  • Consent: For example, when you register an account, submit a contact form, or opt in to receive emails, you provide clear, informed, and affirmative consent for that specific purpose, consistent with Section 6 of the DPDP Act.
  • Legitimate interest: For example, to maintain Forum security, prevent fraud and spam, and improve our services, where this does not override your fundamental rights.
  • Legal obligation: Where processing is necessary to comply with applicable law, regulation, or a valid legal request from a competent authority.
  • Contractual necessity: Where processing is necessary to provide the Forum services you have requested, such as your account and posting functionality.

You have the right to withdraw consent at any time where processing is based on consent, without affecting the lawfulness of processing carried out before such withdrawal.

5. Sharing and Disclosure of Information

We do not sell your personal data. We may share information in the following circumstances:

  • Publicly visible content: Your username, avatar, bio, and any topics/replies you post are publicly visible to other visitors and members by the nature of a public discussion forum. Please do not post sensitive personal information in public posts.
  • Service providers: We share data with trusted third-party vendors who perform services on our behalf, including web hosting, the wpForo forum software, email delivery (e.g., SMTP providers), spam protection (Akismet), security services (e.g., Wordfence), caching/performance services (e.g., LiteSpeed Cache), and analytics providers (e.g., Google Analytics).
  • Advertising partners: We may work with advertising networks (such as Google AdSense) that may use cookies and similar technologies to serve relevant ads and measure their performance. These partners may collect information about your visits to this and other websites.
  • Legal requirements: We may disclose information if required to do so by law, regulation, legal process, or governmental request, or to protect the rights, property, or safety of ourselves, our users, or the public.
  • Business transfers: If we are involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction, subject to this Policy or a policy at least as protective.

6. Cookies and Tracking Technologies

We use cookies and similar tracking technologies to operate and improve the Forum. Categories of cookies used include:

  • Strictly necessary cookies: required for login sessions, security, and core Forum functionality. These cannot be disabled without affecting site functionality.
  • Performance and analytics cookies: help us understand how visitors use the Forum (e.g., Google Analytics) so we can improve content and structure.
  • Advertising cookies: used by third-party advertising networks to deliver relevant ads and limit repeated ad display.
  • Preference cookies: remember your settings, such as theme or display preferences.

You can control or delete cookies through your browser settings. Disabling cookies may affect your ability to log in or use certain features of the Forum. Where required by law, we will request your consent before placing non-essential cookies.

7. Advertising and Analytics

We use third-party analytics services (such as Google Analytics) to collect and analyze usage data in aggregate and anonymized or pseudonymized form where possible.

We may display advertisements served by third-party advertising networks (such as Google AdSense). These networks may use cookies, web beacons, or similar technologies to collect information about your visits to this and other websites, in order to provide advertisements about goods and services that may interest you. We do not control these third-party technologies, and their use is governed by the respective third party’s own privacy policy.

You may opt out of personalized advertising through your Google Ads Settings, or through industry opt-out tools such as the Digital Advertising Alliance or Your Online Choices, where available in your region.

8. Data Retention

  • Account and profile data is retained for as long as your account remains active, and for a reasonable period thereafter in case you wish to reactivate it.
  • Forum posts and content are generally retained indefinitely to preserve the integrity and continuity of public discussions, unless you request deletion or we are required to remove them.
  • Server log data is typically retained for a limited period (generally up to twelve (12) months) for security and diagnostic purposes, consistent with applicable regulatory guidance.
  • We will delete or anonymize personal data when it is no longer necessary for the purposes it was collected, unless retention is required by law.

9. Data Security

We implement reasonable technical and organizational security measures designed to protect your personal data against unauthorized access, alteration, disclosure, or destruction. These measures include the use of encrypted password storage, HTTPS/SSL encryption for data in transit, firewall and malware protection (e.g., Wordfence), regular software updates, and access controls limiting who can administer the Forum.

However, no method of transmission over the internet or electronic storage is completely secure. While we strive to protect your personal data, we cannot guarantee its absolute security. You are responsible for keeping your account password confidential.

In the event of a personal data breach that is likely to result in risk to your rights, we will notify the Data Protection Board of India and/or affected users without undue delay, as required under the DPDP Act and Rules.

10. Your Rights

Subject to applicable law, you have the following rights regarding your personal data:

  • Right to access: You may request a copy of the personal data we hold about you.
  • Right to correction: You may request correction of inaccurate or incomplete personal data.
  • Right to erasure: You may request deletion of your personal data and/or your account, subject to certain legal or operational exceptions (e.g., we may retain anonymized copies of public posts for discussion continuity).
  • Right to withdraw consent: Where processing is based on consent, you may withdraw it at any time.
  • Right to grievance redressal: You have the right to file a complaint with us, and, if unresolved, to escalate the matter to the Data Protection Board of India (once operational) or, for EEA visitors, your local data protection authority.
  • Right to nominate: Under the DPDP Act, you may nominate another individual to exercise your rights on your behalf in the event of death or incapacity.

To exercise any of these rights, please contact us at the email address listed in Section 1. We may need to verify your identity before processing certain requests.

11. Children’s Privacy

The Forum is intended for users who are at least 18 years of age, or the age of majority in their jurisdiction, or at least 13 years of age with verifiable parental or guardian consent where permitted by local law. We do not knowingly collect personal data from children without appropriate consent. If we become aware that we have collected personal data from a child without appropriate consent, we will take steps to delete such information promptly.

12. International Data Transfers

Our servers and service providers may be located in India or other countries. If you access the Forum from outside India, your information may be transferred to, stored, and processed in a country with data protection laws that may differ from those of your home country. Where we transfer personal data outside India, we do so in a manner consistent with the DPDP Act, which permits transfers except to countries specifically restricted by the Government of India. For users in the European Economic Area, we take reasonable steps to ensure transfers are subject to appropriate safeguards consistent with GDPR requirements.

13. Third-Party Links

The Forum may contain links to third-party websites, including our main site at chemenggcalc.com, calculator tools, or external resources mentioned by members. We are not responsible for the privacy practices or content of third-party websites. We encourage you to review the privacy policy of any website you visit.
