CalendarBell Privacy Policy

Last updated: June 25, 2026

CalendarBell (the "App") respects your privacy and limits the information it handles to what is necessary to provide the App. This Privacy Policy explains how information is handled in the App.

The App is provided by a service provider residing in Japan. This Privacy Policy is prepared on the basis of Japanese law, including Japan's Act on the Protection of Personal Information.

If there is any inconsistency or conflict between the Japanese version of this Privacy Policy and any translation, the Japanese version will prevail.

1. Information We Handle

The App may access and store the following information on your device with your permission.

1.1 Calendar information

If you grant calendar access, the App reads calendars and events on your device through EventKit. This may include event identifiers, titles, start times, end times, all-day status, calendar names, calendar identifiers, and calendar colors.

This information is used to provide App features such as event display, alarm creation, automatic alarm registration, excluded-event management, and Live Activity display.

As of the v1 release, the App is not designed to send calendar event titles, event times, or calendar contents to the service provider's server.

1.2 Alarms, settings, and in-app data

The App stores alarms created or configured by you, links between events and alarms, excluded events, per-calendar settings, notification settings, Live Activity settings, onboarding completion state, and similar data in local storage on your device.

This information is used to provide, display, synchronize, restore, and maintain App features and settings.

1.3 Purchase and subscription information

The App uses Apple's StoreKit and RevenueCat to process in-app purchases and confirm Pro entitlement status.

RevenueCat may receive information such as an anonymous app user ID, purchase, restore, and subscription status, product IDs, receipts or purchase tokens, and technical information about the device or OS. This information is used to process purchases, confirm subscription status, restore purchases, prevent fraud, and operate billing features.

Payments are processed by Apple. The service provider does not receive your credit card number or other payment method details.

1.4 Support inquiries

If you contact us by email or another method, we may receive the information you provide, such as your email address, inquiry details, device, OS, and App version. This information is used for support, identity confirmation, investigation, and quality improvement.

1.5 Website access information

The App's support page, Terms of Use, Privacy Policy, and related web pages are expected to be published using Cloudflare Pages. Depending on Cloudflare's services, information such as IP address, browser, access time, and referrer may be recorded in access logs. This information is used to provide the website, maintain security, and investigate issues.

2. Purposes of Use

The App uses information for the following purposes:

• displaying calendar events;
• creating, managing, updating, and deleting alarms related to events;
• automatic alarm registration, excluded-event management, and settings storage;
• providing notifications, AlarmKit, Live Activities, App Intents, and related features;
• confirming Pro features, purchases, restores, and subscription status;
• investigating issues, responding to inquiries, and improving quality; and
• complying with laws, terms, and App Store requirements.

3. Third-Party Services

The App uses the following third-party services.

3.1 Apple

The App uses Apple-provided features such as iOS, EventKit, AlarmKit, notifications, Live Activities, StoreKit, and App Store in-app purchases. Please refer to Apple's privacy policy and related terms for Apple's handling of information.

4. Sharing with Third Parties

The App does not provide user information to third parties except in the following cases:

• when you consent;
• when information is sent to or processed by Apple, RevenueCat, or Cloudflare as necessary to provide App features or deliver the website;
• when required by law;
• when necessary to protect the life, body, property, or rights of you or a third party; or
• when information is transferred as necessary in connection with business succession, merger, transfer, or similar transactions.

5. Retention and Deletion

Local data stored on your device, such as alarms, settings, excluded events, and calendar-related data, may remain until you delete the App, delete device data, or delete or change the data within the App.

Purchase and subscription information sent to RevenueCat is retained according to RevenueCat's policies and agreements. Purchase and payment information handled by Apple is retained according to Apple's policies. Information received for support inquiries is retained for the period necessary to respond and for any period required by law.

If you would like to request disclosure, correction, addition, deletion, suspension of use, erasure, or suspension of third-party provision of personal information held by the service provider, contact us using the details below. We will verify your identity and respond within a reasonable scope in accordance with applicable law. Local data on your device may be deleted by deleting the App or through device settings.

6. Permission Controls

You can change calendar, notification, and other permissions at any time in the iOS Settings app. If permissions are revoked, some App features may become unavailable or limited.

Notification permission is optional and is not required to use the App itself.

7. Analytics, Advertising, and Tracking

As of the v1 release, the App does not use advertising tracking and does not use advertising networks.

If crash reporting, usage analytics, advertising, or external server integrations are introduced in the future, this Privacy Policy, App Store Connect App Privacy answers, and in-app explanations will be updated before introduction, and user consent will be obtained where required.

8. Security

The App limits information handling to what is necessary and uses local device storage, iOS permission controls, and security features provided by Apple and third-party services to help protect information.

However, no method of storage or transmission can be guaranteed to be completely secure. Device lock settings, OS updates, and Apple Account management by users are also important.

9. Minors

If a minor uses the App, they should do so with consent from a parent or guardian. The App is not primarily directed to children.

10. International Transfers

In connection with RevenueCat, Cloudflare, and other third-party services, purchase and subscription-related information, website access logs, and technical information may be processed or stored on servers outside Japan.

11. Changes to This Policy

This Privacy Policy may be changed as necessary. Important changes will be announced in the App, on the website, or by another appropriate method.
