What This Page Covers

We're being straight with you about how persistx.com tracks visitor behavior. There's no fine print hiding what we collect or why. This document walks through the technical side of web tracking and gives you actual control over what happens with your browsing data.

Our platform uses various tracking methods. Some are essential for the site to work at all. Others help us understand how people interact with our 3D environment tools and content. A few are used for promotional purposes. You get to decide which ones stay active.

Essential Tracking Technologies

These are the ones we can't turn off. Without them, persistx.com wouldn't function properly. They handle session management, security verification, and basic user preferences.

We don't sell this data. We don't share it with third parties. It exists solely to make the site work the way you expect it to.

Functional Tracking

These enhance your experience but aren't strictly necessary. They remember your project preferences, favorite tools, and interface customizations.

What Gets Tracked

• 3D viewport settings and camera positions you've saved
• Frequently used tools and shortcuts
• Tutorial progress and bookmark positions
• Interface layout preferences

This data stays on your device until you clear it manually or reject non-essential tracking. It makes returning to your projects smoother, but the site works fine without it.

Analytical Tracking

Here's where we learn what's working and what's confusing people. We track page views, time spent on different sections, and which features get used most often.

Specific Metrics We Collect

• Which tutorial sections cause people to leave the site
• How long it takes users to complete specific tasks
• Error messages that appear during tool usage
• Browser and device information for compatibility testing
• Geographic region (country level only, not precise location)

We use Google Analytics for this. They have their own data retention policies. When you decline tracking, we send a signal to Google telling them not to collect your data. This uses Google Consent Mode v2, which is their current standard as of 2025.

Marketing Tracking

This is the controversial stuff. We use tracking pixels to show you relevant content and measure whether our educational materials are reaching the right audience.

Third parties involved: Google Ads, Meta Pixel. Both have their own privacy policies and data retention schedules. When you decline tracking, we disable these pixels for your session.

Data Retention Schedule

Different types of data stick around for different lengths of time. Here's the actual breakdown:

• Essential session data: Deleted when you close your browser or after 2 hours of inactivity
• Functional preferences: Stored locally until you manually clear them or decline tracking
• Analytical data: Aggregated after 14 months, individual identifiers removed after 26 months
• Marketing pixels: Expire after 90 days or when you decline tracking, whichever comes first

You can request complete deletion of your data by emailing help@persistx.com. We'll process it within 7 business days and send confirmation.

Technical Details for Developers

If you're technically inclined and want to verify what we're doing, here are the specifics:

Cookie Names and Purposes

• pxs_session - Session identifier, HttpOnly flag set, Secure flag set, SameSite=Strict
• pxs_csrf - CSRF token, rotates every 15 minutes, expires with session
• pxs_prefs - User preferences, stored as JSON, client-side only
• _ga - Google Analytics identifier, 2-year expiration, can be blocked
• _fbp - Facebook Pixel, 90-day expiration, only loads if marketing accepted

All tracking scripts load asynchronously and won't block page rendering. If you decline tracking, we set a localStorage flag that prevents scripts from initializing at all.
