Privacy Policy

Last updated: 2026-10-06

Short version: The app collects nothing automatically. Your boards stay on your devices and in your own iCloud. DECEMBER CAPITAL does not receive, see or store them. There is no account, no analytics, no tracking and no ads.

Who is responsible (controller)

The controller is DECEMBER CAPITAL, SARL (EURL) with share capital of €1,000, head office 14 rue de la Source, 75016 Paris, France, SIREN 898 168 497, RCS Paris. Contact: support@getkankan.com. In this policy, "we", "us" and "our" mean DECEMBER CAPITAL.

What the app handles, and where it lives

KanKan handles the content you create: boards, cards, notes, checklists, tags, due dates and settings. It also keeps a card activity log, and on Mac the Agent Access token names and records (the app stores only a hash of each token, never the token itself) and an audit log of what agents did. This data is stored on your device. If you turn on iCloud sync, it is also stored in your own private iCloud (see below). In the App Store privacy details, KanKan is listed as "Data Not Collected". This means the app collects nothing automatically. Reports and emails are only what you choose to send.

The app also keeps diagnostics on your device: a trail of recent actions, a record of the last session and a log of hangs. They are in the app's Application Support folder. They stay on your device unless you send a report.

What we collect

From the app: nothing. DECEMBER CAPITAL does not receive your board content, your device details or your usage. KanKan has no analytics, no tracking, no advertising and no third-party SDKs. The app and this website do not use cookies.

The only data DECEMBER CAPITAL receives is what you choose to send by email (see "Support and problem reports").

iCloud sync

Sync is optional and off until you turn it on. When on, KanKan stores your data in the private database of your own iCloud account. That data belongs to you and is handled by Apple under your Apple Account. DECEMBER CAPITAL has no access to it. Apple's own privacy policy applies to iCloud.

Subscriptions

KanKan Unlimited is an auto-renewing subscription. Apple processes the payment. DECEMBER CAPITAL does not receive your payment details or your Apple Account details. DECEMBER CAPITAL sees only aggregate sales and subscription reports that Apple provides. KanKan checks your subscription status with Apple, on your device, to unlock features.

Agent Access (Mac only)

Agent Access is optional. It is a local server that runs on your Mac only, while the app is open. It lets AI assistants on that same Mac read and change your board. It uses access tokens that you create. You can revoke them at any time. KanKan accepts these connections from that Mac only.

Agent Access sends nothing to DECEMBER CAPITAL or to any server. If iCloud sync is on, your token names and the agent activity log (which includes card titles the agent touched) sync to your own private iCloud like your boards.

If you give a token to an assistant, that assistant can read the board content the token allows. What it does with that content is governed by that assistant's provider and settings, not by KanKan. Give a token only to software you trust.

Notifications

Reminders and the daily summary are local notifications. Your device schedules and shows them. They are not sent from a server. The app asks your permission first. You can turn notifications off in the system Settings.

Support and problem reports

The "Report a problem" feature in the app shows the report to you first. It does not send anything by itself. The report leaves your device only if you choose to email it to us. The report can contain:

• app version and build, platform, system version, device model and locale;
• the data-format fingerprint and store type;
• whether iCloud is available, and sync status and error codes;
• whether the last session ended in a crash or hang, with hang records;
• counts (for example of boards and cards);
• a technical event log: up to 200 recent app events with times (operation names, positions and counts, navigation and drag events, app launch, foreground and background, hang and report events);
• the kind, source and time of the 20 most recent entries in your card activity log, never their text;
• recent agent tool names, outcomes and times.

It never contains card or board titles, notes or checklist text.

If you email us, we receive what you send: your message, your email address and the report if you include it. We use it only to help you and to fix problems. We do not use it for marketing. Support emails are deleted 12 months after the last message in the conversation. You can ask us to delete them sooner.

There is no automated decision-making or profiling.

Who processes data (recipients)

• Apple: iCloud (your private sync data), the App Store and subscriptions.
• Google (Gmail): our email inbox, if you email support.
• Squarespace and its forwarding provider Mailgun: they forward email sent to support@getkankan.com to our inbox.
• GitHub (GitHub Pages): hosts this website. It logs visitor IP addresses for security.

International transfers (Article 13(1)(f)). Several of these providers are in the United States. Transfers rely on the EU-US Data Privacy Framework where the provider is certified, and on standard contractual clauses otherwise.

The page Report a problem runs only in your browser. It has no server and sends nothing.

Legal basis (GDPR)

For support emails, the basis is our legitimate interest in answering you and fixing problems (GDPR Article 6(1)(f)), or your request (Article 6(1)(b)) where it relates to your use of the app. For the app itself, we process no personal data.

Children

KanKan is a general productivity app. It is not directed at children, and DECEMBER CAPITAL does not knowingly collect data from anyone, including children.

Deletion

• On iPhone, deleting the app removes its data from the device. On Mac, moving the app to the Trash does not remove its data. To remove it, delete the folder ~/Library/Containers/com.chrisbates.kankan (in Finder: Go, Go to Folder). Export a backup first if you want to keep your data.
• Turning off iCloud sync stops syncing. To delete the app's data from iCloud: Turn off iCloud Sync on all your devices and reopen KanKan. Then choose Settings → Reset iCloud Data…. You can also manage it in your Apple Account and iCloud settings.
• Support emails are deleted 12 months after the last message in the conversation. To delete one sooner, write to support@getkankan.com. We will delete it and confirm.

Your rights

Under the EU GDPR you have the right to access, correct, delete and move your data, and to object to or restrict its use. Because DECEMBER CAPITAL holds no copy of your board data, you use most of these rights directly in the app and in your iCloud settings. For emails you sent us, write to support@getkankan.com.

You have the right to complain to a supervisory authority. In France this is the CNIL (Commission Nationale de l'Informatique et des Libertés): cnil.fr. You may also complain to the authority in the EU country where you live or work.

Changes to this policy

If this policy changes, we will update this page and its "Last updated" date. If a change affects how your data is handled, we will say so in the app update notes.
