Privacy Policy

Effective June 2026 · Duane is published by Boot Canyon Advisory LLC.

The short version Duane keeps almost everything on your device. There are no accounts to create, no ads, no analytics or tracking SDKs, and we don't sell your data. Your location is used on your phone to find markers nearby — it isn't stored on our servers or shared with anyone.

Location

Duane uses your location to find Texas historical markers near you and to know when you're approaching one while driving. This happens on your device. We do not store your location on our servers, build a history of where you've been, or share it with third parties. You can turn location off at any time in iOS Settings — the rest of the app (browsing the map and tags) still works.

What's stored on your device

The stories you've heard, the stops you've saved, and your "Tune Duane" preferences (voice, story style, and similar) are stored only on your iPhone. We can't see them. Deleting the app, or using Reset all progress in Settings, removes them.

Audio narration

Duane's narrations stream from our content delivery network. A request includes the marker's ID and the standard technical information that accompanies any internet request (such as your device's IP address, which our hosting providers may log briefly for security and reliability). These requests do not include your name, an account, or any identifier that ties the request to you. Audio you've heard may be cached on your device so it can play back offline.

Notifications

If you allow notifications, Duane may let you know about a story nearby or a "this day in Texas history" marker. These alerts are generated on your device and don't send personal information to us. You can turn notifications off any time in iOS Settings.

The website and early-access list

If you sign up for early access on heyduane.com, we store the email address you provide (with an email service provider) so we can send you launch updates. We don't use it for anything else, and you can unsubscribe from any message.

No tracking or advertising

Duane contains no advertising, no third-party analytics or tracking SDKs, and no cross-app or cross-site tracking. We don't sell or rent personal information.

Children

Duane is a general-audience app and isn't directed to children under 13. We don't knowingly collect personal information from children.

Your choices

Turn location or notifications on or off in iOS Settings.
Reset your saved and heard stories in the app's Settings, or delete the app entirely.
Unsubscribe from emails using the link in any message.
Email us with any question about your data.

Changes

If we update this policy, we'll post the new version here and update the effective date above.
