Article 4: Data integrity and accuracy

Because we use 100% machine technology, we ensure that the bid data is not edited by experts of the Information Center However, despite our best efforts, we cannot guarantee 100% that the data will not be corrupted during the collection process. Especially the error is caused by the National Procurement Network System itself (which cannot access all public data and use all functions using modern browsers such as Chrome, FireFox, Edge). Data can also be hacked and manipulated from the outside. however we will try to keep these issues to a minimum as committed.

Due to technology limitations and the requirement not to automatically scan data into the National Procurement Network, there will be cases where the data is posted to the National Procurement Network but is modified or deleted without the system being able to do so. The software system of could not be updated in a timely manner.

Since the data on the National Procurement Network is unlinked, DauThau.INFO converts them into linked data based on the analytic information from the database. Due to technology limitations and inaccuracies from the original data, this data association may not be 100% accurate. The user is solely responsible for checking and comparing the accuracy of the data and is solely responsible for any damages (if any) arising from the use of this data (See also " Terms and terms of service" for more details)
