What is a project space?

A single project space has unlimited forms and unlimited users and lets you assign specific forms to specific data collectors.

Multiple project spaces are best for organizations who need to separate data management by team, site, or country.

What are the benefits of the Professional subscription?

In addition to more submissions, storage, and support, the Professional subscription has features that enable longitudinal data collection, case management, field inspections, and more.

Also included is REST API access for building custom integrations to automate your workflows.

What are your data security practices?

All data is encrypted in transit and at rest in ODK Cloud. End-to-end encryption with self-managed keys is also available.

You can choose between US or EU data centers. Both data centers are GDPR compliant and ISO27K and SOC 2 certified.

How do I know ODK Cloud will work for me?

If you are unsure, request a demo with a data collection expert to get a walkthrough of ODK features that meet your needs.

I thought ODK was free?

ODK is open-source software. If you're technical, you can self-host and self-support it for free. Start with the docs.

ODK Cloud is the same ODK software, but fully hosted, managed, and supported by the creators of ODK.

What payment methods do you accept?

We accept major credit and debit cards. Bank transfers are only accepted on yearly subscriptions. All prices are in USD.

What is your refund policy?

If you're unhappy with ODK Cloud for any reason, email us within 14 days of payment and we'll refund you in full.
