Privacy policy
Version 2026-10-27. This policy covers the Articulate Coach Android app and the service behind it. Articulate Coach is published by Limitless LLM, a business name of Darboux Pty Ltd (ACN 703 601 709).
The short version
- You practise conversations out loud. We record your side, transcribe it, measure how you spoke and write you a coaching report.
- Creating an account means you agree that we record your side of conversations and drills, and send your transcripts to Anthropic in the United States for the partner and the coaching.
- Audio is transcribed and analysed in Australia, on our Google Cloud servers and Deepgram's in Sydney. The conversation partner and the written coaching are generated by Anthropic's AI in the United States.
- Your audio is kept for 30 days unless you choose otherwise in Settings. Transcripts and reports are kept until you delete your account.
- When you delete your account, we start deleting 24 hours after you ask and everything is gone within 48 hours, apart from the few things listed under "What is left after deletion".
- We never sell your data, never show ads, never train AI models on what you say and never use your voice to identify you.
- Your conversation partner and your coach are AI, not people.
- Articulate Coach is for adults: you must be 18 or over.
Who we are
Articulate Coach is run by Darboux Pty Ltd, an Australian company, trading as Limitless LLM ("we", "us"). We decide what personal information the app collects and how it is used, and we are responsible for it.

What Articulate Coach is
Articulate Coach is communication practice. You hold spoken conversations with an AI partner in everyday and work scenarios, and you get feedback on how you spoke: measurements of your delivery and a written report about your words. Our Terms say what the service is not.
The app measures how you speak. It does not identify people. We never use your voice to identify you: no voiceprints, no voice login and no telling one speaker from another.
What you agree to when you create an account
When you create an account you agree to this policy and our Terms. That includes two things the coaching cannot work without:
- Record my side of conversations and drills. We record your side of each conversation, drill and voice snapshot, transcribe it and measure how you spoke, as "What we collect" describes.
- Send my transcripts to Anthropic in the United States for the partner and the coaching. Anthropic's AI writes your conversation partner's lines and your coaching from your transcripts, as "Who we share it with" describes.
If you do not agree to both, please do not create an account. You can stop at any time by deleting your account in Settings, which deletes what we hold as "Deleting your account" describes.
How the law applies to us
We handle your personal information as if we are bound by the Privacy Act 1988 and the Australian Privacy Principles, whether or not the small business exemption applies to us, and this policy is written to meet them, including the rule on automated decisions that starts on 10 December 2026. The Australian Consumer Law applies to what we tell you here.
What we collect
Your account. Your email address, your password (stored only as an argon2 hash, which cannot be turned back into the password) and the display name you choose. The partner uses the display name to address you in conversations.
Your questionnaire answers. Up to ten questions, each with a stated use. Seven are asked when you first open the app, and each needs an answer before you go on; the other three are asked only in Settings, where any question can be skipped:
| Question | What it changes |
|---|---|
| What brought you here, and how often it happens | Which skills and practice paths we suggest first, and where your drills start |
| Whether you plan what you will say, and where it goes wrong most | Which skills and practice paths we suggest first |
| Where it matters most | Which situations your suggested paths and scenarios practise. A plain summary ("preparing for interviews") is sent to the AI coach so it knows what matters to you |
| How much time you have | The order of the practice paths we suggest |
| How you heard about us | Nothing for you. Only our own statistics |
| Which best describes you (Settings only) | Adds scenarios that fit where you are. The label you chose is sent to the AI coach |
| Is English your first language (Settings only, optional, "Prefer not to say" is an answer) | Only how the coach words its notes. If you answer no, the AI coach (Anthropic, in the United States) is told that you learned English later, and to judge your word choice against your listener, never against you, and never to mention it. Never used for statistics or marketing |
| How you feel about speaking up (Settings only, optional) | How hard your first scenarios are and where your drills start |
Before you create an account, the app sends your answers to the onboarding questions to our server so it can suggest where to start. They are not stored on our server until you create an account.
You can change or clear your answers at any time in Settings. Clearing deletes them on our server.
What you agreed to. That you agreed to this policy and our terms when you created your account, and to any later version, with the version and the date. This is how we show you agreed.
Your voice. The audio of each of your turns in a conversation, the recording of your side of the whole conversation, your drill attempts, your practice takes, and the one-minute voice snapshot you can record before you subscribe. We record only while you are in a conversation, a drill or the snapshot. While the microphone is on, your phone shows its microphone indicator (Android 12 and later) and, if you allow notifications from the app, a notification.
Transcripts. Word-for-word text of both sides of every conversation, of your drill attempts and of your snapshot, including filler words such as "um". We also keep how sure the speech-to-text service was of each word, so the app can show you which words were hard to make out.
Measurements. Numbers computed from your audio: pace, pauses, filler words, pitch variety, loudness and how your sentences end. We compute them on our own server.
Coaching reports. The AI-written report on each conversation, which quotes you and gives an opinion about how you spoke, the retry exercises it suggests and the comparisons between attempts. A report can include one of your sentences rewritten more directly ("Say it like this"); when you play it, a synthetic voice reads the rewritten sentence, and we keep that clip with the conversation's recording. Your snapshot result: what we measured in it, the first thing to work on, and one sentence rewritten.
Sensitive information. We do not ask for health information or any other sensitive information, and you do not need to give any. If you mention it in a conversation, it becomes part of your transcript and report like anything else you say. You can ask us to delete that conversation (see "Deleting your account").
Progress. Your skill levels, practice history and settings (such as how long we keep your audio).
Reports you send us. When you use "Report this response", the reason you pick, your note, and which response it was.
Your subscription. Whether you have an active plan, its dates and state, and the purchase token Google Play gives us to check it. We never see your card or bank details: Google Play handles payment.
Security and technical data. Our hosting keeps request logs with your IP address, your device's user agent and the address it asked for. We count sign-in attempts per IP address and per email address to stop password guessing. We also count requests for onboarding suggestions per IP address, for 15 minutes, to stop misuse. We keep a record of each device you are signed in on, with the device name the app reports. Logs never contain your transcripts or audio.
On your phone. In storage only the app can read, it keeps copies of your recordings while they wait to be uploaded, the clip from your last microphone check, a record of what you agreed to, and your answers to the onboarding questions, with the path you picked, until your plan is set up. Signing out or deleting your account removes that record, those answers and any conversation recording not yet uploaded. Uninstalling the app removes everything.
Crash reports. None today. If we switch on a crash-reporting service, we will name it here first. It would receive technical details such as the error and the phone model, never your transcripts or audio.
How we collect and hold it
You give us most of it directly in the app. Measurements are computed from your audio on our server. Reports and the partner's replies are written by AI from your transcript and measurements. Google Play tells us about your subscription.
We store everything with Google Cloud in Sydney, Australia. It is encrypted in transit and at rest.
Why we use it
- To run the service: the conversation, the transcript, the measurements, the report, the drills and your progress.
- To choose scenarios and drills that fit what you told us.
- To run your account and your subscription, and to decide whether a conversation can start (see "Automated decisions").
- To answer you when you contact us or report a response.
- To keep the service secure and to stop abuse, such as password guessing.
- To count, in total, how the app is used (for example how many conversations were held in a week), so we can improve it. These counts do not identify you.
We read a transcript only when you report a problem, when you ask us to, or when the law requires it.
What we never do
- We never sell your data or share it for advertising. There are no ads in the app.
- We never use your recordings in marketing.
- We never train AI models on what you say, and our AI providers do not either.
- We never use your voice to identify you.
- We never score emotion, confidence or accent.
Who receives it
These providers process data for us. Each one receives only what its job needs.
| Provider | What it does for us | What it receives | Where | How long it keeps it |
|---|---|---|---|---|
| Google Cloud (Google LLC and its affiliates) | Hosting, database, audio storage, background jobs and logs | Everything listed above | Sydney, Australia. Google support staff may see data from other countries when we ask them for help | As long as we keep it (see "How long we keep it") |
| Deepgram, Inc. | Turns your speech into text, and gives your partner a voice | The audio of your turns, drill attempts, practice takes and snapshot; the partner's lines, which can contain your display name; and the rewritten sentences it reads aloud for "Say it like this" | Your audio and text are processed in Sydney. Deepgram keeps account and usage records in the United States | We switch off Deepgram's model-improvement programme on every request. Until our data processing agreement with Deepgram is signed, its standard terms also let it use what we send for its own business purposes. Request records 90 days. Summarised usage records are kept longer by Deepgram in the United States |
| Anthropic, PBC | Writes your partner's replies, your coaching report, the comparison of two attempts and the rewritten sentence in your snapshot | Both sides of the transcript, your display name, the scenario, your measurements, your goal and situation labels, and the first-language instruction described above. The transcript of a retry, to check it against the exercise's aim. The transcript of your snapshot. In the few drills with a live partner, the text of your last few lines | United States | Up to 30 days, or up to 2 years if its safety systems flag a conversation. Safety scores its systems attach to a request, up to 7 years. It does not train on them |
| Google Play (Google LLC and its affiliates) | Takes payment for the subscription | Your purchase and subscription state | Under Google's own terms and privacy policy |
We do not send email from the app today. Mail you send to [privacy@ address] or [support@ address] is held by our mailbox provider, which we will name here when our company's mailboxes are set up.
Data that leaves Australia
Yes, some of it goes to the United States:
- Anthropic receives what is listed in its row above. Every request we send asks Anthropic to process it only in the United States. One older Anthropic model cannot take that setting; while we use it for the short comparison of two attempts and for your snapshot's rewritten sentence, Anthropic may process those two requests in other countries where it runs its service.
- Deepgram keeps account and usage records about our requests in the United States.
- Google support staff may see data from other countries when we ask them for help.
Anthropic works for us under its Commercial Terms and data processing addendum. They say it processes the data to provide the service to us and does not train on it. We remain responsible for how our providers handle your information.
How long we keep it
| Data | How long | Then |
|---|---|---|
| Your audio: conversation turns, the whole-conversation recording, drill attempts, practice takes, the snapshot | Your choice in Settings: delete after analysis, 30 days, 90 days, or keep. The default is 30 days | Deleted by a daily sweep. With "delete after analysis", deleted as soon as the analysis finishes |
| "Say it like this" clips (a synthetic voice reading a rewritten sentence) | As long as the conversation's recording | Deleted with it. Never kept once the recording is gone |
| Transcripts, measurements, coaching reports, the snapshot result, skill levels, practice history, your reports of responses | Until you delete your account | Deleted 24 to 48 hours after your request |
| Email, display name, password hash, questionnaire answers, what you agreed to | Until you delete your account. You can clear your answers at any time | Deleted 24 to 48 hours after your request |
| Subscription records | Until you delete your account | Deleted, except one purchase record per subscription (see below) |
| Purchase records for tax | As long as Australian tax law requires us to keep business records (generally five years) | We delete them by hand at the end of that period |
| Request logs (IP address, user agent, address requested) | 30 days | Deleted automatically |
| Sign-in attempt and onboarding suggestion counters (IP address or email address) | Counted for 15 minutes to an hour | Old counters are cleared out as new ones are written |
| Database backups | 7 days, rolling | Deleted automatically |
| Deleted audio files | 7 more days in Google Cloud's recovery store | Deleted automatically |
| A copy of your data we prepare when you ask for it | 7 days | Deleted automatically |
| At Anthropic and Deepgram | As in their rows above | Deleted by them |
Deleting your account
- In the app: Settings, then Delete your account.
- On the web: the delete your account page, with your email and password.
We mark your account for deletion straight away. 24 hours later we start deleting every recording, transcript, report, answer and setting, and your account itself. Everything is gone within 48 hours of your request.
What is left after deletion:
- Backup copies of the database, and deleted files (your audio, and any copy of your data we prepared for you) in Google Cloud's recovery store, for up to 7 more days.
- Request logs, for up to 30 days.
- What Anthropic and Deepgram keep, as in the table above.
- One record per subscription, for tax: its latest order number, the product and its start and end dates. It does not contain your name, email or any account identifier.
- One record that a deletion happened: a one-way code made from your email address, the dates, and how many items were deleted. It cannot tell us your email address, but if you give us the address again we can confirm the account was deleted. We have not yet set an end date for these records; when we do, this policy will say so.
Deleting your account does not cancel your Google Play subscription. Cancel it in Google Play first (Google Play, Payments and subscriptions, Subscriptions).
You cannot yet delete a single conversation in the app. Email [privacy@ address] and we will delete it for you.
Seeing and correcting your data
While you have an active subscription, most of your data is in the app: your history, reports, progress, answers and settings. You can change your display name, your answers and your audio setting in Settings.
For anything else, or for a full copy, email [privacy@ address] from the email address on your account. We may ask you to confirm the request from that address. We answer within 30 days, and it is free. A full copy comes as a download link that works for 7 days: a zip file holding your data in one JSON file, your audio and a short note explaining them.
A transcript records what was said, so we do not rewrite it. If you think a transcript or a report is wrong, we can delete it, or attach your own statement to it.
Complaints
Email [privacy@ address]. We acknowledge your complaint within 3 business days and answer it within 30 days.
If you are not satisfied with our answer, you can complain to the Office of the Australian Information Commissioner (OAIC): oaic.gov.au, phone 1300 363 992.
How we protect it
- Everything is encrypted in transit and at rest.
- The app can reach only your own recordings and reports, through your signed-in account.
- Passwords are stored only as argon2 hashes. Sign-in attempts are limited.
- Only we can reach the production systems, and only through Google Cloud's access controls.
- Our logs never contain transcripts or audio.
- If a data breach is likely to cause you serious harm, we will tell you and the OAIC as soon as we can.
Using the app without your real name
Your display name can be anything you like. We need an email address to run your account. In scenarios that ask for personal details, such as an address or a bank balance, make them up: nothing in a scenario is checked.
Age
Articulate Coach is only for people aged 18 or over. You confirm your age when you create an account. If we learn that an account belongs to someone under 18, we close it and delete its data.
Automated decisions
Computer programs make these decisions about you without a person, using fixed rules that apply the same way to everyone:
| Decision | Personal information used |
|---|---|
| Whether you can use the app beyond signing in, your data and deleting your account | Your Google Play subscription state, which we check with Google using your purchase token, and any complimentary access we gave you and its end date |
| Whether you can start a new conversation | How many conversations you have started in this billing period (15 are included). New conversations also pause if the whole service reaches its daily limit, which protects it from runaway costs; that limit uses no information about you |
| Whether you can record the voice snapshot again | Whether you have already completed it, and how many times you tried today (up to 3) |
| Short blocks on signing in, and on some requests | How many recent attempts came from your email address or your IP address |
AI writes your coaching reports, skill levels and suggestions. They are feedback for you: they do not decide your access, your price or anything about your account.
If you think one of these decisions about you is wrong, email [privacy@ address] and a person will look at it.
Changes to this policy
The version and date are at the top. When we change something that matters, we will tell you by email or in the app before the change takes effect. If the change affects what you agreed to when you created your account, the app will ask you to agree again before you next record.
