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 site, program, or country.

Only active project spaces (e.g., received submissions, exported data) count against your monthly quota.

What if I need more project spaces or submissions?

You can add more project spaces or monthly submissions with a Basic add-on for $199/month (if paid yearly) or $249/month (if paid monthly). Each Basic add-on adds 1 project space and 10K monthly submissions.

Monthly submissions and subscription features are shared across all the project spaces of a subscription.

What are the benefits of the Professional subscription?

In addition to more submissions and faster support, the Professional subscription adds Entities, a feature that enables longitudinal data collection, form linking, case management, and other dynamic workflows.

Also included is API access for building custom integrations that automate your data collection, management, and usage.

What are the benefits of the Enterprise subscription?

The Enterprise subscription adds single sign-on, custom domains, uptime SLA, a success manager, and more.

Enterprise subscription pricing starts at $2,495/month.

How do I know ODK Cloud will work for me?

You can learn what customers think in these user reviews. You can also 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.

Do offer free trials?

We offer a 14-day money-back guarantee. If you sign up and decide within 14 days of payment that ODK isn't a great fit, email us for a full and instant refund.

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.

All data is continuously backed up 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.

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.
