  • Request deletion of your account and associated data.
  • Object to how we process your data.

To exercise any of these rights, email hello@arasu365.in from the address or WhatsApp number linked to your account.

9Children's Privacy

Arasu365 is not directed at children under 13. If we become aware that we have collected data from a child under 13 without parental consent, we will delete that data promptly.
