The RIPPLE Study

 We’re looking for people who:

• Live with any form of diabetes
• Live in the United States
• Are 18 years or older
• Are willing to share their diabetes device and Oura Ring data

No, you can have any form of diabetes. This includes: 

• Type 1 diabetes
• Type 2 diabetes
• LADA (Latent Autoimmune Diabetes in Adults)
• Monogenic diabetes (such as Maturity-Onset Diabetes of the Young)
• Gestational diabetes
• Secondary forms of diabetes (for example, diabetes related to pancreatic conditions, cystic fibrosis, medications, or medical treatments)
• Pre-diabetes 

Even though type 1 diabetes is Tidepool’s main focus, we want this collaboration to result in datasets that are diverse, inclusive, and representative of the diabetes community.

For this study, you must be using a Tidepool-supported device(s). You can review the full list of devices supported by Tidepool] to see if yours is compatible.

While the RIPPLE Study is only available to participants of the Tidepool Big Data Donation Project, you can opt in to the TBDDP at any time!
Read our support articlet to see how you can sign up.

There are a few steps to get you all set up for the study: 

• Take a brief eligibility screener
• Sign an informed consent form, which details what data will be captured, how it will be used, and your benefits as a participant 
• Complete a detailed health survey
• Order your Oura Ring Sizing Kit and Oura Ring 
• Link your Oura account to Tidepool 
• Plan to wear your new Oura ring regularly 
• Share your diabetes device and Oura data for up to a year 

After setup, participation primarily involves going about your daily life while wearing your devices and sharing data. This is an observational study and does not involve any treatments or changes to your care.

‍

The Oura Membership offer is for a year. At the end of the year, you can choose to continue your Membership for a fee or cancel it. If you choose to continue wearing your Oura Ring, you can share your data with Tidepool for as long as you wish. 

Your Oura Ring will also come with a single charging cable and instructions for your Oura Ring and Oura account setup. 

*Please note that you will need to have your own USB-A power adapter. Your Oura Ring and charging cable will not come with one.

No. The Oura Ring Gen3 is yours to keep. 

Your complimentary Oura Membership will be active for 1 year. If you’d like to continue your Oura Membership after that point, that cost will not be covered by the study. 

Refurbished Oura Ring devices are in excellent working condition and may feature minor cosmetic imperfections. Each unit is thoroughly cleaned, factory reset, and repackaged with all essential components.

Your Oura Ring and 1 year Oura Membership are provided at no cost. There is a one-time $20 shipping charge for the sizing kit and Oura Ring orders.  

Once your order is placed, all Oura Ring orders are final and cannot be changed. 

‍

For this purpose, we encourage you to take time with the sizing kit to feel confident about your choice. Try wearing it throughout the day during your usual activities to see what’s most comfortable. A full 24 hours will give you the clearest picture of what feels best.

Please get in touch with us.

At this point, you will only be able to participate in the RIPPLE Study with Oura Ring provided through this study. 

If you’re interested in being notified when users can connect their existing Oura accounts and Oura Ring data to Tidepool, submit your email address below.

Please get in touch with us.

You can stop participating in the RIPPLE Study and the TBDDP at any point. Participation is completely voluntary. Withdrawing from the RIPPLE Study does not affect your access to Tidepool services or your Oura Ring.

‍
After you’ve logged into your account, click “Profile” in the navigation bar.
Next, select “Stop Sharing Data” under the Tidepool Big Data Donation Project section.
Confirm by clicking “Yes, stop sharing.”

‍
Note: If you choose to opt out of the TBDDP, your data will no longer be included in future datasets. However, data previously shared cannot be removed or deleted.

You will receive a notification in your in-app Membership Hub along with an email letting you know that your complimentary membership is about to expire.

‍

To continue your membership, you will need to pay the membership fee. If you choose not to continue your membership, you will no longer be able to access Oura's membership features. You will not automatically get charged to continue your membership.

After removing all identifying information, the data we provide researchers is in either .csv, .json, or .xlsx format that looks like this.

‍
We store data in Tidepool’s secure, HIPAA-compliant servers that are hosted by Amazon Web Services (AWS). Within AWS, we use MongoDB, a popular, modern database.

‍
Here is an example data file (6MB compressed) for our demo user, “Jill Jellyfish" before removing identifiers. It follows the Tidepool data model which is how we internally represent data.

Tidepool uses industry best practices, including end-to-end encryption, to secure your data. You can read detailed information all about in our security infrastructure document.

‍
For the Big Data Donation Project, Tidepool strips all identifying information from data sets for the Tidepool Big Data Donation Project. In addition, Tidepool replaces your Tidepool user identifier (that looks something like 0a1b2c3d) with a “hash” value that is generated using a cryptographically secure one-way hash function. These identifiers cannot be decrypted into their original form, even by Tidepool, but they allow researchers to correlate datasets from the same user over time.

‍
Like all de-identified health data, there is a small risk that your data could be linked back to you if it were combined with other information outside our control. We take technical and legal steps to minimize this risk, including requiring all data partners to sign agreements that forbid anyone from trying to identify you. If a data breach were to occur, we would follow HIPAA guidelines to notify you of the details.

If you opt in and then later change your preference to opt out, your data will not be included in any future datasets.
However, data that was previously shared with researchers cannot be recalled or deleted, as it has already had identifiers removed and incorporated into existing datasets. This is explained in the informed consent form before you enroll.

Tidepool may have access to certain reproductive health-related data depending on what you choose to track and share.

‍

If you use the Oura App to log reproductive health information—such as menstrual cycle insights (for example, cycle timing and length or pregnancy-related information)—and choose to share that data with Tidepool, it may be included in the study dataset.

‍

As part of the study, you will also be asked to complete a health survey. You can choose whether or not to share any reproductive health–related information in your responses.

‍

In addition, Oura Ring collects physiological data such as temperature trend deviation, which contributes to metrics like your Readiness Score. While this data is not labeled as reproductive health data, it can sometimes be used to model or infer physiological states, including aspects of reproductive health such as cycle timing.

‍

You can learn more about how Oura uses temperature trend deviation to track your cycle, and how to manage or opt out of sharing certain data with Tidepool, in Oura's support documentation.

Participation in the RIPPLE Study does not require you to share any data you do not consent to share.

Yes, you can update your preferences to stop sharing your data with Tidepool at any time. Read our support article for more information.
