Privacy Policy

Last updated: June 2026

The short version: Everything you inspect in Sift stays on your Mac. Sift has no account, no analytics, and no telemetry. The only time it touches the network is to verify a license — and that request sends only your license key, never the content you inspect.

What Sift does with your data

Sift is a native macOS app that identifies, decodes, and explains technical artifacts (tokens, JWTs, certificates, logs, payloads, and similar) entirely on your Mac. Decoding runs locally. The AI explanation runs on Apple's on-device Foundation Models — also locally. None of the text you paste, drop, or read from your clipboard is transmitted to us or to any third party.

The one network request: license verification

If you activate a Sift license, the app contacts our payment provider's license API (Lemon Squeezy) to activate and periodically validate your license. That request contains:

your license key, and
a non-identifying instance name (e.g. Sift @ <your Mac's name>), so you can manage activations across machines.

It never contains anything you inspect. If you only use the free trial and never activate, Sift makes no network requests at all related to licensing.

Purchases

Purchases are handled by Lemon Squeezy, which acts as the merchant of record. When you buy, Lemon Squeezy collects the information needed to process payment and (where applicable) tax — for example your name, email, and billing details. We receive your email and order details to deliver your license and provide support. We do not receive or store your full payment-card details. See Lemon Squeezy's privacy policy for how they handle that data.

This website

This site is a single static page with no analytics, no advertising, no cookies, and no third-party trackers. We don't know who visits.

No tracking, no profiles

We don't build user profiles, we don't sell or share data, and there's nothing to opt out of because there's nothing being collected from your use of the app itself.

Children

Sift is a developer tool intended for adults and is not directed at children under 13.

Changes

If this policy changes, we'll update the date above. Material changes will be reflected on this page.
