Calendar Alarm

Date-Based Alarms & Sleep

Privacy Policy

Effective Date: October 26, 2026

William Cheung ("we", "us", or "our") built the Calendar Alarm app as a Commercial app. This SERVICE is provided by us and is intended for use as is.

This page is used to inform visitors regarding our policies with the collection, use, and disclosure of Personal Information if anyone decided to use our Service.

1. Data Collection and Use

We do not collect, store, or transmit any personal data.

Calendar Alarm is designed with strict privacy in mind. We do not require you to create an account, we do not track your location, and we do not collect any analytics or usage data. Everything you do within the app remains entirely private to you.

2. Local Storage

All data created within Calendar Alarm—such as your scheduled alarms, custom labels, sleep music preferences, and notification settings—is saved entirely locally on your device's internal storage (via standard iOS APIs like UserDefaults).

This data never leaves your device and is never uploaded to any external servers or third-party databases. If you delete the app from your device, all associated data is permanently erased.

3. Device Permissions

To function properly, Calendar Alarm requests the following standard iOS permissions:

Notifications: We request notification access strictly to alert you when an alarm is triggered.
Audio/Media: We use the device's audio sessions to play alarm sounds and sleep music. We may adjust your media volume temporarily to ensure your alarm is heard, but this is handled entirely locally on the device.

We do not use these permissions to gather or transmit information.

4. Third-Party Services

Calendar Alarm does not use any third-party analytics, tracking, or advertising frameworks (such as Google Analytics or Facebook SDK). There are no third-party services collecting data behind the scenes.

5. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page. These changes are effective immediately after they are posted.
