Privacy Policy
Last updated: 27 October 2026
In short: we collect only what we need to reply to you and to run our services. We never sell your data. You can ask us to see, correct or delete it at any time by writing to hello@nexsevai.com, or reply STOP on WhatsApp.
1. Who we are
NexSevai Technologies ("NexSevai", "we", "us") is an AI services business based in Vellore, Tamil Nadu, India. This policy explains how we handle personal data on nexsevai.com, in our website chat and on our WhatsApp number. We follow India's Digital Personal Data Protection Act, 2023.
2. What we collect
- When you ask us to contact you (website chat or WhatsApp): your name, business type, area or city, what you need, your preferred time for a call, and your WhatsApp number.
- Your messages to our assistant and its replies, so it can keep track of the conversation and so a person from our team can read the chat and reply to you if you need help.
- If you try the clinic demo: the name you type for the sample booking. The demo clinic is not real.
- On the website: the chat stores a random visitor ID in your browser so the conversation can continue. We do not use advertising or tracking cookies. Fonts are loaded from Google Fonts, which receives your IP address.
3. Why we use it
- To reply to you (by our assistant, or by a person from our team) and to call you about NexSevai's services, at the time you chose.
- To show you a demo you asked for.
- To keep our services working and secure (for example, stopping spam).
We contact you only after you choose a call time in our chat, which is when you agree to be contacted. We never sell or rent your data, and we do not use it for advertising.
4. Who processes it for us
- Google Cloud hosts our assistant and its database (servers in the United States).
- Meta (WhatsApp Business Platform) carries WhatsApp messages between you and us.
- If we turn on AI answers, your messages are processed by Microsoft Azure OpenAI Service to understand them.
These providers process data on our behalf under their own security and privacy terms.
5. How long we keep it
- Chat progress (which question you were on) is deleted 24 hours after your last message.
- Chat messages are deleted after 30 days.
- Contact requests are kept while we discuss our services with you, and deleted when you ask us to.
- Database backups are kept for 30 days and then deleted automatically.
6. Your rights
You can ask us to tell you what data we hold about you, correct it, delete it, or stop contacting you. Reply STOP on WhatsApp and we will not message you again. For anything else, write to hello@nexsevai.com. If you are not happy with our answer, you may complain to the Data Protection Board of India.
7. Our clinic and business customers
When a clinic or business uses NexSevai Desk, the messages their own customers or patients send are handled on that business's behalf and on its instructions. The business decides how that data is used, and should tell its customers in its own privacy notice. We use that data only to run the service for them. NexSevai Desk does not give medical advice.
8. Security
Our assistant runs over encrypted HTTPS connections, access to data is limited to the people who need it, and backups are stored in a private cloud storage bucket.
9. Children
Our services are meant for businesses and adults. Please do not use our chat if you are under 18.
10. Changes and contact
If we change this policy, we will update the date at the top. Questions or complaints: hello@nexsevai.com, NexSevai Technologies, Vellore, Tamil Nadu, India.
