Privacy Policy

Last Updated: February 2026

1. Zero Data Transmission

SLTD - WA Sender is built on a **local-first architecture**. We do not collect, store, or transmit your personal messages, chat history, or contact lists to any external servers.

All processing of phone numbers and message content happens strictly within your browser's isolated environment.

2. Local Storage & Encryption

Your campaign data, including imported Excel/CSV files and personalized message templates, is saved locally using **Chrome's encrypted storage** and **IndexedDB**.

  • No database storage on our end
  • No access to your WhatsApp authentication tokens
  • Data persists only on your machine

3. License Validation

The extension communicates with our license server (wa.chatsimplified.co) solely to:

  • Verify your unique license key.
  • Verify the hardware ID of your device (device-locking).
  • Update your total message usage count for quota management.

We never transmit the content of the messages or the phone numbers being contacted during this process.

4. Permissions Usage

The extension requests only the minimum necessary permissions:

Host Permissions Required to interact with web.whatsapp.com natively.
Storage Required to save your campaign progress locally.
