Captcha Stash is a local-storage note-taking application that secures sensitive data behind mandatory CAPTCHA verification. By requiring human-only authentication for access, it provides a unique security layer for private information without relying on cloud connectivity or user accounts. ## Key Features - **Human-Only Authentication**: Protects notes using visual, math, word, or pattern-based CAPTCHA challenges to prevent bot access. - **On-Device Storage**: Ensures all encrypted data remains stored locally on the user's device with no cloud uploads. - **Self-Destruct Mechanism**: Automatically wipes all stored notes after a user-configured number of failed access attempts. - **Privacy-First Design**: Operates without user accounts, analytics, or data tracking. ## Who is it for? Privacy-conscious individuals seeking a secure, offline environment for storing sensitive notes and private data. ## Links - [App Store](https://apps.apple.com/us/app/captcha-stash/id6749536677?uo=4) - [Full Intelligence Report](https://marlvel.ai/apps/captcha-stash) --- *This is an overview report.
