Privacy Policy
ReplyLingo values your privacy. This policy explains exactly what data we process, who receives it, why, how long it is kept and how you can delete it or withdraw AI-processing consent.
Introduction
ReplyLingo values your privacy.
ReplyLingo helps users translate voice messages using AI while keeping user privacy and security a priority.
ReplyLingo relies on third-party AI providers — OpenAI and ElevenLabs — to deliver its core translation features. The sections below describe that processing in detail.
AI processing in short
When you use ReplyLingo's translation features, your voice recordings, shared audio, transcripts and translation text may be sent over a secure connection to OpenAI (speech-to-text and AI translation) and ElevenLabs (text-to-speech). This data leaves your device only to perform the translation you requested.
1. Information We Collect — Voice and Audio Data
ReplyLingo may process the following audio, and only because you explicitly use the app's voice and translation functionality:
- Voice recordings you make with your device microphone inside ReplyLingo
- Audio files you share into ReplyLingo from another application
- Audio you submit for translation
- Audio used to generate or provide a translated response
ReplyLingo does not record audio in the background or without your action.
Transcribed Text
Voice recordings and shared audio may be converted into text through speech-to-text processing so that the message can be read and translated.
Translation Text
Transcribed text, or text you type yourself, may be processed to translate the message into the language you select.
Generated Audio
When you request a spoken translation or voice reply, translated text may be converted into spoken audio and returned to you inside the app.
Account Information
Users may sign in using:
- Apple Sign In
- Google Sign In
- Continue as Guest
When signing in with Apple or Google we may receive:
- Name
- Email Address
- Authentication Identifier
An account is not required to use ReplyLingo — Guest mode works without creating one.
Conversation History
Conversation history — including your messages, transcripts, translations and related audio references — is stored locally on your own device using AsyncStorage.
ReplyLingo does not maintain a server-side copy of your conversation history. Audio, transcripts and translations are transmitted to the AI providers listed below only while a translation request is being performed.
2. How We Collect Information
Microphone recordings
When you record your voice in ReplyLingo, the app accesses the microphone and processes that recording to provide speech-to-text, translation and/or spoken output. Microphone access is requested through your operating system and can be revoked in your device settings at any time.
Shared audio
When you share audio into ReplyLingo from another application, ReplyLingo processes that audio to provide the translation you requested.
User-entered information
Text you type into ReplyLingo, and the language settings you choose, are processed to provide translation and related functionality.
Conversation history
History entries are created on your device as you use the app and are written to local device storage (AsyncStorage). They are not uploaded to a ReplyLingo server.
3. Third-Party AI Processing
ReplyLingo uses third-party AI services to provide its voice translation functionality. The providers are named explicitly below.
OpenAI
ReplyLingo sends voice recordings and/or their transcripts to OpenAI when necessary to provide speech-to-text and AI-powered translation. This processing allows ReplyLingo to convert spoken messages into text and translate them into the language you selected. Data is sent only when you trigger a translation or transcription; no data is sent to OpenAI when the app is idle.
ElevenLabs
ReplyLingo may send translated text to ElevenLabs to generate spoken audio when you request an audio translation or spoken reply. ElevenLabs receives the text needed to synthesise that speech; it is not used for any other purpose.
Each provider processes the data only to return the result of your request. Their own handling of data is governed by their respective privacy policies and the terms under which ReplyLingo accesses their APIs.
Provider transparency
| Provider | Purpose | Data that may be sent |
|---|---|---|
| OpenAI | Speech-to-text and AI translation | Voice recordings and/or transcripts and translation text, as required for the requested feature |
| ElevenLabs | Text-to-speech | Translated text used to generate spoken audio |
4. Data Flow
- 1You record audio with the microphone, share audio into ReplyLingo, or type text.
- 2The audio is prepared for speech recognition and sent to OpenAI for transcription.
- 3The resulting text may be sent to OpenAI for translation into your selected language.
- 4When spoken output is requested, the translated text may be sent to ElevenLabs to generate audio.
- 5ReplyLingo returns the translated text and/or generated audio to you in the app.
- 6The result, along with your conversation entry, is stored locally on your device. ReplyLingo does not keep a server-side copy of the audio, transcript, translation or generated audio.
5. Purpose of Processing
Your data is processed only to:
- Convert spoken language into text
- Translate messages between languages
- Generate spoken translations and replies
- Provide the core ReplyLingo voice translation functionality
- Maintain your conversation history on your device
Your conversations are never used for advertising, profiling or any unrelated purpose.
6. Data Retention
- Original voice recordings and shared audio: kept on your device as part of your conversation history; not retained on a ReplyLingo server.
- Transcripts, translations and generated audio: kept on your device as part of your conversation history; not retained on a ReplyLingo server.
- Data sent to OpenAI and ElevenLabs: transmitted only for the duration of the request needed to return your result, and retained by ReplyLingo only for as long as necessary to provide the requested functionality.
- Account information (name, email, authentication identifier from Apple or Google sign in): retained while your account exists, and deleted when you request account deletion.
Locally stored data remains on your device until you delete it, clear the app's data, or uninstall the app. ReplyLingo does not apply a fixed expiry period to data stored on your device.
7. Data Deletion
- Conversation history, audio, transcripts and translations: delete your history from inside the ReplyLingo app, or clear the app's data / uninstall the app to remove all locally stored content.
- Account information: email johnny90566@gmail.com to request deletion of your account, authentication data and support correspondence.
Because ReplyLingo does not retain your audio, transcripts or translations on a server, there is no server-side conversation data for us to delete. Data processed by OpenAI or ElevenLabs as part of fulfilling a request is handled under their own policies and is outside ReplyLingo's direct control; we cannot promise deletion of information we do not hold.
8. AI Processing Consent
ReplyLingo's translation features cannot work without AI processing. By using the recording, sharing or translation features you are informed that your voice, audio and text may be sent to OpenAI and ElevenLabs, as described above, for the sole purpose of producing the translation or spoken output you requested.
You control this at all times: no audio or text is sent to any AI provider unless you start a translation. You can also revoke ReplyLingo's microphone permission in your device settings, or stop using the AI features, at any time.
9. Effect of Withdrawing Consent
If you withdraw consent for AI processing, ReplyLingo will no longer send your voice, audio or text to the applicable AI providers. Features that depend on AI processing, including transcription, translation and voice generation, will be unavailable until consent is provided again. Conversation history already stored on your device is not affected and can be deleted separately.
