Children under 13 are prohibited from using X, and this minimum age threshold triggers specific legal obligations around minors' data under COPPA in the US and GDPR-related children's data protections in the EU.
By using X, you grant the platform an extremely broad, royalty-free license to use, modify, and distribute your content worldwide, while X's financial liability to you is capped at just $100. X can suspend or terminate your account not just for rule violations, but also for prolonged inactivity or what it deems 'commercial inviability', with limited recourse available to most users. You can deactivate your account at any time by visiting your account settings to terminate the agreement.
