Compose, produce, and publish — in one studio.
A professional notation editor, a multitrack DAW, and a mixing console — fused with a private, encrypted network to share what you make.

Multitrack DAW
Arrange audio and MIDI across up to 64 tracks with a real mixer.
Release & read
Ship music, albums, sheet music, books, and video to a built-in library.
Private network

Compose & notate
Write it the way you hear it.
A complete notation editor — from a lead sheet to a full grand-staff arrangement — with the marks performers actually read.
- Full engraving — multiple staves, grand staff, guitar tab, and drum notation.
- Marks & expression — articulations, dynamics, ornaments, slurs, ties, and barlines.
- Lyrics, chords & a tempo map — words under the staff, chord symbols above, and tempo changes across the piece.

- Compose on your phone — a notation-first touch editor that round-trips to the desktop studio.
Produce & mix
A full DAW and a real console.
Arrange, edit, and mix a whole session — audio and instruments together — then bounce it to a finished track.

- Piano roll & instruments — sampled acoustic piano plus synth and drum voices, with gapless looping.
- Automation, humanize & swing — draw volume curves and expression, modulation, sustain, and pitch-bend lanes.
- Mixing console — 3-band EQ, pan, reverb, faders with VU / peak meters, mute / solo, and a master DIM.

Get ideas down fast.
Play parts in from the keys you already have, and capture takes in real time.
- Musical Typing — play notes straight from your computer keyboard.

Privacy Policy
Effective Date: August 11, 2026
Last Updated: August 11, 2026
1. Introduction and Scope
This Privacy Policy describes how DMTA Studios, LLC ("DMTA Studios," "we," "us," or "our"), located in Bowling Green, Kentucky, USA, collects, uses, and protects your personal information. This policy applies to your use of the HarmoniSensei™ application across all platforms (Android, macOS, Windows, Web) and our associated backend services (collectively, the "Service").
2. Our Zero-Knowledge Architecture (What We Cannot See)
Privacy is built into the core of HarmoniSensei™. We utilize post-quantum end-to-end encryption (E2EE) and hardware-backed local encryption to protect your communications.
- Zero-Knowledge Messaging: Direct messages, group text channels, and their attached media are end-to-end encrypted. We act strictly as a zero-knowledge relay. We cannot read your messages, decrypt your private media, or listen to your voice and video calls.
- Call Routing: Voice and video calls are established peer-to-peer. We only relay encrypted media through our servers if a direct connection cannot be established.
- Local Biometrics: HarmoniSensei™ uses your device’s biometric authentication (fingerprint or facial recognition) to unlock your encrypted local chat storage. We never collect, store, or transmit your biometric data. This process happens entirely on your local device's secure hardware.
3. Information We Collect
While we cannot access your E2EE communications, we do collect specific data necessary to operate the platform, route messages, and manage accounts.
- Account & Identity Data: Your email address, phone number, display name, username (handle), and password (which is strictly stored using Argon2id cryptographic hashing; we never hold passwords in plaintext).
- Profile Data: Optional information you choose to provide, such as an avatar, banner image, bio, birthday, gender, pronouns, and website URLs.
- User-Generated Content (Public): Posts, articles, books, podcasts, videos, and music you publish to public or subscriber-only tiers, alongside your community interactions (comments, reactions).
- Commerce Data: Purchase and subscription records. Payment processing is handled entirely by our payment provider (Stripe). We do not collect or store your credit card or bank account numbers.
- Device & Technical Data: App version, operating system, push notification tokens, and per-account device identifiers required strictly for routing your encrypted messages to the correct device.
- AI Generation Data: Prompts you submit to the "AI Canvas" feature and the resulting generated text, image, audio, or video outputs.
4. What We Do NOT Do
To provide further clarity on our privacy commitments:
- We do not sell your personal data.
- We do not use third-party advertising networks.
- We do not embed third-party tracking SDKs to monitor your behavior across other apps or websites.
5. How We Use Your Information
We process your data strictly to:
- Create and secure your account (including Two-Factor Authentication).
- Route E2EE messages and establish WebRTC call signaling.
- Distribute public and subscriber-only media via IPFS.
- Facilitate creator monetization, virtual gifts, and subscriptions.
- Generate content via the AI Canvas upon your direct request.
- Comply with legal obligations and enforce our Terms of Service.
6. Sub-Processors and Third-Party Sharing
We share specific data with trusted third-party providers solely to deliver platform features. We ensure these providers are bound by strict data processing agreements.
| Provider | Purpose | Data Shared |
|---|---|---|
| Stripe | Payments & Creator Subscriptions | Purchase metadata; identity data for Connect onboarding |
| Pinata (IPFS) | Decentralized Media Storage | Uploaded media (encrypted at rest via AES-256-GCM) |
| Cloudflare | TURN Relay for Calls | Real-time encrypted media (only when direct peer-to-peer fails) |
| Google Cloud / Firebase | Hosting & Notifications | Server-side routing data, device push tokens |
| Google, MiniMax, ByteDance, Vidu, Alibaba | AI Canvas Generation | User prompts and generated media outputs |
| GitHub | App Updates | None (used strictly for downloading signed app updates) |
7. International Data Transfers & AI Canvas
Because DMTA Studios is based in the United States, your data is processed in the US. However, to provide our AI Canvas features, we partner with AI model providers located globally, including the People's Republic of China (e.g., MiniMax, ByteDance, Vidu, Alibaba). When you use the AI Canvas, you acknowledge that your prompt data will be transmitted to these international sub-processors. For users in the European Economic Area (EEA) and the UK, we safeguard these transfers utilizing Standard Contractual Clauses (SCCs) approved by the European Commission, ensuring your prompts are used exclusively to fulfill your request and not to independently train third-party foundation models.
8. Data Retention, Blockchain Immutability, and Deletion
You may delete your account at any time through the app settings. Upon deletion, we remove your account credentials, profile data, and plaintext routing logs from our central database. Exceptions to Deletion:
- E2EE Content: Because we do not hold the decryption keys, we cannot recover or delete encrypted chat history stored locally on your device or on the devices of your recipients.
- Blockchain Data: HarmoniSensei™ integrates with SempreChain™. Any transactions, token delegations, or DAO proposals you voluntarily commit to the public blockchain are immutable and cannot be deleted or altered by DMTA Studios.
- Financial Records: We retain transactional data related to creator monetization as required by US tax and accounting laws.
9. Your Privacy Rights (KCDPA & GDPR)
Depending on your jurisdiction—including residents of Kentucky (under the KCDPA) and the European Union (under the GDPR)—you maintain specific rights regarding your data:
- Right to Access & Portability: Request a copy of the personal data we hold about you. (Note: We cannot export the plaintext content of E2EE messages).
- Right to Deletion: Request the erasure of your personal data, subject to the blockchain and financial exceptions noted above.
- Right to Correction: Update or correct inaccurate profile data.
- Right to Opt-Out of Sensitive Data Processing: We require your explicit opt-in consent to process sensitive data, such as sharing your precise location in a chat (which operates peer-to-peer).
- Right to Appeal: If we decline a data request, you have the right to appeal our decision.
To exercise these rights, please contact us at david.williams@dmtastudios.com or via the privacy settings within the HarmoniSensei™ app.
10. Age Requirements and Children's Privacy
HarmoniSensei™ is not directed at children. You must be at least 18 years old to create an account. We do not knowingly collect personal data from children under 18. Furthermore, users must be at least 18 years old to utilize Creator Monetization features, purchase virtual gifts, or participate in the SempreChain™ DAO. If we discover we have collected data from a user under 18 without verifiable parental consent, we will delete the account immediately.
