Your walk home companion
Hi, I'm Luna.
I'll walk you home.
Chat all the way home. One code phrase quietly alerts your contact.
- No account
- Set up in a minute
- UK, 18+
How it works
- Step 1: Chat on the way
Like a call with a friend. Hold your phone on speaker so you can still hear what's around you.
- Step 2: Get help quietly
Say your code phrase, tap the moon 5 times, or tap Alert. Your contact gets a text with where you are, and Luna keeps chatting as normal.
- Step 3: Home safe
Tap “I'm home” to finish. Plus a fake call to get away, notes, and open places nearby.
For use in the UK only: you and your contact both need to be in the UK.
Built with a specialist domestic abuse adviser (IDVA). Luna is a demo, not an emergency service: in danger, call 999.

Your privacy
- Your voice isn't recorded. What you say goes live to ElevenLabs, the voice AI service, so the companion can answer (ElevenLabs uses Anthropic's Claude AI to write the replies, or OpenAI's if Claude is slow). A second, listen-only line turns what you say into text, to catch your code phrase the moment you say it. Your first name and code phrase are sent too, so it knows what to call you and what to listen for. The app tells ElevenLabs not to keep recordings and to delete the conversation within a day.
- Your contact's name and number and your code phrase stay in this browser tab until you close it (or tap “Wipe them now” after a walk), unless you choose Remember me. During an alert, the contacts it may go on to (if nobody says they've seen it) are kept on our server until it's seen or called off. Texts to your contacts go through Twilio, which keeps a copy.
- Your location stays on your phone, except: a rough location (about 100 m) to find open places nearby, where you were for each note, and your contact's private link if you share your walk or send an alert. The link stops when the walk ends (or an hour after its end time, if your phone loses signal).
- Notes you ask for are kept on this phone until you delete them. Unless you switch the backup off, they're also kept privately for 90 days in case they're needed, for example by the police. Only the person running this demo can look them up, and every look-up is logged. You can delete the backup from the privacy page.
- With Remember me, your name and contacts are saved in this phone's browser only, never on our servers. “Forget me” wipes them, and what the companion remembers.
- Memory, if it's on. The companion can remember small, everyday things you chat about, like a match or a deadline. They stay on this phone, never on our servers. At the start of each walk they're shared with the voice service, which deletes them within a day. You can delete them, or switch memory off, on the companion step.
