Privacy policy

Last updated: 2026-06-03

Circadian Group LLC ("we", "us", "Solas") operates this marketing site (solasmoms.com) and the Solas iOS application. This policy describes what we collect, why, who we share it with, and how to delete it. Questions: info@circadiangroupllc.com.

The Solas iOS app

Account and identity

• Email address. Used to create and sign in to your account. You can sign in with an email and password or with Sign in with Apple.
• User and device identifiers. A user ID and a device identifier are used to associate your data with your account and to sync across reinstalls.

This data is linked to your identity.

Health and wearable data

• Apple Health (HealthKit). With your explicit permission, we read sleep, heart-rate, and related metrics. Health data is processed on-device where possible and is encrypted in transit otherwise.
• Oura and WHOOP. Optional connections you authorize via OAuth. Access tokens are stored encrypted, and you can revoke any source from the app's Settings screen.

We never use your health data for advertising, never sell it, and never use it to train AI models.

Pregnancy and postpartum information

During onboarding you provide your pregnancy stage, due date, and — after birth — your baby's birth date, so recommendations match your stage. Apple classifies pregnancy and childbirth information as sensitive; it is stored against your account and used only to personalize the app.

Content you create

Your nightly check-in responses, gratitude entries, Sleep Plan inputs, newborn-strategy answers, and any posts you make in the in-app community. Community posts are visible to other members of your group; everything else is private to your account.

Subscriptions and purchases

Your subscription status and purchase history are processed through Apple and RevenueCat to manage your Solas Premium subscription and free trial. Payment is handled by Apple — we do not receive or store your payment-card details.

Usage analytics

We record pseudonymous product-interaction events (for example, which features you open) through Mixpanel to understand and improve the product. We do not use a third-party crash-reporting SDK.

Diagnostics

Aggregate crash and performance diagnostics may be shared with us through Apple's standard app analytics, only if you consent to share with developers on your device. These are not linked to your identity.

The marketing site (solasmoms.com)

When you join the waitlist on this site, we collect your email address, an optional coarse wearable type (such as "Oura" or "Apple Watch"), and your browser user-agent string for spam mitigation. We use Vercel Analytics and Vercel Speed Insights for anonymous, aggregated site metrics; these set no cookies and collect no personal data. We do not use marketing cookies, ad pixels, third-party analytics SDKs, or session-replay tools on this site.

How we use your data

We use your data to provide and personalize the app, manage your subscription, understand and improve how Solas is used, and communicate with you. We do not use your data for third-party advertising and do not track you across other companies' apps or websites.

What we never do

• We never sell health or personal data.
• We never share your email with advertisers.
• We never use your health data to train AI models.
• We never track you across other companies' apps or websites.

Service providers

We share data only with processors that help us operate Solas, under contract:

• Supabase — database and authentication hosting (US region).
• Apple — payments, Sign in with Apple, and app analytics.
• RevenueCat — subscription management.
• Mixpanel — product analytics.
• Vercel — marketing-site hosting and analytics.
• Oura, WHOOP — only the wearable connections you choose to authorize.

Retention and deletion

You can delete your account at any time in the app: Profile → Delete Account. This removes your account and its associated data from our systems. For Sign in with Apple users, the app also directs you to revoke the Apple grant in iOS Settings → Apple ID → Sign in with Apple → Solas. You can also email info@circadiangroupllc.com with the subject "Delete my data" and the email associated with your record, and we will confirm and process the deletion within a reasonable period.

Data location

Account and app data are stored on Supabase (US region). Some service providers listed above may process data in the United States.

Children

Solas is not directed at children under 13 and does not knowingly collect data from them.

Changes

We will update this page when our practices change and note the revision date at the top.
