EchoFour Terms of Service

Last updated: 27 June 2026

EchoFour is an internal tool provided by TwoFour to its own employees for recording, transcribing, and summarizing work meetings. By using EchoFour you agree to these terms. If you do not agree, do not use the app.

Internal use only. EchoFour is not a public or commercial product. Access is limited to authorized TwoFour employees signing in with a company Google account.

1. Eligibility & accounts

You must be a current TwoFour employee (or otherwise authorized by TwoFour) and sign in with an allow-listed company Google account.
You are responsible for activity under your account and for keeping your sign-in credentials secure.
Access may be suspended or revoked at any time, for example when your employment or authorization ends.

2. Acceptable use

When using EchoFour you agree to:

Use it only for legitimate TwoFour business purposes.
Record meetings only where you have the necessary consent of participants and comply with applicable laws and company policy on recording.
Not upload unlawful content, malware, or content you have no right to share.
Not attempt to break, probe, or circumvent the app's security, encryption, or access controls, or use it to access data that is not yours.
Follow TwoFour's internal IT, security, and acceptable-use policies, which also apply.

3. Your content

You retain ownership of the meeting audio, transcripts, and summaries associated with your account ("your content").
You grant TwoFour permission to process your content solely to provide the service (transcription, summarization, storage, and notifications), as described in the Privacy Policy.
Transcripts and summaries are end-to-end encrypted and readable only on your device. You are responsible for safeguarding your passphrase and recovery code.

4. Encryption & data loss

EchoFour uses zero-knowledge end-to-end encryption for transcript and summary content. This means TwoFour cannot recover your encrypted content if you lose both your passphrase and your recovery code. There is no administrator override. You accept this risk as a condition of the privacy guarantee the encryption provides.

5. Availability

EchoFour is provided on an "as is" and "as available" basis for internal use. We may change, suspend, or discontinue any part of the service, perform maintenance, or modify features at any time without notice. We do not guarantee uninterrupted or error-free operation.

6. Third-party services

EchoFour relies on third-party providers (for example Google sign-in and calendar, speech-to-text, language-model summarization, hosting, push notifications, and email). Your use of those underlying features is also subject to the respective providers' terms. See the Privacy Policy for details on data sharing.

7. Disclaimers

Automated transcripts and summaries may contain errors or omissions. Do not rely on them as a complete or verbatim record without review.
To the maximum extent permitted by law, the service is provided without warranties of any kind, express or implied.

8. Limitation of liability

To the maximum extent permitted by law, TwoFour is not liable for any indirect, incidental, or consequential damages, or for loss of data, arising from your use of (or inability to use) EchoFour. Because EchoFour is an internal benefit provided to employees, your use is at your own discretion and subject to company policy.

9. Changes to these terms

We may update these terms as the product evolves. Material changes will be communicated internally and reflected by the "last updated" date above. Continued use after a change means you accept the updated terms.
