Our Charter

Purple Mainspring is not yet incorporated. These are the commitments we will write into our certificate of incorporation when we organize as a Delaware Public Benefit Corporation — and once filed, they cannot be quietly removed: converting away from that structure requires a supermajority shareholder vote, a step that would be public and require our direct participation. We publish them before filing so anyone can hold us to them.

AI Accountability

Our AI recommends. It doesn't decide.

Every product we build that uses AI is designed around one principle: you are always in control. AI surfaces options, flags risks, and makes recommendations. The decision is yours. We will never design a product where AI removes an option without disclosure, or presents a single option as if no alternatives exist.

Financial disclosure

When Purple Mainspring has a financial relationship with an option we're recommending (a carrier, a merchant, a service provider), that relationship is disclosed before you act. We also show the reasoning. You have what you need to agree, disagree, or ask more. We earn trust by being transparent about how we earn revenue, not by hiding it.

Labeled at the source

AI-generated content is labeled at the point you're reading it, not buried in a help article or a terms update three clicks away. The same standard applies to human expert input. When a licensed professional, domain advisor, or credentialed specialist contributed to what you're seeing, that's noted, and where possible, who they are.

Honest about limits

We tell you when the AI doesn't know. A model that presents uncertainty as confidence is more dangerous than one that says nothing. When our systems lack sufficient information, when a question is genuinely ambiguous, or when the right answer is "speak to a professional," we say that: directly, in the moment you need it, not after you've already acted.

Always yours to override

No AI output is final. You can dismiss any recommendation, inspect the reasoning behind it, and choose differently without penalty. The system remembers your preference.

Earned Perspective

Every product has advisors who personally live the problem, people who would notice first if it got worse.

This is a structural commitment, not a marketing line. We don't mean advisors in the consulting sense (people who review decks and offer strategic feedback). We mean users. People whose lives are directly affected by whether the product is actually good, and who have no incentive to say so if it isn't.

A person managing a chronic autoimmune condition reviews Kitchen OS recipes before they ship. A licensed general contractor with real bid-day experience shapes the subcontractor risk analyzer. A certified trainer with clients reviews Workout Helper programming. The standard is simple: would this person be the first to notice if the product got worse? If not, they're not the right advisor.

Your Data, Your Terms

Your data is yours across every product we build, including between them.

Purple Mainspring builds multiple products. With your permission, they can share data to serve you better: your health profile from Kitchen OS informing your Workout Helper recommendations, for example. That kind of cross-product use requires your explicit, revocable consent. It is not the default, and it will never be enabled without you knowingly agreeing to it.

We will never share, sell, or broker your data to third parties without explicit, revocable consent. You are asked directly, in plain language, before it happens. It is never buried in a terms update or inferred from a pre-checked box.

You can revoke consent at any time. You can ask us what data we hold. You can ask us to delete it. We will tell you clearly what we collect, why we collect it, and what it is used for. If that ever changes, you'll hear from us directly before the change takes effect.

The Lupus Pledge

5% of Purple Mainspring's net profits goes to the Lupus Research Alliance, every year, without exception.

This commitment goes into our legal charter at incorporation. It will not require a board vote each year. It does not depend on whether it is convenient. It is public now and permanent once filed.

Our founder's partner has Systemic Lupus Erythematosus, a chronic autoimmune condition affecting over 1.5 million Americans. Across all autoimmune conditions, that number approaches 450 million globally, roughly 80% of whom are women. That experience is why health sits at the center of our earliest work, and why this commitment is unconditional.

The Lupus Research Alliance is the largest non-governmental funder of lupus research in the world. We believe the right response to a problem that has directly affected your life is not to acknowledge it and move on. It's to fund the people who are trying to solve it, durably, with no exit clause.

Built to Stay That Way

Purple Mainspring is forming as a Delaware Public Benefit Corporation. These commitments go into the charter at filing: after that, they cannot be quietly removed.

This is not a marketing statement. It is a legal structure that changes what we are permitted to do and how we can be operated. A Public Benefit Corporation is legally required to consider the interests of all stakeholders, not just shareholders. Our commitments to users, to the Lupus Research Alliance, and to ethical AI governance are written to be charter-level obligations, not policies that can be quietly revised.

Companies change. Investors push for margin. Acquirers rationalize commitments away. Boards vote. The PBC structure exists precisely because "we promise" is not enough. We chose this structure before we incorporated, before we had investors, before we had revenue, and before we had any commercial reason to appear credible. That's the point — and publishing the charter before the filing is how we make the choice checkable.

If we ever seek to amend these commitments, that process will be public, and we will tell you directly. We do not expect to.
