This privacy policy explains how the InTruth Firefox extension handles data.

InTruth is an experimental real-time fact-checking extension. It captures audio from the active browser tab, transcribes speech, analyzes the resulting text with a user-configured language model, and displays possible factual claims and verdicts.


InTruth does not operate its own remote server.

However, the extension can send data to third-party services selected or configured by the user, including:

• Deepgram, for audio transcription;
• an LLM provider, such as Anthropic, OpenAI, LM Studio, or another OpenAI-compatible endpoint;
• a search provider, such as Serper, if web grounding is enabled.

Users should review the privacy policies of the third-party providers they configure.


Depending on configuration, the extension may handle:

• audio from the active tab;
• generated transcripts;
• short transcript chunks sent to the configured LLM;
• detected claims and verdicts;
• user-provided API keys;
• extension settings stored locally in the browser.

When fact-checking is started, audio from the active browser tab may be streamed to Deepgram for transcription.

The extension does not send audio to the developer of InTruth.

Audio handling is performed by the transcription provider configured in the extension.


The transcript generated from the audio may be sent to the configured LLM provider so that the model can detect factual claims and produce verdicts.

The transcript may contain spoken content from the video, livestream, interview, debate, or page being analyzed.


Users enter their own API keys in the extension.

These keys may include:

• Deepgram API key;
• LLM provider API key;
• optional search provider API key.

API keys are stored locally using Firefox extension storage.

The developer of InTruth does not receive, collect, or store user API keys.


If search-based grounding is enabled, some detected claims or search queries derived from claims may be sent to a search provider.

This can include portions of the transcript or reformulated factual claims.


The extension may store locally:

• API keys entered by the user;
• provider settings;
• selected model name;
• endpoint URL;
• runtime status;
• recent error messages.

This information is stored in the user's browser.


The developer of InTruth does not intentionally collect:

• user browsing history;
• user API keys;
• audio recordings;
• transcripts;
• claims;
• verdicts;
• personal identifiers.

The extension is designed to run client-side in Firefox and to communicate only with the services required for transcription, LLM analysis, and optional search.


The extension may communicate with third-party services chosen by the user.

Examples include:

• Deepgram for speech-to-text;
• Anthropic or OpenAI for LLM analysis;
• LM Studio or a local endpoint for local model use;
• Serper for search results.

Each provider may process data according to its own terms and privacy policy.

Users are responsible for choosing which services they connect to the extension.


Do not use the extension on private, confidential, legally sensitive, medical, professional, or personal conversations unless you understand that audio or transcript text may be sent to third-party services.


The extension may request permissions such as:

• access to the active tab;
• scripting permission;
• storage permission;
• host permissions for configured API providers.

These permissions are used to capture tab audio, run the overlay, store settings, and communicate with external services required by the extension.


Users can stop fact-checking at any time from the extension popup.

Users can remove stored data by clearing the extension storage or removing the extension from Firefox.

Users can revoke API keys from the dashboards of the relevant third-party providers.


This privacy policy may be updated as the extension evolves.

When changes are made, the date at the top of this document should be updated.
