Follow the changes to the terms of service

Services have terms that can change over time. Open Terms Archive enables users rights advocates, regulatory bodies and any interested citizen to follow the changes to these terms.

Be informed by email of the changes on the documents of your choice.

How ?

How does OTA work?

Every online service provider has terms of use defined in a set of contractual documents that govern the terms of interaction with its users, such as content moderation policies, publisher liability, and jurisdiction in the event of a dispute.

The platform undertakes to aggregate, in a centralized manner, as many contractual documents in as many languages as possible.

In order to track their changes, documents are periodically obtained via a URL and a snapshot is recorded every time a change is made. The meaningful part of the document (without the noise: ads, navigation menu, login fields...) is extracted to be recorded separately.

What we believe in

Large digital companies today occupy a central position which, through the ToS, allows them to transform their practices and values ​​into de facto which are at the heart of many aspects of our existence and our economies.

However, they communicate in an insufficiently clear, readable and continuous manner on these ToS, whereas rigorously understanding the ToS and how they have evolved over time has become essential to appreciate the practices and loyalty of these digital players.

This understanding is also necessary to:

  • each user so that he can identify precisely what he has agreed upon, the data he has shared, the rights he has yielded to the services and the rights he has retained;
  • the authorities in order to verify the compatibility of these contractual frameworks with national and supranational law, in particular when the latter evolve;
  • regulators so that they can assess the efforts of the platforms, but also to make sure that they say what they do and that they do what they say. It creates transparency in the practices of digital players, in line with the first recommendations discussed within the framework of the DSA and the DMA.
