Precision. Reliability. Software Built to Last.
Winston AI by Shadowfetch
iOS and desktop applications engineered for precision, privacy, and durability. No subscriptions to track our tools. No accounts required. No compromise.
Winston AI is Shadowfetch's product line — refined apps for everyday people who want software that works exactly as advertised, stays on their device, and gets out of the way.
Built with the tools Apple ships — nothing extra, nothing tracked.
Our Apps
Every Winston AI app is a one-time purchase. No subscriptions, no accounts, no tracking. Just software that works.
Subscription Renewal Tracker
Never get surprised by a subscription renewal again. RenewGuard tracks all your recurring subscriptions in one place and alerts you before you're charged — so you can cancel what you don't use and budget what you do.

About Winston AI
A bloodhound doesn't stop once it has the scent. It follows the trail until the job is done — no shortcuts, no noise, no getting distracted. That's the operating principle behind every Winston AI product.
Winston AI is the product brand of Shadowfetch. We build iOS and desktop software for people who want tools that work, respect their privacy, and don't require an account just to open the app.
One-time purchase. Your data stays local. No subscriptions required to use our subscription tracker — or any other app we ship.
Privacy by Default
All app data lives on your device using Apple's native frameworks. We don't run servers that hold your information.
One-Time Purchase
Pay once, own it. No subscription tiers, no free trial with a paywall, no "premium" features held back.
Native Swift
Built with SwiftUI, SwiftData, and Apple's first-party frameworks. No web wrappers or cross-platform shortcuts.
Small Team
Two people. Real accountability. Every product we ship has a name attached to it and a support channel that actually responds.
Get in Touch
Whether you have a question about an app, want to suggest a feature, or are interested in what Winston AI is building next — reach out directly. No contact form, no support ticket system. Just email.
Direct Channels
Mail infrastructure is preserved for a future Winston AI newsletter. Not yet active — but it's ready when the time comes.
