Description

MP4 (short for MPEG-4 Part 14) files store multimedia - video, audio and subtitles. Websites frequently use them for displaying videos because the MP4 format is universally supported.
However, newer video formats, such as WebM, produce smaller file sizes with almost no quality loss. Therefore, you can free up storage by converting your videos to WebM.

This page informs you of our policies regarding the collection, use and disclosure of personal data when you use our Service and the choices you have associated with that data. We use your data only to provide and improve the Service.

Data Collection

We only collect the minimum amount of necessary data for providing and improving the Service.

By visiting and/or using our Service, your IP address will be logged, together with the user agent, HTTP referrer, and date and time of access.

If you contact us, we collect certain personally identifiable information, such as email and name, so that we can respond to enquiries.

When providing a file for conversion, we do not read or collect the file’s contents for reasons different from converting the file. We collect the number and types of errors when converting, as well as the original file size and name, for statistical purposes.

If you create an MConverter account, we collect your email address and profile picture.

If you choose to support MConverter's development, we may need to collect some information, such as your email address, in order to verify the purchase and unlock your benefits. All financial transactions are handled by Stripe, PayPal, or Google Play. We do not collect your debit/credit card data.

Handling of User Files

We do not make any copies of them. All file processing is done by machine and there is no human interaction with your files. Your files are automatically and irreversibly deleted from our servers at the latest after 72 hours, for conversion with an error. The files of successful conversions are deleted 24 hours after their completion. You can also manually initiate the deletion by clicking the DELETE NOW button.

Sharing of User Data

Your uploaded files will not be given out or sold to anyone. The same applies for the data associated with your MConverter account, if you have one. Any other personally identifiable information will not be given out or sold, either.

We will keep your personal data only for as long as it is necessary to provide you with our Services.

Your Rights

You have the right to be given a copy of information held by us about you. We will provide the requested information to you within 30 calendar days of the receipt of a valid request in writing.
