Plain English. Last updated: November 2026 · Private beta
Larzo holds some of your most personal thoughts, so we want to be precise and honest about how we handle your data. This policy describes what's true today, during our private beta. We'll update it as Larzo grows, and we'll never claim more protection than we actually provide.
The details are below.
Your data is encrypted in transit and at rest. We decrypt it only when needed to provide Larzo's features, for example to write your morning note or respond to you. It is not used for advertising, and it is not sold.
To organize what you share, Larzo gives each memory and reminder a broad topic label, like "work", "travel" or "birthdays". We use these labels only in aggregate: we count them across all users to understand what people use Larzo for and where to make it better. We never look at any one person's labels, and we never report a total that covers fewer than 5 people. These labels are stored without encryption so they can be counted.
We're being deliberately precise here: Larzo is not end-to-end encrypted. To do its job, our systems (and the AI provider below) process your information in readable form at the moment a feature runs. We don't claim otherwise.
To understand and respond to you, Larzo sends your conversations to our AI provider, Anthropic (the makers of Claude), through their API. Anthropic does not use data sent through their API to train their models. Your conversations are processed to generate Larzo's replies, not to train public AI models.
Most of the time Larzo has no live internet access. It answers from what you've shared and from Claude's own knowledge. In the web app, in limited cases, when you ask about something that needs current information, Larzo can do a web search to answer. We built this to protect you: the search is built only from the words you typed, never from your stored memories; your memories and history are never sent to the search; the lookup runs in a separate, isolated process that can't reach your account or data; and a reply that used a web search isn't saved as a memory. Web search is off by default and is currently enabled for only a small number of testers while we refine it.
To work, Larzo stores your first name, your email, your phone number if you add one for texts, and what you share with it (your messages and the memories built from them). It uses these only to remember things for you, reply to you, check in with you, send any reminders you ask for, and email you about Larzo. You can unsubscribe from email anytime. Like any website, we also keep basic technical records, such as sign-in activity and error logs, to keep the service running.
If you provide your mobile number and check the SMS consent box on our signup form (or during onboarding in the app), Larzo may send you recurring automated text messages: the reminders and check-ins you signed up for. Message frequency varies. Message and data rates may apply. Reply STOP at any time to opt out, or HELP for help.
We collect your mobile phone number and the date and time of your consent solely to deliver these messages. Your number is transmitted only via our messaging provider (Twilio) for that sole purpose.
We do not share, sell, or provide your mobile phone number or messaging consent data to third parties or affiliates for marketing or promotional purposes.
You can delete your memories whenever you want. When you do, we remove them from our active systems and age them out of backups on a set retention schedule (backups are not kept forever, but they may persist for a short period before they cycle out).
Larzo is a personal helper, not a doctor, therapist, or emergency service. If you're in crisis or need urgent help, please contact a qualified professional or your local emergency services.
Larzo is for adults 18 and older. Please don't use it if you're younger than that.
As Larzo develops, we'll update this policy and note the date above. If we make a meaningful change to how we handle your data, we'll let you know.
