We also collect limited technical information automatically, such as IP address, browser type, pages visited, and referral source, via cookies and analytics tools (see Section 5).

We use this information to respond to inquiries and deliver Services, schedule calls, communicate about your project or account, improve our Site and Services, and send marketing communications where permitted, with an option to opt out at any time.

Our Site may use cookies and similar technologies to remember preferences and understand Site usage. You can control cookies through your browser settings.
Third-party links and tools
Our Site may link to or embed third-party tools, for example Calendly, YouTube, or social media. These third parties have their own privacy practices, and we encourage you to review their policies.
Data retention
We retain personal information only as long as necessary for the purposes described in this policy or as required by law.

Your rights
Depending on your location, you may have rights to access, correct, or erase your personal information, to withdraw consent, and to nominate another person to exercise your rights in the event of death or incapacity. If you are in India, these include rights under the Digital Personal Data Protection Act, 2023.
