The app
Boo is provided by Demoncade. You may install and use the free version on any number of your own computers. Machine translation, dictionary entries and speech are generated automatically and can contain mistakes, so don't rely on Boo alone for legal, medical or other critical translations.
Boo Pro
- Pro is sold as a monthly subscription, a yearly subscription, or a one-time lifetime license, through Lemon Squeezy, our reseller and merchant of record. Its buyer terms cover payment, taxes and refunds.
- A license is for one person. It can be active on up to 3 computers at a time; deactivate it in Boo → ✦ Pro to move it.
- Subscriptions renew automatically until you cancel. After you cancel, Pro stays active until the end of the paid period.
- Lifetime licenses include all updates to Boo for as long as Boo is offered.
- Refunds: if Pro doesn't work for you, email us within 14 days of purchase for a full refund.
Fair use
Please don't share license keys publicly, resell them, or try to get around the license check.
Open-source components
Boo includes open-source software and data under their own licenses. See the third-party notices.
Warranty & liability
Boo is provided "as is", without warranties of any kind, to the extent the law allows. Our total liability for any claim is limited to the amount you paid for Boo in the 12 months before the claim.
