Zak Trade Fairs & Exhibitions

Version 1 · last updated 18 October 2026

Privacy policy

This policy explains how Zak Trade Fairs & Exhibitions Pvt. Ltd. ("we", "us") handles personal data in Zak Expo Hub, the sales and bookings system at https://expohub.zakgroup.com that we use to run our trade shows: Zak Glass Technology, Zak Doors & Windows, Zak Aluminium Extrusions and Zak Fenestration India.

We are the Data Fiduciary under India's Digital Personal Data Protection Act, 2023 and the Digital Personal Data Protection Rules, 2025 (together, "DPDP"). For people in the European Union or the United Kingdom we are the controller under the GDPR (see the section near the end).

Who we are and how to reach us

Whose data this covers

What we collect

About you as a business contact

When you use our public pages

On our social media accounts When you comment on our posts, mention one of our show accounts or (where we have switched it on) send it a message, the network gives us your public name or username, what you wrote, when, and a link to it. Our staff may answer you there, link you to a contact we already hold, or add an enquiry from what you wrote. We don't receive your email or phone number this way, and we don't treat a comment as consent to email, call or WhatsApp you. Links in our posts carry campaign tags (for example utm_source=instagram and utm_medium=social), so we can tell which post brought an enquiry.

Email read receipts and link tracking When our sales team sends you an email from Zak Expo Hub, it may contain a tiny image and links that pass through our server. That tells us when the email was opened, which links were clicked, and from what kind of device, so the salesperson can follow up at a sensible time. We store a scrambled (hashed) form of the IP address, not the address itself. If the email is opened on a new device or from a different place than before, the salesperson may see "opened on another device or by someone else", and if someone new from your company joins the conversation, they may see that it was forwarded to them.

You can avoid this by not loading images in your email app; links still work. Apple Mail Privacy Protection and some security scanners open every email automatically: we mark those as "maybe" and don't count them. Our campaign emails (newsletters and show updates) are sent through SendGrid, which records opens, clicks, bounces and unsubscribes in the same way.

About our staff Name, work email, phone and WhatsApp number for notifications, photo, role and shows, the work done in the system, an audit log of changes, sign-ins with the device, browser, IP address and approximate place (looked up with ipapi.co), passkeys (we hold only the public key) and two-factor settings.

Things we don't collect We don't collect card numbers or bank details: online payments go through Razorpay. We don't build advertising profiles, sell personal data or use advertising cookies.

Why we use it and on what basis

What we do Basis under DPDP
Answer your enquiry, send proposals, hold stands, take bookings, raise invoices and collect payments You gave us the data for this purpose (a legitimate use, DPDP section 7(a)), and to perform the booking
Keep records of bookings, invoices and payments Compliance with Indian law (company, tax and GST law)
Send you show news and campaigns by email or WhatsApp Your consent, which you can withdraw at any time
Remind you of payments due and stands on hold The booking you made with us, or your consent where we ask for it
Find and contact companies that may want to exhibit Information you or your company made public (see "Where we get data from")
Keep the system secure, prevent fraud and spam, and keep an audit trail Legitimate uses for our own employees and to protect the data we hold
Staff accounts and sign-in records Employment, a legitimate use under DPDP section 7(i)

We don't use your data for any purpose you wouldn't reasonably expect from a trade show organiser.

Where we get data from

Mostly from you or your company. We also use:

AI

Some features use Google Gemini: preparing a short brief before a meeting, drafting the notes of a Google Meet call from its transcript (only for staff who switched this on), reading a visiting card photo, and (if switched on) answering staff questions about how to use the system. Names, email addresses and phone numbers are removed from text before it is sent, except a visiting card photo, which is sent as the image itself. We use Gemini's paid service, under which Google says it does not use what we send to improve its products. A person always checks what AI produces before it is used.

Once for each new hall plan, Anthropic's Claude reads the hall's blank grid drawing and the layout brief to propose a stand layout. No exhibitor, booking or personal data is sent, and staff edit the result by hand.

How we protect it

Cookies and browser storage

Zak Expo Hub uses only the cookies it needs to work: a session cookie, a "remember me" cookie if a staff member chooses it, and a security cookie that protects forms (CSRF). It stores a few preferences in your browser, such as light or dark mode and remembered filters. The chat on our websites keeps an ID in your browser so a conversation can continue. We use no advertising or tracking cookies.
