Privacy Policy

Faraday is built around one principle: your data stays on your device. We do not sell your data, we do not run analytics on your usage, and we do not know what devices you scan, what schedules you set, or how long your detox sessions are. The only data that ever leaves your phone is what's needed to authenticate your account and verify your subscription — handled entirely by Apple and Google.

Faraday is published by Sonia Labs Inc., a Canadian corporation. When this policy refers to “we,” “us,” or “our,” it means Sonia Labs Inc..

Account data

When you sign in with Apple or Google, we receive a unique user identifier from that provider (e.g., an Apple ID or Google UID). If you sign in with Google and choose to share your email address, we receive that email. We use this identifier solely to associate your subscription status with your account. We do not collect your name, phone number, or payment information — Apple handles all billing.

On-device data (never transmitted)

The following data is created and stored exclusively on your device using Apple's SwiftData framework. It never leaves your phone:

• Bluetooth scanner results and exposure scores
• Detox session history and duration
• Schedules and reminders you configure
• Your detox streak and usage statistics

Deleting the app permanently deletes all of this data. There is no server-side backup.

Subscription data

Faraday uses Apple's StoreKit framework to manage subscriptions. Apple processes all payments and provides us with a receipt that confirms your subscription status. We do not receive or store any payment card or financial information.

Crash and diagnostic data

If you have opted in to sharing analytics with developers in your iOS settings, Apple may provide us with anonymised crash reports. These contain no personal information and are used solely to fix bugs.

We use the following third-party services:

• Firebase Authentication (Google LLC)— manages sign-in via Apple and Google. Firebase's privacy policy is available at firebase.google.com/support/privacy.
• RevenueCat, Inc. — manages in-app subscription state, receipt validation, and entitlement verification. RevenueCat receives your Apple ID (anonymised), your App Store receipt, and basic device metadata (platform, app version) to confirm your subscription status. RevenueCat does not receive payment card information. Their privacy policy is available at revenuecat.com/privacy.
• Apple Sign in & StoreKit (Apple Inc.)— manages Apple ID authentication and in-app subscription billing. Apple's privacy policy is available at apple.com/legal/privacy.

We do not use any third-party analytics, advertising, or tracking SDKs.

We use your account identifier to:

• Verify that you have an active subscription
• Restore your subscription on a new device

We do not use your data for advertising, profiling, or any other purpose.

Your account record (user identifier and subscription status) is retained for as long as your account is active. If you wish to delete your account and all associated data, contact us at hi@sonialabsinc.com and we will remove your record within 30 days. On-device data is deleted immediately when you uninstall the app.

Faraday is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will delete it promptly.

Depending on your jurisdiction, you may have the right to access, correct, or delete personal information we hold about you, or to object to how we process it. To exercise any of these rights, contact us at hi@sonialabsinc.com.

We may update this policy from time to time. We will notify you of material changes by updating the effective date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
