What we do with your voice, in plain English.
Listen in handles audio from conversations that are often sensitive — health, legal, family, school. We've kept this short on purpose.
Last updated 30 April 2026
The short version. Your recordings live on your phone. Audio is streamed live to a transcription service so it can be turned into text, then it's gone — never written to disk on our servers. When you share a meeting summary with someone, we store an encrypted copy that we ourselves cannot read. You can delete everything at any time, from inside the app.
What lives where
- On your phone: the audio you record (briefly, until processed), the transcripts and summaries we send back, the contacts you save as Trusted People, and your settings.
- On our server: only the encrypted contents of meetings you have chosen to share. The decryption key never reaches us — it lives in the share link itself, in a part of the URL that browsers never send to servers.
- Briefly in transit: audio while it's being transcribed, and transcript text while we generate plain-English summaries. Neither is written to disk.
Sharing without a back door
When you tap "Share with someone", your phone encrypts the meeting locally with a fresh random key, sends only the scrambled blob to our server, and embeds the key in the share link. The link looks like listenin.uk/meeting/abc123#k=.... Browsers don't send the part after the # back to servers, so we never see a key alongside the data we hold.
If you forward that link to someone, their phone or browser uses the key to decrypt the page on the device. If you delete the link in Settings, the encrypted blob is removed from our database — and even before you delete it, we couldn't read it.
What we don't do
- We don't store your audio. It's processed in memory and dropped.
- We don't store the title, summary, or transcript of meetings on our server in plain form. Shared meetings live as ciphertext only.
- We don't sell your data, share it with advertisers, or use it for marketing.
- We don't use your transcripts to train AI.
- We don't track you across other websites or apps.
Who sees the audio briefly
Two third parties process your data while it's being turned into text and summarised. Both have committed not to store it.
- Speechmatics — speech-to-text. Audio is streamed to their EU servers, transcribed, and discarded. Their privacy policy.
- Anthropic (Claude) — plain-English summaries. Transcript text is sent for summarisation and not retained on their side. Their privacy policy.
Recording other people
You should only use Listen in for conversations you're part of. Laws on recording private conversations vary — in many places you must tell the other person, and in some you must have their explicit consent. Listen in doesn't replace getting that consent; it helps you keep up with what's said and gives you a fair record afterwards.
Your rights
- See what we have. Settings → My Data shows everything Listen in stores about you on this device and on our server.
- Delete a single meeting. Tap any meeting and choose Delete to remove it from your phone.
- Delete every meeting. Settings → Delete All Meetings wipes the local library.
- Delete everything, including shared links. Settings → Delete All My Data wipes the local library, your saved contacts, and revokes every share link this device has ever created.
- Anyone with a share link can revoke it — there's no account login involved.
- Get in touch at hello@listenin.uk for any other privacy question.
Logs and diagnostics
Our server keeps short-lived operational logs for debugging — connection events, error codes, and how many characters a transcript reached. We have specifically excluded transcript content and AI prompt content from these logs. We don't run third-party analytics or trackers on the website.
Children
Listen in isn't designed for use by children under 16. If you're using the app in conversations involving a child, please get the parent's or guardian's consent first.
Where we are based
Listen in is built and operated in the United Kingdom. Speechmatics processes your audio in the EU. Anthropic processes summarisation requests in the United States. By using Listen in you agree to those transfers. If you'd rather your data stayed in a particular region only, please don't use the app — there isn't currently a region-locked option.
Changes to this page
If we change anything important here, we'll update the "Last updated" date above and, where it affects you, let you know in the app the next time you open it.
