Core Philosophy	Zero-Trust Sovereignty: Trust only yourself and open standards.	Open-Source Trust: Trust in transparent, auditable code and hardware.	Air-Gapped Security: Maximum security through physical isolation. Bitcoin-only focus.	Mobile-First Convenience: Focus on DeFi/NFT users and accessibility via mobile app.
2FA / TOTP Authenticator	YES: Uses Multi-Factor Encryption. Decryption requires Password + Pepper + a time-based 2FA/TOTP code. (2FA/TOTP only in Advanced and Ultimate version.)	NO: (Trezor only supports U2F, it cannot store and show TOTP secrets like Google Auth.)	NO: (Device has no such feature.)	NO: (Device has no such feature.)
Hardware/ Vendor Dependency	ZERO: Use, re-use, or upcycle any old phone or computer. No need to buy specific hardware, wait for delivery, or trust a vendor's supply chain. Your backup is timeless and independent of the company.	TOTAL: Requires proprietary hardware and their specific mobile app to function.	TOTAL: Requires proprietary hardware and their specific mobile app to function.	TOTAL: Requires proprietary hardware and specific software platforms to function.
Data Versatility	Any Text Data. Store passwords, private keys, bank data, seed phrases, etc. (over 2100 chars) in the form of an encrypted QR code.	Crypto & Passwords. Manages crypto assets and integrates with password managers.	Bitcoin Only. Does not support other cryptocurrencies or data types.	Crypto Assets Only. Manages keys derived from a single seed phrase.
Anonymity & Privacy	100% Anonymous. No personal information required.	High. No KYC required for purchase or use.	High. No KYC required for purchase or use.	High. No KYC required, but heavily tied to Binance ecosystem.
Censorship risk by gov. and authorities	Extremely Low. No entity can be forced to block or restrict access. Only possible if the user chooses to comply and share the passwords.	Low. The device is offline, but the Trezor Suite app could be a point of censorship.	Very Low. No direct identity link, but firmware updates could be targeted by authorities in the future.	Low. The device is offline, but the mobile app (via App Stores) is a point of censorship.
Cost Model	One-Time Purchase. Unlimited use.	Hardware Purchase. For multiple locations multiple purchases needed.	Hardware Purchase. For multiple locations multiple purchases needed.	Hardware Purchase. For multiple locations multiple purchases needed.

Resilience & Disaster Recovery

Scenario	Paranoid Qrypto	Trezor	Coldcard	SafePal
Backup Redundancy	Simple & Cheap. Print or Laser engrave unlimited copies for different locations at minimal cost.	Manual. Relies on a paper recovery sheet. No Encryption only plaintext. The device itself is a single point of failure.	Manual. Relies on a paper recovery sheet. No Encryption only plaintext. The device itself is a single point of failure.	Manual. Relies on a paper recovery sheet. No Encryption only plaintext. The device itself is a single point of failure.
Data Redundancy (SSS)	Built-in Shamir's Secret Sharing: Split your backup into multiple pieces you control and optionally encrypt in addition.	Yes. Supports Shamir's Backup (SLIP39), but requires multiple paper backups.	Yes. Can export Shamir shares to microSD cards which in turn suffer from dataintegrity loss and BitROT.	None. The standard paper backup is a single point of failure.
Fire & Flood Damage	Immune. A laser-engraved metal backup survives house fires and floods.	Vulnerable. The electronic device and its paper backup are both destroyed.	Vulnerable. The electronic device and its paper backup are both destroyed.	Vulnerable. The electronic device and its paper backup are both destroyed.
EMP / CME Event	Immune. An Laser engraved metal backup has no electronic components.	Vulnerable. The device is electronic. The paper backup is immune.	Vulnerable. The device is electronic. The paper backup is immune.	Vulnerable. The device is electronic. The paper backup is immune.
Long-Term Data Integrity (Bit Rot)	Immune.Physical Laser engraving on metal does not degrade over time as easy, it can last for centuries if properly stored.	Vulnerable. The device's flash memory is subject to data degradation and BitROT. The paper backup is more stable but can fade. it is also not Encrypted, stored in plaintext.	Vulnerable. The device's flash memory is subject to data degradation and BitROT. The paper backup is more stable but can fade. it is also not Encrypted, stored in plaintext.	Vulnerable. The device's flash memory is subject to data degradation and BitROT. The paper backup is more stable but can fade. it is also not Encrypted, stored in plaintext.
Backup Method	Encrypted QR Code on a physical medium you control (paper, metal).	Manual backup of seed phrase on paper or other physical medium, only UNENCRYPTED, UNSECURE PLAINTEXT.	Manual backup of seed phrase on paper or other physical medium, only UNENCRYPTED, UNSECURE PLAINTEXT.	Manual backup of seed phrase on paper or other physical medium, only UNENCRYPTED, UNSECURE PLAINTEXT.
Future-Proofing	Excellent. A QR code is a simple visual pattern. It will be readable for centuries. on Proper Metal.	Poor. Relies on the company, USB standards, and desktop operating systems.	Poor. Relies on the company, USB standards, and desktop operating systems.	Poor. Relies on the company, mobile OS updates, and app store availability.

Beyond Backups: Replace Your Hardware Wallet Entirely

While Paranoid Qrypto creates indestructible backups, its ultimate power lies in its ability to transform a device you already own into a sovereign signing device—making dedicated hardware wallets obsolete.

The Ultimate Paranoid Protocol:

1. Find Your Device: Take any old smartphone or laptop that you no longer use for daily tasks.
2. Create the Air-Gap: Perform a factory reset and ensure it never connects to the internet, Wi-Fi, or Bluetooth again. This is now your permanently offline air gapped signing device.
3. Install Paranoid Qrypto: Transfer the Paranoid Qrypto application file to the device via a trusted SD card or USB data device.
4. Create Your Indestructible Backup: Encrypt your seed phrase password or any text up to around 2100 characters into a QR code and transfer it out via SD card to be engraved on metal via direct capable Laser Engraver or Printer to print on paper, as many copies as you desire. This is your permanent backup.
5. Sign Transactions Securely: Use your air-gapped device with a compatible wallet app of your choice to sign transactions by scanning QR codes. Your private keys never touch an online machine.
6. Store or Destroy: For maximum security, you can power down and store your signing device in a safe place, or delete/format or even destroy it, knowing you can always recreate it on another old or new device using your indestructible QR code backup.

Why This Replaces a Hardware Wallet:

• Cost-Effective: It's free. You reuse hardware you already own instead of buying a new device.
• More Secure: A truly air-gapped, single-purpose device has a smaller attack surface than commercial hardware that must connect to online computers.
• Sustainable: Give your old electronics a new, high-security purpose instead of sending them to a landfill.
