Cookie Policy.

We barely use them. No tracking cookies, no ad cookies, no third-party analytics — because there are no ads and no trackers.

EFFECTIVE OCTOBER 25, 2026

The short version. ATCSTW sites use only what the products need to function: session state for signed-in tools and local storage on your device for preferences and keys you choose to keep there. There is no consent banner because there is nothing non-essential to consent to.

What we use

Essential session cookies. The Suite tool may set a minimal cookie to keep you signed in during a session. It contains a session identifier, nothing else.

Local storage (your device, not a cookie). The Suite tool stores your key on your device when you sign in, and the sites store display preferences. This never leaves your device except as the credential needed to use the tool. Clear it anytime in your browser settings — you will just sign in again.

What we do not use

No tracking cookies. No advertising cookies — there are no ads on ATCSTW properties. No third-party analytics cookies — no Google Analytics, no Meta Pixel, no fingerprinting scripts. No cross-site anything.

Third parties

Checkout runs on Stripe's pages, which operate under Stripe's own cookie practices. API responses set no cookies. If this ever changes — if a non-essential cookie is ever proposed — this page changes first and a banner appears before it ships, not after.
