Privacy Policy & Terms of Service

Last Updated: August 11, 2026

Welcome to Telegram Video Downloader by ExtStack ("we," "our," or "us"). We provide a browser extension designed to help users download videos from Telegram. By installing and using our extension, you agree to the terms outlined in this Privacy Policy and Terms of Service.

1. Data Processing, Storage, and Privacy

Your privacy and account security are our highest priorities. We have built our extension with a "local-first" architecture to ensure maximum safety.

• Local Processing Only: All video downloading happens entirely locally on your device within your web browser.
• No Passwords Collected: We never ask for, collect, store, or transmit your Telegram login credentials (passwords). Our tool works seamlessly alongside your existing logged-in session on web.telegram.org.
• No External Servers: We do not send any of your data to external servers or third-party databases. Videos are directly downloaded to your device.
• No Tracking: We do not track your browsing history or your activities across other websites.

2. Required Permissions Explained

To function correctly, our Chrome extension requires specific browser permissions. We only request permissions that are absolutely necessary for the core functionality:

• *://web.telegram.org/*: Required to access videos displayed on Telegram web interface and add download functionality.
• storage: Used to securely save your local extension settings and preferences.
• downloads: Required to save downloaded videos to your device.
• activeTab: Allows the extension to access content in the current tab when you click the download button.

3. Subscriptions and Payments (ExtensionPay)

Our premium features are unlocked via paid subscriptions. We use ExtensionPay (ExtPay.js), a secure, third-party payment processing service designed specifically for browser extensions, which relies on Stripe.

• We do not collect, process, or store your credit card information or billing details.
• ExtensionPay may collect basic information (such as your email address) necessary to process your payment and manage your subscription status.
• You can manage, pause, or cancel your subscription at any time by logging into your ExtensionPay account or by clicking the subscription management link within the extension.

4. Refund Policy (No Refunds)

Due to the nature of digital goods and downloadable software, all sales are final and non-refundable.

• Once a subscription or one-time purchase is completed and the premium features are unlocked, we cannot issue a refund.
• The basic version of our extension is free. We encourage you to test it to ensure it meets your needs before upgrading to a paid plan.
• If you experience technical difficulties, please contact our support team, and we will do our best to assist you in resolving the issue.
• You are responsible for managing your subscription. If you wish to stop being billed, you must cancel your subscription before the next billing cycle.

By using our tool, you agree to use it responsibly and in accordance with Telegram's Terms of Service.

• You are solely responsible for how you use the downloaded content.
• Please respect copyright and intellectual property rights when downloading content.
• We are not responsible for any issues that may arise from using our extension.
