Privacy Policy — Effective July 14, 2026
ShredCast ("ShredCast," "we," "us") is an iOS app operated by Jonathan Carden, an individual developer. This Privacy Policy explains what information ShredCast collects, how it is used, and the choices you have. By using ShredCast, you agree to the practices described here.
ShredCast is developed and operated by Jonathan Carden. There is no separate corporate entity. Contact for all privacy questions: jon.carden@gmail.com.
ShredCast does not require an account and does not collect your email address in-app. We collect:
When you submit a photo, it is sent over an encrypted connection through our server proxy to OpenAI's API. This is done solely to (a) estimate a body-fat range and (b) generate your milestone images.
OpenAI's API terms prohibit using data submitted via the API to train their models. We do not retain your photos on our server after processing — once a response is generated and returned to your device, the photo is discarded server-side.
Your original photos and any AI-generated milestone images are stored locally on your device, protected by iOS data protection (device encryption). We do not keep a copy of these images on our servers. Deleting a photo or generated image within the app — or deleting the app itself — removes that data immediately from your device. Because we do not retain a server-side copy, deletion on-device is complete deletion.
ShredCast is intended for users 18 years of age or older. We do not knowingly collect or process photos of minors. The app includes checks designed to decline analysis when a minor is suspected in a submitted photo.
Photos and generated images: retained only on your device, for as long as you keep them there. Anonymous device identifier, purchase status, and anonymous usage analytics: retained only as long as needed to operate the app and comply with Apple's subscription and analytics requirements.
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the effective date at the top of this page. Continued use of ShredCast after changes take effect constitutes acceptance of the updated policy.
