Privacy Policy

Effective: February 16, 2026 · Z-Text Ltd

Introduction

Z-Text is built on the principle of minimal data collection. We do not track users, set cookies, or use analytics services. This policy explains exactly what data we handle and why.

What We Don't Collect

We deliberately avoid collecting the vast majority of data that other services routinely gather. Specifically, we do not collect:

  • Cookies or session tokens
  • IP addresses (beyond temporary rate limiting)
  • Browser fingerprints or device identifiers
  • Analytics or usage telemetry
  • Third-party tracking scripts or pixels
  • Personal identity information — no name, email, or phone number

What We Store

For time-limited subscriptions, we store: your z-address (fully anonymous — not linked to any identity), payment amount, cryptocurrency type, license status, and expiration date. This data is used solely for payment processing and license verification.

Lifetime licenses are free of all data storage. Lifetime packages accept Zcash (ZEC) payments via shielded z-addresses — making the payment completely untraceable. Once your signed receipt is delivered on-chain, all subscription details are deleted immediately. Your delivery BitcoinZ z-address is retained for 24 hours only (in case receipt delivery needs to be retried), then auto-deleted. After 24 hours, we hold zero data about your purchase.

Blockchain Data

Messages sent through Z-Text are shielded transactions on the BitcoinZ blockchain. We cannot read, access, or monitor message content. The password vault is encrypted locally and stored on-chain — we have no access to vault data.

Third-Party Payment Processing

Payments are processed through OxaPay. Their processing is limited to payment confirmation — no personal data is shared with them.

Rate Limiting

We use IP-based rate limiting to prevent abuse. IP addresses are held in memory temporarily and are never stored persistently or logged.

Data Retention

Payment records (z-address, amount, license status) are retained for the duration of your license. We do not sell, share, or transfer any data to third parties.

No Tracking on This Website

This website does not use cookies, analytics scripts, or tracking pixels. No behavioral data is collected.
