Personalize Lumo and change how it looks

You can tell Lumo about yourself and how you’d like it to respond, so you don’t have to repeat it in every chat. You can also change Lumo’s theme and text size.

Personalize Lumo’s responses

You need a Proton Account to personalize Lumo. Your answers are zero-access encrypted.

2. Fill in any of the following:
   • What should Lumo call you?
   • What do you do?
   • Anything else Lumo should know about you? For example, your interests, your level of expertise, or how you like to learn.
   • How should Lumo behave? Write your own instructions, or select traits to add them:

Trait	What it does
Chatty	Conversational and engaging responses
Witty	Clever humor and wordplay when appropriate
Straight-shooting	Tells it like it is, without sugar-coating
Encouraging	A supportive and motivating tone
Gen Z	Modern slang and a trendy style
Traditional	A formal, conventional approach
Forward-thinking	Progressive and innovative perspectives

3. Select Save.

To clear everything, select Reset all.

Lumo uses your personalization in all your chats, including chats in projects.

Personalization or memory?

• Personalization is what you write here: a short description of you and your preferences. It applies to all chats, including projects.
• Memory is a list of details Lumo saves over time, from your chats or that you add yourself. It isn’t used in projects.

Change how Lumo looks

1. Go to Settings → Appearance.
2. Change any of the following:
   • Theme: Light, Dark, or System to match your device.
   • Font size: Very small, Small, Medium (recommended), Large or Very large. This changes the size of text across the app.
   • Animated background: turn the animated background on the home screen on or off. If your device’s reduce motion setting is on, the animation is already turned off.

Appearance settings are available to everyone, including people using Lumo without an account.
