2. Description of services

The Services provide a user the ability to transform a file (a "User File") or multiple files ("User Files") from their original file format to a user-selected file format. The Services operate by storing the uploaded User File(s) on a Zamzar server, converting it/them into a new file format ("Converted File(s)"). The recipient can then access and download the Converted File(s) by making a request to the Zamzar API to download it, or by choosing to download it via their "user dashboard".

Zamzar provides four levels of service; "Test", "Startup", "Growth" and "Scale". See https://developers.zamzar.com/pricing for more information about each level of service. You acknowledge and agree that Zamzar may establish general practices and policies concerning use of the Services, including, without limitation, the maximum number of files that a user may upload through the Services, the maximum size of the files that a user may convert through the Services, the maximum number of hours or days that a file will be stored by the Services, and the maximum number of times a user may access the Services in a given period of time. Zamzar reserves the right to change or discontinue any of the Services at any time.

Subject to all the terms and conditions of this Agreement, Zamzar shall supply the Services to you and grant you a personal, non-transferable, terminable licence to use the Services from the Effective Date for the Subscription Period. You may request and Zamzar may agree to upgrade the Services provided to you and the Subscription Fee payable will be amended accordingly for the next monthly payment.

3. Making a Contract with You

If we accept payment you will receive a confirmation on the signup page (at https://developers.zamzar.com/signup) acknowledging that we have received your payment and accepting your offer to subscribe for the Services.

4. Responsibility for Data
