Terms of Service
Last updated: 2026-05-28.
What this is
OneTabFocus is a Chrome extension that helps you focus by hiding non-focus tabs during a timed session. By installing or paying for it, you agree to the following.
Trial and subscriptions
Every new install gets a 7-day Pro trial automatically — no card required. After the trial, free use is capped at 2 sessions per day at up to 25 minutes each. Pro subscriptions are billed annually and renew automatically until cancelled. Lifetime is a one-time purchase.
Acceptable use
Don't redistribute the extension code or our backend endpoints for commercial purposes. Don't try to bypass the free-tier gates by spoofing user IDs — it's against the spirit of the thing, and it disables your ability to recover Pro across devices.
Account recovery
If you sign in on a new Chrome profile or browser, use the email sign-in at /login to restore your Pro status. We send a one-time link to your email that signs you into your account.
Liability
OneTabFocus is provided “as is” without warranty. We're not liable for lost focus, missed deadlines, or any downstream consequences of using or not using the extension.
Changes
We may update these terms; we'll post the new date here when we do. Material changes will be notified via in-extension notification.
