Docket privacy policy

1. Summary

Docket does not collect personal data. All app data is stored locally on your device. The app does not include analytics, telemetry, advertising, or crash reporting. No account is required to use the app.

Accuracy and limitations

Docket tracks the dates and documents you enter. It does not provide tax, legal, or investment advice, does not calculate taxes, gain, or basis, and is not a substitute for a qualified intermediary or a professional advisor. The 45-day and 180-day periods are counted as calendar days from the day after the relinquished transfer, with no weekend or holiday extension, matching IRS timing; the effective deadline is the earlier of the 180-day date and your federal return due date (including extensions), which you enter. Confirm every date with your qualified intermediary and tax advisor.

2. Data Docket stores on your device

Docket stores its working data (your settings, history, and content) in the app's private storage on your device. This data never leaves your device through Docket. You can clear it at any time by clearing the app's storage in Android Settings, or by uninstalling the app.

Android's own backup system may include this data in your Google account backup if you have device backup enabled in Android Settings. That backup is controlled by Google and by your device settings; Kuroki Studio cannot access it.

3. Permissions Docket requests and why

Notifications (android.permission.POST_NOTIFICATIONS)

Requested only if you turn on deadline reminders (a Pro feature); a rationale sheet explains them before Android asks. Reminders are scheduled offline on the device. You can leave notifications off and use the rest of the app normally.

Internet (android.permission.INTERNET)

Declared by the Google Play Billing and RevenueCat libraries to verify and restore your one-time Pro purchase. Docket makes no other network calls; your exchange data never leaves the device.

Network state (android.permission.ACCESS_NETWORK_STATE)

Declared by the same billing and RevenueCat libraries to check connectivity before a purchase or restore. No information about you is collected.

In-app billing (com.android.vending.BILLING)

Declared by Google Play Billing so you can buy and restore the one-time Pro unlock through Google Play.

4. Third-party services used in Docket

Docket is a paid app. To process your purchase and restore it on reinstall or a new device, it uses Google Play Billing and RevenueCat. Where an app also has an optional feature that reaches the network (for example fetching live currency rates), the service behind that feature is listed below with the exact purpose it serves and the data it receives. No third-party services beyond those listed here are used.

Google Play Billing

Purpose: Processes the in-app purchase itself. All payment handling is performed by Google.

Data shared: Whatever Google Play collects to process a purchase on your Google account. Kuroki Studio never sees your payment details.

Their policy: https://policies.google.com/privacy

RevenueCat

Purpose: Verifies your purchase and restores it on reinstall or device change.

Data shared: An anonymous app-install identifier, the Google Play purchase token, your device platform and app version, and country (derived from IP at the time of purchase). No name, email, contacts, or location is sent.

5. Children's privacy

Docket is not directed at children under 13 (or the equivalent minimum age in your jurisdiction). Kuroki Studio does not knowingly collect any data from children. Because Docket does not collect personal data from anyone, this also applies to children who use the app.

6. Your rights

Because Kuroki Studio does not hold any personal data about you in connection with Docket, there is no personal-data record to access, correct, port, or erase on our end. To remove the app data stored on your device, clear the app's storage in Android Settings or uninstall the app. See the account and data deletion page for details.

Under Japan's Act on the Protection of Personal Information (APPI), under the EU General Data Protection Regulation (GDPR), under the UK GDPR, and under the California Consumer Privacy Act (CCPA), you have rights including access, correction, deletion, and (where applicable) the right to lodge a complaint with your data protection authority. If you have any question or request related to your privacy as it concerns Docket, contact privacy@kurokistudio.com.

7. Changes to this policy

If Kuroki Studio changes this policy, the new version will be posted at this URL and the effective date at the top will be updated. Material changes (such as introducing a new third-party service) will additionally be noted in the app's Play Store "What's new" entry.
