As a privacy-first and decentralized messaging platform, Backup and Sync is essential to protect your data and maintain secure, anonymous communication. This feature merges local and cloud-stored data to ensure that your account, contacts, and wallet information remain consistent across devices, avoiding login errors or data loss.
You can disable automatic sync in the settings. In this case, the cloud will only store your initial registration data and will not record ongoing messages or wallet changes. However, you assume the risk of potential wallet or contact loss if automatic sync is turned off.
