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 hello@listenin.uk.

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.
• 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. We are confirming their exact retention settings for our account and will state them here plainly once we have it in writing. 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. 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.

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.

Your rights

• 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 with your email, we still hold a small account record (your email address and sign-in dates) and anonymous feature-usage counts. To remove those too, email hello@listenin.uk and we'll delete your account completely.
• 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 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. 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 your data stayed in one region only, there isn't a region-locked option today, so please don't use the app.

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.
