Is Worldcoin safe to use?

Worldcoin is not something I’d call low-risk to use. The main issue is that it involves biometric data, which is especially sensitive because you can’t change an iris like you can change a password.

In practical terms, the biggest safety considerations are:

• Privacy risk: you’re trusting a system that collects and processes biometric information. Even if the service says it deletes raw iris images after processing or uses privacy-preserving methods, you should still treat any biometric collection as high-stakes.
• Regulatory risk: availability and legality can vary by country, and rules or local scrutiny can change over time. Check the current status where you live.
• Crypto risk: if you’re using it for the token incentive, remember that cryptocurrency prices can be highly volatile and are not a reliable source of value.

So the short answer is: Worldcoin may be acceptable only if you’re comfortable with significant privacy and regulatory risk, and you’ve verified the current terms in your location. If you’re privacy-sensitive, the safer choice is usually to avoid giving biometric data to any service unless you have a strong reason and have checked the current policy carefully.

Before using it, verify:

1. The current privacy policy and data-retention settings
2. Whether the service is legally available where you live
3. Whether your biometric data is stored, deleted, or used for verification in any way
4. Whether the token incentive is worth the privacy tradeoff
