AKIHIRO OURA built the STAELLA app as both a Freemium and Subscription-based app. This SERVICE is provided by AKIHIRO OURA 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 decides to use our Service.

If you choose to use our Service, then you agree to the collection and use of information in relation to this policy. The information we collect is used for providing and improving the Service. We will not use or share your information with anyone except as described in this Privacy Policy.

The terms used in this Privacy Policy have the same meanings as in our Terms and Conditions, which is accessible at STAELLA unless otherwise defined in this Privacy Policy.

For a better experience while using our Service, we may require you to provide us with certain non-personally identifiable information. The information that we request will be retained on your device and is not collected by us in any way.

Log Data

We want to inform you that whenever you use our Service, in case of an error in the app we collect data and information (through third-party products) on your device called Log Data. This Log Data may include information such as your device Internet Protocol ("IP") address, device name, operating system version, the configuration of the app when utilizing our Service, the time and date of your use of the Service, and other statistics.

Cookies

Cookies are files with a small amount of data that are commonly used as anonymous unique identifiers. These are sent to your browser from the websites that you visit and are stored on your device's internal memory.

Service Providers

We may employ third-party companies and individuals for the following reasons:

  • To facilitate our Service;
  • To provide the Service on our behalf;
  • To perform Service-related services; or
  • To assist us in analyzing how our Service is used.

We want to inform users of this Service that these third parties have access to your information. The reason is to perform the tasks assigned to them on our behalf. However, they are obligated not to disclose or use the information for any other purpose.

Subscription-Based Features

The STAELLA app offers subscription-based features that provide access to all non-consumable items for a limited period. By subscribing, users can enjoy all premium features and content without the need to purchase individual non-consumable items.

Once a subscription is active, purchasing individual non-consumable items is no longer necessary or available, as the subscription grants full access to these items for the duration of the subscription period.

Payment for subscriptions will be processed through your Apple App Store account. Subscription details, including duration and price, are displayed within the app before purchase.

Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple ID account settings after purchase.

Non-Consumable Items

The STAELLA app also offers non-consumable items for purchase through Apple's payment system. These items are available under the following conditions:

  • Users who have previously purchased at least one non-consumable item before the introduction of the subscription model retain full access to these items.
  • Such users can continue to purchase non-consumable items without being restricted by the subscription paywall.
  • New users or users without prior purchases of non-consumable items will need to subscribe to access premium content and services.

This policy ensures that early supporters of the STAELLA app retain their benefits and access rights, while new users can enjoy enhanced features through the subscription model. Payment details for these purchases are processed by Apple according to their privacy policy.

Security

We value your trust in providing us with your data, thus we strive to use commercially acceptable means of protecting it. But remember that "no method of transmission over the internet or method of electronic storage is 100% secure and reliable" and guarantees cannot be made.
