We use that data to provide Cardiolog features, store it on your device and on our servers as described below, and we do not sell it. We do not share Garmin data with analytics providers or with third-party artificial intelligence (AI) services. We may use Garmin data to develop, train, and improve our own proprietary machine learning models that run on your device and in our cloud environment to improve Cardiolog for our users.
How we collect Garmin data. Cardiolog for iOS lets you link Garmin Connect using OAuth ("Connect Garmin"). You may also choose to use Apple HealthKit; data you authorize from HealthKit is covered elsewhere in this notice. This section applies only to data we receive from Garmin when you connect Garmin.
Categories of Garmin data. Depending on your Garmin device, account settings, and the permissions you grant, we may collect available health and fitness metrics from Garmin, including for example: heart rate, heart rate variability (HRV), sleep, stress, steps, workouts and activities, blood oxygen (SpO₂), blood pressure, and other medical or wellness metrics made available to us through the Garmin Health API.

If you are located in the EU or UK, this section applies to you.
The General Data Protection Regulation (GDPR) and UK GDPR require us to explain the valid legal bases we rely on in order to process your personal information. As such, we may rely on the following legal bases to process your personal information:
Consent. We may process your information if you have given us permission (i.e., consent) to use your personal information for a specific purpose. You can withdraw your consent at any time. Learn more about
withdrawing your consent.
Performance of a Contract. We may process your personal information when we believe it is necessary to fulfill our contractual obligations to you, including providing our Services or at your request prior to entering into a contract with you.
Legitimate Interests. We may process your information when we believe it is reasonably necessary to achieve our legitimate business interests and those interests do not outweigh your interests and fundamental rights and freedoms. For example, we may process your personal information for some of the purposes described in order to:
Send users information about special offers and discounts on our products and services
Develop and display personalized and relevant advertising content for our users
Analyze how our Services are used so we can improve them to engage and retain users
Support our marketing activities
Diagnose problems and/or prevent fraudulent activities

Vital Interests. We may process your information where we believe it is necessary to protect your vital interests or the vital interests of a third party, such as situations involving potential threats to the safety of any person.
In legal terms, we are generally the "data controller" under European data protection laws of the personal information described in this Privacy Notice, since we determine the means and/or purposes of the data processing we perform. This Privacy Notice does not apply to the personal information we process as a "data processor" on behalf of our customers. In those situations, the customer that we provide services to and with whom we have entered into a data processing agreement is the "data controller" responsible for your personal information, and we merely process your information on their behalf in accordance with your instructions. If you want to know more about our customers' privacy practices, you should read their privacy policies and direct any questions you have to them.
If you are located in Canada, this section applies to you.
We may process your information if you have given us specific permission (i.e., express consent) to use your personal information for a specific purpose, or in situations where your permission can be inferred (i.e., implied consent). You can
withdraw your consentat any time.
In some exceptional cases, we may be legally permitted under applicable law to process your information without your consent, including, for example:
If collection is clearly in the interests of an individual and consent cannot be obtained in a timely way
For investigations and fraud detection and prevention
For business transactions provided certain conditions are met
If it is contained in a witness statement and the collection is necessary to assess, process, or settle an insurance claim
For identifying injured, ill, or deceased persons and communicating with next of kin
If we have reasonable grounds to believe an individual has been, is, or may be victim of financial abuse
If it is reasonable to expect collection and use with consent would compromise the availability or the accuracy of the information and the collection is reasonable for purposes related to investigating a breach of an agreement or a contravention of the laws of Canada or a province
If disclosure is required to comply with a subpoena, warrant, court order, or rules of the court relating to the production of records
If it was produced by an individual in the course of their employment, business, or profession and the collection is consistent with the purposes for which the information was produced
If the collection is solely for journalistic, artistic, or literary purposes
If the information is publicly available and is specified by the regulations
