Privacy Policy

Effective 28 October 2026Updated 28 October 2026v2026.10.8
On this pageWho this covers

AmphiVox lets people answer forms by speaking instead of typing. This policy explains what data that involves, where it goes, and what you can do about it.

AmphiVox is an independent project operated by an individual developer. It is currently offered free of charge. We do not sell data, we do not show advertising, and there is no third-party analytics or advertising software anywhere in the product.

Who this policy covers

Two different people use AmphiVox, and the difference matters:

TermWho they are
CreatorSomeone with an account who builds a form and shares it.
RespondentSomeone who answers a form by speaking. Respondents usually have no account. One is needed only where the Creator requires sign-in, or to use the browser extension.

For answers submitted through a form, the Creator decides what is asked and why. They are responsible for that data. We only process it on their behalf, to run the form and deliver the responses where they have chosen. In data-protection terms the Creator is the controller and AmphiVox is the processor.

If you answered someone’s form and want your answers corrected or deleted, contact the person or organisation whose form you filled in — they hold that data. If you cannot reach them, write to us at contactus@amphivox.com and we will help where we can.

For a Creator’s own account details, we are the controller and this policy governs directly.

What we collect

The browser extension works differently from a form built in AmphiVox. You use it with your own AmphiVoxaccount, on a Google or Microsoft form that someone else made, and no Creator is involved. It inspects supported forms locally when they load so it can show the dock and recognize their questions. This local inspection does not send form content to AmphiVox. During a voice session it sends AmphiVox your speech, the form’s questions and options, the answers currently on it (including ones you typed yourself), and the form’s own message when it rejects an answer. It also sends whether the form’s tab is on screen, so the assistant waits for the form before moving to its next page or finishing. The form’s id and title are kept in that session’s technical and usage records. Your connection token and your one-time agreement stay on your device. Nothing on the form is sent before you start a session or after it ends.

Chrome Web Store. The AmphiVox Extension’s use of the information it collects adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. That information is used only to fill in the form you are answering. It is not sold, not used for advertising or to decide creditworthiness, and is transferred only to the service providers in section 6 that run the voice session. People read it only as section 3 describes for diagnostic logs.

From Creators

WhatWhy we have it
Name and email addressFrom your Google sign-in, to identify your account.
Your formsThe questions and settings you create.
Connected account credentialsIf you connect Google Sheets, Google Drive or Microsoft Excel, we store access tokens so responses can be delivered there. These are encrypted.
Usage recordsSession counts, durations and processing costs per form, for our own accounting. A usage view for Creators is not yet generally available.

From Respondents

WhatWhy we have it
Your speechCaptured while a voice session is running, to work out your answers, and — only if you choose to dictate one — while you record a short feedback note. See section 3.
Your answersWhatever the Creator’s form asks for. This may include your name, email, phone number, address or uploaded files.
Session technical dataConnection identifiers and timings, so a session can run and be debugged.
Feedback you leaveA rating and any note you leave after a voice session, with the session and form it relates to, and your email if you are signed in or a device identifier if you are not (see section 10). We use it to improve the product.
Your account, if you are signed inIf you answer a form while signed in, your account id and email are recorded against that form, so a one-response-per-person rule can work.
We do not store your IP address. When you open a form, AmphiVox checks your IP address against a list of country ranges to work out whether you are in a region we currently serve well, so we can warn you if the voice connection is likely to be slow. That check happens while the request is being answered and the address is then discarded — it is never written to a database, never written to a log file, and never linked to you or your answers. Our hosting provider, our relay server that carries the audio connection, the delivery networks listed in section 6 and, in an Express voice session, OpenAI (your browser connects to it directly for the audio) necessarily receive your IP address in order to deliver the traffic. Our relay server does not log it; the hosting provider, the delivery networks and OpenAI may log it under their own policies.

Voice data

This is the part most people want to know about, so it is stated plainly.

  • Your microphone is used in two places, and only after your browser asks your permission: while a voice session is running, and if you choose to dictate a note on the optional feedback card shown after a session. You can refuse, or stop at any time.
  • Recordings of your voice are not saved. Audio is streamed to a speech-recognition provider, converted to text, and discarded. It is never written to a file or database.
  • Express mode. When a session uses Express, your microphone audio is streamed to OpenAI. Its model listens to the audio directly and replies in its own synthesised voice, so the speech-recognition and speech-synthesis providers above are not used for that session. We do not save the audio. OpenAI may keep what it receives for up to 30 days, solely to detect abuse, under its own terms.
  • Dictating feedback. The feedback card that can appear after a session lets you speak a short note instead of typing it, up to 30 seconds. If you use it, the recording is sent to our speech-recognition provider once, converted to text, and discarded — the audio is never stored. The resulting text is kept if you send it, or if you close the card with text still in it; clear the text first if you do not want it saved. Typing is always available instead, and dictation is never started without you pressing the microphone button.
  • The text of what you said is sent to an AI model so it can work out which answer belongs in which field.
  • While the session runs, your answers are held in memory only. When the session ends they are discarded. Only what you actually submit is stored as a response. The text of the conversation, including answers you gave but did not submit, can remain in the diagnostic logs described below for up to 7 days.
  • Diagnostic logs. Our servers write operational logs that can include the text of a conversation and the answers collected during it. People may read identifiable log content only with your explicit permission to inspect the specified session data, when necessary to investigate abuse or another security issue, or to comply with law. For ordinary troubleshooting, we explain which session data we want to inspect and why, and obtain your agreement before reading it. Aggregated and anonymised data may be used for internal operations. Logs are not backed up, and are deleted automatically within 7 days.

Why we process it

PurposeBasis
Running a voice session and filling in a formNecessary to provide the service you asked for
Using your microphoneYour permission, given in the browser and withdrawable at any time
Delivering responses to the CreatorOn the Creator’s instructions, as their processor
Keeping you signed inNecessary to provide the service
Troubleshooting a session by reading its logsYour explicit permission to inspect the specified session data
Investigating abuse and security issuesOur legitimate interest in a secure, non-abused service
Complying with legal requirementsOur legal obligations

We do not use this data for advertising, profiling, or automated decisions that produce legal or similarly significant effects about anyone.

Google user data

If you connect a Google account, we request only the following access. Each permission exists for one specific feature.

PermissionWhat it is used for
Name and basic profileRequested when you sign in with Google, to create your account and show your name.
Google Drive & SheetsCovers both file-upload storage and Google Sheets delivery. For each, AmphiVox works only inside the one Drive folder or the one spreadsheet you set for that form — one it creates for you, or an existing one you select with Google’s file picker.
Email addressShows which Google account is connected, so you can confirm you linked the right one.

Limited Use. AmphiVox’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Specifically: we do not transfer Google user data to third parties except as needed to provide or improve the features you have enabled, to comply with applicable law, or as part of a merger or acquisition. We do not use Google user data for advertising, and we do not allow humans to read it except with your explicit permission, for security purposes, to comply with applicable law, or where the data has been aggregated and anonymised.

If you connect Microsoft Excel instead, you give AmphiVox access to your Microsoft OneDrive. That access covers your files generally rather than a single workbook, but we only use it to create and write to the one workbook set as a form’s destination.

You can disconnect at any time from within AmphiVox, or revoke access directly at your Google account permissions page.

Who we share data with

We do not sell personal data and we do not share it for advertising. Data reaches the following service providers only so the product can function:

ProviderWhat it doesWhat it receives
GoogleSpeech recognition and speech synthesis, the AI that runs the conversation, reading uploaded form images, database and account sign-in, and delivery into your own Drive or SheetsLive session audio, transcribed text, collected answers, uploaded files, and all stored data described in this policy
Sarvam AISpeech recognition and speech synthesis for Indian languages, and transcribing a feedback note you choose to dictateLive session audio, assistant response text, and a dictated feedback recording (transcribed once, never stored)
OpenAISpeech recognition, the AI that runs the conversation, and speech synthesis, for voice sessions that use the Express modeLive session audio, the assistant’s replies, your answers, and the values on the form while a session runs
MicrosoftDelivering responses into your own Excel workbookResponse data
Fly.ioApplication hostingData in transit and short-lived diagnostic logs
DailyDelivers part of the software that sets up the live audio connection in your browserYour IP address, when that software is downloaded

Responses are also delivered to the destination the Creator chose — their own Google Sheet, Excel workbook, or Drive folder — and to the Creator themselves.

If a form offers a Google review

A Creator can add a link to their Google Business listing. If they have, the page you see after submitting offers that link to every respondent, and may show a short draft review written from your own answers for you to edit and copy. The draft is produced by Gemini from the answers you gave, excluding email, phone, address, link, file and consent fields, and any field the Creator marked as personal. A name is left out only if the Creator marked that field as personal. Neither the draft nor anything you edit is stored by AmphiVox. Nothing is posted anywhere by us: following the link takes you to Google, and what you write there is governed by Google’s own policies, not this one.

We may disclose data where the law requires it, or to protect the rights and safety of users and the public.

How long we keep data

DataKept for
Voice recordingsNot kept — discarded as the session runs
A dictated feedback note (the audio)Not kept — transcribed once, then discarded
Answers collected during a sessionHeld in memory only; discarded when the session ends
Session technical data (connection identifiers and timings)14 days, then deleted automatically
Diagnostic logs (may contain conversation text)Up to 7 days, then deleted automatically; not backed up
Submitted responses stored in AmphiVoxUntil the Creator deletes the form they belong to. We do not currently impose an automatic time limit.
Creator account detailsUntil the account is deleted
The record that a signed-in respondent answered a form (account id, email, the form, and when)Until the Creator deletes that form. We do not currently impose an automatic time limit.
Connected account credentialsUntil you remove the connection or delete your account
The email address of a connected accountUntil you remove the connection or delete your account
Feedback you leave after a voice session365 days, including after your account is deleted
Device identifier record (see section 10)30 days on our servers for the introductory tip; 365 days where it labels feedback left without signing in; the related cookie lasts 1 year

Responses delivered to a Creator’s own Google Sheet, Excel workbook or Drive folder are held in their account, under their control and their retention choices — not ours.

You can stop a form sending responses to Google or Microsoft at any time; the connection itself stays, so you can use it for other forms, until you remove it from Connections in your Account. When you remove a Google connection, we delete the credentials we stored and ask Google to revoke the permission, so it no longer works. When you delete your account, we do the same for every connection. Microsoft does not offer an equivalent way for us to revoke a single connection, so a Microsoft connection is deleted from our records but the permission itself is only fully removed if you also remove it from your Microsoft account.

We keep an internal usage record for each voice session (the form’s id and title, the owner’s account id, the session’s times and its processing cost) for our own accounting, even after the account or form is deleted. It contains no answers.

Your rights

Depending on where you live, you may have rights to access, correct, delete, restrict or object to the processing of your personal data, to withdraw consent, and to receive a copy of your data. You can also complain to your local data protection authority.

To exercise any of these, write to contactus@amphivox.com. We may need to verify who you are before acting. We aim to respond within 30 days.

Creators can delete an individual form at any time from within the product, which also deletes the responses, connected credentials and widget keys belonging to it. You can also delete your entire account yourself, at any time, from your Profile page — this immediately and permanently deletes your account, every form you own, and their stored responses, connected credentials and widget keys. Feedback you left, diagnostic logs, the usage record described in section 7, and the record that you answered someone else’s form are not deleted with it; they expire or remain as section 7 describes. If you can’t access your account, email us at the address above and we will action it for you.

If you were a Respondent, see section 1 — the Creator of the form controls your answers, so please contact them first.

Security

Measures currently in place:

  • All traffic to the service is encrypted in transit using HTTPS.
  • Submitted responses are encrypted before they are stored, using authenticated symmetric encryption (Fernet, AES-128-CBC with HMAC).
  • Credentials for connected Google and Microsoft accounts are encrypted before storage.
  • Sign-in tokens are held in HTTP-only cookies, which scripts on a page cannot read. The browser extension keeps its own connection token in the extension’s private storage, which web pages cannot read.
  • Voice sessions run in isolated processes with a hard duration limit.

No system is perfectly secure and we cannot guarantee absolute security. If you find a vulnerability, please report it to contactus@amphivox.com.

Cookies and local storage

These are all the cookies AmphiVox sets. There are no advertising cookies and no third-party analytics cookies. Most are strictly necessary to sign you in; the others only remember that you have already seen an introductory tip, or help us keep the voice service fair.

CookiePurposeTypeLifetime
Sign-in cookieKeeps you signed in, and renews itself while you keep using AmphiVox so you do not have to sign in againStrictly necessary3 days from your last visit
Sign-in state cookieHolds temporary state while you sign in with Google, and is removed when sign-in completesStrictly necessaryUntil sign-in completes, or 14 days if you abandon it
Preference cookieRemembers that you have already seen the one-time introductory tipConvenience1 year
Usage cookieHelps us keep the voice service fair and available for everyoneConvenience13 months

We also use your browser’s storage to save form drafts (your answers, for up to 24 hours) so you can resume if you navigate away, to hold a response briefly while you sign in again, and for small interface preferences.

Device identifier. To avoid showing the same one-time introductory tip repeatedly, and to label feedback left without signing in, we generate an identifier from your browser’s characteristics. It contains nothing you typed, is not shared with anyone, and is not used to track you across other websites — but it is a persistent identifier for your browser rather than a truly anonymous one. The record we keep of it for that purpose expires after 30 days.

The same identifier has a second use. If you rate a voice session without being signed in, we attach it to that rating, so that ratings left from the same browser can be told apart. It is stored with the rating and any note you add, and kept for 365 days. If you are signed in, we store your email address with the rating instead, and not the identifier.

Some voice modes have usage limits. To apply them fairly, we may use the same identifier together with the cookie above. It is not used to track you across other websites.

Artificial intelligence

When you use a voice form, you are talking to an AI system, not a person. It listens to your answers, decides which field each answer belongs to, and asks follow-up questions.

Speech recognition and AI interpretation make mistakes. You can review every answer on screen and correct anything that was misheard. On an AmphiVox form the assistant asks you before it finishes. If you agree, every answer is valid, and the form has no field you must fill in by hand (a file upload, a link, a consent box, or a field its Creator marked as personal), the form is then submitted for you. Otherwise you press Submit yourself.

The AI does not make decisions about you that have legal or similarly significant effects. It only fills in a form.

Is what I say used to train AI models?

No. AmphiVox does not train, fine-tune or improve any AI model using your speech, your answers, or anything else you send us. We do not build AI models at all. The providers we pass data to are committed to the same under the terms that apply to our account:

ProviderWhat their terms give you
Google — Gemini, the AI that runs the conversation, reads any form image a Creator uploads, and writes the optional review draft described in section 6We use it on a billed account, which makes it a paid service under Google’s terms. Google does not use what we send, or what it sends back, to improve its products or train its models. It keeps a copy for a limited period — up to 55 days — solely to detect abuse and policy violations.
Google Cloud — speech recognition and speech synthesisAudio and transcripts are not logged at all by default. The optional programme that would let Google use them to improve the service is opt-in, and we have not enabled it. Google’s cloud terms separately commit it not to train AI models on customer data without permission.
Sarvam AI — speech recognition and synthesis for Indian languages, and transcription of a dictated feedback noteSarvam lets each customer switch off the use of their content for training. We have switched it off on our account, so what you say is not used to train Sarvam’s models.
OpenAI — speech recognition, the AI that runs the conversation, and speech synthesis in Express modeOpenAI does not use what is sent through its API to train or improve its models unless the customer opts in, and we have not. It keeps a copy for up to 30 days solely to detect abuse.

Those are the providers’ own commitments, checked on 28 October 2026. We do not control their terms and they can change them. If a change affects what happens to your data, we will update this policy.

The short-lived copies described above are held by those providers for security purposes, under their own policies. They are separate from the diagnostic logs on our own servers described in section 3, which we delete after 7 days.

Voice and biometric data

We do not create voiceprints and we do not identify anyone by their voice. Your speech is used for one purpose only: understanding what you said so it can be placed in the right field.

We do not use voice to authenticate or verify identity, we do not attempt to detect emotion, and we do not categorise people by voice characteristics.

Children

AmphiVox is not intended for anyone under 18, and we do not knowingly collect their data. If you believe a child has provided data to us, contact contactus@amphivox.com and we will delete it.

Creators are responsible for not directing forms at children without a proper legal basis and any parental consent their local law requires.

Changes and how to contact us

We may update this policy. The “last updated” date at the top always reflects the current version. If we make a significant change we will make that clear on this page.

For any privacy question, request or complaint, email contactus@amphivox.com.
