Privacy Policy

01.Introduction

Welcome to FreeTattooStencil.com ("we", "our", "us", or the "Service"). We provide an in-browser digital image conversion tool engineered specifically for tattoo artists, apprentices, studios, and illustrators to generate clean thermal stencils and printable templates.

This Privacy Policy describes how we handle information when you access or use our website. We believe that tattoo reference photos—which often feature deeply intimate client portraits, memorial imagery, or proprietary studio artwork—belong exclusively to you and your client. This document explains how our zero-upload architecture guarantees your data stays on your personal device.

02.Our Core Privacy Commitment: Zero Server Uploads

Unlike traditional cloud-based photo editors and AI software that transmit your files to remote servers for processing, FreeTattooStencil.com operates as a 100% client-side WebApplication:

• In-Memory Processing: When you drag and drop or select an image file (JPEG, PNG, WEBP), it is read directly into your device's browser memory via the HTML5 File API and Canvas API.
• Local Algorithmic Filtering: All image manipulations—including Difference of Gaussians (DoG) edge detection, Bilateral noise reduction, Bayer dithering, thresholding, thermal paper coloring, and manual canvas retouching—are executed directly by your computer or tablet's CPU/GPU via WebAssembly (OpenCV.js).
• No Backend Image Server: We do not operate an image processing backend. It is physically impossible for our servers to view, log, index, or store your photos because they are never sent over the internet to us.
• True-to-Size PDF Generation: PDF and PNG exports are generated locally in your browser sandbox using client-side JavaScript libraries (jsPDF) and downloaded directly to your local drive.

03.Information We Do NOT Collect

To eliminate any ambiguity, we explicitly state that we do not collect, harvest, or retain any of the following:

04.Information We May Process or Receive

We collect only the bare minimum technical data required to deliver a reliable, secure website:

• Standard Web Server Logs: Like virtually all websites, when you load a web page, our hosting web server may record automated technical requests, including IP address, browser user-agent, operating system, referring URL, and timestamp. These logs are used solely for network diagnosis, DDoS mitigation, and server reliability.
• Direct Communications: If you send us an email at hello@freetattoostencil.com, we receive your email address, your name (if provided), and the content of your message so we can assist you.

05.Cookies and Local Storage

We do not use intrusive cross-site tracking cookies, behavioral tracking pixels, or third-party data broker beacons.

Browser Local Storage: We may use your browser's native localStorage or sessionStorage to remember non-identifying operational preferences—such as your preferred default line thickness, measurement unit (inches vs. centimeters), or paper orientation (portrait vs. landscape). This data never leaves your browser and can be wiped at any time by clearing your browser cache.

06.Third-Party Assets & Content Delivery Networks (CDNs)

To provide fast global loading and reliable computer vision algorithms, our website loads static open-source assets from reputable content delivery networks:

• OpenCV.js CDN: We load the pre-compiled WebAssembly build of OpenCV (opencv.js) from the official OpenCV repository CDN. This is an open-source library that executes mathematical computer vision algorithms locally in your browser.
• Google Fonts: We serve typography (Inter font family) via Google Fonts. Google's font servers may collect standard HTTP headers to deliver the font files efficiently.

07.Data Retention and Discard Policy

Because we do not upload or store user images on our servers, our retention period for your artwork is zero seconds.

When you navigate away from FreeTattooStencil.com, close the browser tab, or refresh the page, all active image buffers in RAM and Canvas memory are immediately deallocated and garbage-collected by your browser engine.

08.International Compliance (GDPR, CCPA / CPRA)

We respect the privacy rights of visitors globally, including individuals in the European Economic Area (EEA), United Kingdom, California, and other jurisdictions:

• GDPR (General Data Protection Regulation): Our client-side architecture enforces "Data Protection by Design and by Default" (Article 25). We do not act as a data processor for your images because no data processing occurs on our systems. For email inquiries, you have the right to request access to or deletion of your email records.
• CCPA / CPRA (California Consumer Privacy Act): We do not sell, rent, or share personal information with third parties for commercial monetary or behavioral advertising purposes ("Do Not Sell or Share My Personal Info").

09.Children's Privacy

FreeTattooStencil.com is designed for professional tattoo artists, apprentices, designers, and adult enthusiasts. We do not knowingly solicit or collect personal information from individuals under the age of 13. If you believe a child has provided us with personal contact information, please contact us immediately so we can remove it.

10.Changes to this Policy

We may periodically update this Privacy Policy to reflect technical improvements, new browser capabilities, or legal requirements. When updates occur, we will revise the "Last Updated" date at the top of this page. Your continued use of the website following any update constitutes your acknowledgment of the revised terms.
