Crookneck Consulting LLC (that's us) publishes photography apps including The Photographer's Ephemeris, The Photographer's Ephemeris 3D and The Photographer's Transit.
We are also partners with Skyfire Services LLC, who offer Skyfire, a forecasting service for photographers that predicts great sunrises and sunsets. Skyfire is offered as an optional subscription with The Photographer's Ephemeris on iOS (and a standalone Android app is coming soon, which will be published by Skyfire Services LLC).
If you sign up for Location Synchronization within The Photographer's Ephemeris, or for Skyfire, you will be asked to create a Crookneck Photo Apps account. We use this account to store your basic account information, your subscription details and any saved locations from TPE.
You can manage your account from the Account page within TPE for iOS, Skyfire for Android (coming soon) and from the Locations page of the TPE web app.
If you no longer need an account, you can delete it, but please note this is irreversible and you will lose access to any active subscriptions and any saved locations associated with the account.
If you have any questions or concerns, please contact us by opening a support request using the link on this page.
