LogBook Terms of Use
LogBook is a record you keep. It measures what it can see in a photograph of a paper target and stores what you tell it about your rifles, your loads and your sessions. It does not make your rifle shoot, and it does not know whether what it tells you is true of the next shot. These terms set out what Pennanti promises and what remains yours.
Summary
- Downloading or using LogBook means you accept these terms.
- LogBook is free for one firearm and one load work-up. LogBook Pro is a yearly subscription, billed by Apple, that removes both limits. It renews automatically until you cancel it in your Apple Account settings.
- Nothing you record is ever deleted because a subscription ends, and you can always export it.
- Measurements and corrections are information, not instruction. Verify them on paper.
- Safe firearms handling is yours, always, and nothing in the app changes that.
- Your data lives on your device and in your own iCloud. Keep your own backups.
- Pennanti LLC is a South Carolina company, and South Carolina law governs these terms.
Who you are agreeing with
LogBook is published by Pennanti LLC, a South Carolina limited liability company. "Pennanti", "we" and "us" mean that company. "You" means the person using the app.
This agreement is between you and Pennanti. It is not with Apple. Apple is not responsible for LogBook or for anything in it.
Your licence
Pennanti grants you a personal, limited, non-transferable, revocable licence to use LogBook on Apple devices that you own or control, as permitted by the App Store Terms of Service. You may use it for your own shooting, and for commercial instruction or gunsmithing if that is your trade.
You may not sell, rent, sublicense or redistribute the app, reverse-engineer or decompile it except where law permits that regardless of what this agreement says, or strip out its notices and pass the result off as your own. You may not use it to build a competing product.
LogBook, its name, its icon and its measurement work are Pennanti's property. The licence gives you the use of the app. It does not transfer ownership of any of that.
Your logs, your photographs and your measurements are yours. Pennanti claims nothing in them.
LogBook Pro
LogBook is free to download. The free version keeps a full record for one firearm and one load work-up, with every feature and unlimited loads.
What it is. LogBook Pro is an auto-renewing subscription that removes both limits: you can keep as many firearms and load work-ups as you like while it is active. It is sold and billed by Apple through your Apple Account, not by Pennanti.
Price and billing. The price and the billing period (one year) are shown in the app, in your local currency, before you subscribe. Payment is charged to your Apple Account when you confirm, and again at the start of each new period.
Renewal and cancellation. Your subscription renews automatically at the end of each period unless you turn off auto-renewal at least 24 hours before the period ends. You manage and cancel it in your Apple Account settings; the LogBook Pro card in the app's Settings has a Manage Subscription button that opens them. Cancelling stops the next renewal. You keep Pro until the end of the period you have already paid for. Deleting the app does not cancel a subscription.
Price changes. Pennanti may change the price of LogBook Pro. A change applies from your next renewal, never to a period you have already paid for. Apple tells you about a price change before it applies, and where the law or Apple's rules require it, a price increase does not apply to you unless you agree to it.
Restoring. Your subscription belongs to your Apple Account. On a new device, or after reinstalling, tap Restore Purchase on the LogBook Pro screen or in Settings.
Refunds are handled by Apple under its own policy. Pennanti cannot issue, refuse or expedite them, though we will help you find the right place to ask.
Family Sharing is not available for LogBook Pro.
What a subscription pays for. A subscription pays for LogBook Pro while it is active, as it exists then and in whatever updates Pennanti chooses to release. It is not a promise that LogBook will be updated, supported or offered on the App Store indefinitely, or that it will run on every future version of iOS. If Pennanti stops offering LogBook Pro, it will stop renewing, and you will not be charged again.
Your records are never held to ransom. Whether or not you subscribe, and whatever happens to a subscription, nothing you record is deleted, and you can always read and export everything you have logged, including the whole logbook and CSV export.
What LogBook measures, and what it does not know
LogBook calculates figures from the shots you mark on a photograph: extreme spread, mean radius, group size in inches and MOA, and scope corrections in clicks. It is worth being exact about what that means.
The app measures the photograph. Its output is only as good as the image, the scale you give it and the marks you place. A target shot at an angle, a bad reference measurement, torn paper, a keyholed hit, two shots through one hole, poor light: any of these change the number, and LogBook cannot always tell that they have. Check your marks before you trust what it calculated.
Scope corrections are arithmetic performed on the group it measured and the values you entered for your optic. If the click value, the distance or the point of aim you entered is wrong, the correction will be wrong, and it will look exactly as confident as a right one.
Zero targets place a circle where a group should land at a short distance for a longer zero. That position comes from a simplified drop calculation using the sight height, ballistic coefficient and muzzle velocity in your logbook, or that you enter. If any of those is wrong, the circle is wrong, and an error at 25 yards grows about four times by 100. Confirm every zero at the distance it is meant for. LogBook is not a ballistic solver and does not give firing solutions.
Load work-ups record the charges, velocities and groups you enter or import. LogBook draws them with their uncertainty. It does not recommend a charge, and its pressure-signs checklist is a record of what you looked for, not a determination that a load is safe. Handloading is dangerous. Use published load data from the component manufacturers, start below their maximums, and work up as they direct. Nothing in LogBook replaces their data or your own judgement.
Round counts, barrel life figures, cold bore history and maintenance notes are records of what you entered. They are not an inspection, and they are not a warning system. LogBook will not tell you that a barrel is finished, that a part is worn or that a rifle is unsafe, and you should never treat its silence as an assurance that anything is sound.
Use the app's output as a starting point and confirm it on paper before you rely on it for anything that matters.
Safe and lawful use
Safe firearms handling is entirely your responsibility, and using LogBook does not alter it in any way. The app is a notebook. It is not instruction, training, or a substitute for either, and nothing it displays should be read as telling you a firearm is safe to fire or safe to handle.
You are responsible for complying with the laws that apply where you are: laws on owning, possessing, transporting and using firearms, on ammunition and components, on handloading, and on where you may shoot. Those laws vary between countries, states and towns, and they change. Pennanti does not advise you on them, and keeping a record in LogBook neither creates a legal right nor satisfies a legal obligation.
Do not use LogBook to plan or record harm to anyone, or in the course of any crime.
Your data, and your backups
LogBook has no server. What you record stays on your iPhone or iPad and, if iCloud is enabled, in your own private iCloud container. Pennanti cannot see it, cannot recover it and cannot restore it for you. How your information is handled is set out in the Privacy Policy, which forms part of these terms.
Because we hold nothing, we can replace nothing. If your device is lost, wiped or damaged, or if you delete the app or its iCloud data, your logs go with it. Keep your own backups. LogBook exports the whole logbook, with photographs, and individual logs as CSV from inside the app, and that export is the copy you control.
Warranties
LogBook is provided as it is, without warranty of any kind. Pennanti does not warrant that the app will be uninterrupted or error-free, that its measurements or calculations will be accurate or suited to any particular purpose, or that defects will be corrected. To the fullest extent the law allows, Pennanti disclaims all implied warranties, including merchantability, fitness for a particular purpose and non-infringement.
Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you. Where a warranty cannot be disclaimed, it is limited in duration to the shortest period the law permits.
Any warranty that does apply is Pennanti's obligation and not Apple's. If LogBook fails to conform to a warranty that applies to it, you may notify Apple and Apple will refund the purchase price; beyond that refund, Apple has no warranty obligation for the app of any kind.
Liability
To the fullest extent the law allows, Pennanti is not liable for indirect, incidental, special, consequential or punitive damages, or for lost data, lost profits or lost opportunity, arising out of your use of LogBook, including any decision you made in reliance on a measurement, a correction or a record it produced.
Pennanti's total liability to you for any claim relating to LogBook is limited to the amount you paid Pennanti for it in the twelve months before the claim arose, or twenty-five United States dollars, whichever is greater.
Nothing here limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, or for fraud. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
Apple
Apple has no obligation to furnish any maintenance or support for LogBook. Support is provided by Pennanti, by email, at the address below.
Apple is not responsible for addressing any claim you or a third party makes about LogBook or your possession or use of it, including product liability claims, any claim that it fails to conform to a legal or regulatory requirement, and claims arising under consumer protection or similar legislation. Apple is not responsible for the investigation, defence, settlement or discharge of any claim that LogBook infringes a third party's intellectual property.
By using LogBook you represent that you are not located in a country subject to a United States Government embargo or designated by the United States Government as a terrorist-supporting country, and that you are not on any United States Government list of prohibited or restricted parties.
If you use LogBook alongside another application or service, you must comply with that third party's terms as well as these.
Apple and Apple's subsidiaries are third-party beneficiaries of these terms, and on your acceptance of them Apple has the right to enforce them against you as a third-party beneficiary.
Changes
These terms may change as the app changes. When they do, the date at the top changes with them, and a material change will be notified in the app or on this page before it takes effect. Using LogBook after a change means you accept it. If you do not, stop using the app.
Pennanti may also change, suspend or discontinue features of LogBook. What that means for a LogBook Pro subscription is set out in the LogBook Pro section above.
Ending this agreement
You may end this agreement at any time by deleting LogBook. Deleting the app does not cancel a LogBook Pro subscription, so cancel it in your Apple Account settings first, and it does not refund one; refunds are Apple's to decide, as described above.
Pennanti may end it if you materially breach these terms. Because the app runs on your device and we hold none of your data, ending the agreement does not delete anything you have recorded; it ends your licence to use the app, and you should delete it.
The sections on warranties, liability, governing law and Apple survive the end of this agreement.
Governing law
These terms are governed by the laws of the State of South Carolina, United States, without regard to its conflict of law rules. Any dispute arising out of them or out of LogBook is subject to the exclusive jurisdiction of the state and federal courts located in South Carolina, and you consent to that jurisdiction.
If you are a consumer resident elsewhere, this does not deprive you of the protection of mandatory consumer law in your own country, or of the right to bring proceedings where that law entitles you to.
If any part of these terms is held unenforceable, the rest stays in force.
