Privacy Policy

Last Updated: May 22, 2026. Review our commitments to transparent data minimization and high-risk SMS sync safety.

SMS Permission & Synchronization Scope

SMX requires the restricted Android permissions READ_SMS and RECEIVE_SMS strictly for its core value proposition: importing your latest 100 existing SMS messages and syncing new incoming messages from your personal Android device to your secure SMX web dashboard. Synchronization occurs directly and securely. No unrelated data is read or logged.

Collected Data Properties

To provide real-time message syncing, we collect and display: raw SMS message text strings, message timestamps, sender mobile numbers, and sender contact names (if saved on the device). In addition, your registration verified email and chosen display name are securely saved to manage your personal dashboard account.

Strict FIFO Retention Limits (100 Message Max)

We believe in data minimization. SMX implements a strict First-In-First-Out (FIFO) buffer that retains a maximum of 100 messages per connected device in our database. Once this limit is reached, any older synchronized messages are permanently and irreversibly purged from our systems automatically.

Absolute Zero Third-Party Sharing

Your messages are yours alone. SMX does NOT sell, rent, lease, or share your message content, contact info, or metadata with any third parties, advertising networks, tracking suites, or search engines. There are no tracking scripts, advertising blocks, or analytical trackers embedded in our apps.

TLS 1.3 Secure Transport & Database Encryption

All communication between the SMX Android Client and the SMX Cloud Server is fully encrypted using TLS 1.3 pathways. Stored user details and synced texts are housed in secure production databases protected by standard firewalls and strict access credentials.

Instant Account & Data Wiping

We put you in control. Users can permanently and immediately delete their account and wipe all synced device profiles, synced messages, and registration details at any time with a single click inside the Web Client Settings menu. Wiping is instantaneous and complete.
