Privacy

Your focus is not our data.

Sift’s Mac blocker makes enforcement decisions on your Mac. While a lockdown is active, it may read open browser-tab URLs solely to replace blocked pages with the Sift screen. Those URLs are not stored, logged, or transmitted.

Local data

Your blocklists, reminder, theme, and active-session state are stored locally on your Mac.

Accounts and service data

The optional account preview stores the account and profile information needed to sign you in. It is not connected to the free Mac blocker, which does not require an account or upload your blocklists.

Diagnostics

Sift does not currently ship third-party analytics or advertising trackers in the Mac app.

Questions

Read the setup and recovery guide on the support page, or use Sift’s public support tracker. Do not post passwords, private browsing history, or other sensitive information.
