Common Questions About Our Terms and Conditions

Below are the questions we receive most often about how these terms work, what your rights are, and how to act on them through your sigmaexch account.

Yes. Completing account registration on sigmaexch.org means you have read and accepted these terms in full. They remain binding for the entire duration your account is active, including any dormancy periods.

We will send a notification to your registered email at least seven days before material changes take effect. Continuing to use the platform after the effective date counts as acceptance of the updated terms.

Access depends entirely on the laws that apply to you in your location. Where local law does not permit use of this service, you should not register or continue using the account. We may geo-restrict access in such regions.

All payment activity — including deposits via UPI, Paytm and PhonePe — is governed by these terms. Disputes over unprocessed transactions should be raised with our support team along with the reference number from your payment app.

We will notify you by email stating the reason for suspension where legally permitted. You may submit a formal objection through the complaints form in your dashboard, and our compliance team will respond within five business days.

Submit a data request through the Account Settings page or email our support team with the subject line 'Data Request'. We will compile and send your account and transaction summary within 10 business days of verifying your identity.

These terms are governed by applicable Indian law to the extent permitted in your jurisdiction. Disputes follow our internal complaints process first; unresolved matters may then be referred to the relevant legal forum in India.
