There’s not a lot of legalese here, because this is a personal blog and I don’t actively collect any information from visitors or make any attempt to track visitors using tracking cookies.
When you post a comment, this blog collects your provided name, e-mail ID, IP address and browser meta-data (private and not shared) along with optional website URL which is publicly displayed with your comment when you post a comment on any of the entries. E-mail ID and IP addresses are simply for the purpose of validating your identity through the Gravatar service (if available) and spam prevention through Askimet by WordPress. Data collected through comments are stored indefinitely on this server.
Even otherwise you are not required to share any personal details at all much less personally identifiable data. Email IDs are kept private and not displayed in the public domain. No email ID is sold or otherwise harvested or shared with third parties (except possibly Gravatar and the WordPress spam prevention tool). If you are still paranoid about this, you may use a throw-away e-mail ID for commenting.
