AutoSync Privacy Policy

Published by AutoFy. Effective date: November 11, 2026.

AutoSync reads the vehicle details and photos on a dealership page only when you click its button, uses an AI service to write your listing text, and fills in the Facebook Marketplace form for you. Using AutoSync requires a subscription, which is verified with a license key. We do not sell your data, show ads, or track your browsing.

1. Who we are

AutoSync (the “extension”) is a Chrome extension published by AutoFy (“we”, “us”). If you have questions about this policy, write to [email protected].

2. What the extension does

AutoSync helps car dealerships and independent sellers post a vehicle from their own website to Facebook Marketplace. When you click the “Create Post” button on a vehicle, the extension reads that vehicle’s details and photos, opens the Facebook Marketplace vehicle form, and lets you generate a listing title and description with AI. You review the result and publish the listing yourself. The extension never publishes anything on its own.

3. Information the extension handles

Information	When	Where it goes
Vehicle details from the dealership page: title, price, mileage, stock number, VIN, specifications, colors, equipment, and up to 15 of the vehicle’s photos	Only after you click the AutoSync button on a vehicle	Kept temporarily in the extension’s local storage so the Facebook tab can use it. The text details (not the photos) are also sent for AI generation, as described in section 5.
The instructions (prompt) you write for the AI	When you save them, and each time you generate text	Saved in the extension’s local storage. Sent with the vehicle details for AI generation.
Your AutoSync license key	When you paste it in the extension, and each time the extension checks your subscription or generates text	Saved in the extension’s local storage. Sent to our server only to verify that your subscription is active.
The result of the last license check (for example “free trial, 5 days left”)	Each time the license is checked	Local storage only
Your interface language choice and a daily usage counter	When you change the language / each time text is generated	Local storage only
The generated title and description, and the values filled into the Marketplace form	When you use the side panel on Facebook	Shown to you in the browser and typed into the Facebook form. We do not keep a copy.

The extension runs on websites you visit so it can show its button on vehicle listings and vehicle pages, but it does not read, store, or send the content of pages until you click the button. Pages that are not vehicle listings are ignored.

4. Subscription and license key

AutoSync is offered as a subscription with a free trial. The subscription is handled outside the extension:

Payment. You subscribe on a checkout page operated by Stripe. Card and payment details are entered on Stripe’s page and processed by Stripe; they never reach the extension or our server.
What we receive. When you subscribe, Stripe sends us your email address, a customer ID and a subscription ID, the subscription status (for example trial, active, canceled) and the end date of the current period. We store these on our server together with the license key we create for you.
License email. We email your license key to the address used at checkout. The email is sent through Brevo, an email delivery service.
License checks. When you activate the extension, open its popup, start a post or generate text, the extension sends your license key to our server, which replies only whether the subscription is valid and until when. Your email address is not sent back to the extension.
Managing your subscription. You can update your payment method or cancel at any time through the Stripe customer portal linked in the extension and in the license email.

The extension itself never asks for your name, email address, phone number or payment details.

5. How AI text generation works

When you click “Generate text & fill”, the extension sends the vehicle’s text details, your prompt and your license key to a server operated by AutoFy (hosted on Supabase). The server checks the license, adds our access key and forwards the vehicle details and your prompt to Google’s Gemini API, which returns the title and description. Vehicle photos are not sent to the AI service.

Our server does not store the content of your requests or the AI’s responses. It keeps only what it needs to run: its configuration (such as access tokens and the list of AI models) and the subscription records described in section 4.
