San Francisco Chronicle app-only customers paying through their iTunes/Apple ID account will need to subscribe to SFChronicle.com to have access.
Visit SFChronicle.com/subscribe and choose one of the available subscription options. Once you have completed your purchase, please go to your Apple ID profile through iTunes or the Settings app on your device and turn off the automatic renewal of your San Francisco Chronicle app subscription.
If you choose not to switch to a subscription that includes Unlimited Digital Access, it will not impact your ability to continue accessing the San Francisco Chronicle app.
