Akismet is a spam-filtering service that checks comments, form submissions and forum posts on websites. It uses machine learning and is accessed through an account and an API for developers. The service is operated by Automattic, which presents itself as the maker of WordPress.com, Jetpack and WooCommerce. Akismet is a hosted service and is not offered as open source software.
Automattic Inc. is headquartered in San Francisco, California, and names no foreign parent. Akismet's privacy page says that transfers outside the EEA are made under Standard Contractual Clauses included in a Data Processing Addendum available to users. It also states that data is stored on servers located around the world and that most spam-related data is deleted after between two weeks and ninety days. For a European organisation this means a US-headquartered operator and transfers to non-EU locations, with no EU-only hosting commitment stated.
