Common questions

Do I need an account to use Luminary?: No. You can start asking questions straight away as a guest. Creating an account saves your chat history across devices, lets you share chats, and keeps your saved highlights.
Where do I find my previous chats?: Open the menu from the top left of the chat screen. Your chats are listed there, and you can rename or delete any of them. Guest chats are tied to the device and are not restored if you reinstall the app.
How do I change the app's language?: Settings → Language. This changes both the interface and the language Luminary replies in.
I'm not getting notifications.: Check Settings → Notifications in Luminary first. If it says notifications are turned off in your device settings, you'll need to allow them for Luminary in your phone's own Settings app — Android and iOS both block them at that level regardless of what the app asks for.
How do I delete a single chat?: Open the chat menu from the top left, then use the options on the chat you want to remove and choose Delete session. This cannot be undone.
How do I delete my whole account?: In the app: open Profile, tap the three-dot menu in the top right, and choose Delete Account. You can also do it from a browser on our account deletion page, which also lists exactly what is deleted and what is kept.
An answer looked wrong.: AI-generated answers can be inaccurate or incomplete, so please check the sources shown alongside an answer before relying on it — especially for medical, legal or financial questions. If something looks seriously wrong, email us the question and we'll look into it.
A document or image won't upload.: Uploads need a stable connection, and very large files can time out. Try again on Wi-Fi with a smaller file first. If it still fails, email us and tell us the file type and roughly how big it is.
I've been charged or want a refund.: Purchases made through the app are handled by Google Play or the App Store, so refunds have to be requested through them. Email us as well and we'll help sort out anything on the account side.

What to include when you email

The more of this you can tell us, the faster we can help — most of it saves a round trip:

What you were trying to do, and what happened instead.
Your device and its operating system version — for example, Pixel 8 on Android 15, or iPhone 14 on iOS 18.
Whether you were signed in or using Luminary as a guest.
Roughly when it happened.
A screenshot or screen recording, if you have one.

Please don't send passwords or verification codes. We will never ask you for them.
