This policy applies to the iOS app Dayflow Calendar (“the app” or “Dayflow”) made by the Studio and to this website.

At a glance

1. What we process and why

A. Information processed only on your device

The following information is processed only on your device. The Studio does not receive it and cannot see it.

Calendar events
Events from the calendars registered on your device, such as iCloud and Google (title, date and time, location, notes, URL, repeat and alert settings), are used to display the calendar, add, edit, and delete events, and search. They are processed only if you grant calendar access. Events are stored in the iOS Calendar, and syncing with other devices follows the policies of the calendar service you connected to your device (Apple, Google, and so on).
Shift and attendance data
Your shift schedule (work pattern, teams, shift types), per-date shift changes, clock-in/clock-out and break times, and leave records and settings are used to display the schedule, total work hours, and calculate leave.
App settings
Display settings, calendar and widget designs, date outlines, and restorable copies of deleted events kept in Deleted Events are used to provide app features.
Stickers
The position and appearance of emoji and illustration stickers you place on the calendar, image stickers you cut out from photos or paste in, and handwriting are kept in the app’s storage on your device and shown on the calendar and widgets. Cutting a subject out of a photo uses the iOS photo picker and on-device image processing only; the app does not request access to your whole photo library.
Saving to Photos
When you use Share Schedule to save your shift schedule as an image in the Photos app, the app asks only for iOS permission to add photos. It does not request permission to read your photo library, and the saved image stays only in your Photos app.
Free trial start date
To count your free trial, the app saves the trial start date in your device’s Keychain. If no date is saved yet (the first time you open the app, or after the device was erased), the app saves the date Apple provides for this Apple ID’s first download of the app, or the day you open the app if that date is not available. The Keychain date stays on your device even if you delete the app, so reinstalling does not restart the trial. This date is never sent off your device.
Notifications
Every notification the app sends is a local notification scheduled on your device, including the daily event summary, the badge count, reminders 3 days before your free trial ends and on its last day, and notices timed to how long you have used the app. The app does not use server-sent push notifications.
Weather and location
If you turn on the weather display, the app saves the name and coordinates of one place you choose (by searching for a city or using your current location once) in the app’s settings on your device, and sends those coordinates to Apple’s WeatherKit to fetch a ten-day forecast. The app does not track your live location. The saved place is removed when you change it or delete the app. The Studio never receives your location. Apple’s handling is governed by Apple’s Privacy Policy. When you search for a city by name, the text you type is sent to Apple through Apple Maps search (MapKit) to get results. When you use your current location, its coordinates are sent to Apple to look up the place name. The Studio never receives your search text or these coordinates.
Widgets
So the Home Screen and Lock Screen widgets can display them, a few months of events, a shift summary, and stickers are written to the app’s shared storage on your device. Only the app and its widgets read this storage, and it never leaves your device.
Backup files
When you create a backup in Settings, the app builds a file on your device containing your shift schedule, work-time and break records, leave records, stickers and their images, and app settings. You choose where to save it in the Files app; if you choose iCloud Drive, it is uploaded to your own iCloud. The Studio never receives this file. Backup files you have already saved remain after you delete the app, so delete them yourself if you no longer need them.

B. Information you send us

Contact email
Your email address, your name (if your mail app includes it), the content of your message, and the app version and iOS version that the app pre-fills in the message body are used to answer your inquiry and to investigate and fix problems. You can delete the app and iOS versions before sending.

C. Purchases

The Lifetime Pass is handled through Apple’s App Store in-app purchases. The free trial is not an in-app purchase; it starts without any payment or purchase step. The Studio does not receive payment information such as your name, payment method, or Apple ID. The app only checks the purchase records Apple provides on your device to determine whether you have the pass. Your free trial is counted from the date described under “Free trial start date” above. Payment information is handled under Apple’s Privacy Policy.

2. How long we keep it

3. Sharing with third parties

The Studio does not share your personal information with third parties, except where required by law.

4. Processors and international transfers

The Studio does not outsource the processing of personal information. However, because contact emails are received through Apple’s iCloud Mail, they are stored on Apple’s servers.

Recipient
Apple Inc. (privacy inquiries)
Countries
The United States and other countries where Apple operates data centers
Information transferred
The email address, name, message content, and app/iOS versions contained in your contact email
When and how
Transmitted over the network when you send a contact email
Purpose

Retention
The same as the contact email retention period in section 2
How to opt out
No transfer takes place if you do not contact us by email. This does not affect your use of the app.

5. How we delete information

Contact emails whose retention period has ended are permanently deleted from the mailbox so they cannot be recovered, and they are never printed or kept on paper. The Studio does not store information from your device, so you can delete it yourself in the app or by deleting the app. The free trial start date saved in the Keychain, however, is removed when the device is erased.

6. Your rights

7. How we keep information safe

8. Cookies and tracking

The app does not use cookies, the advertising identifier (IDFA), or analytics or tracking tools. This website does not use cookies or visitor analytics either. Cloudflare, which serves the website, and Google Fonts, which provides the fonts, may process your IP address and browser information when you connect; the Studio does not receive this information.

11. Changes to this policy

If it changes, we will announce the change on this page at least 7 days in advance, or at least 30 days in advance for changes that are unfavorable to users. The Korean version of this policy is the authoritative text; this translation is provided for convenience.

This revision (effective October 19, 2026): added a note that your search terms are sent to Apple Maps search when you look up a weather location by city name, and that your coordinates are sent to Apple to look up the place name when you use your current location; added the photo saving item (Add Photos permission); expanded the notifications item to cover other local notifications such as free trial ending reminders; and added the Add Photos permission to the list of permissions you can turn off. The previous policy (effective September 28, 2026) continues to apply until this revision takes effect.
