What's coming next
More apps in testing, same privacy promise. Every one of these processes data entirely on your device.
Sirrius
Pet Health
Your pet's health records, meds, and vet visits — tracked by on-device AI that never sends their data off your phone.
The Promise
Privacy isn't a feature. It's the architecture.
Every app follows the same rules
- All data processing happens on your device — not "mostly" on-device, entirely
- No user accounts. No sign-ups. No email collection. Open the app and start using it
- No analytics SDKs, no tracking pixels, no fingerprinting. We don't know who you are
- AI features use Apple's on-device models. Your data never hits a server
- One-time purchases or optional subscriptions. Free tiers are fully functional, not crippled demos
- Delete the app and everything goes with it. There's nothing on our end to delete
