Privacy Policy

The short version

• You own your recipes, costs, and prices. We do not sell them. We never share them with other vendors.
• We collect as little as we can: your email address, the numbers you type into the calculator, and basic technical data needed to run and secure the Service.
• We use a handful of vendors to run Plate Math — hosting, database, payments, email, and AI for the help assistant. They are listed by name in Section 4.
• If you use the AI help assistant, your question and a summary of the numbers on your screen are sent to our AI provider. Section 5 explains exactly what.
• You can export everything, and you can ask us to delete it.

This summary is for convenience. The full policy below is what governs.

1. Who we are

Plate Math LLC, a Texas limited liability company, is the controller of the personal information described here.

Plate Math LLC
1200 E New York Ave, Midland, TX 79701
Email: [email protected]

This policy covers app.getplatemath.com, www.getplatemath.com, and our related communications (the "Service"). It does not cover any third-party site we link to.

2. What we collect

2.1 Information you give us

2.2 Information we collect automatically

• Technical data: IP address, browser type and version, device type, operating system, referring page, and the date and time of your requests. We use this to serve the Service, to enforce rate limits, to detect abuse, and to debug.
• Local storage on your device. If you are not signed in, your business content is stored only in your browser and never reaches us. We also store your preferences there whether or not you are signed in.
• Cookies. See Section 8.

2.3 What we deliberately do not collect

We do not ask for and do not want: your Social Security or taxpayer ID number, your bank account credentials, your customers' personal information, health information, biometric data, precise geolocation, or government ID numbers. Please do not put any of these into the Service or the help assistant.

We do not knowingly collect information from anyone under 18. The Service is a business tool and is not directed to children. If you believe a minor has given us information, email [email protected] and we will delete it.

3. How we use it

We use your information to:

1. Provide the Service — run the calculator, save and sync your pantry and menu, generate exports, and keep your preferences.
2. Authenticate you — send and validate magic-link sign-in emails.
3. Take payment — process subscriptions and one-time purchases, handle refunds, and keep records of what you bought.
4. Support you — answer your questions, including through the AI assistant (Section 5), and follow up on a support ticket.
5. Secure the Service — detect and prevent fraud, abuse, and unauthorized access, and enforce our Terms of Service.
6. Improve the Service — understand which features are used and where people get stuck, and fix bugs.
7. Communicate with you — send service and transactional messages, and, if you have consented, marketing messages (Section 7).
8. Comply with law — meet our legal, tax, and accounting obligations, and respond to lawful requests.
9. Create aggregated, de-identified statistics, as described in Section 5.2 of the Terms. We only do this in a form that cannot reasonably identify you, your business, or your recipes, and we never publish your individual costs, prices, recipes, or sales.

Legal bases (if you are in a jurisdiction that requires them): performance of our contract with you (1–4), our legitimate interests in running a secure and improving service (5, 6, 9), your consent (7, and any optional feature we ask you to opt into), and legal obligation (8).

4. Who we share it with

We do not sell your personal information. We do not share it for cross-context behavioral advertising. We do not share your business content with other vendors.

We share only with service providers who need it to run Plate Math, under contracts that limit them to our instructions:

We may also disclose information:

• To comply with law — in response to a subpoena, court order, or other lawful request, or where we believe disclosure is necessary to protect our rights, your safety, or the safety of others.
• In a business transfer — if Plate Math is involved in a merger, acquisition, financing, reorganization, or sale of assets, your information may transfer as part of it. We will notify you by email before your information becomes subject to a materially different privacy policy.
• With your direction — anyone else you tell us to share it with.

5. The AI help assistant — exactly what is sent

This is the part people most want to understand, so here it is in detail.

When you send a message to the in-app help assistant, we send to Anthropic:

1. Your message, and the earlier messages in that conversation.
2. A summary of what is currently in your calculator. This is generated at the moment you press send, and it can include: your plan tier, unit and currency settings, your pantry items with what you paid and your cost per unit, the item you are building and its ingredients and quantities, your waste allowance, your target food-cost percentage, your item cost, suggested price, margins and overhead figures, and the names and prices of your saved menu items.
3. Our help documentation, which is the same for every user.

What is NOT sent: your email address, your name, your account ID, your payment details, your IP address, or your saved items' internal identifiers.

Why we send it: so the assistant can answer about your numbers — "why is my suggested price $14?" — instead of describing the feature in the abstract.

How it is handled: under our commercial agreement with Anthropic, your inputs and the assistant's outputs are not used to train Anthropic's models. Anthropic may retain them for a limited period for trust-and-safety purposes. See Anthropic's privacy policy at <https://www.anthropic.com/legal/privacy>.

If you would rather not use it, don't. The rest of the Service works normally without the assistant. Do not type payment card numbers, passwords, government ID numbers, health information, or anyone else's personal information into it.

If the assistant escalates to a human, we store the conversation, the calculator snapshot, the reason it escalated, and a reply-to address in our support-ticket database, so a person can pick it up. Those tickets are readable only by us — see Section 9.

6. How long we keep it

We may keep information longer where we must to comply with law, resolve a dispute, or enforce our agreements.

7. Marketing and messages

Service messages. We will always send you messages necessary to run your account — magic-link sign-ins, receipts, renewal and payment notices, security alerts, and material changes to our terms. You cannot opt out of these while you have an account, because they are part of the Service.

Marketing email. We send marketing only where permitted, and every marketing email includes an unsubscribe link that works. Unsubscribing takes effect promptly and does not affect service messages.

Text messages. If you opt in, our SMS program is governed by the separate SMS Terms. Consent to marketing texts is never a condition of buying anything. Reply STOP to any message to opt out and HELP for help. Message frequency varies. Message and data rates may apply.

Your mobile number. No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. We do not sell your mobile number and we do not give it to lead generators. All other categories of personal information are handled as described in Section 4. Information sharing with the subcontractors who support our text message program — our messaging provider, for example — is limited to what is needed to deliver the messages, and those parties may not use it for their own marketing.

Text message opt-in data is never shared or sold to anyone. This applies whether or not you have an account, and it applies after you opt out. We keep a record of your consent and any opt-out only for as long as the law requires us to be able to prove it.

8. Cookies and local storage

We use only what we need:

• Essential cookies — Supabase sets a session cookie so you stay signed in. The Service cannot work without it.
• Local storage — we store your preferences (language, currency, units, theme, layout, plan) and, if you are not signed in, your business content, entirely in your browser under keys beginning platemath..

We do not use advertising cookies, third-party tracking pixels, or cross-site trackers. If that ever changes, we will update this policy and, where required, ask for your consent first.

You can clear cookies and local storage in your browser settings. If you do so while signed out, any business content saved on that device is permanently lost.

9. How we protect it

We use industry-standard measures, including encryption in transit (HTTPS), encryption at rest through our database provider, passwordless sign-in (so there is no password to leak), row-level security so your rows are readable only by you, and least-privilege access on our side.

Support tickets are stored with row-level security enabled and no public access policies at all — no browser client, signed in or not, can read them. Only our server and our own administrators can.

No system is perfectly secure. We cannot guarantee absolute security, and you share information at your own risk. Your email inbox is the key to your account — protect it, and turn on two-factor authentication with your email provider.

If a breach affects your personal information, we will notify you and any regulator as required by law, without undue delay.

10. Your rights and choices

Whoever and wherever you are, you can:

• Access and export. Sign in and use the built-in Excel and PDF exports, or email us for a copy.
• Correct. Edit anything in the app directly, or ask us.
• Delete. Close your account or email [email protected]. We will delete or de-identify your data as described in Section 6, except what we must keep by law.
• Opt out of marketing. Unsubscribe from any email; reply STOP to any text.
• Complain. Contact us first at [email protected] — we would rather fix it. You may also contact your local data protection authority, or the Texas Attorney General at <https://www.texasattorneygeneral.gov>.

If you are in Texas (Texas Data Privacy and Security Act), California (CCPA/CPRA), or another U.S. state with a comprehensive privacy law, you may have rights to know, access, correct, delete, obtain a portable copy, and appeal a denial, and to opt out of sale, targeted advertising, and certain profiling. We do not sell personal information, do not share it for targeted advertising, and do not engage in profiling that produces legal or similarly significant effects, so those opt-outs do not apply to anything we do. We honor the rest.

If you are in the EU, UK, or another GDPR jurisdiction, you also have the right to object to or restrict processing, to withdraw consent at any time, and to lodge a complaint with your supervisory authority. Plate Math operates in the United States, and using the Service means your information is transferred to and processed in the U.S. Where required, we rely on Standard Contractual Clauses or another lawful transfer mechanism with our providers.

How to exercise a right. Email [email protected] from the address on your account. We will respond within 45 days (extendable once where the law allows). We will never charge you or treat you differently for exercising a right. An authorized agent may act for you with written proof; we may still ask you to verify directly.

11. Changes to this policy

We may update this policy. If a change is material, we will notify you by email or in the Service at least 30 days before it takes effect, and we will update the version and date at the top. Continuing to use the Service after that means you accept the updated policy.
