Captcha Stash

Keep your secrets safe from AI

Free · Designed for iPad

Now with Military Grade encryption Captcha Stash – The Human-Only Vault Captcha Stash is a next-generation vault that ensures only humans can access sensitive notes and private information. Whether you're storing personal thoughts, confidential data, or secret plans, this app keeps everything locked down behind a human-only barrier: CAPTCHA verification. KEY FEATURES Human-Only Authentication Choose from visual, math, word, or pattern-based CAPTCHA challenges. Bots and AI can't get through — only a real person can. On-Device Storage All your data stays on your device. Notes are encrypted and stored locally. Nothing is uploaded. Ever. Self-Destruct After Failed Attempts Configure the number of failed access attempts. If someone fails too many times, all notes are wiped for your security. Secure and Private No user accounts. No cloud backups. No analytics. Captcha Stash doesn’t track you, log you, or sell your data. Minimal Note Interface Jot down ideas, passwords, thoughts, or sensitive information in a clean, distraction-free environment. Customizable CAPTCHA Modes You decide how to verify access: tap colored shapes, solve simple equations, unscramble words, or complete sequences. All processed locally. Fully Offline and Ad-Free Works entirely offline. No ads. No internet connection needed to use the app or access your data. WHY USE CAPTCHA STASH? Unlike fingerprint locks, passwords, or cloud vaults, Captcha Stash doesn't trust machines. It's designed for people who want absolute privacy, full local control, and human-proof security. If machines ever take over, they won't get your notes. Captcha Stash is perfect for: Personal journals Business ideas Private plans Local-only sensitive data Anyone who wants to keep AI out Privacy First Captcha Stash stores everything locally and encrypts your data. The app has no server, no telemetry, and no tracking. You are in complete control. No recovery means real security. If you delete the app or reset your device, your notes are gone — just like a real vault. Only human minds can unlock Captcha Stash.
