To reduce the risk of deleted Wickr data being recovered, the Secure Shredder runs whenever your Wickr app is running. The goal is to “sanitize” or overwrite deleted Wickr data, on a best-effort basis.
While Secure Shredder is a strong additional step to protect your data, please be aware that there are various platform-specific functions, including cloud backup services, that continuously make copies of files or interfere with file deletion in ways that could impact the effectiveness of this feature. For instance, the deleted data may be backed up before it’s shredded or overwritten by the shredder. So it’s important to know that the feature is built as a best effort tool to significantly reduce, not eliminate risk.
