01 Privacy Policy

Privacy Policy

Your privacy is fundamental to how STL Toolkit works. This policy explains how we handle your data—and why most of it never leaves your device.

No file uploads Local processing Minimal data collection

02 Overview

Privacy at a Glance

STL Toolkit is designed with privacy as a core principle. Unlike many online tools, we process your files entirely within your browser using modern web technologies.

This means your 3D models, images, and other files never leave your device. We cannot access, view, or store your files. This page explains what little data we do collect and how we protect it.

03 Core principles

Our Privacy Commitments

These aren't just words—they're built into how our tools work.

04 What this means

What We Don't Collect

No File Uploads

All file processing happens locally in your browser. Your files never leave your device.

No Account Required

Use our tools without creating an account or providing personal information.

No Tracking

We don't track your file names, contents, or usage patterns beyond basic analytics.

Local Storage Only

Any data you enter stays in your browser's local storage and is never transmitted.

05 Data handling

What Data We Collect

We collect minimal data to maintain and improve our services:

Analytics Data: We use privacy-focused analytics that track page views and basic usage patterns without identifying individuals. This helps us understand which tools are most popular and where users encounter issues.

Technical Data: Basic server logs may record IP addresses, browser types, and request times for security and debugging purposes. These logs are automatically deleted after 30 days.

No Personal Information: We don't require accounts, so we don't collect names, emails, or other personal identifiers unless you voluntarily provide them (e.g., when contacting us).

No File Data: Your STL files, images, and other documents are processed locally and never transmitted to our servers. We have no access to your file contents.

06 Technical implementation

How Privacy Works Technically

Our privacy approach is built into how the tools work:

Local Processing
All file operations run directly in your browser—nothing is sent to a server.
No Server Uploads
Files are read from your device, processed locally, and saved back to your device.
Secure Storage
Any data stored stays in your browser and is never synchronized to external servers.

This means even we couldn't access your files if we wanted to—the processing happens entirely on your device.

07 Cookies & storage

Cookie Policy

STL Toolkit uses minimal cookies and local storage:

Essential Cookies: We use only essential cookies required for the website to function. These don't track you and are necessary for basic operations.

Local Storage: Your browser's local storage may be used to remember your preferences (like theme settings) and to cache tool assets for faster loading. This data stays on your device.

No Third-Party Tracking: We don't use advertising cookies, social media trackers, or any third-party scripts that profile users.

You can clear local storage at any time through your browser settings without affecting the functionality of our tools.

08 Your rights

Your Privacy Rights

Depending on your location, you may have certain rights regarding your personal data:

Access: You can request information about what data we have about you.

Deletion: You can request deletion of any personal data we hold.

Portability: You can request a copy of your data in a machine-readable format.

Objection: You can object to processing of your personal data for certain purposes.
