Screen Health Larry is an iPhone app that helps the people in a group, such as a family or a group of friends, see how much time each of them spends on their phones. The short version: it collects your first name and minutes of app use, and shows them only to the group you join.
What we collect
- Your first name, which you type when you set up.
- A group name and group code, to start or join a group. You choose who to give the code to.
- Minutes of use per day for the apps you choose to share, for example “Instagram: 52 minutes today”, and when your phone last checked in.
- A random account token, kept on your phone and on our server, so the app knows it is you. There is no email or password.
- The year you were born, which we use to check you are 13 or older and to compare you with people your age.
- Optionally, after you have used the app for a while: your country and, if you are an adult, your state and gender. We only keep state and gender for people 18 and older.
- Your phone number, only if you add it (you can skip it). We keep a scrambled copy, never the number itself, so Larry can tell which people in a group chat have an account. You can remove it any time.
How we get your screen time
The app uses Apple’s Screen Time framework. You choose each app in Apple’s own picker, and the app only learns how many minutes it was used. It cannot see what you do inside an app.
What we don’t collect
The app never reads your messages, and it does not collect what you do inside apps, browsing history, your location, contacts, photos, or an advertising ID. The one exception is Larry in a group chat, below, and only in a chat that adds him.
Larry in your group chat
Larry can also join a group chat in iMessage. He only joins when the group adds him and sends his link code, and he ignores every other conversation.
- In a chat he is in, he reads the messages there so he can answer and get to know the group. Everyone in the chat is told this when he joins.
- Recent messages are kept for 14 days, then deleted. Larry also keeps a short private notebook for that chat, such as nicknames and inside jokes, for up to 90 days. He is told not to note anything about health, family, relationships, money, religion, politics, ages or location.
- To tell who in the chat has an account, Larry looks up the phone numbers of the people in the chat and compares them with the scrambled numbers in the app. Numbers of people who don’t have an account are not saved.
- So the app can show who is in the chat but hasn’t joined yet, Larry shares a scrambled copy of the phone numbers of the people in a chat he has joined, never the numbers themselves. It is deleted when he leaves.
- Each chat is kept separate. Larry never uses one chat’s notes or messages in another.
- To write his replies, the recent chat is sent to an AI service (through OpenRouter) set to providers that do not keep it or train on it.
- Anyone in the chat can say “larry forget that”, “larry pause”, or “larry leave” to have him forget a note, stop listening, or leave and delete that chat’s messages and notes.
Comparisons
The app can show how your screen time compares with groups of people, such as Gen Z, or Gen Z in California. These are totals and typical values for a whole group, shown only when the group has at least 20 people. When a week ends, Larry’s roast of whoever finished last may say that a large group, such as Gen X, did better, but only a group that person is not in, so it never reveals anything about them. Nobody sees another person’s age, gender or location, and we never show a comparison that could point to one person.
Your contacts
If you choose to, the app can show your friends’ names and photos from your contacts. To do that it reads phone numbers from your contacts and sends only those numbers to our server, which checks them against the scrambled numbers of the people in your group and answers which ones match. We don’t save the numbers you send. Names and photos from your contacts never leave your phone. You can turn this off in Settings.
Who sees it
- The other members of your group, whoever you invited, see your first name and your minutes, in total and for each app you share.
- A group’s leaderboard can also be opened on the web with the group code, so only share your code with people you want to see it.
- We do not sell your data, use it for ads, or share it with data brokers.
- Your app data is stored with our hosting provider, Cloudflare, who process it for us. Larry’s group chat data stays on a computer we run.
Your choices
You pick which apps to share and can change that in the app at any time. Deleting the app stops any new data. To have your name and usage deleted from our servers, email dylan@albertazziventures.com. We keep your data until you ask us to delete it.
Children
The app is not meant for children under 13.
