KanKan Privacy Policy

Effective: October 5, 2026

Summary

KanKan does not send what you write, or your events, to-dos and sticky notes, to the developer, and does not pass them to the ad SDK. There is no account, sign-in, subscription, in-app purchase or analytics tool, and the developer runs no server. On iPhone and iPad, a Google AdMob banner ad appears at the bottom of the screen. To show it, Google processes the information described under "Ads" below. There are no ads on Mac.

What happens to what you write

The plans you type are processed on your device by Apple Intelligence's on-device model. They don't leave your device, and no one, including the developer, can see them. The results are saved as shown in the table below.

Data that is saved

Data	Purpose	Where it's stored
Events (title, date, time)	Added to your calendar	Your Apple Calendar
To-dos (title, date, done or not)	Shown under each day	On your device and in your iCloud
Sticky notes (text, color)	Shown on the board	On your device and in your iCloud
Settings (calendars shown, target calendar)	How the app works	On your device

Calendar access

KanKan asks for full access to your calendars so it can add events and read them. Events it reads are used only to show your week and month in the app, and they don't leave your device. You can turn off access at any time in Settings (System Settings on Mac) > Privacy & Security > Calendars.

iCloud sync

To-dos and sticky notes are stored in your own private iCloud database and sync between devices that use the same Apple Account. This data lives in Apple's CloudKit private area, and the developer cannot view it. If you turn off iCloud, the data stays on your device only.

Widgets

Widgets read only a summary file that the app writes to a shared folder on your device. This file doesn't leave your device either.

Update check

To let you know when a new version is out, the app asks the public App Store lookup service (itunes.apple.com/lookup) for KanKan's latest version number, at most once a day. It sends only KanKan's app identifier and a country code, never information about you or anything you wrote. The version number it receives is stored only on your device.

Ads (iPhone and iPad)

KanKan shows a Google AdMob banner ad in one line at the bottom of the screen on iPhone and iPad. The Mac app has no ads and does not include the ad SDK.

KanKan requests non-personalized ads only. It does not request the advertising identifier (IDFA) and does not ask for App Tracking Transparency permission.
If your App Store country is the United States, KanKan also turns on Google's restricted data processing (RDP) for its ad requests. Google then limits how it uses identifiers and other data from these requests.
To show ads, the Google Mobile Ads SDK may automatically collect: device identifiers (such as an app- or developer-scoped identifier), approximate location estimated from your IP address, ad views and taps and other interactions in the app, and diagnostics such as app performance and crashes.
Google LLC processes this information to serve ads, measure ad performance and prevent invalid clicks. It may be transferred to Google servers outside your country, including in the United States.
What you write, your events, to-dos, sticky notes and calendar contents are never passed to the ad SDK.
Your choices: KanKan does not request the advertising identifier. If you turn off "Allow Apps to Request to Track" in Settings > Privacy & Security > Tracking, no app can use it. If you don't want ads, or the data collection that comes with them, you can use the Mac app, which has no ads, or delete the app.
How Google uses data: https://policies.google.com/technologies/partner-sites

Transfer to Google	Details
Recipient	Google LLC (advertising provider)
Countries	The United States and other countries where Google has servers
Information	Device identifiers, approximate location, ad views, taps and interactions, diagnostics (as listed above)
When and how	Sent over the network when an ad is requested and shown on iPhone or iPad
Purpose	Serving ads, measuring ad performance, preventing invalid clicks
Retention	As set out in Google's privacy policy

If you see an inappropriate ad, please let us know by email. We'll check it and block it.

Age range (United States)

Some US states, such as Texas, require app stores and developers to check users' ages.

If your App Store country is the United States, or KanKan can't tell your country, KanKan asks Apple whether these rules apply to your Apple Account. If they do, KanKan asks Apple for your age range through Apple's Declared Age Range feature. Apple shows the request, and you choose whether to share.
If you are under 13, KanKan shows no ads. The ad SDK isn't started and no ad is requested.
The age range is used only on your device and only while the app is open. KanKan doesn't save it and doesn't send it anywhere. The developer runs no server and never receives it.
If a parent or guardian withdraws consent, Apple stops KanKan from opening on that device. The developer holds no personal information about you, so there is nothing for us to delete. Your to-dos and sticky notes stay on your device and in your own iCloud.
Outside the United States, KanKan doesn't ask for an age range.

Sharing with third parties

KanKan does not sell your data or give it to third parties. The information described under "Ads" is collected and processed directly by Google while ads are shown. KanKan uses no analytics or crash reporting tools.

United States residents

KanKan does not sell your personal information and does not share it for cross-context behavioral advertising. Ads are not personalized, and for users whose App Store country is the United States, restricted data processing is turned on as described above.
Do Not Track: KanKan does not track you across apps or websites, so it works the same whether or not your device or browser sends a Do Not Track signal.
The developer holds no personal information about you. For data Google collects for ads, see Google's privacy policy.

Singapore (PDPA) and Hong Kong (PDPO)

Purposes: the information described under "Ads" is collected only to serve ads, measure their performance and prevent invalid clicks. Nothing else is collected by the app.
Who receives it: Google LLC, as the advertising provider. It may be transferred outside Singapore or Hong Kong, as described above. No other party receives it.
Access and correction: the developer keeps no personal information about you, so there is nothing for us to give you or correct. For data held by Google, use Google's privacy tools. Your to-dos and sticky notes are in your own iCloud and on your device, where you can view, change or delete them.
Data protection contact (including Singapore PDPA requests): taehyeonine@gmail.com

Deleting your data

Deleting the app removes the to-dos, sticky notes and settings on that device. To delete KanKan data in iCloud, go to Settings > [your name] > iCloud > Manage Storage. Events added to your calendar stay in your calendar. You can delete them in the Calendar app or in KanKan.

Children

KanKan is not directed at children under 13. Ads are requested as non-personalized only, users Apple reports as under 13 see no ads (see "Age range" above), and the developer does not collect personal information from children.

Changes to this policy

If a new feature changes how data is handled, we'll update this page, change the effective date at the top, and mention it in the app's update notes.
