How do I know ODK Cloud will work for me?

The best way is to try it. We're so confident you'll love using ODK Cloud that we have a 14-day, money-back guarantee.

You also don't have to take our word for it. You can learn what users think about ODK Cloud in these user reviews.

How many project spaces do I need?

A single project space has unlimited forms and unlimited data collectors and lets you choose which forms can be used by which data collector.

Multiple project spaces help separate data collection efforts so that a project manager of one project space cannot see or manage the forms in another project space.

Why is the Professional subscription so popular?

Most choose the Professional subscription because of the fast support response time and the expert guidance on form building, custom reporting, API integrations, and more.

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.

I thought ODK was free?

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

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

Do you offer consulting or implementation services?

Yes, whether you use ODK Cloud or self-host, we can help with form building, server management, feature development, user training, and more. Contact us.

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.

ODK Cloud data is backed up continuously and can be restored to a specific moment in time. Backups are kept for 30 days.

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