Knowsi and your data

Knowsi is a platform to manage participant consents in the era of GDPR, so we take this stuff pretty seriously.

  1. Both Users of Knowsi (i.e. those paying to use the platform or who are on test accounts) and Participants in those users' research (someone who signs or chooses not to sign a consent form) have distinct controls over their own data. Deletion or request of that data is automated.
  2. By design, we're trying hard not to store any more data than is actually required. We're also open to feedback.
  3. When you submit a GDPR request, we NULL out any identifiable information. That means that if you as a subject hit the "Forget Me" switch, the person who interviewed you will no longer have access to anything identifable as you. However, the relationships within the database with those nulled values.
  4. When you sign a document, the data within that document (what you saw) and the individual consents are saved as unique and immutable files. This means that if someone updates or changes a document, the version YOU signed will not change.
  5. We require that participants opt-in to consents, instead of having things automatic. It's a small detail, but we've found in our testing that research participants don't understand what they've agreed to when following opt-out consent patterns.

Third Party Services

Knowsi uses a variety of third party services to host infrastructure and generally make a small product like this possible.

  • For Payment: Stripe

    We use Stripe to manage all payments. Subscriptions and payments are handled at the organizational level, so a distinct billing address can be used.
  • For DNS Management and Cache: Cloudflare

    We use Cloudflare to manage our DNS routing, caching, and SSL certification.
  • For Analytics: Matomo

    We respect your right NOT to be tracked, and so if you have tracking disabled in your browser, Matomo won't track you. Not sure how that works? Check out UBlock Origin, which is the content filter we use.
  • For Bug Tracking: Sentry.io

    Sentry is running on both the frontend and the backend servers to notify the Stupid Systems LLC team of bugs or errors that you might encounter. We have the data scrubber option enabled, and don't store any personally identifiable information through the service.
  • For Hosting: Heroku

    Knowsi is hosted across multiple Heroku instances, with the database and backups hosted through Heroku as well. Heroku uses Amazon AWS to host its services, and is compliant to a level we value.
  • For Transactional Email: Postmark

    Postmark does store emails sent through its server and have a distinct GDPR policy.
  • For Marketing Email: We self host.

    That system is hosted on Heroku (and AWS) and sends data through Amazon Simple Email Service. The mailing lists are encrypted and to get on the system itself, you need to fulfil a GDPR consent at the point of signing.
  • For Image Storage: Cloudinary

    . We use Cloudinary for basic image storage of organization logos only. Participant and user data isn't stored there.
  • For File Management: Google Drive

    We provide the ability for researchers to sync their google drive account with a Knowsi project in order to keep track of any media that the participant consented to have collected.
    This data and the google drive account are managed by Google's own privacy policy, and users authenticate using their existing google account. We endevour to automate or make complete as much of the GDPR deletion request as is possible as a 3rd party applicaiton using the Google Drive API. This media or data doesn't touch Knowsi's servers, and is managed entirely by the frontend of the application. We only store reference IDs to the top-level folder where this data is meant to be stored.
    We use the Google Picker API to help you select a folder, and the google drive API to upload files via the frontend. We will never look at anything else outside of the folder you select, which is done via the picker API.
