Your voice, handled with care

ummute is made and run in Britain. We are the data controller for what you record, write and tell us. To ask a question, or to use any right described below, email contact.ummute@gmail.com.

ummute is for people aged 18 and over, on the web and on WhatsApp. If you are under 18, please do not use it. If we learn that someone under 18 has used it, we review the account and remove their data.

• Your recordings, the transcripts made from them, and your scores. The audio is stored with Amazon Web Services (AWS) in London.
• If you sign in: your name, your email address and, if you use Google, your profile picture. You can sign in with Google or with a link sent to your email.
• If you choose to give them: your age bracket and gender. They are optional. We use them only to judge your voice against a suitable baseline when we build your plan.
• If you have not signed in: a cookie that recognises you as the same visitor for 30 days.
• Your IP address, each time you use a feature that calls an outside service. We use it to apply free-use limits and to guard against abuse.
• If you link WhatsApp to your account: your phone number and the messages we exchange.
• Your plan and its status. Onelink and Stripe take your card details, and we never see them.

• Your phone number. It is your account.
• Every message you send and every reply you get, in full.
• For a voice note: a transcript and measurements of how you spoke. The note is copied to AWS in London only so that it can be measured, and it is deleted straight afterwards. A rule on that storage removes anything left behind.
• A profile built from your chat: your name, your goal, an estimate of your level, your language, and things you have told us.
• The practice lines we set you, and how each try was measured.
• A safety reading of each message. It looks for signs that someone is under 18 or is in distress.
• The words you used, if you asked us to stop.
• If you arrive from an advert: the details Meta passes on about that advert.

Voice notes you sent to a previous version of ummute on WhatsApp may still be stored as audio in AWS in London. They stay there until you ask us to remove them.

We use your recordings, messages and account details to give you the service you asked for: to measure your speech, to reply, and to keep your history so that you can see your progress. That is necessary to provide the service. Where you give us optional details, such as your age bracket and gender, we rely on your consent, and you can withdraw it at any time.

We rely on our legitimate interests to keep the service secure, to apply usage limits, to measure whether our advertising worked, and to test new versions of ummute. You can object to any of these by email.

We use the companies below. Each one receives only what its task needs.

• Deepgram turns speech into text. It runs in the United States, and its model-training programme is switched off for our requests.
• Our own measuring function, on AWS in London, measures pitch, pace and loudness.
• Google Gemini writes the replies on WhatsApp. It receives your messages and transcripts through Google’s API, which is not in the United Kingdom.
• Anthropic models, through Amazon Bedrock, write the notes on the web. They also help with some WhatsApp tasks, such as the safety reading. They are set to run in Europe.
• ElevenLabs speaks practice sentences aloud. It receives the sentence only, never your audio.
• Meta runs WhatsApp and delivers messages in both directions. Its own terms apply to those messages. Meta also receives advertising measurements, described below.
• Onelink, Stripe’s merchant-of-record service, sells our plans and takes the payment. Stripe runs the checkout. Both receive your name, email, billing address and payment details for the purchase and for tax, and hold your card details.
• Amazon SES sends the sign-in emails.
• Google signs you in, if you choose Google.
• Umami counts visits to the site, without cookies.

Some of these companies work outside the United Kingdom. Where your data goes abroad, we rely on the safeguards that UK law requires for international transfers.

We use the cookies the site needs to work: one that keeps you signed in, one that recognises you as the same visitor for 30 days if you have not signed in, and one that remembers your light or dark setting. Umami counts visits and sets no cookies.

We also advertise, and we measure whether it worked. For visitors outside the United Kingdom, the European Economic Area and Switzerland, the website uses the Meta Pixel, which sets cookies, and we send Meta events through its Conversions API, such as starting a take or signing in. Your email address is hashed before it is sent. Your IP address is sent without hashing.

If you message us on WhatsApp from an advert, and your phone number does not begin with a UK, EEA or Swiss code, we may tell Meta that a conversation began or that a plan was bought. The number is hashed first. We do none of this for visitors in the United Kingdom, the European Economic Area or Switzerland. We do not sell your data.

ummute does not train models on your recordings or your messages. Voice notes go to Deepgram with its model-training programme switched off. That switch went live on 4 October 2026.

We do replay real conversations, with names and contact details removed, to test new versions of ummute before they go live. This is testing, not training. You can object by email to your conversations being used this way.

ummute’s replies are written by software, not by a person. They are not professional, medical or legal advice, and ummute is not a crisis service. If you are in danger or need urgent help, contact your local emergency number.

Reply STOP at any time and ummute sends no more replies until you send START. Today, ummute does not start a conversation with you on WhatsApp. If that changes, we will say so on this page first.

The microphone records whatever you say, and a transcript is sent to the services named above. Do not record anything that you would not want measured and written about.

We keep your data until you ask us to remove it. On request, we remove your account, your recordings and your messages. Our backups may keep a copy until they are next replaced.

Some records are kept by others for their own reasons. For example, Onelink and Stripe keep payment records as the law requires.

Under UK GDPR you can ask to see the data we hold about you, to have it corrected or deleted, to receive a copy, and to object to or restrict how we use it. Email contact.ummute@gmail.com. We usually reply within a month.

If you live in India, Brazil or elsewhere, you can use the same email address to exercise the rights that your own law gives you. You can also complain to your own data-protection regulator. In the United Kingdom, that is the Information Commissioner’s Office (ico.org.uk). We would like the chance to put things right first, but you do not have to wait.

If this policy changes in a way that matters, we will say so on this page, with the date. Where it matters to a conversation, we will also tell you in the chat.
