SMS Gateway API

Terms of Service

Last updated: April 2026

These Terms of Service ("Terms") govern your use of the SMS Gateway API Android application ("App") developed by SimpApp. By using the App, you agree to these Terms.

1. Description of Service

SMS Gateway API allows you to use your Android device as an SMS gateway — sending SMS messages programmatically via API commands and optionally forwarding received SMS to a webhook you configure. The App also optionally supports RCS (Rich Communication Services) message detection when you grant Notification Access permission in Android Settings. The App is a developer/automation tool, not a default SMS handler.

2. Acceptable Use

You must comply with all applicable laws and your mobile carrier's terms regarding SMS usage.
You must not use the App to send spam, unsolicited commercial messages, or any content that violates applicable laws.
You are solely responsible for the SMS messages sent through your device via this App.
You must obtain any necessary consent from recipients of SMS messages.

3. Account and Data

You may create an account using Google Sign-In. You can delete your account at any time from the App's Settings screen, which will permanently delete all associated data. See our Privacy Policy for details on what data we collect and how it is used.

4. Subscriptions and Billing

The App offers optional paid subscriptions (PRO Monthly, PRO Yearly) managed through Google Play Billing. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. You can manage or cancel subscriptions at any time in the Google Play Store.

5. No Warranty

The App is provided "as is" without warranties of any kind. SMS delivery depends on your carrier's network and is not guaranteed. We are not liable for failed or delayed SMS delivery.

6. Limitation of Liability

To the maximum extent permitted by law, SimpApp shall not be liable for any indirect, incidental, or consequential damages arising from your use of the App.

7. Changes to Terms

We may update these Terms from time to time. Continued use of the App after changes constitutes acceptance of the new Terms.
