Key takeaways
- The person acts to say yes; doing nothing never counts.
- Consent should be specific to a purpose, not a blanket yes to everything.
- Withdrawing should be as easy as agreeing.
What makes opt-in consent valid
- India's Digital Personal Data Protection Act, 2023 says consent must be "free, specific, informed, unconditional and unambiguous with a clear affirmative action" (section 6(1)), and that withdrawing it must be comparably easy (section 6(4)).
- The GDPR defines consent as a freely given, specific, informed and unambiguous indication of a person's wishes, by a statement or a clear affirmative action (Article 4(11)), and says it must be as easy to withdraw as to give (Article 7(3)).
- Both tie consent to a stated purpose, so a yes to one use is not a yes to another.
Opt-in consent on WhatsApp
Meta requires businesses on the WhatsApp Business Platform to get opt-in before messaging people. The opt-in must clearly say the person is agreeing to receive messages from the business, and name the business. Meta also suggests telling people how to opt out of categories of messages.
Opt-in vs opt-out
Opt-out means people are included by default and must act to leave, such as being added to a broadcast list without asking. Opt-in means nobody is included until they act. For personal data and business messaging, opt-in is the safer model and the one these laws describe.
How Milvao collects opt-in consent
Members join by sending a message themselves. Introduction requests stay off until a member turns them on, and PAUSE or STOP works at any time. For each request, the member separately allows their number to be shared, and the matched member's Accept is consent to that one introduction. See who sees what. This is general information, not legal advice.
