Privacy Policy

Last updated: October 22, 2026

This policy explains what information t4io (https://t4io.com) collects and how it is used. The short version: the files and text you use with our tools never leave your device.

Your files and text

All tools on this website run inside your web browser. Videos, pictures, text, passwords and other content you put into a tool are processed on your own device and are not uploaded to, stored on, or seen by our servers.

The video tools download a free video engine (ffmpeg) from a public content delivery network (jsDelivr) the first time you use them. Only the engine is downloaded; your video is not sent anywhere.

Advertising and cookies

We use Google AdSense to show ads, which keeps the tools free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.

You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info. Learn more about how Google uses information from sites that use its services.

Visitors from the European Economic Area, the United Kingdom and Switzerland are shown a consent message, and personalized ads are only shown if they agree.

Basic visit statistics

Like most websites, our hosting provider may keep standard server logs (such as IP address, browser type and the page visited) for security and to keep the site running. We may use privacy-friendly statistics to count visits to each tool. We do not sell personal information.

Children

Our tools are safe for all ages and we do not knowingly collect personal information from children under 13.

Changes

If this policy changes, we will update the date at the top of this page.
