud Firestore).

Information collected automatically

Like most websites, when you visit ABCL TECH our hosting and analytics tools record some technical data:

• Log & usage data: IP address, browser, operating system, pages viewed, timestamps, and the referring URL.
• Lesson progress on your device: When you are signed in and mark a lesson as read, a copy is kept in your browser (local storage) so pages load instantly, and it is synced to your account. Text-size choices are saved only in your browser.
• Cookies & analytics: We use Google Analytics and Google AdSense, which set cookies to measure traffic and serve ads. You can disable these via your browser settings or opt out at Google's opt-out tool.

3. How We Use It

• Run, maintain, and improve the website and the courses.
• Reply to your contact form messages, course questions, and consulting inquiries.
• Understand which articles and lectures are useful, so we can publish more of what readers actually want.
• Serve relevant advertising via Google AdSense to keep the platform free to read.
• Detect abuse, fraud, or attempts to disrupt the site.

We do not sell your personal data to anyone. Ever.

4. Who We Share With

• Service providers — hosting, analytics (Google Analytics), advertising (Google AdSense), contact-form delivery (e.g. Formspree), and sign-in and progress storage for the optional course account (Google Firebase). They process data on our behalf under their own privacy terms.
• Legal obligations — if required by law, court order, or to protect the rights, property, or safety of ABCL TECH, our readers, or the public.

5. Security

We use reasonable technical and organisational measures to protect the data we hold. However, no internet transmission or storage system is 100% secure, and we cannot guarantee absolute security.

6. Your Rights

You can ask us to access, correct, or delete the personal information you have shared with us. To make a request, contact us via the Contact page and we'll respond within a reasonable timeframe.

Course account: you can sign out at any time from any lesson page; signing out also removes your lesson progress from that device. To delete your course account data (name, email and progress) completely, send us a request through the Contact page using the same email address, and we will delete it.

Exams and certificates: if you take a module test or final exam while signed in, we save your score, the number of questions and the time taken in your account so you can see them on your dashboard. If you request a course-completion certificate, we create a public certificate record containing the name on your profile, the course, your final-exam score and the date; anyone with the certificate link can view it, which is how employers or others can verify it. You can ask us to delete a certificate or your exam history via the Contact page.

Advertising choices (Europe, UK, Switzerland and US states)

Europe, the UK and Switzerland: visitors from these regions see a consent message from Google (a Google-certified consent management platform) before personalised ads or advertising cookies are used. You can choose Consent, Do not consent or Manage options. If you do not consent, you may still see non-personalised ads. You can change or withdraw your choice at any time using the Privacy and cookie settings link that appears on the page.

United States: if you are in a US state with a consumer privacy law (for example California, Virginia or Colorado), you have the right to opt out of the “sale” or “sharing” of your personal information for targeted advertising. Use the Do Not Sell or Share My Personal Information link shown at the bottom of the page. We do not sell personal information for money; the opt-out covers the data Google and its advertising partners may use to personalise ads.

Everyone: you can control personalised Google ads at Google Ad Settings, learn how Google uses data at How Google uses information from sites that use its services, and block or delete cookies in your browser settings.

7. Children

ABCL TECH is not directed at children under the age of 13. We do not knowingly collect personal data from children under 13; if we learn that we have, we will delete it.

8. Changes

If we update this policy, the new version will be posted on this page along with a refreshed "Last Updated" date. Material changes will be highlighted near the top.
