This Privacy Policy explains how Krepel Studio handles information in World Clock: Time Difference (the “App”), an Android application for viewing local dates and times around the world, comparing time zones, saving groups of cities, displaying a selected clock in Android notifications, and setting optional one-time time-zone reminders.
The App is designed to provide its core clock and city-search features locally on your device. It does not require a Krepel Studio account, access to your physical location, or a Krepel Studio cloud service.
Depending on the features you use, the App stores or processes the following information locally:
Cities and time zones you select, saved groups of cities, their order, and your preferred reference city for time comparisons.
Local dates and times used to display clocks and calculate time differences. Calculations use your device's clock and time-zone rules.
Settings such as your language, light or dark theme, analog or digital clock preference, and haptic feedback preference.
If you enable a notification clock, your selected city or saved group, its enabled state, and the locally stored status of the one-time Free activation.
If you create a reminder, the selected city or time zone, requested local date and time, scheduled moment, and reminder status.
Information needed to recognize whether Lifetime Pro features are available, including locally handled purchase status.
These details are used to provide the features you choose. The App is not designed to send your saved cities, time comparisons, preferences, or reminder details to Krepel Studio servers.
Searching for or selecting a city does not mean that the App determines or tracks your current physical location.
The App uses a locally included geographical catalog based on GeoNames data and Android's time-zone information to display cities and calculate local time. City searches and clock calculations are designed to work without an internet connection and without sending your search terms to GeoNames.
GeoNames provides geographical data under a Creative Commons Attribution license. More information is available at https://www.geonames.org/ and https://creativecommons.org/licenses/by/4.0/.
Internet connectivity may be used when you choose to view, purchase, verify, or restore Lifetime Pro through Google Play Billing. The basic world-clock functionality does not require a connection to a Krepel Studio server.
The App only uses notification-related functionality when you choose to enable it:
Notification permission (POST_NOTIFICATIONS, Android 13 and later): Allows the App to display one selected information clock in the notification shade and, for eligible Pro users, one-time reminder notifications.
Alarms and reminders access (SCHEDULE_EXACT_ALARM, where required): Allows the App to request precisely scheduled one-time reminders for a chosen local time. Android may require you to grant this access separately in system settings.
Receive boot completed (RECEIVE_BOOT_COMPLETED): Allows the App to attempt to restore eligible pending reminders after your device restarts, subject to Android restrictions.
The information clock is intended to be silent. One-time reminders use a separate notification channel with sound, subject to your device's volume, notification, and Do Not Disturb settings. Android controls whether notifications appear on the lock screen and what content is visible there.
You may decline or revoke notification and alarm access in Android settings. If access is unavailable, the affected notification or reminder feature may not work, but basic city search and time comparison remain available.
The App's agreed features do not require permission to access GPS or other device location, contacts, camera, microphone, SMS, call history, files, Accessibility Service, or the contents of other apps' notifications.
The App offers an optional one-time Lifetime Pro purchase through Google Play Billing. Google handles payment processing under its own terms and privacy practices.
The App may obtain purchase-related information from Google Play, such as the product identifier, purchase status, and purchase token, to activate, verify, or restore Pro access. Krepel Studio does not receive your full payment-card details through the App.
For information about Google's processing of purchase and payment information, see https://policies.google.com/privacy.
The App is designed without advertising, Google AdMob, or third-party advertising and behavioral analytics SDKs. Krepel Studio does not use your saved cities, clock preferences, or reminder details for advertising profiles or sell that information to advertisers.
Google Play Billing is used for optional purchases. Android provides the system clock, time-zone rules, notification delivery, alarms, and optional operating-system backup services. GeoNames data is included as a geographical reference rather than queried using your searches.
If the services or SDKs included in a future release change, this Privacy Policy will be updated accordingly.
If you contact Krepel Studio by email, we receive your email address and any information you choose to include in your message. We use that information to respond to your request and provide support.
Your email provider may process the correspondence according to its own privacy practices. We do not ask you to provide personal information to use the App's clock features.
Your saved cities, groups, preferences, notification selection, and reminder records are intended to remain in the App's local storage until you change or delete them, clear the App's data, or uninstall the App. You can remove saved groups and reminders using the available App controls.
You can erase locally stored App data through Android's application settings or by uninstalling the App. Depending on your device and backup configuration, Android or Google may maintain copies of eligible app data through operating-system backup features. Such backups are controlled by the platform and its settings, not by a Krepel Studio cloud account.
Google Play may retain purchase records according to Google's policies, even if you uninstall the App. Removing local App data does not cancel or erase Google Play transaction records.
If you contact us for support, you may request deletion of the correspondence that Krepel Studio controls, subject to applicable legal or necessary operational retention requirements.
The App relies on Android's app-isolation, storage, and permission mechanisms to help protect locally stored information. Optional system access is used only for the features that require it. Payment processing is handled through Google Play.
No device, software, or storage system can be guaranteed completely secure. Krepel Studio aims to limit access to the information necessary for the App's functionality.
You can choose which cities and groups to save, select the clock display style, manage reminders, disable the information clock, and control notification permissions through Android settings. You may also clear the App's local data or uninstall it.
For privacy questions or requests relating to information you have provided directly to Krepel Studio, contact Krepelstudio@gmail.com. We will review requests in accordance with applicable law.
The App is not designed to request personal information from children. It does not require users to register an account or submit personal details to use world-clock features. If you believe a child has provided personal information to us through a support message, please contact us.
We may update this Privacy Policy if the App's functionality, Android permissions, included services, or legal requirements change. The updated policy will include a revised “Last updated” date and will be made available through the App's Privacy Policy link.
