Effective 2026-09-25. Corollary is made by Handeware LLC.
There are no accounts, no analytics, and no servers operated by us. Nothing you ask is ever sent to us. Some features reach outside services when you use them; each one is described below, and the app keeps a log on your iPhone of what it sent and where.
By default, Corollary answers with Apple Intelligence, on your iPhone. You can also download a model that runs on your iPhone; downloading it contacts Hugging Face (huggingface.co), which receives the request for that file.
On iOS 27 you can choose Apple Intelligence's Private Cloud Compute to answer. Then what you ask, and what the app reads to answer (for example, calendar entries you asked about), is sent to Apple's Private Cloud Compute to answer it, under Apple's own privacy protections for that service. It is never sent to us.
If you add your own key for Anthropic, OpenAI or Google Gemini, the app asks you before anything is sent. Once you allow it, what you ask goes to that provider under your own account and its terms, together with any photos or files you attach and what the app reads to answer (for example, calendar entries you asked about). Remove the key to stop.
If you point the app at a model running on your own network, or add a tool server, what you ask goes to the server you chose.
When a question needs it, the app reads public web pages and public data: for example Wikipedia and Wikidata, images from Wikimedia Commons, Google News headlines for a topic, weather from Apple Weather, Apple's charts and search for music, films, books and apps, Stack Exchange answers, share prices, exchange rates, and public datasets such as U.S. Treasury Fiscal Data, the U.S. Bureau of Labor Statistics, openFDA, the World Bank, OpenAlex, Crossref, CoinGecko, Zippopotam.us, the Free Dictionary API and TVmaze. Each receives the words being looked up and your IP address, as any website does. None of them receives your conversation.
Questions about things to buy, a home's value or flight fares are answered by reading the stores' and sites' own pages (for example Amazon, Target, Walmart, Zillow, Realtor.com or Google Flights) in a hidden browser on your iPhone. Each site receives the words being looked up and your IP address. A barcode you scan is looked up the same way, by its number; the photo stays on your iPhone.
If you allow location access, your position is sent to Apple Maps when you ask for something nearby or for directions, and when a card shows places near you, and to Apple Weather when you ask about the weather where you are. The app does not store it. Place names (never your position) may also be looked up with OpenStreetMap's Nominatim or Open-Meteo.
Read on your iPhone, read-only, and only when you ask about them. They are not sent anywhere unless you use cloud AI with your own key or Apple's Private Cloud Compute (above). A question that needs the web never carries them.
Photos you choose are read on your iPhone with Apple's Vision framework, and speech is turned into text on your iPhone (the first time, iOS may download Apple's speech model). Neither leaves your iPhone unless you ask a cloud AI you have enabled about them.
After your first five games, one game in five asks whether you will watch a short video ad from Google AdMob to make it. Say no and that game is not made; nothing else changes. If no ad is available, the game is made anyway. Ads appear there and nowhere else. Google's SDK receives a device identifier, ad interaction and diagnostic information, for frequency capping, fraud prevention and reporting; Google's own policy governs what it does with them (policies.google.com/technologies/partner-sites). Every ad request is non-personalised: the app never asks for tracking permission, so your advertising identifier is not available to it. Your questions, documents and answers are never part of an ad request.
Your chats, the app's log of what it sent, your bookmarks and the search data the app learns from what you tap are stored only on your iPhone. Chats, the log and bookmarks are included in your iPhone's own backups; the learned search data is not, and iOS may clear it when storage runs low. Games you make are kept on your iPhone too. The share extension, the widgets and the Siri shortcuts are part of the app on your iPhone and send nothing on their own. Deleting the app deletes all of it.
Corollary is not directed at children under 13.
