Terms of Service

Last updated: August 18, 2025

Agreement to Terms

These Terms govern your access to and use of Echo (the "Service") provided by Echo Ltd ("Echo", "we", "us"). By using the Service, you agree to these Terms.

Description of Service

Echo provides tools for scheduled messaging, AI drafting/summarization, and search over user-provided content. Echo is not affiliated with WhatsApp or Meta.

Accounts & Eligibility

You must provide accurate information and keep it updated.
You are responsible for maintaining the security of your account and devices.

Your Content & License

You retain ownership of your content. You grant Echo a worldwide, non-exclusive, royalty-free license to host, process, and display it solely to provide and improve the Service.

Acceptable Use

No unlawful, harmful, infringing, or spam activity.
Obtain required consents for messaging recipients and comply with privacy laws.
No reverse engineering, bypassing security, or abusing rate limits.
No use in life-critical or high-risk scenarios.

Third-Party Dependencies & Delivery

The Service depends on third-party networks and providers (including WhatsApp, device availability, AI vendors). We do not guarantee uninterrupted service or delivery times. Scheduled messages may be delayed, duplicated, or not delivered. Scheduled messages include a brief automatic retry window; if delivery still fails, Echo will notify you and require manual resend.

Scheduled Messaging & Retries

At the scheduled time Echo attempts immediate delivery. If delivery fails due to a transient condition (e.g., device offline, network hiccup, temporary provider error), Echo performs a fast automatic retry within a short retry window. If delivery still fails, the message is marked Action Required and you are notified so you can manually send or reschedule.

Fast retry: a limited burst of automatic retries shortly after the scheduled time.
Failure notification: in-app alert (and email/WhatsApp if configured) with the failed item highlighted.
Manual control: Echo does not continue attempting indefinitely; you can resend, edit, or delete.
Limits: Delivery may still fail due to platform restrictions, device state, or provider outages. See the sections “Third-Party Dependencies & Delivery” and “Limitation of Liability”.

Scheduled messaging is not intended for life-critical or high-risk scenarios. For time-sensitive events, keep a manual fallback.

Service Levels

The Service is provided on a best-effort basis and “as is”. Unless a separate signed SLA applies, no uptime or delivery guarantees are offered.

Fees, Billing, Refunds

Fees are charged per the plan you select. Taxes may apply.
Except as required by law, payments are non-refundable. Credits may be issued at our discretion.
Plans may include usage limits or fair-use thresholds.

Changes

We may modify features. Continued use after changes constitutes acceptance.

Termination

You may stop using the Service at any time.
We may suspend or terminate access for breach, risk, or legal compliance.
Upon termination, we will delete or de-identify your content per our Privacy Policy.

Disclaimers

The Service is provided “AS IS” and “AS AVAILABLE”, without warranties of any kind. We do not warrant delivery times or error-free operation.

Limitation of Liability

To the maximum extent permitted by law, Echo and its team will not be liable for indirect, incidental, or consequential damages. Our total liability will not exceed the greater of (a) fees paid in the last 3 months or (b) $100.
