Amazon Echo Buds

You can review and delete your Alexa voice recordings, one by one, by date range, or all at once. You can also set up an auto-deletion to automatically delete recordings older than 3 or 18 months. You can choose to not save any voice recordings, at the cost of some features. If you choose not to have any voice recordings saved, the text transcripts of your requests will be still retained for 30 days, after which they will be automatically deleted.

Note that even when audio or text records are deleted, Amazon may still retain other data concerning your interactions, such as all records of actions Alexa took in response to your request. They say this allows them to do things like continue to provide your reminders, timers, and alarms, process your orders, remember the things you've taught Alexa, and show your shopping and to-do lists and messages sent through Alexa Communications.

If your request was processed by an Alexa skill, deleting your voice recordings does not delete any information that was authorized to be given to and retained by the developer of that skill. Skill developers do not receive voice recordings, but they may be receiving recordings' transcripts or records of actions Alexa took in response to your requests. This is problematic, because a big share of more than 100,000 skills are developed by third parties that are not necessarily bound by Amazon’s privacy policies. The research by North Carolina State University found that "23.3% of 1,146 skills that requested access to privacy-sensitive data either didn't have privacy policies or their privacy policies were misleading or incomplete. For example, some requested private information even though their privacy policies stated they were not requesting private information." In addition to misleading privacy policies, issues included things like developers being able to claim fake identity ('Samsung', 'Apple'), multiple skills sharing the same Alexa trigger words, etc.

If you chose not to use Alexa with this product, your privacy could be better protected.

Amazon collects data from third parties about you, to target ads better: "Some third-parties may provide Amazon pseudonymized information about you (such as demographic information or sites where you have been shown ads) from offline and online sources that we may use to provide you more relevant and useful advertising."

Amazon's privacy statement is not entirely clear regarding deletion rights: "To the extent required by applicable law, you may have the right to request access to or delete your personal information. If you wish to do any of these things, please contact Customer Service. Depending on your data choices, certain services may be limited or unavailable."
