Privacy, in plain language.

What this policy covers

This policy explains how Tantra AI Labs handles information on tantra-ai-labs.com and its subpages: the contact form and the ordinary server logs every website keeps. It does not cover the Astra AI Gateway (api.modelrouter.in) or third-party sites we link to.

The lab is run by Aditya Wakharkar, based in Nanded, Maharashtra, India. For anything in this policy, that is the data controller.

What we collect

There are only three sources of data on this site.

• Contact form. The name, email address, optional phone number, optional subject and message you submit, plus the IP address and browser user-agent of the request. The last two exist for abuse prevention, not for profiling.
• Server logs. Standard request logs (IP address, timestamp, path, response code, user-agent) kept for security, debugging and capacity planning.
• Theme preference. Your light or dark choice is stored in your browser under the key tantra-theme. It never reaches the server.

There is no analytics product, no advertising pixel, no session recording and no cross-site tracker on this site.

Why we use it

• To reply to you. Your name, email and message are used to answer your enquiry. That is the main reason the form exists.
• To keep the form usable. IP and user-agent help the server filter automated spam.
• To keep the site up. Logs help diagnose failures and detect abusive traffic.

We do not use your data for advertising, profiling, automated decision-making, or model training.

Cookies and local storage

This site sets no tracking cookies. The only thing stored in your browser is the theme preference described above, in localStorage.

Where it lives

Contact messages are stored in a database on a server the lab operates, with access restricted to the founder. The server is rented from a hosting provider, so data is processed on infrastructure we control but do not physically own.

When a message arrives, a notification containing your name, email, subject and message is sent to the founder's phone through Telegram, a third-party messaging service. That means message content is also processed by Telegram under its own privacy terms. If you would rather avoid that, say so in the message and it can be handled by email instead.

Sharing

We do not sell, rent or trade personal data. It is shared only with:

• the hosting provider that runs the server, as a technical necessity;
• Telegram, for the new-message notification described above;
• authorities, if a valid legal request requires it, or where necessary to protect the site and its users from an attack.

Some of these providers may process data outside India. Where that happens, it is limited to what the service needs to function.

How long it is kept

Contact messages are kept while the conversation is active, then archived for reference. They are deleted when you ask, or when they are no longer needed. Server logs rotate on a short cycle and are not kept indefinitely.

Deleting a message removes it from the inbox and the underlying file on disk. Backups, if any exist at that moment, age out on their own schedule.

Your choices and rights

You can ask us to:

• tell you what we hold about you;
• correct something that is wrong;
• delete your message and contact details;
• stop using your data for a particular purpose.

Email adityawakharkar99@gmail.com from the address you used, or send another message through the contact form. Requests are handled by a human, usually within a week. If you are in the EU or UK, this covers your rights under the GDPR; if you are in India, it covers the DPDP Act, 2023. You can also complain to your local data-protection authority.

Children

This site is aimed at people working on software, models and infrastructure. It is not directed at children under 13, and we do not knowingly collect their data. If a child has sent a message, contact us and it will be deleted.

Security

Traffic is served over HTTPS and access to stored data is restricted. No system is perfect, so this is a description of the controls, not a guarantee.

If you find a security issue, please report it through the contact form before disclosing it publicly. Good-faith reports are welcome and will not be treated as an attack.

Changes to this policy

If the way this site handles data changes, this page changes with it and the date at the top moves. Material changes will be noted on the page rather than announced silently.
