How to keep your period tracker records when moving to a new iPhone
A period calendar is only useful if the dates you saved stay with you. MiniCycle does not require an account, so moving to a new iPhone should be treated like any other local app data migration: make the transfer deliberately, then verify the records before erasing the old phone.
Start with the right expectation
MiniCycle keeps cycle records on your device instead of uploading them to a MiniCycle account. That keeps the app simple and private, but it also means the iPhone transfer process matters. If you change phones, do not assume a fresh App Store install will recreate your history by itself.
Use Apple's transfer or backup flow
When you are setting up a new iPhone, Apple documents two common paths: Quick Start device transfer and restoring from an iCloud or computer backup. Use one of those migration paths before you rely on the new phone as your main device.
If you use a computer backup, follow Apple's current backup guidance and pay attention to encryption when the backup includes sensitive health-related data from the device. Apple's support documents are the source of truth for the current setup screens and requirements.
Check MiniCycle before erasing the old iPhone
After the new iPhone is set up, open MiniCycle and review the calendar before wiping the previous device. Check that recent period starts, end dates, notes, statistics, and widget state look reasonable. This is faster than trying to reconstruct dates later from memory.
If you are switching from another period app
MiniCycle currently focuses on a lightweight calendar experience rather than account-based importing from other period trackers. If your previous app offers an export, keep that file or screenshot for your own records, then manually enter the period starts you trust most. Recent start dates are the most important inputs for MiniCycle's cycle estimates.
A practical migration checklist
Before changing phones: make a current backup or start a direct transfer, keep the old iPhone nearby, install or open MiniCycle on the new phone, verify the calendar, and only then erase or trade in the old device. The checklist is simple because the risk is simple: local records are easiest to protect before the old device is gone.
