DSober is a designated-driver coordination app operated by Kappa Theta Pie ("we," "us"). It helps members of our chapter request rides, volunteer as designated drivers, and complete a brief sobriety check before driving. This policy explains what we collect, why, and the choices you have.
Information We Collect
Account & profile
- Email address and password (for sign-in).
- Name, date of birth (and the age derived from it), and gender.
- Phone number, used so a driver and rider can contact each other for a ride.
- An optional profile photo.
Designated-driver information (only if you volunteer to drive)
- Vehicle make, model, and license plate.
- Identity verification through Stripe Identity, which checks a government-issued ID and a matching selfie. Stripe processes and stores those verification images on our behalf; DSober receives only the verification result and a reference identifier, not the ID document itself. (Members who verified under an earlier version of the app may still have a driver's-license photo stored privately in their account.)
Sobriety verification (SEP)
Before each driving session, and once during onboarding to establish a baseline, we collect a short reaction-time result, a brief voice recording of a spoken phrase, and a selfie. These are compared against your baseline to check fitness to drive. Results may be shared with your chapter's administrators (see below).
Location
With your permission, we use your device's precise location while the app is in use to show nearby designated drivers and your distance from them during an event. We do not track your location in the background.
Usage & device
- Events you join, ride requests, driving sessions, and notification history.
- A push-notification token plus your device name, operating system, and app version, used to deliver notifications.
- If crash reporting is enabled, diagnostic crash and error data (no message content) to help us fix bugs.
How We Use Your Information
- To operate the core service: matching riders with drivers, running events, and coordinating rides.
- To run the sobriety check and notify chapter administrators of a failed check or a revoked driving status, for safety.
- To send you notifications you've opted into (and critical safety alerts).
- To secure accounts and prevent automated abuse, including bot detection during sign-in and sign-up.
We do not sell your personal information or use it for advertising.
How Information Is Shared
- Within your chapter. Other members in your chapter can see a driver's name, photo, vehicle, and (during a ride) phone number. Your chapter's administrators can see members' driver information and sobriety-check results for safety oversight.
- Service providers. We use Supabase (database, authentication, and file storage), Expo (push notification delivery), Stripe (identity verification of designated drivers), hCaptcha (bot and abuse prevention on sign-in and sign-up, which processes device and interaction signals), and—if enabled—Sentry (crash diagnostics). They process data only to provide these services.
- Legal. We may disclose information if required by law or to protect someone's safety.
Data Retention & Deletion
We keep your information for as long as your account is active. You can permanently delete your account at any time from Profile → Delete My Account. Deletion immediately removes your profile, ride and driving history, sobriety-check records, and uploaded photos and audio from our active systems; any residual copies in routine encrypted backups are overwritten within 30 days. This action cannot be undone. Identity-verification images held by Stripe are retained and deleted in accordance with Stripe's own retention practices.
Security
Data is transmitted over encrypted connections and stored with access controls so that members can reach only the data appropriate to their role. Sensitive files (license photos, sobriety selfies and audio) are kept in private storage and served only through short-lived, access-controlled links. No system is perfectly secure, but we take reasonable measures to protect your information.
Biometric Information
The sobriety check uses a selfie and a short voice recording, and designated-driver verification uses a selfie matched to a government-issued ID (handled by Stripe Identity). Depending on your state, some of this may be treated as biometric information. We obtain your consent before collecting it, use it solely to verify identity and screen fitness to drive, do not sell it or use it for advertising, and delete sobriety-check selfies and audio when you delete your account (identity-verification images are handled by Stripe under its retention practices).
We operate in Virginia, whose Consumer Data Protection Act treats biometric identifiers as sensitive data that we process only with your consent; Virginia has no separate biometric statute and provides for enforcement by the state Attorney General. If you use DSober from a state with a dedicated biometric-privacy law — for example Illinois (BIPA), Texas (CUBI), or Washington — the additional protections of that state's law may also apply to you.
Age Requirement
DSober is intended for members of our organization who are of legal age and is not directed to children under 13. Because the app is used in contexts involving alcohol, it is rated for adults; you must comply with all applicable laws regarding alcohol.
Your Choices
- Manage which notifications you receive in Notification Settings (some critical safety alerts cannot be turned off).
- Grant or revoke camera, microphone, photo, and location permissions in your device settings.
- Access or delete your data using the in-app account-deletion tool, or by contacting us below.
Changes to This Policy
We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
