Secure AI is a personal assistant built on one promise. The AI provider never learns who you are. Meet your assistant Pick a glowing orb or a friendly character, give it a name, and it lives in your menu. It shows when it's working, when it's done and when something needs you. Tap it to see what's on today or to plan your day. Just ask. It's done. Ask the chat to remind you to call the dentist on Friday and it goes in Reminders. Ask it to block out time and the event lands on your calendar. It asks before it adds anything, and everything it did is listed in the reply. Feed Today's news from publishers you know, in one place. Ask about any story in a tap. Apps Turn on Calendar, Reminders and Health and your assistant can use them. Health is read on your iPhone. Files from your device are kept encrypted in your Library. Private by design Names, places, companies, email addresses and phone numbers are replaced with stand-ins before your message leaves your device, then restored in the reply. The provider gets the question. Never the person asking. Photos are handled the same way. Faces are covered and location data is removed before anything is uploaded. Add your own words at any time. Anything on the list is replaced from your next message on. See for yourself A privacy claim you cannot check is a slogan. The Protected screen lists every request that left your device and which details were replaced. Compare it with what you sent. On every Apple device iPhone, iPad, Mac and Apple Watch, in 39 languages. Reporting Any reply or image can be reported from inside the app. Touch and hold the message and choose a reason. Reports are reviewed by a person. Plans Free every day. Plus, Pro and Ultra raise your limits and add more capable models. In short • Your name never reaches an AI provider • Your email address never reaches an AI provider • Your IP address never reaches an AI provider • Your conversations are encrypted in transit Support: https://secureai.one/support Privacy Policy: https://secureai.one/privacy-policy Terms of Use (EULA): https://secureai.one/terms
