Every product we build answers the same question: What if software actually worked for the person using it?
Private menstrual cycle tracking for iPhone
After the Dobbs decision overturned Roe v. Wade, menstrual tracking apps became a flashpoint in the privacy debate. Law enforcement agencies began subpoenaing health data from apps that promised privacy but stored everything in the cloud.
Women across America started deleting their period trackers. Not because they didn't need them, but because they couldn't trust them.
Cara was built to solve this. It's a menstrual cycle tracking app that runs entirely on your iPhone. Your data never leaves the device — not to our servers, not to Apple's cloud, not anywhere. There is no server. There is no account. There is nothing to subpoena.
Cara uses on-device computation for all cycle predictions and tracking. The app stores data exclusively in the device's local storage using encrypted containers. No internet connection is required to use any feature.
The prediction engine uses established medical models for cycle forecasting, running entirely within the app's sandboxed environment. No data is transmitted, collected, or accessible to anyone other than the device holder.
There are over 50 million women of reproductive age in the United States. After Dobbs, searches for "private period tracker" surged 3,000%. The existing market leaders — Flo, Clue, and others — all rely on cloud storage and have faced scrutiny over data sharing practices. The demand for a truly private alternative isn't theoretical. It's urgent.
On-device keyboard with private talk-to-text for iOS
Every time you use your iPhone's default keyboard, Apple has the ability to log what you type. Every time you use voice-to-text, your voice is sent to Apple's servers for processing. Third-party keyboards like Gboard send your keystrokes to Google.
Your keyboard sees everything — passwords, messages to loved ones, private thoughts, medical searches. It is the single most intimate interface on your device.
Privacy Keyboard is a replacement iOS keyboard with a fully on-device talk-to-text engine. Voice transcription happens on your phone's neural processor, never touching any external server.
The keyboard itself operates in a sandboxed environment with no network access. It doesn't request "full access" — the iOS permission that would allow it to transmit data. It physically cannot send your keystrokes anywhere.
The mobile keyboard market is dominated by Gboard (1B+ installs) and SwiftKey (500M+), both owned by the two largest ad companies on earth. There is no major keyboard app built on a privacy-first model. We're targeting the growing segment of privacy-conscious users who understand that their keyboard is the most surveilled interface on their device.
On-device AI that never phones home
Siri, Google Assistant, and Alexa all work the same way: they record your voice, send it to a remote server, process it in the cloud, and send the result back. Every question you ask, every command you give, every conversation overheard — it all passes through their servers.
Amazon employees have listened to Alexa recordings. Apple contractors heard Siri recordings of medical conversations, drug deals, and intimate moments. Google stored voice data indefinitely. These aren't bugs — they're features of the business model.
Private Assistant is a custom AI model engineered to run entirely on the neural processing hardware already built into modern smartphones. No cloud. No server. No recording sent anywhere.
The model is optimized for on-device inference using quantization and distillation techniques that allow it to run efficiently on mobile hardware while maintaining useful conversational ability. Your assistant lives on your phone and only on your phone.
Modern smartphones ship with powerful neural processing units (NPUs) specifically designed for on-device AI. Apple's A-series and M-series chips, Qualcomm's Hexagon DSP, and Google's Tensor processors all have dedicated AI hardware. But the software running on them still sends everything to the cloud. The hardware is ready. The software just needs to catch up.
Private QR code generator for Android
Digital Eclipse is our proof of concept — a powerful QR code generator that works entirely on your device. URLs, WiFi credentials, contact cards, plain text — generate QR codes for anything without an internet connection, without tracking, without ads.
Most QR code generators on the Play Store are ad-infested, require unnecessary permissions, and route your data through external servers. A QR code for your home WiFi password? That gets sent to someone's cloud. A QR code for your business card? Same thing.
Digital Eclipse generates everything locally. It's fast, it's clean, and it's free — because generating a QR code on a device that's perfectly capable of doing it locally shouldn't cost a subscription or your privacy.
Digital Eclipse demonstrates our core thesis: useful software can be built to run entirely on-device, offered for free, and still provide a better experience than the ad-supported alternatives. It's our first product on the market and the foundation for everything that follows.
