Privacy Policy: L3M
Effective date: November 3, 2026
Cuprbot Labs Inc. ("we", "us", "our") makes L3M ("the App"), an AI assistant that runs language models on your iPhone or iPad. This page explains what information the App handles, who receives it, and the choices you have.
At a Glance
| What | When | Optional? | Who receives it |
|---|---|---|---|
| Usage events | Automatically while you use the App | No | PostHog |
| Approximate location (country, city) from your IP address | With usage events | No | PostHog |
| Purchase and trial history (anonymous ID) | Only when you start the trial, buy, or restore | Yes | Apple and RevenueCat |

Device Permissions
The App asks for the following permissions only when you use the feature that needs them. You can refuse or revoke each in Settings, and the rest of the App keeps working.
| Permission | What it is used for | Where the data goes |
|---|---|---|
| Camera | Lets you ask a question about a photo you take. | Read on your device and never uploaded |
| Microphone | Listens only while you tap the microphone in the message box, so you can speak a message instead of typing it. | Turned into text on your device; not saved or uploaded |
| Speech Recognition | Shows your spoken words in the message box as you speak, using Apple's on-device speech recognition. | Stays on your device; nothing is sent to a server |
| Photos | Reads the photo you pick so you can ask a question about it. | Stays on your device |
Information Stored on Your Device
The App has no account and no sign-in. Everything you create in the App stays on your device. We do not receive it and cannot see it.
On-Device AI
Your questions, the answers, your files, photos and voice are processed on your device by the AI model you choose, including Apple's built-in on-device model where your device has it. They are stored on your device. Your chats, files and answers never leave your phone, and we cannot see them.
Model Downloads
The App downloads the language and voice models you choose to install, from huggingface.co. Like any website, Hugging Face receives your IP address and the name of the file you request. Nothing you typed or stored in the App is sent with a download. For how Hugging Face handles data, see Hugging Face's Privacy Policy.
Usage Analytics
We use PostHog, a third-party analytics service, to understand how the App is used and to fix problems. PostHog receives anonymous usage events, such as screens viewed and features used, together with the App version, device model, and operating system version.
Events are tied to a randomly generated identifier that is not linked to your name, email address, Apple ID, or any account.
The App does not record your screen. Events name which feature was used, how fast a model answered, and error codes. They never include your chats, files, answers, prompts, or anything you type.
PostHog derives an approximate location (country and city) from your IP address when it receives events.
For how PostHog handles data, see PostHog's Privacy Policy.
Purchases
Purchases are made through Apple. Apple handles payment, and we never see your card number, billing details, or Apple ID. We use RevenueCat to manage purchases in the App. RevenueCat identifies you only by an anonymous app user ID, and uses your purchase history to unlock Lifetime Unlock and to restore it when you reinstall the App or move to a new device.
The free 14-day trial is a $0 purchase that you start yourself. After the trial, Lifetime Unlock is a one-time unlock. There is no subscription. For how RevenueCat handles data, see RevenueCat's Privacy Policy.
Feedback
The App has a feedback form for reporting a bug or suggesting an idea. When you send it, the App sends what you wrote, your choices in the form (such as a star rating), the App version, and your device model and iOS version. Sending feedback is optional, and nothing is sent until you tap Send.
The form has an optional email field. If you fill it in, we use your email only to reply to that feedback. Leave it empty and your feedback is anonymous.
Feedback is stored in the App's database in Apple iCloud (CloudKit), which only we can read. Apple requires you to be signed in to iCloud to send it. Apple attaches an identifier that is specific to this App, and we cannot see your Apple ID, name, or iCloud email.
What We Do Not Do
- We do not require an account or collect your name or Apple ID.
- We do not show ads.
- We do not track you across other apps or websites.
- We do not sell your data or share it with advertisers.
