# Security & Privacy ## Security DEXPIRY is based on smart contracts that were previously audited by an independent third party, and no vulnerabilities were found in their code. The DEXPIRY application was created in accordance with current security standards for the most popular operating systems (Windows, Android, iOS, macOS) and is considered as safe as the device on which it is used. ## Privacy DEXPIRY provides its users with a basic authorization level (*Basic User*) complete privacy when using the application and does not require the entry of personal data when creating a new account, which makes it fully compliant with GDPR. DEXPIRY requires the identities of users who have the authorization level necessary to create DEXPIRY tokens (*Token Issuer*) and those who have insight into the monitoring of all DEXPIRY tokens on the blockchain (*Regulator/Arbiter*). DEXPIRY application uses End-to-end encryption (E2EE) when sending messages and exchanging information between application users. DEXPIRY token transactions are permanently stored on the Blockchain and are transparent and publicly available, but apart from the Blockchain addresses that participated in the transactions, they do not contain any link to the identity of the application user. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
