Privacy Policy

Effective date: September 25, 2026

App Machine SIA, Latvia (“we”, “us”) makes Fastlane Preview, a Mac app that previews App Store and Google Play listings from local fastlane files, and runs this website. This policy explains what information the app and the website handle.

In short: your projects never leave your Mac, the app has no accounts and no analytics, and we don’t sell or share personal data.

Your projects

Fastlane Preview reads only the folders you choose, and only reads them: it never changes, uploads or sends your metadata, screenshots or icons anywhere. It doesn’t run your Fastfile or Deliverfile. Previews are rendered on your Mac and can’t load anything from the internet.

What stays on your Mac

To reopen your projects, the app keeps a list of the folders you opened, with macOS permission to read them, and a few preferences, such as the primary language for a project. This information stays in the app’s own storage on your Mac and is removed when you delete the app and its data. We never receive it.

Purchases

The app is free to download. Your own projects open after a one-time in-app purchase, processed by Apple under Apple’s terms. We don’t receive your name, email address or payment details.

We use RevenueCat, Inc. to verify the purchase and keep track of it. When the app shows the price or checks your purchase, RevenueCat receives a random identifier created by the app, the purchase information Apple provides, and basic technical details such as the app and macOS versions and your App Store country. RevenueCat processes this on our behalf; see the RevenueCat privacy policy. The purchase is the only reason the app goes online.

Crash reports

If you choose to share analytics with app developers in macOS settings, Apple may send us anonymous crash reports and usage statistics. You can turn this off in System Settings → Privacy & Security → Analytics & Improvements.

Email

If you write to us, we receive your email address and whatever you include in the message. We use it only to reply and delete it when it’s no longer needed.

This website

fastlanepreview.com uses no cookies, no analytics and no trackers. It is hosted on GitHub Pages; like any web server, GitHub processes visitors’ IP addresses to deliver and protect the site, as described in the GitHub Privacy Statement.

Children

Fastlane Preview is a tool for app developers and isn’t directed at children.

Your rights

Under the GDPR and similar laws, you can ask us for a copy of the personal data we hold about you, or ask us to correct or delete it. Apart from emails you send us, we hold essentially none. You also have the right to complain to the Data State Inspectorate of Latvia (dvi.gov.lv) or your local authority.

Changes

If this policy changes, we’ll update it here and change the effective date above.
