Privacy Policy
Effective date: April 12, 2026
Fever Muse is a private, adult-only AI companion platform. This Privacy Policy explains what information we collect, how we use it, who we share it with, and what rights you have. Privacy, memory transparency, and controlled data handling are built into the product — not treated as an afterthought.
This Privacy Policy applies to all users of the Fever Muse platform, including the website, web application, and any related services (collectively, the "Service"). By accessing or using the Service, you acknowledge that you have read, understood, and agree to the collection, use, and disclosure of your information as described in this policy. If you do not agree, you must not use the Service.
We collect information you provide directly, including account registration data (email address, authentication credentials), companion configuration and preferences, conversation content and scenario history, memory items you create or that are generated during use, wallet and transaction records, media generation prompts and job metadata, and any communications you send to us. We also collect information automatically, including device and browser identifiers, IP address, operating system, referring URLs, pages visited, session duration, feature usage and interaction events, coin spend and generation metrics, latency and error telemetry, and cookies and similar tracking technologies as described in our Cookie Policy.
We process your personal data on the following legal bases under applicable data protection law: (a) Contract performance — processing necessary to provide the Service you have requested, including account management, conversation delivery, memory persistence, billing, and media generation; (b) Legitimate interests — processing necessary for our legitimate business interests, including platform security, fraud prevention, abuse detection, service reliability monitoring, and product improvement, where those interests are not overridden by your data protection rights; (c) Legal obligation — processing necessary to comply with applicable laws, regulations, court orders, or governmental requests; (d) Consent — where you have given specific, informed consent for a particular processing activity, such as optional analytics or marketing communications. You may withdraw consent at any time without affecting the lawfulness of processing performed before withdrawal.
We use the information we collect to: provide, maintain, and improve the Service, including conversation coherence, memory recall, and companion personalization; process transactions, manage wallet balances, and enforce plan entitlements; enforce our Terms of Service, Safety Policy, and applicable law; detect, investigate, and prevent fraud, abuse, policy violations, and security incidents; monitor platform reliability, performance, and cost efficiency; generate aggregated, de-identified analytics for product development; communicate with you about your account, service changes, and (where you have opted in) promotional materials; and comply with legal obligations and respond to lawful requests.
Fever Muse is an adult-only platform. Conversation content, scenario interactions, and generated media may include adult or sexually explicit material. We treat all conversation content and generated media as sensitive data and apply heightened access controls and retention safeguards. This content is used solely to deliver and improve the Service and is never sold, shared for advertising purposes, or used to build advertising profiles.
We do not sell your personal data. We share information only in the following circumstances: (a) Service providers and processors — we use third-party infrastructure providers to operate the Service, currently including Supabase (database, authentication, file storage), Vercel (web hosting and edge runtime), QStash-compatible services (async job processing), AI model providers (conversation and generation inference), and payment processors (subscription and transaction handling). These providers process data on our behalf under contractual obligations that require them to protect your data and use it only as instructed. (b) AI model providers — conversation prompts and context windows are sent to third-party AI model providers to generate responses. We do not permit these providers to use your data for their own model training, though their retention and processing practices are governed by their own terms. (c) Legal requirements — we may disclose information if required by law, regulation, legal process, or governmental request, or if we believe disclosure is necessary to protect rights, safety, or property. (d) Business transfers — in the event of a merger, acquisition, or asset sale, your information may be transferred as part of that transaction, subject to the commitments in this policy.
We retain your personal data for as long as your account is active or as needed to provide the Service. Conversation content and memory items are retained for the duration of your account unless you delete them earlier. Transaction and billing records are retained as required by applicable tax and financial regulations (typically up to seven years). Telemetry and analytics data is retained in aggregated or de-identified form. Policy-event logs (safety violations, abuse flags) may be retained beyond account deletion as necessary for legal compliance, dispute resolution, and platform security. When you delete your account, we will delete or de-identify your personal data within 30 days, except where retention is required by law or for the legitimate purposes described above.
The Service is operated from the United States. If you access the Service from outside the United States, your information will be transferred to, stored in, and processed in the United States and potentially other jurisdictions where our service providers operate. These jurisdictions may have data protection laws that differ from those in your jurisdiction. By using the Service, you consent to the transfer of your information to the United States. Where required by applicable law, we rely on appropriate transfer mechanisms, including Standard Contractual Clauses approved by the European Commission, to safeguard transfers of personal data.
Depending on your jurisdiction, you may have the following rights regarding your personal data: the right to access the personal data we hold about you; the right to correct inaccurate or incomplete data; the right to delete your personal data (subject to legal retention requirements); the right to restrict or object to certain processing activities; the right to data portability (receiving your data in a structured, commonly used format); the right to withdraw consent where processing is based on consent; and the right to lodge a complaint with a supervisory authority. To exercise any of these rights, contact us using the information provided at the end of this policy. We will respond to verifiable requests within the timeframes required by applicable law (typically 30 days, extendable by an additional 60 days for complex requests).
If you are a California resident, you have additional rights under the California Consumer Privacy Act as amended by the California Privacy Rights Act. We do not sell personal information as defined by the CCPA/CPRA. We do not use or disclose sensitive personal information for purposes other than those permitted under the CCPA/CPRA. You have the right to know what personal information we collect, the right to delete your personal information, the right to correct inaccurate information, and the right to not be discriminated against for exercising your privacy rights. To submit a request, contact us using the information at the end of this policy.
The Service is not directed to, and we do not knowingly collect personal information from, anyone under the age of 18. The Service requires age verification before access to adult content. If we learn that we have collected personal information from a person under 18, we will delete that information promptly. If you believe a minor has provided us with personal information, please contact us immediately.
We implement commercially reasonable technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. These measures include encryption in transit (TLS), access controls, audit logging, and regular security reviews. However, no method of transmission over the internet or method of electronic storage is completely secure, and we cannot guarantee absolute security.
We may update this Privacy Policy from time to time to reflect changes in our practices, the Service, or applicable law. If we make material changes, we will notify you by posting the updated policy on the Service with a revised effective date and, where required by law, by providing additional notice (such as an in-app notification or email). Your continued use of the Service after the effective date of any changes constitutes your acceptance of the updated policy.
