YieldVault Effective Date: July 27, 2026 Last Updated: October 14, 2026
This Privacy Policy describes how Quantrolix LLC ("Quantrolix," "we," "us," or "our") collects, uses, and discloses information in connection with YieldVault, our commercial inventory yield management platform for restaurants, butcher shops, and food service operations, available as a web application, an iOS app, and a macOS app (collectively, the "Service").
This policy covers only YieldVault. It does not describe the data practices of any other Quantrolix product.
By using the Service, you agree to the collection and use of information as described in this policy. If you do not agree, do not use the Service. See also our Terms of Service.
We collect only what is needed to run your account and the Service. We do not use analytics or advertising tools, we do not track you across other companies' apps or websites, and we do not collect performance data. The one usage figure we keep is a daily count of AI requests for each store (Section 2.7).
The table below lists every data type in YieldVault's App Store privacy label. All of them are used only to provide the Service (app functionality), and none is used for tracking. The sections after the table explain each one.
| Data type (App Store label) | What it is in YieldVault | Linked to you? |
|---|---|---|
| Name | Your profile name, and supplier contact names you enter (Sections 2.1, 2.4) | Linked |
| Email Address | Your login email, supplier emails you enter, and the addresses that receive Owner view emails (Sections 2.1, 2.4, 2.5, 2.6) | Linked |
| Phone Number | Supplier phone numbers you enter on the Vendors page (Section 2.4) | Linked |
| Physical Address | Supplier addresses you enter on the Vendors page (Section 2.4) | Linked |
| User ID | Your internal account identifier (Section 2.1) | Linked |
| Purchase History | Your plan and subscription records (Section 2.2) | Linked |
| Other User Content | The business records you enter, text you send for AI assistance, and the store summaries shared through the Owner view (Sections 2.3, 2.3.1, 2.5) | Linked |
| Photos or Videos | An invoice or label photo you choose for AI extraction (Section 2.3.1) | Linked |
| Product Interaction | The daily count of AI requests for your store (Section 2.7) | Linked |
| Crash Data | Crash reports with account details removed (Section 2.8) | Not linked |
When you register and use an account, we collect:
Everything you type into YieldVault to run your business is stored so the Service can display it back to you. Depending on which parts of the product you use, this includes:
We refer to all of the above, collectively, as "Other User Content." None of it is used for anything other than running the Service for you — we do not sell it, and we do not use it to build advertising profiles. If your store joins an Owner view, summaries of it are shared as described in Section 2.5.
Chef’s Desk offers optional invoice/label capture and prioritization of recorded kitchen checks. Before either action, the app identifies OpenAI as the processor and asks you to enable AI assistance for that visit. Choosing a photo only prepares it on your device; choosing “Extract for review” sends the selected text and/or resized photo through Quantrolix to OpenAI. Choosing “Prioritize with AI” sends the displayed kitchen evidence, which can include product and supplier names, invoice references, weights, costs, dates, and recorded notes. Account passwords and payment credentials are not part of these requests.
Selected photos are used for the requested extraction; YieldVault does not add the original photo to your inventory records. Extracted suggestions remain on screen until you choose to apply them to a receiving draft and save the completed record. AI assistance alone does not change inventory. Do not include unrelated personal or confidential material. You can leave AI disabled and use manual receiving and recorded reports.
AI Insights. On the AI Insights page (Pro and Enterprise plans), nothing is sent until you choose an analysis. Choosing one sends a summary of your store's records through Quantrolix to Groq, which runs the language model that writes the recommendations. Depending on the analysis, the summary contains product names and categories with the last 30 days of waste quantities, costs and reasons; average actual and expected yields over the last 30 days; or your active recipes' names, costs, servings, menu prices and food-cost targets. It does not include your name, email address, password, or payment details.
On the Vendors page you can save a supplier's name, contact name, email address, phone number, address, and notes. We store them with your business records so they can be shown back to you in the app. YieldVault does not ask for your own phone number or home address.
Supplier phone numbers, email addresses, and street addresses saved on the Vendors page are not included in Owner view summaries or in the AI requests YieldVault builds from your records. An invoice you paste or photograph for AI extraction is sent as you provide it (Section 2.3.1), so it may show these details.
The Owner view (Enterprise plan) lets one person who owns several stores see summary numbers from each store in one place.
We send email through Resend, our email delivery provider (Section 4):
Emails already delivered, and our email provider's delivery logs, are not removed when you delete your account.
For plans that include AI features, we count the AI requests each store makes per day (by UTC date): Chef’s Desk extraction and prioritization, and AI Insights analyses. We use the count only to apply your plan's daily AI allowance. We store the store, the date, and the number of requests — not what was asked or answered. Because the count belongs to your store's account, it is declared as Product Interaction, linked to you, used for app functionality. It is deleted when your store's data is deleted (Section 7).
If the app crashes, we receive a crash report through Sentry, our crash-reporting provider, so we can find and fix the bug. This is configured to collect the minimum needed to debug a crash:
sendDefaultPii: false) in both the web app and the macOS app, so Sentry does not automatically attach IP addresses, request bodies, or similar personal data to a crash report.tracesSampleRate: 0) — we do not collect performance data.autoSessionTracking: false on macOS; the browser session integration is explicitly disabled on the web app) — we do not track app launches or usage sessions.Because of this configuration, crash data is not linked to you, and it is declared to the App Store as such.
To be explicit about the boundary: YieldVault does not perform, and this Service does not include:
We use the information above solely for App Functionality — operating the Service you signed up for:
We do not use your information to train third-party AI models, to build advertising profiles, or for any purpose beyond operating YieldVault for you.
We share the minimum information necessary with the following processors, each acting on our instructions to help operate the Service:
| Provider | Purpose | What they receive |
|---|---|---|
| Apple | Processing In-App Purchase subscriptions in the iOS app and the macOS app | Your Apple ID's payment details are handled entirely by Apple; Quantrolix never receives or stores your card information. Apple shares back a purchase/transaction identifier so we can unlock your plan. |
| OpenAI | Optional invoice/label extraction and prioritization in Chef’s Desk | Only the selected document content or recorded kitchen checks described in Section 2.3.1, when you enable assistance and choose an AI action. API content is not used to train OpenAI models by default. OpenAI may retain API inputs and outputs for abuse monitoring for up to 30 days, subject to its applicable policies. OpenAI API data controls. |
| Groq | Writing AI Insights recommendations | Only the AI Insights summary described in Section 2.3.1, when you choose an analysis on the AI Insights page. |
| Sentry | Crash diagnostics | Crash reports as described in Section 2.8 (PII, tracing, and session tracking disabled) |
| Stripe | Payment processing for the web application only | Billing/payment details for web checkout; see Section 6 |
| Resend | Sending the emails described in Section 2.6 (web subscription notices, Owner view confirmation codes, and Owner view summaries) | The recipient's email address, their name if included, and the subject and content of the email, which for Owner view summaries include store, product, and supplier names and dollar figures |
| Hosting provider | Running the application and database that store your account and Other User Content | The account and business data described in Section 2 |
Apart from these providers, your store's data is shared only with the people you choose through the Owner view (Section 2.5). We do not share your information with data brokers, advertisers, or analytics networks, and we do not sell your personal information.
See Section 2.8. In short: crash reporting exists purely to keep the app stable. It is scoped down (no default PII, no tracing, no session tracking, no identity attached) so that the data we receive when something breaks cannot be tied back to a specific person. This is why crash data is declared "not linked to you" rather than linked to your account.
YieldVault sells subscriptions through two separate channels, and they are kept separate for privacy purposes:
If you delete your YieldVault account while an Apple In-App Purchase subscription is still active, deleting the account does not cancel the Apple subscription — Apple will continue billing your Apple ID until you cancel it yourself through your Apple ID subscription settings. See Section 7 for what we retain in that situation.
How to delete your account: In the app, go to Settings → Security → Delete Account. This calls our DELETE /account endpoint.
What happens when you delete your account:
Backups: Routine database backups that already contain your data before deletion may persist for a limited time (see our Terms of Service, Section 6.5) before they are cycled out, consistent with normal backup rotation.
Emails: Emails already delivered, and our email provider's delivery logs, are not removed when you delete your account (Section 2.6).
Crash data: Because crash reports are not linked to your identity (Section 2.8), there is nothing tied to your account to separately delete from Sentry when you delete your YieldVault account.
YieldVault is business software built for restaurants, butcher shops, and food service operations, and it is not directed at children. We do not knowingly collect personal information from children. If you believe a child's information has been provided to us, contact support@quantrolix.ai and we will delete it.
Quantrolix is based in the United States, and the Service's hosting infrastructure is US-based. If you use the Service from outside the United States, your information will be processed in the United States, which may have different data protection laws than your home jurisdiction. By using the Service, you consent to this transfer and processing.
We may update this Privacy Policy from time to time, for example to reflect a change in what data a new feature collects. When we make a material change, we will update the "Last Updated" date above and, for significant changes, notify account holders by email or in-app notice. Continued use of the Service after a change takes effect means you accept the updated policy.
