| Purpose | Codewars helps people improve coding skills by practicing community-created programming exercises called kata. | The site aims to help people explore unfamiliar areas and learn new concepts in a fun, recreational context. |
| Security | Codewars says it uses physical, technical, organizational, and administrative security measures appropriate to the personal data and its processing, while noting no internet transmission or storage method is completely secure. | The site says connections use HTTPS and that passwords and account recovery keys are hashed using PHP’s one-way password hashing algorithm. |
| Support | The About page lists [email protected] as a contact address. | Privacy or security concerns can be sent to [email protected]; other queries are directed to the alternative forum. |
