Thank you for using Subseven. Protecting your privacy is important to us.
This Privacy Policy explains what information Subseven collects about you, why we collect it, how we use and share it, and the choices you have regarding your information.
This Policy applies to all users of the Subseven mobile application, including iOS and any future Android version, and any related services provided by us.
By using the App, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with our policies and practices, please do not use Subseven.
In summary, Subseven collects personal information (such as your name and email) and health-related information (such as events you log and health data you authorize through connected services) in order to provide our service. We use this data to give you insights about your diabetes management and to improve our product. We do not sell your personal information or share it with third parties for their own marketing.
We take measures to secure your data and to use it responsibly, including following health data privacy best practices and applicable platform guidelines.
We collect several types of information from and about users of the Subseven App.
When you create an account, we ask for your name and email address. We use your email to create your login credentials, for account verification, and to communicate with you, such as sending receipts or important announcements.
Optionally, we may also collect other profile information if you choose to provide it, for example if the App allows adding a profile picture or basic demographic information in the future.
The core of Subseven’s service is to log events and analyze blood glucose patterns and related factors. To that end, we collect the following categories of data.
Event Log Data
Any events you manually log in the App, including meals, insulin doses, workouts, exercise details, stress levels, sleep quality or disturbances, menstrual cycle information (if you log a period), travel or vacation indicators, and other notes that might affect blood glucose. These inputs are structured through the App’s interface and stored so that the App can correlate them with other health data and generate insights.
Blood Glucose and Diabetes Data from Connected Sources
Subseven may obtain blood glucose data and related diabetes signals through integrations that you explicitly authorize. These sources may include Apple HealthKit, Dexcom via the Dexcom Developer program, and other approved sources as we add support. We only access these data sources with your permission, and you may revoke access at any time through the relevant platform or integration settings. Blood glucose and diabetes-related data is treated as sensitive health information and protected accordingly.
Apple HealthKit Data (iOS)
On iOS, Subseven integrates with Apple’s HealthKit to retrieve blood glucose readings and other authorized health data from the Apple Health app. We access HealthKit data only with your explicit permission and only for the purpose of providing health-related services through the App. We do not use HealthKit data for advertising, marketing, or unrelated analytics.
Dexcom API Data
If you choose to connect Dexcom, we may retrieve blood glucose readings and related information made available through Dexcom’s APIs under their Developer program. We use this data to power charts, analytics, summaries, and pattern detection inside Subseven. Dexcom data is not sold and is not shared with third parties for their marketing purposes.
Whoop API Data
If you choose to connect Whoop, we may retrieve wellness and activity signals such as sleep, recovery, strain, and related metrics through the Whoop Developer program. We use this data to enrich analysis and help explain patterns that may influence blood glucose or overall stability. Whoop data is not sold and is not shared with third parties for their marketing purposes.
Rook Integrations (tryrook.io)
Subseven uses Rook (tryrook.io) as an integration partner to connect to supported wearable, fitness, and health data sources. If you choose to connect a source through Rook, we may retrieve activity, workout, sleep, heart rate, and other metrics supported by the underlying provider and authorized by you. Rook acts as a service provider processing data under our instructions so the integration can function. We do not allow Rook to use your data for its own marketing purposes. We encourage you to review Rook’s privacy disclosures as well.
When you use the App, we may collect certain information automatically, such as device model, operating system version, and device identifiers to ensure compatibility and optimize performance. We may also collect log data such as login timestamps, feature usage, errors, and crashes. This information is typically anonymized or aggregated.
For Android (when available), we may collect similar device and usage information necessary to operate and improve the App.
All subscription purchases are handled through the applicable app marketplace in-app purchase system. We do not collect or store your credit card or billing information. We receive confirmation of purchase status, subscription type, and anonymized transaction identifiers. Refunds are handled by the marketplace provider under their policies.
If you contact us via email or in-app support, we collect the information you provide in that correspondence. This information is used solely to assist you and resolve your inquiry. We do not collect Social Security numbers, government IDs, contact lists, precise GPS location, photos, or unrelated device files unless you intentionally provide them for support purposes.
We use the information we collect to provide and improve the App, personalize your experience, communicate with you about your account, generate anonymized and aggregated analytics, and comply with laws and enforce our policies.
We do not sell or rent your personal information. We do not share personal data for advertising or marketing purposes. Trusted service providers may process limited data under confidentiality agreements and only under our instructions. We may share anonymized or de-identified insights publicly or for research purposes. We may disclose information if required by law.
We implement encryption, access controls, secure servers, monitoring, and secure development practices. No system is completely secure, but we continuously improve our safeguards.
We retain personal data while your account is active and as needed for legitimate purposes. De-identified research data may be retained indefinitely. Deleting the App alone does not delete your account or stored data.
You may request access, correction, deletion, restriction, or export of your data. To exercise these rights, contact chris@subseven.ai.
