Privacy Policy

Last updated: October 8, 2026

TyTred Services LLC ("Company," "we," "us," or "our") operates the Sellmetrics platform ("Service"). This Privacy Policy describes what we collect, why, who else touches it, and the limits we hold ourselves to.

The short version

Your sales data is the most commercially sensitive thing you own. Here is what we will never do with it:

  • We do not sell it. Not to data brokers, not to advertisers, not to anyone, in any form.
  • We do not trade on it. We do not use your product, supplier, pricing or margin data to source or sell products ourselves, and we do not share it with anyone who competes with you.
  • We do not show it to other sellers. Your numbers live in a database of your own.
  • We do not read it for curiosity. Human access is limited to the narrow cases in Section 4, and it is logged.
  • We do not act in your seller account beyond the specific, opt-in features listed in Section 3 — all of which are off until you switch them on.
  • We only read in your buying accounts. The Sellmetrics Sync app and browser extension read order history in the buying accounts you connect. They never place orders, change account details or send messages.

If we ever want to do something outside this, we will ask you first — not quietly widen this page.

1. Information We Collect

1.1 Account information

1.2 Marketplace and tool credentials

To connect your accounts, you provide credentials for the platforms you choose to link:

All credentials are encrypted at rest with Fernet (AES-128-CBC + HMAC-SHA256) before storage. The key lives in the server environment, never in source control. Credentials are decrypted only in memory, only for the duration of an API call, and are never logged, displayed back to you in full, or sent to any third party.

1.3 Business data we retrieve on your behalf

1.4 Data you enter yourself

1.5 Operational records

To run the Service securely we keep an audit log of API-key usage (which key, which endpoint, when, from what IP), a record of scheduled data pulls, and application error reports. These exist for security and reliability, not analysis of your business.

1.6 Purchases from your buying accounts

If you use Sellmetrics Sync or the browser extension, they read the order-history pages of the buying accounts you sign in to (Amazon, Walmart, eBay and Woot) and send us, for each purchase:

This is used to fill in your purchase costs and inventory in Sellmetrics. We do not collect delivery addresses, and the tools only open the stores' order pages and the item and tracking pages those orders link to — they do not read your browsing, other tabs, or anything else on your computer.

1.7 Sellmetrics Sync (Windows app)

What stays on your computer. Sellmetrics Sync opens its own browser windows for your buying-account sign-ins and keeps those signed-in sessions, a copy of your synced orders, and its settings and activity log in a folder on your computer (%APPDATA%\sellmetrics-sync). Its key for your Sellmetrics account is encrypted by Windows. Your store passwords are never stored — you type them into the store's own sign-in page.

What it sends us. Your purchases (Section 1.6); each buying account's email and label, and whether it needs signing in again; the name of your computer, which you can change when you connect it; the app's version when it checks for updates; and periodic health checks — the app version, a checksum of the app's own files so we can spot a damaged or modified copy, and whether it was started with debugging tools. Health checks contain no business data.

Human-verification checks. When a store shows a "press and hold" check before your order history, the app may complete it for you with simulated mouse input, in the session you signed in to. See Section 3A of the Terms for what that can mean for your accounts.

1.8 What we do not collect

2. How We Use It

We use your information to:

We do not sell, rent, or trade your data; share it with advertisers, data brokers or marketing platforms; use it to source or sell products in competition with you; or share your figures with other sellers.

3. Actions We Take in Your Marketplace Accounts

By default, Sellmetrics only reads from your marketplace accounts. Some optional features do write, and we list them here rather than burying them:

We will not add a feature that writes to your seller account without it being clearly labelled and off until you enable it.

Buying accounts. In the buying accounts you connect to Sellmetrics Sync or the browser extension, we only read order history. We never place orders, change account details or send messages. Sellmetrics Sync may complete a store's "press and hold" human check to reach that history (Section 1.7).

4. Who Can See Your Data

4.1 Other customers cannot

Each customer's business data is stored in a separate database identified by a unique tenant ID. Your orders, costs, fees and margins are not visible to any other customer of the Service.

4.2 One shared reference table, and what is in it

We maintain a shared product-reference catalogue keyed on public identifiers (UPC, ASIN, Walmart item ID) holding product titles, brands, weights and images. This is manufacturer and marketplace catalogue information, not your business data: it contains no prices you pay, no costs, no quantities, no sales, and nothing that identifies which customer contributed an entry. It exists so that a product already identified once does not have to be looked up again. No customer's commercial data is pooled.

4.3 Our own access — the honest version

People at Sellmetrics can technically reach production data, because someone has to be able to fix it. We hold ourselves to these limits:

If you would rather we did not open your account while investigating something, say so in your support request and we will tell you what we can and cannot resolve without it.

4.4 Other Sellmetrics apps you have enabled

Sellmetrics is a suite. If you enable another app in it under the same account, that app can read the data it needs to do its job — for example, pricing tools need your costs to avoid pricing below them. This happens only for apps you have enabled on your account, and never moves data between customers.

5. Service Providers

We use a small number of providers to run the Service. They process data on our instructions and are not permitted to use it for their own purposes:

We may also disclose information where required by law, subpoena, court order, or a valid government request.

6. Security

No system is perfectly secure, and we will not claim otherwise. Section 9 describes what happens if we get it wrong.

7. Retention and Deletion

8. Your Rights

California (CCPA) — you have the right to know what we collect, use and disclose; to request deletion; to opt out of the sale of personal information (we do not sell it); and not to be discriminated against for exercising these rights.

EEA / UK (GDPR) — we process your data to perform our contract with you, on legitimate interest for security and service improvement using aggregate data, and on consent where required. You may access, rectify, erase, restrict, port, or object to processing, withdraw consent, and complain to your local supervisory authority.

9. If There Is a Breach

If a breach affects your personal information or marketplace credentials, we will notify affected users by email within 72 hours of becoming aware of it, describe what happened and what data was involved, explain what we have done about it, and tell you what to do on your side — such as rotating API keys.

10. Children

The Service is for business use and is not intended for anyone under 18. We do not knowingly collect information from children, and will delete it promptly if we learn we have.

11. Changes

We may update this policy. We will update the date above and, for any change that materially affects what we do with your data, tell you directly rather than relying on you to re-read this page.
