Last updated: September 26, 2026

1. Introduction

Welcome to Mystery Message. By using our services, you agree to these terms. Please read them carefully.

2. Using Our Services

Follow our policies while using the Services. We may suspend your access if you violate these terms.

3. Privacy and Content

Our Privacy Policy outlines how we handle your data. You agree to our use of your data as per this policy.

Content displayed is the responsibility of the provider. We may remove content that violates our policies.

4. Acceptable Use

Mystery Message is built for respectful and fun anonymous messaging. You may share honest feedback, compliments, questions, and lighthearted notes — not harm.

Prohibited actions include:

  1. Vulgar, obscene, or sexually explicit messages
  2. Abusive, harassing, hateful, or threatening language
  3. Using slang or native-language slurs intended to insult or degrade someone
  4. Sending harmful, exploitative, or illegal content
  5. Interfering with service performance
  6. Attempting unauthorized access
  7. Reproducing or reselling our services

We use server-side content moderation to reject messages that violate these rules before they are delivered. Rejected messages are not saved to the recipient's inbox and do not trigger notifications. Repeated violations may lead to temporary restrictions or account action.

5. Modifying and Terminating our Services

We may change or stop our services at any time. You can stop using our services whenever you choose.

6. Disclaimers

Our services are provided "AS IS" without warranties. We disclaim all implied warranties.

7. Changes to These Terms

We may modify these terms to reflect changes in law or services. Check back regularly for updates.

8. Child Safety and Protection Policy

Mystery Message is committed to protecting children and preventing any form of child sexual abuse material (CSAM) or exploitation. We strictly prohibit the creation, sharing, or storage of any content involving minors in a sexual or harmful context.


We actively monitor and remove any content that violates these standards and cooperate with relevant authorities when required. Users can report inappropriate or harmful content directly within the app or by contacting us through our Contact Page.


Mystery Message complies with all applicable child protection laws and Google Play's child safety standards. For more information, please visit our Child Safety Standards page.

9. Anonymous Messaging, Security Processing, and Sender Hints

Sending an anonymous message does not mean Mystery Message processes no technical information. To operate the service, prevent abuse, and meet safety obligations, we may process IP and network information server-side and derive an approximate location from that information.

If you are an eligible PRO MAX recipient, certain sender properties may be shown to you as Sender Hints. Those hints are estimates based on network data. They do not identify a sender with certainty, do not reveal an exact house or street location, and do not include a raw IP address.

Mystery Message may retain security information associated with messages for abuse prevention and lawful safety requirements. Sender Hints are a premium estimate feature, not a guarantee of identity.
