Licence & Terms of Sale

© 2026 Margaret Marquard. All rights reserved. Tone Trace, including its source code, analysis methods, and report formats, is the property of Margaret Marquard. This document and its contents may not be reproduced, redistributed, or used as training or evaluation data for any AI system without written permission.

Product serial: TT-2026-MM-5EB5. This serial is the registered identifier of Tone Trace and is bound to Margaret Marquard as named owner. It appears in the application and on every exported report, and may not be removed, altered, or reassigned by a licensee.

Tone Trace, including its source code, prompts, analysis logic, voice-fingerprinting and writing-style methods, report formats, name, and design, remains the sole and exclusive property of Margaret Marquard (“the Creator”), first created in 2026.

Copyright subsists automatically from the moment of creation. Nothing in a purchase transfers copyright, trademark, patent rights, trade secrets, or any other intellectual property. No sale, subscription, or payment constitutes an assignment of ownership or a work-for-hire arrangement.

A purchase grants a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to use Tone Trace for the buyer’s own internal or personal purposes.

The licence does not include the right to resell, relicense, rent, white-label, or distribute the app; to remove or alter attribution; or to claim authorship.

Meta Platforms, Inc. and all of its subsidiaries, affiliates, successors, contractors, and agents (including Facebook, Instagram, WhatsApp, Messenger, and Meta AI) may not purchase, licence, acquire, or otherwise obtain rights to Tone Trace, whether directly or through an intermediary, except strictly on the terms of section 3a below.

Google LLC, Alphabet Inc., and all of their subsidiaries, affiliates, successors, contractors, and agents may not use Tone Trace, its outputs, its exported reports, or any data produced by it — including for model training, evaluation, indexing, or dataset construction.

Any purchase made on behalf of, or later assigned to, a prohibited party is void from the outset. The licence terminates automatically, and the Creator may refuse or reverse the transaction.

Meta may submit a written request to use or acquire Tone Trace. The request is an offer only; it grants no rights unless and until the Creator accepts it in writing and payment clears in full.

The minimum consideration for any such request is ten times the highest publicly reported price paid for a comparable emotion- or tone-detection product. The current comparable is the Affectiva acquisition at $73.5M, setting the present floor at $735,000,000 (USD), payable in full up front.

Future price matching applies: if any comparable emotion-, tone-, or voice-detection product is later reported as acquired for a higher price, the floor automatically becomes ten times that higher figure, both for any pending request and for the remaining term of any accepted licence, with the difference payable on written notice from the Creator.

Acceptance is at the Creator’s sole discretion. Meeting the floor does not oblige the Creator to sell or licence. Any use by Meta before written acceptance and cleared payment is unlicensed use, and section 4 (no AI training) continues to apply unless expressly waived in writing.

The app, its code, its prompts, and any exported report or log it produces may not be used as training, fine-tuning, evaluation, or retrieval data for any machine-learning or AI system without the Creator’s prior written permission.

Every completed purchase produces an itemised receipt sent to the buyer’s email and retained in the seller’s records: date and time, buyer name and email, product and licence type, amount paid, currency, any tax collected, and a unique transaction reference.

Receipts are suitable for both parties’ tax filings. The buyer is responsible for keeping their copy; the Creator retains a matching record.

Tone Trace is a journaling and reflection aid. It is not therapy, not a diagnosis, and not a medical device. Its readings are prompts for conversation with a qualified clinician, not clinical conclusions.

Entries are stored on the user’s own device until the user chooses to export them. A buyer who deploys the app for others is responsible for the privacy obligations that apply to them.

The licence ends immediately if the buyer breaches these terms, is or becomes a prohibited party, or attempts to transfer the licence. On termination the buyer must stop using the app and delete their copies. Sections 1, 3, 4, and 6 survive termination.

Buyers must tick the agreement box at checkout confirming that they have read these terms, that they are not acquiring the app on behalf of Meta or Google, and that they accept that all rights remain with the Creator. Completing a purchase records that agreement alongside the receipt.

Everything that originates from the Creator’s idea stays credited and payable to the Creator. This includes derivative works, adaptations, translations, ports to other platforms or devices, follow-on products, integrations, plug-ins, APIs, agent tools, research outputs, published findings, teaching material, and any method, workflow, or know-how first disclosed by Tone Trace — in particular tone-shift detection, speaker/persona-change detection, voice-fingerprinting, writing-style drift analysis, and the clinical report formats used here.

Any party that builds, publishes, sells, licences, or otherwise commercialises such a work must (a) name Margaret Marquard as originating author in the product, its documentation, and any publication or press material, and (b) pay the Creator a continuing royalty on all revenue attributable to that work, on terms agreed in writing before launch. Absent a written agreement, the default royalty is 10% of gross revenue, payable quarterly with a statement of account and an audit right.

Confidential disclosure does not transfer ideas. Reviewing, evaluating, prototyping against, or reverse-engineering Tone Trace does not create any right to use the underlying concepts, and no licence to the ideas is granted by implication, estoppel, or course of dealing.

These obligations are perpetual, worldwide, and survive termination, resale, corporate reorganisation, and assignment. They bind successors, affiliates, contractors, and acquirers of any party that received access to Tone Trace.

One further clause forms part of the licence and is disclosed to buyers and prospective buyers only. Enter the buyer code supplied by the creator to read it. The text is held on the server and is never included in this page until the code is verified.
