Utility Belt Labs — Privacy Policy

Last updated: October 29, 2026

This Privacy Policy explains what information Utility Belt Labs collects when you use our products — ListWise Pro, MarginGuard Pro, ClearRank SEO and FeeAudit (the “Services”) — how we use it, who we share it with, and the choices you have.

1. Who we are

The Services are operated by Utility Belt Labs (“Utility Belt Labs”, “we”, “us”). Contact: support@utilitybeltlabs.com (see also the Contact page).

2. Information we collect

Account information. Your email address and password. Passwords are stored hashed by our authentication provider (Supabase); we never see them in plain text.

Payment information. Subscriptions are processed by Stripe. Stripe collects your card and billing details; we receive and store only a Stripe customer ID and your subscription status. We never see or store your full card number.

ListWise Pro. Catalog CSV files you upload are stored in our database (Supabase) so you can see your scores, issues, health checks and fix checklist. This includes listing titles, bullets, descriptions, brand, category, price, SKUs, image URLs and other attributes in your file, plus any checklist notes you add. AI rewrites you generate are stored with your listings.

MarginGuard Pro and FeeAudit. Settlement and reconciliation reports you open in MarginGuard Pro or FeeAudit are processed in your browser and are not uploaded to our servers.

ClearRank SEO. When you run an analysis, the website URL (and optional business name) you enter is sent to our server, which fetches that public web page to analyze it. We do not store the fetched page after the analysis is returned. In the Reviews & Reputation tab, reviews you paste or import (including reviewer names) stay in your browser — unless you click “Draft with AI” (see section 3).

AI usage counters. For AI features we store a monthly count of AI actions per account (your account ID, the product and a number), used to enforce monthly limits.

Support emails. If you email us, we receive your email address and whatever you include in your message.

Technical data. Our hosting provider (Cloudflare) and our other providers process standard request data such as IP address, browser type and request logs to deliver and secure the Services. Our own logs record AI call usage (token counts and cost), not the content you send.

3. AI processing (xAI)

Some features use artificial intelligence provided by xAI (model: Grok). AI is only used when you click an AI button, for example:

  • ListWise Pro AI rewrite / AI analysis: the listing’s text (title, bullets, description, brand, category, attributes and related fields) is sent to our server and to xAI to generate the result.
  • ClearRank AI fixes: content from the website you asked us to analyze (for example its title, meta description, headings and the issues found), plus the business name you entered, is sent to xAI to word the fixes.
  • ClearRank “Draft with AI” (Reviews & Reputation): that one review — its text, star rating and reviewer name — plus the business name, contact and sign-off you entered, is sent to our server and to xAI to write a reply draft.

Nothing is sent to xAI unless you use an AI feature. xAI processes this data to return the result. How long xAI keeps API data, and whether it may use it, is governed by xAI’s own terms and policies — see xAI’s Privacy Policy (https://x.ai/legal/privacy-policy) and its terms for API customers (https://x.ai/legal/terms-of-service-enterprise). We do not make any additional promises on xAI’s behalf. AI results may be inaccurate; review them before you use them.

Do not include sensitive personal information (for example health or financial details about a customer) in text you send to an AI feature.

4. What stays in your browser (localStorage)

We use your browser’s local storage — not cookies for tracking — to remember settings on your device:

  • MarginGuard Pro: your cost-per-unit (COGS) values and TrueProfit / PriceGuard settings.
  • ClearRank SEO: “mark as done” progress per analyzed site, saved NAP listings text, and your Reviews & Reputation business details (name, service, contact, sign-off, Place ID).

This data stays on your device. You can clear it at any time by clearing your browser’s site data for this website. We also use essential cookies to keep you signed in. We do not use advertising or third-party analytics cookies.

5. How we use information

To provide and secure the Services, process payments, enforce plan and AI limits, respond to support requests, and comply with legal obligations. We do not sell your personal information and do not share it for cross-context behavioral advertising.

6. Service providers

  • Stripe — payments and billing portal.
  • Supabase — authentication and database, including account emails sent through Supabase Auth (such as sign-up confirmation and password reset).
  • Cloudflare — hosting, delivery and security; key-value storage for AI usage counters.
  • xAI — AI results, only when you use an AI feature (section 3).
  • Cloudflare Email Routing and AgentMail — email sent to our @utilitybeltlabs.com addresses (such as support@utilitybeltlabs.com) is forwarded by Cloudflare Email Routing to our AgentMail inbox, where it is stored.

7. Retention

  • Account data, ListWise Pro listings, checklist notes and AI rewrites: kept while your account is open; deleted when you delete your account.
  • AI usage counters: deleted automatically about 40 days after they were last updated (shortly after the month they count ends).
  • Payment records: Stripe keeps payment, invoice and tax records as required for tax and accounting law (up to 7 years), under Stripe’s own policies. We keep your Stripe customer ID and subscription status while your account is open.
  • Server logs: our Worker logs at Cloudflare are kept for up to 7 days. Cloudflare may keep limited network and security records under its own policies.
  • Support emails: kept for up to 2 years after our last message with you.
  • Browser storage: stays on your device until you clear it.

8. Your rights and choices

  • Access / copy: you can view and export your ListWise Pro data (CSV export) while signed in, or email us for a copy of the personal information we hold about you.
  • Correction: update your listings in the app, or email us.
  • Deletion: delete your account yourself in Settings → Delete my account (cancel any active subscription first in Billing → Manage billing). This removes your account, listings, notes and AI rewrites. We keep only records we must keep for legal or payment reasons. You can also email us from your account’s email address.
  • Cancel subscriptions: at any time in Billing → Manage billing (Stripe billing portal).
  • California and other U.S. state residents: depending on where you live, you may have the right to know, access, correct and delete your personal information, and to not be discriminated against for exercising these rights. We do not sell or share personal information as those terms are defined in the CCPA/CPRA. To make a request, email support@utilitybeltlabs.com. We will verify the request using your account email.
  • Users outside the U.S. (including the EEA and UK): the Services are intended for businesses in the United States, and your information is processed in the United States and other countries where our providers operate. You can email support@utilitybeltlabs.com to ask for access to, correction or deletion of, or a copy of your personal information, or to object to or ask us to restrict its use. We will respond as required by the law that applies to you. You may also contact your local data protection authority.

9. Security

We use HTTPS, row-level security so each account can only read its own data, hashed passwords and least-privilege server keys. No system is perfectly secure.

10. Children

The Services are for businesses and are not directed to children under 13. We do not knowingly collect their information.

11. Changes

We will post any changes on this page and update the “Last updated” date. For material changes we will notify account holders by email before they take effect.
