Privacy Policy

Last updated: August 11, 2026

Overview

ShiftChain runs entirely on your device. There are no accounts, no servers, no analytics, and no advertising. Nothing you enter or that ShiftChain reads ever leaves your iPhone.

Calendar access

ShiftChain requests access to your calendar so it can find the shift events you already keep there. It uses event titles, start times, and end times to work out which shifts you are working and when each alarm should ring.

Calendar events are read on your device only
ShiftChain never creates, edits, or deletes calendar events
Calendar data is never transmitted anywhere

You can revoke calendar access at any time in Settings → Privacy & Security → Calendars → ShiftChain. Without it, ShiftChain cannot detect your shifts.

Alarms and notifications

ShiftChain uses Apple's AlarmKit to schedule alarms, and notifications to show the alarm chain on your Lock Screen as a Live Activity. Alarms and their Live Activity content are handled by iOS on your device.

Data storage

Your shift types, routines, locations, keywords, and per-day adjustments are stored locally on your device using Apple's SwiftData framework. If you have iCloud Backup switched on, this data is included in your device backup, which is encrypted and controlled by Apple, not by us.

Deleting the app deletes this data.

Data we collect

None. ShiftChain collects no personal data, does not track you, and contains no third-party analytics, advertising, or tracking SDKs.

Children

ShiftChain is a general-purpose utility and is not directed at children. It collects no data from anyone, including children.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new “Last updated” date.
