Why use ODK Cloud?

ODK Cloud is the official managed hosting service from the creators of ODK. It's the same ODK that millions use, but made even easier so you can focus on collecting the data you need.

To help accelerate your work, ODK Cloud comes with priority support and professional services from the ODK team.

How do I know ODK Cloud will work for me?

The best way is to try it! If within 14 days of payment you are unhappy for any reason, let us know, and we will issue a refund.

You can also request a personalized demo with the ODK experts to make sure ODK Cloud will work well for you.

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 and submissions 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 if I can't afford ODK Cloud?

ODK is open-source software, so you can self-host it and rely on volunteers on the forum for help. Start with the docs.

What if I can't use cloud services?

If you need to self-host ODK, we can help with the initial install and provide ongoing support. Contact us for pricing.

What payment methods do you accept?

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

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 for your subscription. Both data centers are GDPR compliant and ISO27K, CSA STAR, and SOC 2 certified.

Do you offer consulting or implementation services?

Yes, we can help with form building, feature development, self hosting, and so much more. Contact us to get started.
