Are open-source comic readers secure? What are the security considerations?

Open-source code is generally considered more secure because it’s publicly accessible for auditing. However, security isn't guaranteed. Regularly check for updates to patch vulnerabilities. Be cautious about granting excessive permissions to the app. Always download apps from trusted sources (like the Play Store or F-Droid). Avoid installing apps from unknown developers, and be wary of apps requesting access to data that seems unrelated to their functionality.
