Intellectual Property

The intellectual property in the materials in Vellum and on our website are owned by or licensed to Diomater. You may download Vellum, to view, use, and display the application on your mobile device for your personal use only.

This constitutes the grant of a license, not a transfer of title. This license shall automatically terminate if you violate any of these restrictions or these Terms of Service, and may be terminated by Diomater at any time.

User-Generated Content

You retain your intellectual property ownership rights over content you submit to us for publication within Vellum and/or on its corresponding website. We will never claim ownership of your content, but we do require a license from you in order to use it.

When you use Vellum or its associated services to post, upload, share, or otherwise transmit content covered by intellectual property rights, you grant to us a non-exclusive, royalty-free, transferable, sub-licensable, worldwide license to use, distribute, modify, run, copy, publicly display, translate, or otherwise create derivative works of your content in a manner that is consistent with your privacy preferences and our Privacy Policy.

The license you grant us can be terminated at any time by deleting your content. However, to the extent that we (or our partners) have used your content in connection with commercial or sponsored content, the license will continue until the relevant commercial or post has been discontinued by us.

You give us permission to use your username and other identifying information associated with your account in a manner that is consistent with your privacy preferences, and our Privacy Policy.

Automatic Updates

You give us permission to download and install updates to Vellum on your device in accordance with your privacy preferences. This permission can be revoked at any time by deleting Vellum from your device.


Vellum and the materials in Vellum and on our website are provided on an 'as is' basis. To the extent permitted by law, Diomater makes no warranties, expressed or implied, and hereby disclaims and negates all other warranties including, without limitation, implied warranties or conditions of merchantability, fitness for a particular purpose, or non-infringement of intellectual property, or other violation of rights.

In no event shall Diomater or its suppliers be liable for any consequential loss suffered or incurred by you or any third party arising from the use or inability to use Vellum, our website, or any other services provided by Diomater or the materials in Vellum, even if Diomater or an authorized representative has been notified, orally or in writing, of the possibility of such damage.

You should be aware that there are certain things that Diomater will not take responsibility for. Certain functions of the app will require the app to have an active internet connection. The connection can be Wi-Fi or provided by your mobile network provider, but Diomater cannot take responsibility for the app not working at full functionality if you don’t have access to Wi-Fi, and you don’t have any of your data allowance left.

If you’re using the app outside of an area with Wi-Fi, you should remember that your terms of the agreement with your mobile network provider will still apply. As a result, you may be charged by your mobile provider for the cost of data for the duration of the connection while accessing the app, or other third party charges. In using the app, you’re accepting responsibility for any such charges, including roaming data charges if you use the app outside of your home territory (i.e. region or country) without turning off data roaming. If you are not the bill payer for the device on which you’re using the app, please be aware that we assume that you have received permission from the bill payer for using the app.

Along the same lines, Diomater cannot take responsibility for the way you use the app i.e. You need to make sure that your device stays charged – if it runs out of battery and you can’t turn it on to avail the Service, Diomater cannot accept responsibility

In the context of this agreement, “consequential loss” includes any consequential loss, indirect loss, real or anticipated loss of profit, loss of benefit, loss of revenue, loss of business, loss of goodwill, loss of opportunity, loss of savings, loss of reputation, loss of use and/or loss or corruption of data, whether under statute, contract, equity, tort (including negligence), indemnity, or otherwise.

Because some jurisdictions do not allow limitations on implied warranties, or limitations of liability for consequential or incidental damages, these limitations may not apply to you.

Accuracy of Materials

The materials appearing in Vellum or on our website are not comprehensive and are for general information purposes only. To the extent permitted by law, Diomater does not warrant or make any representations concerning the accuracy, likely results, or reliability of the use of the materials in Vellum or on our website, or otherwise relating to such materials or on any resources linked to Vellum and our website.


Diomater has not reviewed all of the sites linked to Vellum or on its corresponding website and is not responsible for the contents of any such linked site.

Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms of Service, and upon your acceptance of these Terms of Service, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms of Service against you as a third-party beneficiary of these Terms of Service.

You hereby represent and warrant that (1) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (2) you are not listed on any U.S. Government list of prohibited or restricted parties.

Right to Terminate

We may suspend or terminate your
