(Last updated: October 12, 2026)
These Terms of Use (hereinafter referred to as "these Terms") set forth the conditions for using the services (hereinafter referred to as "the Service") provided by the "Cloud Identifier" App Development Team (hereinafter referred to as "the Team") through this application (hereinafter referred to as "the App"). These Terms constitute the end user license agreement (EULA) for the App. All users of the Service (hereinafter referred to as "Users") are expected to use the Service in accordance with these Terms.
The primary purpose of the Service is to allow Users to identify cloud types from photos taken with a camera or selected from the gallery and to check cloud names and characteristics.
These Terms shall apply to all relationships between Users and the Team regarding the use of the Service.
In addition to these Terms, the Team may establish various rules and regulations (hereinafter referred to as "Individual Provisions") regarding the use of the Service. Regardless of their designation, these Individual Provisions shall constitute a part of these Terms.
In the event that the provisions of these Terms conflict with the Individual Provisions, the Individual Provisions shall take precedence unless otherwise specified in the Individual Provisions.
Users agree to these Terms by using the Service. Users do not need to register an email address, a password, or a name to use the Service.
On first launch, the App automatically creates an anonymous account with a randomly generated identifier so that each User's identification history can be associated with the User's device. Users shall not attempt to use, access, or interfere with another User's anonymous account or data.
The identification features of the Service require a paid auto-renewing subscription. The available plans, prices, and any free trial are shown in the App before purchase. A free trial, where offered, is available only to eligible Users. If a free trial is offered, any unused portion of the free trial period will be forfeited when the User purchases a subscription, where applicable.
Payments are processed by Apple through the User's Apple ID account, or by Google through the User's Google Play account, depending on the platform used. Payment is charged at confirmation of purchase or, for a plan with a free trial, at the end of the free trial. The subscription renews automatically for the same period and price unless it is canceled. On iOS, a subscription must be canceled at least 24 hours before the end of the current period, including a free trial period, to avoid being charged for the next period. On Android, a subscription can be canceled at any time, and access continues until the end of the current billing period. Users can manage and cancel subscriptions in the subscription settings of their Apple ID or Google Play account. Deleting the App does not cancel a subscription.
Refunds are handled by Apple or Google in accordance with their respective policies. The Team does not receive or store Users' credit card numbers or other payment details.
To keep the Service stable and to prevent misuse, the Team may set a limit on the number of identifications each account can make per day, and may change that limit. When the limit is reached, further identifications become available again on the following day.
Users shall not engage in any of the following activities when using the Service:
The Team may suspend or interrupt all or part of the Service without prior notice to Users if it determines that any of the following reasons exist:
The Team shall not be liable for any disadvantage or damage suffered by Users or third parties due to the suspension or interruption of the Service, except in cases of intentional or gross negligence on the part of the Team.
Users may only use the Service with images for which they hold the necessary rights, or for which they have obtained the necessary permission from the rights holders.
The rights to images uploaded by Users remain with the respective Users or other rights holders. Users grant the Team permission to process uploaded images, and to have them processed by the external services described in the Privacy Policy, to the extent necessary to provide the Service, and to store reduced-size thumbnails and identification results in the User's history. The Team does not use Users' images for advertising or promotion.
Except as set forth above, all copyrights and other intellectual property rights related to the Service and all information associated with the Service belong to the Team or the rights holders who have licensed their use to the Team. Users shall not reproduce, transfer, lend, translate, modify, reprint, publicly transmit (including making transmittable), distribute, publish, or commercially use such content without authorization.
The Team may, without prior notice, restrict all or part of the use of the Service by a User, or delete data associated with the User's account, if it determines that the User falls under any of the following:
The Team shall not be liable for any damage incurred by Users as a result of actions taken by the Team under this article, except in cases of intentional or gross negligence on the part of the Team.
Users may stop using the Service at any time. To stop being charged, Users must cancel their subscription in the subscription settings of their Apple ID or Google Play account; deleting the App alone does not cancel a subscription.
Users can delete individual saved identifications, together with their stored thumbnails, from the History screen of the App. Deleting the App does not delete data stored on the Team's servers. Users who wish to have all data associated with their anonymous account deleted may contact the Team at the address below.
The identification results provided by the Service are generated by artificial intelligence (AI) and are estimates only. The Team does not guarantee the accuracy, completeness, or reliability of the identification results, including the cloud genus and species, the confidence scores, the ranked alternative candidates, or the accompanying explanations.
In particular, the Service may identify a cloud incorrectly. Cloud classification depends on features such as altitude, form, and texture that can be ambiguous in a single photograph, and different genera can appear similar under certain lighting and viewing conditions. The Service presents ranked alternative candidates with confidence scores precisely because a single identification cannot be treated as definitive.
Any information about the weather typically associated with an identified cloud is general educational background and is not a weather forecast. The Service does not predict weather, and Users must never rely on it for decisions where weather conditions matter, including but not limited to aviation, maritime activity, mountaineering, agriculture, construction, and the safety of persons or property. For such purposes, Users should always consult official meteorological services and qualified professionals.
The Team shall not be liable for any loss, damage, or other harm arising from actions taken based on the identification results or accompanying information provided by the Service, except in cases of intentional or gross negligence on the part of the Team. Users use the identification results at their own risk and responsibility.
The Team does not warrant, either expressly or implicitly, that the Service is free from defects in fact or in law (including defects related to safety, reliability, accuracy, completeness, effectiveness, fitness for a particular purpose, security, errors, bugs, and infringement of rights).
The Team shall not be liable for any damage incurred by Users arising from the Service, except in cases of intentional or gross negligence on the part of the Team. However, this disclaimer shall not apply if the contract between the Team and the User regarding the Service (including these Terms) constitutes a consumer contract as defined by the Consumer Contract Act of Japan.
Even in the cases set forth in the proviso of the preceding paragraph, the Team shall not be liable for any damage arising from special circumstances (including cases where the Team or the User foresaw or could have foreseen the occurrence of damage) among damages incurred by Users due to the Team's negligence (excluding gross negligence) in breach of contract or tort. Furthermore, compensation for damages incurred by Users due to the Team's negligence (excluding gross negligence) in breach of contract or tort shall be limited to the amount of subscription fees paid by the User for the Service in the month in which the damage occurred.
Nothing in these Terms limits any rights that Users may have under the mandatory consumer protection laws of their country of residence.
The Team may change, add to, or discontinue the content of the Service with prior notice to Users, and Users shall consent to this.
The Team may modify these Terms without obtaining individual consent from Users in the following cases:
When modifying these Terms pursuant to the preceding paragraph, the Team shall notify Users in advance, by posting on this page or in the App, of the intent to modify these Terms, the content of the modified Terms, and the effective date of the modifications.
The Team shall handle information obtained through the use of the Service appropriately in accordance with the Team's Privacy Policy.
Notices from the Team to Users shall be made by posting on this page or in the App. Inquiries from Users to the Team shall be made by email to the address below.
Users may not assign their contractual status or any rights or obligations under these Terms to a third party, or offer them as collateral, without prior written consent from the Team.
These Terms shall be governed by and construed in accordance with the laws of Japan, without prejudice to the mandatory consumer protection laws of the User's country of residence.
In the event of any dispute arising in connection with the Service, the court having jurisdiction over the location of the Team shall have exclusive agreed jurisdiction as the court of first instance, except where the mandatory laws of the User's country of residence provide otherwise.
