VideoToMP4 privacy policy

Last updated: 2026-10-06

VideoToMP4 is a free Chrome extension made by PostOnce. It saves Facebook, Instagram, TikTok and Pinterest posts you choose to your computer. This policy explains what the extension can access, what it stores, and what it sends.

What the extension accesses

• Facebook, Instagram, TikTok and Pinterest pages you open. The extension runs only on facebook.com, instagram.com, tiktok.com and pinterest.com. It places a Download button beside posts and, when you click it, reads that post's media details from the page and from the platform's own servers, using the session already open in your browser.
• Media files. It downloads the video, audio or image files of the post you chose directly from the platform's servers and combines them inside your browser.
• Your downloads. It uses Chrome's downloads feature to save the file and to show it in your folder.

The extension does not read other websites, your browsing history, your Facebook, Instagram, TikTok and Pinterest password, messages, or any post you didn't click Download on.

What stays on your computer

• Downloaded files are saved by Chrome to your downloads folder. They are never uploaded to PostOnce or anyone else.
• The extension keeps a small amount of local data in Chrome's extension storage: your settings (for example, whether you chose Not now on the review request) and the status of your latest download so it can recover if a tab closes. You can clear this in Help & privacy → Reset preferences, or by removing the extension.

What the extension sends to PostOnce

Nothing. The extension has no analytics or usage tracking. It doesn't send PostOnce, or anyone else, information about the posts you view or download.

Leaving a review

After a download, the extension may ask you to review it. If you click Leave a review, the extension's Chrome Web Store page opens in a new tab. Nothing about your download, file or Facebook, Instagram, TikTok and Pinterest account is passed along. The extension stores only whether you clicked it or chose Not now, on your computer, so it doesn't keep asking.

What we don't do

• We don't sell or share data.
• We don't use data for advertising, creditworthiness or lending.
• We don't load remote code. All extension code is included in the package reviewed by the Chrome Web Store.
• We don't collect your Facebook, Instagram, TikTok and Pinterest login. If the platform asks you to sign in or confirm you're human, you do that on the platform yourself.

Your responsibility

Only download posts you own or have permission to reuse. VideoToMP4 is an independent tool and is not affiliated with, endorsed or sponsored by Meta Platforms, Inc., TikTok Pte. Ltd., ByteDance Ltd. or Pinterest, Inc.
