# Information Security 1. The platform does not store user private keys in any form and cannot retrieve your private keys by any means. Private keys are encrypted and stored locally in the user's browser. 2. After you clear your browser data, the private key information will also be cleared. Please make sure to back up your private keys before operating. 3. No one, including the platform, can obtain your private key data, but due to the browser's specificity, please make sure to timely update the browser version and open the website in a secure hardware and network environment. 4. For the smart interaction section, some projects require continuous interaction with the contract. The platform will pre-sign the interaction content and upload it to the server for encrypted storage. The platform will not sign any transactions unrelated to the interaction. --- # 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.
