Seller Margin — Privacy Policy

Last updated 20 August 2026 · Provider: Luke Biley · Contact: lukebiley@me.com

Short version: we don't collect any of your data. Seller Margin has no accounts, no servers, and no analytics. Everything you enter stays on your device.

What we collect

Nothing. Seller Margin is a fully offline calculator. The figures you type (costs, prices, fee rates) and the products you save are stored only on your device and are never transmitted to us or anyone else. We operate no backend server and have no ability to see your data.

Analytics & tracking

The app contains no analytics SDKs, no advertising, and no tracking of any kind. We do not know who you are or that you are using the app.

Purchases

If you buy Seller Margin Pro, the purchase is handled entirely by Apple through the App Store. We never see your name, payment details, or Apple ID — Apple simply tells the app whether a valid purchase exists so it can unlock Pro features. Apple's handling of that transaction is governed by Apple's Privacy Policy.

Data you can export

Pro users can export saved products as a CSV file via the iOS share sheet. That file is created on your device and goes only where you choose to send it. We are not involved.

Your data, your control

Because everything is local, deleting the app removes all of your data. There is nothing stored elsewhere to request or delete.

Children

The app is a business tool not directed at children, and it collects no data from anyone.

Changes

If this policy changes, the "Last updated" date above will change.
