HOW IT WORKS Your family/group/team shares a private set of three words that rotate automatically on every device. When someone calls or messaging claiming to be someone they are not and asking for important information, just ask: "What's the words?" If they can't answer, it's not them. Call over. Scam stopped. If they can, you know they have the app installed and that it's them. For extra layers of protection, request a Proofie (a biometric stamped selfie). The words generate locally on your phone. No server, no cloud, no internet required. They rotate on a timer so even if someone overhears today's words, they expire. SET UP IN 60 SECONDS 1. Download Trust Onion 2. Create a group or join one with an invite code 3. Everyone in the group sees the same three words 4. That's it. You're protected. No accounts required for basic use. No passwords to remember. No tech skills needed. WHEN WORDS AREN'T ENOUGH, SEND A PROOFIE A Proofie is a verified selfie that proves a real person took it. It includes your current codewords overlaid on the photo, your location, a timestamp, and a cryptographic signature tied to your device. You can't fake it with AI. You can't replay an old one. The words change, the location is live, and the signature is locked to your phone's biometrics. Ask a family member to send a Proofie when you need proof beyond words. BUILT FOR PRIVACY Trust Onion was built with one rule: your family's data stays on your devices. Codewords are calculated locally. No personal data is collected or stored on our servers. The app works fully offline. Biometric authentication (Face ID or fingerprint) stays on your device and is never transmitted. We can't see your codewords, your Proofies, or your family groups because we never receive them. WHO IT'S FOR Parents and families who've seen the voice cloning headlines and want a plan. Teams who could have team maters impersonated and risk security hacks. Adult children worried about aging parents answering scam calls. Anyone who wants a dead-simple way to verify the people they love are really them. Trust Onion is free. Protecting your family shouldn't cost anything. ## Key features - Rotating family codewords - Offline codeword generation - Verified selfies (Proofies) - Live location and timestamp - Cryptographic signature - Biometric authentication - No internet required ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/trust-onion-ai-scam-protection/id6758185539/reviews.md ### 5/5 — Easy to setup, helps our family feel safe *2026-06-29* I downloaded this a few weeks ago and while we haven't had to use it during an emergency (thankfully) it was super easy to set up with my older parents so that we have a “family group” and changing passwords. I even checked and it worked when it was in plane mode. It’s free, it works, so definitely recommend if you are worried about family getting scam calls/texts. ## Frequently asked questions about Trust Onion AI Scam Protection ### What is Trust Onion? Trust Onion is a mobile application designed to help users verify the identity of callers, especially against AI voice cloning scams. It uses a system of rotating family codewords and verified selfies (Proofies) to ensure the person on the other end is who they claim to be. ### How does Trust Onion protect against scams? Trust Onion uses a shared, rotating set of three codewords that only family members know. If someone calls claiming to be a family member but cannot provide the current codeword, it signals a potential scam. Additionally, 'Proofies' provide verified selfies with live location and timestamps that are difficult to fake with AI. ### Does Trust Onion require an internet connection? No, Trust Onion is designed to work fully offline. The codewords are generated locally on your device, and no server or cloud connection is required for its basic functionality, ensuring privacy and accessibility. ### Is Trust Onion free to use? Yes, Trust Onion is free to use for its core features, including codeword generation and basic Proofie sharing. The app aims to make family protection accessible without cost. ### What information does a Proofie include? A Proofie is a verified selfie that includes your current codewords overlaid on the photo, your live location, a timestamp, and a cryptographic signature tied to your device. This makes it extremely difficult to forge or reuse an old Proofie. ### How often do the codewords change in Trust Onion? The codewords rotate automatically on a timer, ensuring that even if someone overhears today's words, they expire and become invalid. This dynamic system enhances security against potential eavesdropping. ### What is the age rating for Trust Onion? Trust Onion has an age rating of 4+, making it suitable for a wide range of users. The app's interface is designed to be simple and easy to use for all family members. ### How is my data protected with Trust Onion? Trust Onion prioritizes privacy by keeping all family data on your devices. Codewords and Proofies are not collected or stored on their servers. Biometric authentication also remains on your device and is never transmitted. ## Version history (last 5 releases) ### 2.4 — 2026-07-09 Ai Protection Center Updates: Ai Voice Analyzer - helps users determine if a callers voice might be Ai generated.
