Privacy Policy
Last Updated: October 29, 2026
1. Introduction
Neumosys LLC ("Neumosys," "we," "us," or "our") values your privacy and is committed to protecting your personal information. This Privacy Policy explains how we collect, use, share, and safeguard your information when you use Neume (the "Service"), including the Neume apps, our websites (including neume.io and app.neume.io), our API and MCP servers, and Neume inside connected AI assistants. By using the Service, you consent to the practices described in this policy. If you do not agree, please refrain from using the Service.
2. Information We Collect
We collect information to provide and improve the Service, ensure security, and meet legal obligations. The information we collect includes:
2.1 Information You Provide
- Account Information: Your name, email address, and any other details you provide when you create an account through our authentication provider (Clerk), including when you sign in with Apple or Google. Accounts created by an AI agent through our agent sign-up endpoint have no email address; they may have a name the agent gives. API keys are stored only in a form that can't be turned back into the key.
- Payment Information: Processed by third-party services (Stripe, Apple App Store, Google Play Store, RevenueCat). When an AI agent pays through machine payments, Stripe processes the payment and we receive confirmation of it. We do not store your payment card details.
- Content You Create: Prompts, descriptions, lyrics and preferences you submit, your messages with Neume's song assistant, and the songs, music videos, images, characters, stems and sheet music you make, stored in your library.
- Uploaded Material: Audio, recordings (such as a hum or a voice memo), photos and video clips you upload to use with the Service.
- Voice Recordings: Recordings of your own voice that you provide to create a singing voice.
- Profile and Social Content: Your handle, name, profile photo and bio, and the posts, comments, stories, likes, follows, tags, dedications, reports and blocks you make.
- Support and Feedback: Information you provide when contacting support or giving feedback.
2.2 Information We Collect Automatically
- Usage Data: Pages and screens visited, actions taken, features used, and interactions with content, to improve the Service.
- Device Information: Device type, operating system, app version, browser type, IP address, and a device identifier used if you use the app before creating an account.
- Notification Tokens: If you allow notifications, a token from Apple or Google that lets us send them to your device.
- Diagnostics: Error and crash reports from the apps, such as the error message, the screen it happened on and the app and system versions.
- Cookies, Pixels and Similar Technologies: Used to keep you signed in, understand how the Service is used, and measure our advertising (see section 5).
2.3 Information from Third Parties
- Authentication and Payment Providers: Information from Clerk, Apple, Google, Stripe and RevenueCat that is needed to sign you in and deliver what you bought.
- Connected AI Assistants and Agents: When you use Neume through an AI assistant (such as ChatGPT or Claude) or an agent, we receive what it sends to our tools, such as your song requests, lyrics and files you attach. The assistant's provider handles your conversation under its own privacy policy.
- Analytics and Advertising Providers: Information about how you found and use the Service (see section 5).
3. How AI Features Use Your Content
- Songs, videos and images: Your prompts, lyrics, uploaded material and characters are processed by AI model providers to make what you ask for.
- Song assistant: Your messages are processed by AI model providers to write replies, lyrics and suggestions. The assistant may save short notes about your preferences (such as styles you like) to make better suggestions later. You can see and delete these notes in the app.
- Audio you upload: Audio is transcribed to find its words and parts, so you can change them.
- Photos you upload: An AI model looks at each photo to tell whether it shows a person and to describe it, so the right options and permission questions appear. When you make a video of a person, the model compares the photo with the portraits of characters already saved in your account, to reuse a character for the same person instead of making a new one. This comparison is limited to your own characters. We do not create stored face templates, and we do not use photos to identify who a person is.
- Characters: A character drawn from a photo is saved to your account as a portrait and reference images, so it can be used again. You can delete it at any time.
- Singing voices: Recordings of your voice are processed by our voice provider to create the singing voice. A voice you publish can be chosen by other users to make songs.
4. How We Use Your Information
We use collected information to:
- Provide, maintain, and improve the Service.
- Process payments and manage subscriptions.
- Make songs, music videos, images, characters and voices from your requests.
- Run social features, such as profiles, posts, comments, follows and notifications.
- Personalize suggestions in the song assistant.
- Train and improve our AI models.
- Measure and improve our advertising.
- Communicate with you about updates, support, and promotional offers.

5. Cookies, Analytics and Advertising
- Analytics: We use PostHog, Google Analytics for Firebase and Microsoft Clarity to understand how the Service is used. Clarity can record how you move through screens and pages (session recordings), so we can find and fix problems.
- Advertising measurement: Our websites use tags from advertising partners, including Google Ads and OpenAI, to measure whether our ads lead to sign-ups and purchases.
- Your choices: You can manage cookies in your browser settings. On iOS, the app asks your permission before tracking you across other companies' apps and websites, and you can change your choice in your device settings.
6. Information Sharing
We share your information only as necessary and in the following circumstances:
- Other Users and the Public: Your profile and the content you make public, such as posts, comments, stories, likes, follows and published voices, can be seen by other users. Links to public or unlisted songs and videos can be opened by anyone who has them, including outside the Service. Copies of videos made for sharing may include your handle.
- Service Providers: Third-party companies that assist with operations, including:
- Authentication services (Clerk)
- Payment processors (Stripe, Apple, Google, RevenueCat)
- Analytics providers (PostHog, Google, Microsoft)
- Advertising partners (Google, OpenAI), for measuring ads

- With Your Consent: We may share information for purposes you approve of.
We do not sell your personal information to third parties.
7. Data Security
We implement industry-standard security measures to protect your information from unauthorized access, loss, or misuse. While we strive for complete security, no system is 100% secure. You are responsible for maintaining the confidentiality of your account credentials and API keys.

9. Data Retention
We retain your information as long as your account is active or as necessary for legal, security, and operational purposes. Upon account deletion, data is removed unless retention is required by applicable laws.
- Stories disappear after 24 hours.
- Deleted content: When you delete a post or other content, it is removed from the Service, but copies or links others saved or shared, and content others made from it while that was allowed, may remain.
- Email Address Retention: We indefinitely retain email addresses associated with deleted accounts to prevent credit system abuse and enforce platform restrictions. This data is used solely for fraud prevention and is not used for marketing purposes.

Your information may be processed in countries where data protection laws differ from your jurisdiction. By using the Service, you consent to these transfers. We ensure safeguards are in place to protect your information.

The Service is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If we discover such information has been collected, it will be deleted promptly. Photos of anyone under 18 may not be used to make videos or characters.
12. Changes to This Privacy Policy
We may update this Privacy Policy periodically. Significant changes will be communicated via the Service or your registered email. Continued use of the Service after changes take effect indicates your acceptance of the updated policy.
