You need the internet only to buy or restore your subscription (Apple handles that). Once that's done, your Pro status is saved on your device. After that, everything in the app works offline — chat, projects, voice. We don't have subscription servers; Apple does the billing.

No. All chat, voice input, and projects run on your phone or tablet. You only need internet if you want to purchase or restore Pro.

No. Once you've purchased or restored, Pro works offline. You'd only need internet again if you get a new device and want to restore your purchase there.

No. Nothing you type, say, or add to projects leaves your device. Everything is processed on your iPhone or iPad.

Pro is for future extra features. The app itself stays private and works offline; subscription is optional and helps support development.

Yes. If the app is installed, it works without Wi‑Fi or cellular.

On your device only — in the app's storage. We don't keep a copy on our servers.

No. We don't collect analytics, usage data, or crash reports.

No. You can chat, use projects, and use voice input without signing up. You only need your Apple ID if you decide to buy Pro.

We never see your data. Apple handles the App Store and purchases, not the content of your chats or projects. Your content stays in the app on your device.

No. Voice input uses Apple's on-device speech recognition. Your voice stays on your device. You can also turn off "Improve Siri & Dictation" in iOS if you prefer.

They're gone. We don't have a copy. Back up anything important before uninstalling.

It means the AI runs on your iPhone or iPad. Your words and documents never go to our servers or anyone else's.

The app comes with a built-in language model that runs on your device. There is no option to load or switch to a different model.

Some answers show a "Thinking" part above the reply. That's the model's reasoning step — you can expand it if you want to see how it got to the answer.

The app shows the answer as it's being generated, so you see it appear gradually instead of waiting for the whole thing at once.

If you switch to another app, generation may stop. For long answers, keep SimpleLM open.

Each device has its own chats and projects — they don't sync. You can restore your Pro subscription on each device with the same Apple ID.

The app includes a built-in language model for chat and support for projects (your documents). You cannot add or replace the model.

No. The app does not support loading your own model files. It uses only the built-in model.

No. You cannot add or replace the model. The app comes with a single built-in model; there is no option to load your own.

Because it includes an AI model that runs on your device. That's why the download is big — everything runs locally.

The model is built into the app and cannot be removed separately. You can free space only by removing the app or by managing your projects and documents.

A project is a place where you add your own documents (e.g. PDFs, text). The app then uses them to answer your questions — so answers are based on your content.

PDFs and text files. The app reads the text and uses it when you chat in that project.

There's no set limit. It depends on your device's storage.

No fixed limit. Very large numbers of big documents might use a lot of storage and take longer to index.

No. They're processed only on your device. Nothing is uploaded.

When you chat inside a project, the app uses your documents to answer. So asking questions in that project is how you "search" — the answers are based on your files.

It means the app finds relevant parts of your documents and uses them to write the answer, instead of answering from general knowledge only. So you get answers based on your content.

Tap the microphone in the input bar, speak, then tap again to stop. The text appears in the message box; tap send when you're ready.

It uses Apple's speech recognition, so it depends on your device's language and what Apple supports in your region.

Yes, if your device has on-device speech recognition for your language. You can check in iOS Settings under Siri & Search.

No. Create, rename, and delete chats as you like.

Very long messages might get cut off by the model's limits. Shorter messages usually work best.

Running AI on the device uses a lot of power. Long conversations or big projects can make the device warm and use more battery. Closing other apps can help.

Yes. Use it in line with the app's terms. Your data stays on your device; you're responsible for how you use the answers.

iPhone and iPad with iOS 17 or later. It's built for Apple devices with modern chips.

Plan for several GB — the app and its model are large. Add more if you use lots of projects or big documents.

v1.1 is for iPhone and iPad only. A Mac version may come later.

Usually the app's built-in model is missing (e.g. the app wasn't fully installed). Try reinstalling the app.

In v1.1, Pro is optional. Core features work without it. When Pro is enabled, it may add extra features or higher limits — see the app's Subscription screen for details.

Open the app → Settings → Subscription (or Billing) → Restore purchases. You need internet once; after that, Pro works offline.

Check the Subscription screen in the app or the App Store listing. In v1.1, the main features work without a subscription.

The app is designed to keep your data on your device and can use iOS encryption. Your content doesn't leave the device.

Your chats and projects are only on that device. We don't have a copy. Use iCloud Backup if you want the app's data included in your backup.

If the phone is unlocked, they can open the app. Use a passcode, Face ID, or Touch ID, and don't leave the app open when you're not using it.

SimpleLM runs only on your device: no account required, nothing sent to the cloud, and it works offline. Many other assistants send your input to their servers and need the internet.

We're always improving. v1.1 focuses on chat, voice input, projects, and clear formatting. New features are announced in the app or release notes.

Look in the app under Settings or About for support or feedback links. When you contact us, describing your device and what you did helps, since we don't collect usage data.
