These terms cover your use of blarghlabs.com and of the mobile applications published by Blargh LLC (“Blargh Labs”, “we”, “us”), including Lumber Jack. By installing or using them you agree to them. If you do not, do not use them.
Where an app is distributed through Google Play, that store’s own terms also apply to the transaction, and where the two conflict on anything to do with payment, refunds or distribution, the store’s terms win.
We grant you a personal, non-exclusive, non-transferable, revocable licence to use our apps on devices you own or control, for your own non-commercial use. You may not redistribute them, sell them, rent them, reverse engineer them except to the extent that law expressly permits regardless of contract, or strip out the parts you like and ship them as your own.
The apps, this site, and everything in them — code, artwork, text, sounds, names and marks — belong to Blargh LLC or our licensors. Nothing here transfers any of that to you.
Where an app sells anything, you are buying a limited licence to use virtual items inside that app. Virtual currency and virtual items have no real-world value, cannot be exchanged for money, and cannot be transferred out of the app or between accounts. We may change the price, contents or availability of anything on offer, and we may retire items entirely.
Purchases are processed by the app store, not by us. Refunds are handled under that store’s policy and you should raise them there first.
If we ever discontinue an app, unused virtual currency and unredeemed items go with it. We will give reasonable notice where we can.
Game progress is stored locally on your phone and we hold no copy of it. If you uninstall the app, change devices, clear its storage, or your phone fails, that progress is gone and we cannot restore it. Back-ups are handled by your device and your operating system, not by us.
This one matters more than the rest of this page, so it is in plain words.
Lumber Jack simulates tree-felling technique and models it seriously. It is still a game. It is a simplification of a real activity, it runs on a phone, and it is not training, not instruction, and not a substitute for either.
Felling trees is among the most dangerous work there is. People are killed doing it every year, including experienced people. Do not attempt to learn it from this app, do not use it to decide whether a real tree is safe to cut, and do not treat anything it shows you as advice. Get real training from a qualified instructor, use proper protective equipment, and follow the law where you live. We accept no liability for anything anyone does with a real chainsaw.
Our apps and this site are provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that they will be uninterrupted, error-free, or that defects will be corrected.
To the fullest extent the law allows, Blargh LLC is not liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, data or goodwill, arising from your use of our apps or this site. Where liability cannot be excluded, it is limited to the greater of the amount you paid us in the twelve months before the claim, or ten US dollars.
Some jurisdictions do not allow these exclusions. Where that is so, they apply to you only as far as they are permitted.
We may update these terms; if we do we will change the date at the top. Continuing to use the apps after a change means you accept it. We may suspend or discontinue any app at any time. You can end this agreement whenever you like by uninstalling.
These terms are governed by the laws of the State of Colorado, United States, without regard to its conflict-of-law rules, and the courts there have exclusive jurisdiction, save for any rights you have to bring a claim locally that cannot be waived.
