Privacy Policy

Sho Fujimoto (hereinafter referred to as "Developer") establishes this privacy policy (hereinafter referred to as "this Policy") regarding the handling of user information in the mobile application "Romance" (hereinafter referred to as "this Application") provided by the Developer. This Application offers an ad-supported free tier and an optional ad-free Premium subscription. This Policy aims to comply with the Act on the Protection of Personal Information (hereinafter referred to as the "APPI") and to appropriately protect users' privacy information.

Article 1 (Information Handled)

This Application does not require an account. It stores your nickname, profile generated from play, game progress and statistics, story choices, conversation and story history, minigame records, and preferences on your device. A nickname may identify you if you choose to use your real name.

When you use online features, information needed to provide those features is transmitted as described below. Service providers may also process IP addresses, device and OS information, request times, diagnostics, advertising identifiers subject to consent and device permissions, and purchase identifiers. The Developer receives your email address and the information you send when you contact support.

Article 2 (Collection and Transmission)

• AI generation: With your permission in version 2.0, the app sends the nickname, message, relevant conversation history, stored profile, story choices, and game statistics needed for generation through the Developer's backend to the AI providers in Article 4.
• Reports: When you choose to report content, the reported content and accompanying report information are sent to the Developer and stored using Cloudflare R2 for investigation and response. Do not include unnecessary personal or sensitive information.
• Subscriptions: The app, RevenueCat, and Apple or Google process purchase and entitlement information to provide, restore, and manage Premium.
• Advertising and operation: Advertising SDKs and infrastructure providers process device, network, consent, usage, and diagnostic information as described in Article 5.

The app does not request access to your camera, photo library, or precise device location. Advertising and infrastructure providers may infer an approximate location from your IP address.

Article 3 (Purposes of Use)

Information is used to run the game and generate responses, save local progress, provide and restore subscriptions, deliver and measure advertisements where applicable, honor privacy choices, investigate reported content, answer support requests, diagnose errors, improve service reliability, prevent misuse, and comply with applicable legal obligations. The app does not send your chat text or profile to advertising SDKs for advertising targeting. While Premium is active, the app does not request or display advertisements.

Article 4 (Generative AI)

Version 2.0 uses DeepSeek and Alibaba Cloud Model Studio (Qwen) to generate stories and dialogue. If one provider is unavailable or generation fails, the request may be sent to the other provider. The data listed in Article 2 is transmitted through our backend only after you allow AI sharing. You can decline and continue using minigames. You can change or withdraw AI permission in the app's Privacy Settings; withdrawal stops subsequent AI requests and does not delete information already processed by a provider.

For users who have not updated, the legacy version 1.x service uses DeepSeek and may use OpenAI for fallback generation and safety moderation. The version 2.0 consent screen and provider selection described above apply to version 2.0.

• DeepSeek Privacy Policy
• Alibaba Cloud Privacy Policy
• Alibaba Cloud Model Studio privacy information
• OpenAI Privacy Policy (legacy service)

Normal conversations and stories are saved as app history on your device, rather than as a conversation-history database on the Developer's server. This does not mean that no data is processed or retained by servers: requests pass through Cloudflare and AI providers; operational and error logs may be retained; content you explicitly report is stored for review. Providers' processing, retention, and use of inputs and outputs are governed by their applicable policies and service terms. We do not promise that every provider deletes data immediately or excludes every request from training. Data may be processed outside your country, including in China by DeepSeek and in the regions used by Alibaba Cloud and other providers. Avoid entering confidential information or personal information about others.

Article 5 (Third-Party Services)

• Google AdMob / Google Play Services: Advertisement delivery, measurement, consent management, and platform functions. Depending on privacy choices, providers may process advertising identifiers, IP address, device information, ad interactions, and diagnostics. Google Privacy Policy, AdMob privacy information.
• RevenueCat: Subscription validation, purchase restoration, and Premium entitlement management. It processes an anonymous app user ID, purchase or transaction identifiers, product, entitlement and subscription status, and device or app information. An anonymous ID is a pseudonymous identifier, not a guarantee that purchase data cannot be linked. The app does not send chat history to RevenueCat. RevenueCat Privacy Policy.
• Apple App Store / Google Play: Payment and subscription processing under the store's terms. The Developer does not receive your full payment-card details. Apple Privacy Policy, Google Privacy Policy.
• Cloudflare: Backend request processing, service operation and diagnostics, and storage of user-submitted reports in R2. Cloudflare Privacy Policy.
• Expo: App delivery, updates, and operational diagnostics where enabled, including app version, device and usage information. Expo Privacy Policy.

Advertising Privacy Choices

Google AdMob and its advertising partners may process advertising identifiers, IP addresses, device information, and ad interactions for ad delivery and measurement. The applicable partners and purposes are shown in Google's UMP consent form where available. See the AdMob ad technology providers and IAB TCF vendor list for further information; the applicable list can change.

In version 2.0, open Privacy Settings → Advertising privacy settings to reopen Google's privacy options form where it is available for your region and configuration. You may change or withdraw the choices offered there. If no form is available, the app explains this. After a change, loaded advertisements are discarded and subsequent ad requests follow the updated consent state. Declining personalized advertising does not necessarily remove all ads. Active Premium removes advertisements.

On iOS, App Tracking Transparency permission is separate from Google's consent form. You can change tracking permission in your device settings. Android advertising identifier controls are also available in device settings. You can use the app without granting tracking permission.

Where applicable, users in the EEA, UK, and Switzerland may exercise rights of access, rectification, erasure, restriction, portability, objection, and withdrawal of consent, and may complain to the relevant supervisory authority. Contact the Developer using Article 15. Withdrawal does not affect the lawfulness of processing before withdrawal.

Article 6 (Provision of Privacy Information to Third Parties)

Except in the cases listed below and as stipulated in Article 4 and Article 5, the Developer will not provide Personal Information to a third party without obtaining the prior consent of the user.

1. When required by law.
2. When it is necessary for the protection of a person's life, body, or property, and it is difficult to obtain the consent of the individual.
3. When it is particularly necessary for improving public health or promoting the sound upbringing of children, and it is difficult to obtain the consent of the individual.
4. When it is necessary to cooperate with a state organ, a local government, or an individual entrusted by either of the foregoing in executing affairs prescribed by laws and regulations, and obtaining the consent of the individual is likely to impede the execution of the affairs concerned (including responding to fraud investigations and government requests).
5. When entrusting the handling of Personal Information in whole or in part within the scope necessary for the achievement of the purpose of use (outsourced parties are limited to trusted service providers who perform work on behalf of the Developer, do not independently use the disclosed information, and have agreed to adhere to the rules set forth in this privacy statement. Appropriate supervision will be exercised over outsourced parties).
6. When Personal Information is provided as a result of the succession of business in a merger or otherwise.
7. When the Developer, in good faith, deems disclosure necessary to protect the Developer's rights, protect the user's safety or the safety of others.

Article 7 (Disclosure, Correction, Suspension of Use, etc., of Personal Information)

1. When a user requests notification of the purpose of use, disclosure, correction, addition, or deletion of their own Personal Information, or suspension of use or erasure, or suspension of provision to third parties (hereinafter collectively referred to as "Disclosure, etc.") based on the provisions of the APPI, the Developer will respond without delay after confirming the identity of the individual. (If the said Personal Information does not exist, the user will be notified to that effect.) However, this does not apply if the Developer is not obligated to perform Disclosure, etc. under the APPI or other laws and regulations.
2. A fee of 1,000 yen per request may be charged for notification of the purpose of use and disclosure of Personal Information.
3. For specific procedures regarding requests for Disclosure, etc., please contact the inquiry desk in Article 15.

Article 8 (Correction and Deletion of Personal Information)

1. If a user's own Personal Information held by the Developer is incorrect, the user may request the Developer to correct or delete the Personal Information according to the procedures established by the Developer.
2. If the Developer determines that it is necessary to respond to the request from the user as described in the preceding paragraph, the Developer will correct or delete the said Personal Information without delay and notify the user of this.

Article 9 (Your Choices)

You can stop future AI transmission by withdrawing AI permission in version 2.0 Privacy Settings, and change advertising choices as described in Article 5. Uninstalling stops new collection by the installed app and normally removes its local data. Device or cloud backups and data already held by providers may remain under their own settings and retention policies. Uninstalling does not cancel a subscription; manage it through Apple or Google. Contact the Developer to request deletion of reports or support information that we hold.

Article 10 (Data Retention)

Local game and conversation data remain on your device until removed by the app's data controls, operating system, or uninstallation, subject to device backups. The Developer retains submitted reports, support correspondence, and operational records only for the reasonable period needed to investigate and respond, operate and protect the service, resolve disputes, and meet legal obligations. AI providers, RevenueCat, stores, and other providers apply their own applicable retention policies; we do not specify a universal deletion period. For requests concerning information held by the Developer, contact Article 15 and include enough information to locate the record without sending unnecessary sensitive data.

Article 11 (Children's Privacy)

The Developer does not knowingly collect Personal Information from children under the age of 13 or market to children under the age of 13. This Application is not intended for anyone under the age of 13. In the event that the Developer discovers that a child under 13 has provided Personal Information, the Developer will immediately delete this from their servers. If you are a parent or guardian and you are aware that your child has provided us with Personal Information, please contact the inquiry desk in Article 15 so that the necessary actions can be taken.

Article 12 (Security of Privacy Information)

The Developer is concerned about safeguarding the confidentiality of your information and takes necessary and appropriate measures, including physical, electronic, and procedural safeguards, to prevent leakage, loss, or damage of Privacy Information handled and to otherwise securely manage it. The Developer strives to implement technical and physical security measures. Specifically, this includes communication encryption, implementation of access control, and limiting retention to the purposes described in Articles 4 and 10. For specific details of security management measures, please contact the inquiry desk in Article 15.

Article 13 (Changes to Privacy Policy)

1. The Developer may change the contents of this Policy from time to time as necessary.
2. The revised Privacy Policy will be announced by updating it within this Application or on this page (the page where the privacy policy is posted). Users are advised to consult this Policy regularly for any changes. If the changes require user consent under applicable laws, the Developer will obtain user consent in a manner prescribed by the Developer. Continued use of this Application after changes (excluding changes requiring consent under applicable laws) will be deemed approval of all changes.

Article 14 (Governing Law)

The interpretation of this Policy shall be governed by the laws of Japan.
