What we do with your voice, in plain English.

Listenin handles audio from conversations that are often sensitive — health, legal, family, school. We've kept this short on purpose.

Who runs Listenin

Listenin is provided by Harry Winteringham, a sole trader based in the United Kingdom, registered with the Information Commissioner's Office (registration ZC112104) as the data controller for the personal data described on this page. You can reach us any time at show email address.

Who is responsible for what

In data-protection language, there are two roles: the controller decides why and how personal data is used, and a processor only does what the controller instructs. It matters because it tells you who is answerable to you.

• We are the controller. We decide that your audio is transcribed, which companies do it, and how long anything is kept. Everything on this page is our responsibility, and the ICO registration above is ours. We are not acting on anyone else's behalf.
• Speechmatics and Anthropic are our processors. They handle your audio and transcript strictly on our instructions, under contracts that hold them to it. They are not free to use your meetings for their own purposes, and neither of them trains AI on what passes through.
• You are the person the data is about — and, when you record a conversation, so is everyone else in the room. Recording your own appointment for your own purposes is your business, and the law largely leaves that alone. But the moment we transcribe it for you, the responsibility for handling it properly is ours, not yours.

So: any meeting sent for transcription is sent by us, as controller, to a processor working to our instructions. It is not sold, it is not shared with anyone else, and it is not used to build anyone's product.

What lives where

• On your phone: the transcripts and summaries we send back, the contacts you save as Trusted People, and your settings. These are protected by your phone's built-in file protection and your passcode, and never leave the device unless you share or email a meeting yourself. When you tap Import from Contacts, Listenin reads your address book on your device to show you a list to pick from; nothing is uploaded, and only the person you choose is saved.
• 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 else touches your data, and for how long

These companies help us run Listenin. Here's exactly what each one sees.

• Speechmatics (speech-to-text) hears your audio while it's being turned into words, on their EU servers. Under our signed agreement with them, anything they hold is kept for no longer than 7 days, and they can only use it to provide the service — never for anything else. Their privacy policy.
• Anthropic (Claude) (plain-English explanations and summaries) sees the transcript text we send it. Under Anthropic's standard terms, that text can be kept for up to 30 days for safety review, then deleted. It is not used to train AI. We're working to switch this to zero retention. If you turn AI off in Settings, none of your transcript is ever sent to Anthropic. Their privacy policy.
• ElevenLabs (voices) — only if you pick the Elsie or Sam voice in Settings. When one of those voices reads something aloud, the text being read is sent to ElevenLabs in the United States to make the audio, with no name or account attached. The default voice, Li, works on your phone and sends nothing anywhere. Their privacy policy.
• Resend (email) sends your sign-in codes and, if you turn on "Email me a copy", the link to your own summary. For meetings you record in the app, it sees your email address and the link, not the meeting content, which stays encrypted. One exception: if you use the try-it demo on our homepage and ask for your demo result by email, that email contains the demo text you typed or read out.
• Render (hosting) runs our server. Standard server logs, no meeting content.

Signing in, subscriptions and what we count

• Sign in with Apple. If you sign in with Apple, Apple sends us a signed token so we can check it's really you. We store the anonymous Apple identifier and the email address Apple shares — which can be Apple's private relay address if you choose Hide My Email. If Apple shares your first name, it stays on your phone; it's never uploaded.
• Email sign-in works as before: we hold your email address and sign-in dates.
• Listenin Plus. Payment is handled entirely by Apple. We never see your card or bank details. Apple sends us a signed receipt, and we keep a small record of whether your account has Plus and when it runs out, so the app works the same wherever you sign in.
• What we count. Two numbers, and nothing else: how many minutes of meeting time your account used this month, and how many meetings have used your free allowance of the Plus features. Both are counts, not recordings — they say how long and how many, never what was said.

The research pack (Plus)

After some meetings, Listenin Plus can offer to look into the things that came up — what a named procedure involves, or a rough guide to a cost that was mentioned. Nothing is looked up until you tap View or Email. When you do, we send short, self-contained questions about those items to Anthropic — never your transcript. If you choose Email and pick one of your Trusted People, the finished research note goes to your inbox and theirs, and you'll see exactly who gets it before anything is sent.

Recording other people

You should only use Listenin 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. Listenin doesn't replace getting that consent; it helps you keep up with what's said and gives you a fair record afterwards. Agreeing to this is part of our Terms, which you accept when you start using the app.

How we ask, and what we ask for

Conversations about health, legal matters or family are what the law calls special category data, and using it needs your explicit consent — a deliberate yes, not a box you walk past. So before your first meeting we ask for exactly one thing: your consent to us processing those meetings, including sending the audio to Speechmatics and the text to Anthropic, so we can give you a transcript and a plain-English note.

That is the only consent we take. Everything else on that screen is us telling you what happens, not asking you for anything. We keep a record of the date, the version of the wording you agreed to, and the app build — so if you ever ask what you agreed to, we can show you. Withdrawing is one tap in Settings, and it wipes your meetings, your contacts and every share link you have made.

Your rights

• Turn AI off completely. Settings → AI Help switches off all AI. With it off, Listenin still transcribes your meeting live and keeps it on your phone, but it makes no summaries, plain-English explanations, or suggested questions, and none of your transcript is ever sent to Anthropic. You can turn it back on anytime.
• See what we have. Settings → My Data shows everything Listenin 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.
• One honest exception. If you signed in, we still hold a small account record (your email address or Apple sign-in identifier, sign-in dates, whether you have Plus, and this month's minutes count) and anonymous feature-usage counts. To remove those too, email show email address and we'll delete your account completely.
• Get in touch at show email address for any other privacy question.

Logs and diagnostics

Our server keeps short-lived operational logs for debugging: connection events, error codes, and how long a transcript was. We also count which features get used (for example, how often Simplify is tapped and for which meeting type) so we know what's helping. When the app is first set up, we count which welcome steps get completed, tied to a random install identifier rather than your name or email, so we can see where new people get stuck. These counts don't include what was said. We don't run third-party analytics or trackers on the website.

Children

Listenin 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 your data is processed

Listenin is built and operated in the United Kingdom. Speechmatics transcribes your audio in the European Union. Anthropic processes summarisation requests in the United States; that transfer is made under the UK International Data Transfer Addendum to the European Commission's Standard Contractual Clauses, together with a transfer risk assessment. If you'd rather nothing went to the United States, turn AI off in Settings → AI Help: your audio is still transcribed in the EU, but no transcript is sent to Anthropic.

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.
