Inbox Curtain

Hide your email inbox until you're ready. Free forever, no signature, nothing leaves your browser.

Your inbox doesn't need to be open all day. Inbox Curtain puts a calm curtain over your inbox list so you can write, search and work in your mail without being pulled into new messages. When you're ready, click "Show inbox" — and the curtain returns on its own after a few minutes. What it does • Hides the inbox list in Gmail and Outlook on the web until you choose to look • Lets urgent mail through: sign-in codes, verification codes and password alerts stay visible, matched by simple rules that run in your browser • Add your own urgent keywords • Hides unread counts in the tab title and folder list • Lockout hours: keep the inbox closed during a focus window you set • Daily check budget and a small history of how often you looked What it doesn't do • It never adds a signature or any text to emails you send • It doesn't read message bodies — only the subject, sender and labels already shown in the list • It collects no data and makes no network requests: no analytics, no tracking, no account. Your settings stay in your browser Free forever Hiding your inbox, urgent keywords, one lockout window, the daily budget and unread hiding are free forever, with no account and no sign-up. Pro (optional) • Unlimited lockout windows, plus strict mode that also blocks searches that would reveal the inbox • Sender and domain allowlists, plus a "Banks & payments" preset • 30-day check history • Custom auto re-hide time, and lock the Show button once your daily budget is spent US$2.99 for 30 days or US$12.99 lifetime — one-time payment, no auto-renewal, 14-day refund. Your licence code arrives by email and is verified offline, so Pro still needs no account and sends nothing anywhere. Works on mail.google.com, outlook.live.com and outlook.office.com.
