Privacy policy

Last updated: 10 November 2026

This policy explains how SINTALIGHT CORP ("we", "us") handles personal information, including information processed through the WhatsApp Business Platform on behalf of our business clients.

Who we are

SINTALIGHT CORP. Contact: sruly@sintalight.com · +1 (917) 819-5844.

What we do with information

We build and run messaging systems for businesses (our "clients"). When a person contacts one of our clients — by WhatsApp message, through a website form, or by email — our systems receive that inquiry on the client's behalf in order to:

• record it as a new inquiry in the client's customer-management system (CRM);
• send the person an automatic reply on the client's behalf (for example, "thank you, we'll be in touch");
• keep a record so that the same person isn't entered twice and nothing gets lost.

For these inquiries our client decides why the information is used; we process it only on their instructions.

Information we process

• Name, phone number and email address, as given by the person or shown in their WhatsApp profile or email;
• the content of their message or form, and which link or campaign it came from;
• dates and times, and the status of the inquiry.

We do not sell personal information, use it for advertising, or use it for any purpose other than providing the service to our client.

Who we share it with

• The client the person contacted, through their CRM;
• service providers that run the system: Meta (WhatsApp Business Platform), Cloudflare (hosting and storage), our email delivery provider, and Google (email handling);
• authorities, only where the law requires it.

How long we keep it

We keep inquiry records only as long as needed to provide the service to our client. We delete them when the client asks, when our service for that client ends, or when the person asks us to (see below).

Your choices and rights

You can ask us to see, correct or delete information about you by writing to sruly@sintalight.com. You can also stop messages from a business at any time by blocking it in WhatsApp or replying "stop". For details on deletion, see our data deletion page.

Security

Information is sent over encrypted connections and stored with access limited to the people who run the service.

Changes

If we change this policy, we will update the date at the top of this page.
