TeeTransformer – AI T-Shirt Design Tool (Chrome Extension)
Last Updated: August 10, 2026 | Applies to extension version: 1.0.41+
Chrome Web Store Compliance: This extension complies with the Chrome Web Store User Data Policy. We collect only the minimum data necessary for the extension to function. We do not sell, rent, or share your personal data with third parties for marketing purposes. Images are sent to an AI provider only when you start a redesign or related job.
1. Overview
TeeTransformer is a Chrome browser extension that helps users redesign T-shirt graphics using AI. Depending on your settings, processing may use:
ChatGPT / Custom GPT (browser-based redesign on chatgpt.com, when you enable GPT mode)
Google Gemini (when Gemini mode / Gemini runtime is active)
xAI Grok and/or FLUX/SD (BFL) when the corresponding shared runtime is active
Users can upload T-shirt images, capture selected images from a webpage using the right-click context menu, or use supported product-page controls (for example Amazon or TeePublic image actions), choose a variation level (30% light / 70% medium / 100% strong), generate redesigned artwork, optionally strip backgrounds, and download print-ready results.
This Privacy Policy explains what data we collect, how we use it, how long we retain it, and your rights. We are committed to protecting your privacy and being transparent about our data practices.
2. Data We Collect
We collect only the minimum data necessary to provide our services:
Email Address: Used for optional account creation and authentication.
User ID: A unique identifier generated for your account.
Usage Statistics and Event Logs: Number of AI processing jobs performed, quota usage, and account events such as signup, login, and install.
Network and Device Information: IP address, country, city, and user agent, collected for security, fraud prevention, abuse detection, and account activity logs.
Uploaded / Selected Images: T-shirt or product design images you upload, import through right-click, or select through supported product-page controls for AI processing. These are sent to the provider you selected (ChatGPT, Google Gemini, xAI Grok, or FLUX/SD) only when you start a job, and are not permanently stored on our servers.
Generated and Downloaded Outputs: Redesign results, stripped-background PNGs, and product/design images you explicitly download. These files are handled locally in your browser and saved only when you click a Download action.
Redesign Settings (local): Redesign source choice (GPT Mode vs Gemini), Custom GPT URL and prompt preferences, mode, duplicate-image checks, dashboard history, and variation level (30% / 70% / 100%). Stored in your browser.
AI API Key (optional): If you provide your own Gemini, Grok, or FLUX/SD API key, it is stored locally in your browser only and never transmitted to our servers.
Payment Information: Processed through PayPal and PayOS. We do not store credit card details.
We do NOT collect: full browsing history, advertising profiles, passwords from other websites, or content from pages you visit except the design image you explicitly select for TeeTransformer.
3. How We Use Your Data
Authentication: Verify your identity and manage your account via Supabase.
AI Processing: Send your selected images (and the redesign prompt, including variation level) to the selected AI path — ChatGPT/Custom GPT, Google Gemini, xAI Grok, or FLUX/SD — to perform T-shirt artwork extraction, redesign, enhancement, and related steps you request.
Image Import and Download: Load a selected webpage image into the extension dashboard and download selected product/design images or processed pipeline outputs when you click a Download action.
Quota Management: Track your AI job usage and remaining balance.
Payment Processing: Process credit purchases via PayPal (USD) and PayOS (VND).
Security: Detect and prevent fraud, abuse, and unauthorized access.
Account Activity Logging: Record signup, login, install, and related account activity events.
Customer Support: Respond to your inquiries and provide assistance.
Service Improvement: Analyze aggregate usage patterns to improve our features.
4. Image Processing, Downloads, and Storage
Important information about how your images are handled:
Local Storage First: Design pipeline rows, recent imported images, duplicate checks, and results are stored locally in your browser’s chrome.storage.local. They are not uploaded to our servers for permanent storage.
AI Processing Only on Your Action: When you click Redesign (or related actions), your selected image is sent to the AI path you configured. This is the only time your image leaves your device for AI processing.
ChatGPT path: If GPT Mode is enabled, the extension may open or use a ChatGPT tab to process the image with your redesign prompt. Processing uses your ChatGPT session under OpenAI’s terms for that service.
API path: If Gemini (or another runtime) is enabled, the image is sent to that provider’s API over HTTPS. Gemini API redesign is disabled while GPT Mode is enabled.
Downloads: The extension may save product/design images, redesigned outputs, or stripped-background PNGs to your computer only after you click a Download button. It does not perform automatic background downloads or download unrelated files.
Product-page Controls: On supported product pages, such as Amazon and TeePublic, the extension may add explicit image action buttons. Main product images may show Download / Redesign controls; related product cards may show Redesign only. Color swatches and selector thumbnails are excluded.
No Permanent Server Storage of Designs: We do not permanently store your design images on our servers.
No Marketing Share: Your images are never sold or shared for advertising. They are only sent to the AI provider needed for the job you started.
User Control: You can clear locally stored data by removing the extension or clearing Chrome extension storage.
5. Chrome Permissions Explained
TeeTransformer requests the following Chrome permissions. Each permission is used only for the stated purpose:
Permission
Why It's Needed
storage
Store design tasks, results, optional API keys, redesign source settings, Custom GPT preferences, duplicate checks, dashboard history, variation level, auth state, and preferences locally in your browser.
unlimitedStorage
T-shirt design images can be several MB each. Standard storage quota is insufficient for multiple high-resolution results, imported product images, stripped PNG outputs, and recent pipeline history in the dashboard.
activeTab
Access the current tab only when you explicitly activate the extension or right-click an image. Not used for passive monitoring.
contextMenus
Add the “Redesign with TeeTransformer” option and related image actions to the right-click menu. Only used for images you explicitly select.
tabs
Open, focus, or coordinate tabs for the redesign workflow—especially ChatGPT when GPT redesign mode is enabled—and return you to the extension dashboard after import or processing when appropriate. Not used to track unrelated browsing.
scripting
Inject limited helpers for user-started workflows: resolve selected images and add explicit controls on supported product pages, and support ChatGPT redesign jobs on chatgpt.com. Not used for tracking, ads, or scraping unrelated data.
downloads
Download product/design images, redesigned outputs, and stripped-background PNGs only when you click a Download action. Not used for automatic background downloads or unrelated files.
notifications
Optional job or completion feedback for long-running redesign tasks. Not used for marketing.
6. Host Access Explained
The extension only contacts hosts required for its redesign purpose:
Host / scope
Why It's Needed
<all_urls> (content script)
After an explicit user action (right-click, dashboard image import, or supported product-page handoff), resolve and capture the selected design image on ordinary merch/design websites (including layered or lazy-loaded layouts). Also used to add explicit image controls on supported pages such as Amazon and TeePublic. Not used to track browsing history, scrape forms, or collect unrelated page content.
https://chatgpt.com/*
ChatGPT / Custom GPT redesign mode when you enable GPT Mode and start a redesign job. The extension may attach the selected image, submit the redesign prompt, and monitor completion in your ChatGPT session.
Google Gemini when the Gemini source/runtime is active.
https://api.x.ai/*
xAI Grok when the Grok runtime is active.
https://api.bfl.ai/* and https://*.bfl.ai/*
BFL/FLUX when the FLUX runtime is active.
https://securedgateway.link/*
Payment, activation, and account management pages (purchase credits, manage account).
7. Third-Party Services
