How we secure your data


Our clients use Ona to collect, analyze, and disseminate mission critical data. We have worked on both the data collection side as well as the platform side and understand the importance of knowing your data is stored safely and securely. Here we’ll talk about the specific technologies we use to secure our users’ data.


Specifically relating to data security, the highlights of the standards we incorporate are:

  • Encrypted server-client connections using TLS/HTTPS
  • A+ certified server-client TLS configuration
  • Encrypted at-rest database and encrypted database backups using AES-256
  • ISO 27001 security management certification via AWS data centers


To make sure that your data stays secure during events that we cannot anticipate, such as a hardware failure with our hosting provider, we create nightly replicas of our entire database. This way, should the worst happen, we will be able to recover quickly and get back up and running with minimal data loss.


The privacy protections afforded your data are described in our Privacy Policy. One of the most important parts:

We take the privacy, confidentiality, and security of any data you submit or upload to Ona very seriously, because it is your data. You retain ownership of the data. We will never share or access your data, unless granted permission by you, in order to provide you with technical assistance.

Please read Ona’s full Privacy Policy along with our Terms of Service for more details.

Steps you can take

Security is only effective when users follow best practices; e.g. do not share passwords, do not write down passwords, and do not use public computers (but if unavoidable always log out of the site when finished using Ona on public computers). If your project requires a higher level of privacy, Ona also allows you to encrypt your forms with decryption only possible using ODK Briefcase and encryption keys.

Thank you and happy holidays 2016!



With 2016 coming to an end, the whole Ona team wanted to send a “Thank You” to all of the customers, users, friends, and family of Ona. To show how happy we are to have your support, we created the Thank you / happy holidays survey.

What’s new?

Fine-tune data access permissions on projects

The fine-tuned data access permissions for Can Submit and Can Edit roles we mentioned in the October newsletter are live. Previously, Can Submit and Can Edit users had access to all project data. Now, project admins can choose to restrict data access for those users — either by granting access to only the data each individual user has submitted, or completely hiding data from Can Submit users. Hiding all data is something you may do for enumerators. These permission options are set at the form level. You can find them in Form Settings ⇒ Permission Restrictions, or read the permission restrictions help article. Here’s what the new options look like:

High-resolution satellite basemap new in Ona maps



We are excited to announce the addition of a high-resolution satellite basemap from DigitalGlobe. This will provide over 150 million square kilometers of the earth’s surface in astonishing clarity. DigitalGlobe offers the highest resolution (it’s the only company that offers 30 cm resolution imagery) and most up-to-date satellite imagery available on the market. It’s a big investment, but one we are happy to make if it helps our users see the world more clearly.
