    question: 'How does matching work?',
    answer:
      "When you and your partner both answer positively to the same question (yes or maybe), it's a match! You'll both be notified and a private chat thread opens for that question. Your individual answers remain private until there's a match.",
  },
  {
    question: 'Are my answers private?',
    answer:
      "Absolutely. Your individual answers are never revealed to your partner. They only see questions where you've both answered positively. If you say no to something, your partner will never know.",
  },
  {
    question: 'What happens if my partner says no to a question?',
    answer:
      "Nothing! They won't know you were interested, and you won't know they said no. The question simply doesn't become a match. This creates a safe space to be honest about your desires.",
  },

    question: 'Do both partners need Pro?',

      "No! When one partner upgrades to Pro, both partners automatically get full access to all premium packs. One subscription covers your entire relationship.",

    question: 'Is my data secure?',

      'Yes. All chat messages are end-to-end encrypted, meaning only you and your partner can read them. We take your privacy seriously and never share your data with third parties.',
