Decentralized Applications (DApps) offer enhanced security due to their inherent decentralized nature. Traditional centralized apps store data on single servers, making them vulnerable to hacks and breaches. In contrast, DApps store data across multiple nodes on a blockchain, ensuring that even if one node is compromised, the data remains secure. Additionally, transactions on DApps are encrypted and immutable, meaning they can't be altered once recorded. Regarding privacy, many DApps are built on public blockchains, so while transactions are transparent, users' identities are protected through cryptographic pseudonyms, ensuring anonymity.
