Questions
Is it free?
Yes. Sakura Focus is free to install. Pro is an optional upgrade. The Free vs Pro table above lists exactly what each plan includes.
Do I need an account?
You can use the timer without signing in. Sign in to save your focus sessions, statistics, and grove to your account.
Can I change the focus and break intervals?
Yes. In Settings you can set the focus duration, short and long breaks, and how many sessions come before a long break. You can also give a focus category its own duration, which overrides the default while that category is selected. Custom intervals are free; auto-starting the next session requires Pro.
How do I upgrade to Pro?
Start the upgrade from inside the extension. It opens checkout with your account attached, so your account is properly linked as Pro.
Will Pro auto-renew?
Monthly and yearly plans renew automatically. Cancel anytime from Manage Subscription in the extension. Lifetime never renews.
What does lifetime mean?
A single payment grants Pro access permanently — no renewals, no expiration.
What happens if I cancel?
Your sessions and grove stay intact. You keep Pro until the period ends, then return to Free limits (90-day history, fewer categories, and the free species).
Refunds?
30-day, no-questions-asked refund via LemonSqueezy.
