We never collect personally identifiable information. We never disclose, share, or sell any of your data to third parties.
Through using our app, you may send data to servers managed by individuals or organizations you're working with. We encourage you to ask these individuals or organizations about their data privacy policies, as they may differ from ours. We provide the same standard of privacy protection to all our users no matter where you are in the world.

The App is not intended for children under 16 years of age, and we do not knowingly collect personal information from children under 16.

4. Information you send through the App
When you use the App to transmit data, you connect to the server of a Deploying Organization that is overseeing the documentation or data-collection process to send photos, videos, audio recordings, and other files, metadata, and text data (collectively, “User Contributions”).
The Deploying Organization manages and is responsible for the server on which the data you submitted, including User Contributions, is stored. It is the Deploying Organization, and not the Company, who owns that data and is responsible for its handling and use. The Company does not have access to or control over the data collected by Deploying Organizations.
Your User Contributions are transmitted at your own risk. The privacy and security of your User Contributions are very important to us, and we work hard to protect them; however, no security measures are perfect or impenetrable, and the Company shall not be held responsible for any damage, loss, or unauthorized access by third parties.
In the event that a Deploying Organization contracts with the Company to install and manage the server on which user data is stored, the Company will have access to the data as a partner to the Deploying Organization. The Company will be able to view, control, and manage your data, but will not disclose it to any third party other than the contracting Deploying Organization.
Without limiting the foregoing, Company employees do not access private spaces unless required to for security reasons, to assist the Deploying Organization with a support matter, or to maintain the integrity of the service.

- Your mobile device manufacturer.
- Your mobile service provider.
- The Google Play store, if you install the App through it.
These third parties may use tracking technologies to collect information about you when you use this app. The information they collect may be associated with your personal information, or they may collect information, including personal information, about your online activities over time and across different websites, apps, and other online services websites. They may use this information to provide you with interest-based (behavioral) adverting or other targeted content.
We do not control these third parties’ tracking technologies or how they may be used. If you have any questions about an advertisement or other targeted content, you should contact the responsible provider directly.

9. Data Security
We have implemented measures designed to secure your personal information from accidental loss and from unauthorized access, use, alteration, and disclosure. All information you provide to us is encrypted inside the app and securely transferred to our servers behind firewalls.
