LogBook Privacy Policy
LogBook has no server. Your rifles, loads, sessions and target photographs stay on your iPhone or iPad and, if you have iCloud enabled, in your own private iCloud storage. Pennanti LLC cannot see any of it.
Summary
- LogBook collects nothing about you and sends nothing to Pennanti.
- There is no account and no password.
- No analytics SDK, no advertising, no third-party trackers.
- Photographs are processed on the device and are not uploaded to Pennanti.
- LogBook Pro is bought through Apple. Pennanti never sees your payment details.
- If you email support, we have your address and your message, and nothing else.
What the app stores, and where
LogBook stores what you enter and what it measures: rifles, optics, suppressors, round counts, loads and lot numbers, sessions, the place you shot (as a name, never coordinates), distances, conditions, target photographs, and the measurements taken from them.
This is held on your iPhone or iPad. If iCloud is enabled for LogBook, a copy is also kept in your own private iCloud container under your Apple Account, so that it reaches your other devices. That container belongs to you. Pennanti has no access to it and no ability to read, copy or recover its contents. Apple holds that copy under its own privacy policy.
You can export one firearm's sessions or maintenance as a CSV file, or the whole logbook as a zip of spreadsheets with every target photograph. Both exports include the place name you recorded for each session. The whole-logbook export includes serial numbers, and its Read Me says so; it goes only where you send it. Deleting the app removes the copy on the device; the iCloud copy is removed from iOS Settings, under your Apple Account. Neither step requires Pennanti.
You can also send a firearm or load to another person, as a file or as a QR code they scan from your screen, or share a picture of a measured group. A shared firearm or load carries its specification only: never the serial number, the round count, or anything you have logged.
When a rifle changes hands, Share Firearm with Log sends that one firearm with its whole history: its serial number, every session, group, target photograph, chronograph shot, maintenance entry and location you recorded with it, and the loads it was shot with. Nothing about any other firearm is included. It is a file you choose to send, and it reads like the whole-logbook export, so treat it the same way.
All of these go directly from you to whoever you choose, through iOS sharing; nothing passes through Pennanti.
Permissions
LogBook asks for three permissions, each only when you first use the feature that needs it.
Camera, to photograph a target, and to scan a firearm or load that another LogBook user is showing you as a QR code. You can also measure a target you photographed earlier, which uses the iOS photo picker: it hands LogBook the single image you choose and gives it no access to the rest of your library.
Add to Photos, only when you choose Save Image on a group or load comparison picture. This lets LogBook add that picture to your library. It cannot see, read or change anything already there.
Location, only when you tap Fill from Weather on a session whose Location box is empty. LogBook asks iOS for one approximate position, to within about 100 metres, and sends it, with the hour you asked about, to Apple Weather for the temperature, humidity and pressure at the range. Apple's map service turns it into a place name, such as a town and state, and that name is all LogBook keeps; the coordinates are never stored. Permission is only while you are using the app, never in the background. If you would rather not share your location, type the range or town into the Location box and Fill from Weather uses that instead, with no permission at all.
A photograph taken by your camera may carry location in its own metadata, which iOS Settings controls.
Any of these permissions can be declined or revoked in iOS Settings. Declining one removes only the feature that needs it: without the camera you can still measure photographs you already have, without Photos access you can still share a picture rather than save it, and without location you can still type the place for Fill from Weather.
Tracking
LogBook contains no analytics SDK, no advertising SDK, no attribution or marketing SDK, and no third-party tracker. It does not use the Advertising Identifier and does not present the App Tracking Transparency prompt, because there is nothing to track. Pennanti does not sell or share your information, because Pennanti does not have it.
Four things happen on Apple's side. Apple reports App Store downloads and sales to Pennanti as aggregate figures that identify no one. If you subscribe to LogBook Pro, Apple takes the payment and tells the app on your device whether your subscription is active; Pennanti receives no name, card or account details, and there is no Pennanti server involved. When you use Fill from Weather, the approximate position or the place you typed goes to Apple Weather and Apple's map service to answer that one request, under Apple's own privacy policy. And if you have turned on Share iPhone Analytics in iOS Settings, Apple may pass Pennanti crash reports for LogBook. That setting is yours, and it is off unless you switched it on.
Coming: optional benchmarks
A future version of LogBook will offer benchmarks: how your velocity and groups compare with other shooters' for the same bullet in the same cartridge. It is not in the app yet. When it arrives:
- It is off until you turn it on, and nothing is sent before you do.
- The screen where you turn it on lists every field that would be sent, in plain words.
- What would be sent: the catalogue entries for your cartridge, bullet and powder; muzzle velocity, shot count and standard deviation; barrel length and twist rate; temperature, pressure and density altitude; and group size in MOA with its shot count and distance.
- What is never sent: serial numbers, locations, notes, photographs, the names you give your firearms, and charge weights. Charge weights stay out on purpose: published load data rests on laboratory pressure testing, and pooled figures from shooters do not.
- The figures go to a public database in Apple's iCloud, which LogBook reads to build the benchmarks. There is still no Pennanti server. Pennanti will also use the pooled figures to decide which cartridges, components and features to support.
- This page, and LogBook's privacy details in the App Store, will be updated before that version ships.
If you write to support, Pennanti holds your email address, your message, and anything you attached. It is used to answer you and for nothing else. It is not added to a mailing list, not used to build a profile, and not passed to anyone. It is deleted once the matter is handled, or sooner on request.
Your rights
Laws including the EU and UK GDPR and the California Consumer Privacy Act give you rights to access, correct and delete information a company holds about you. Your app data is already in your possession, on your device and in your own iCloud, so you can read, export and delete it without asking anyone. The only material Pennanti holds is support email, and a request about it is answered within thirty days.
Children
LogBook is not directed at children under 13 and does not knowingly collect information from them.
Changes
If LogBook ever gains a server, an account, a payment provider other than Apple, or a crash reporter, this page will be updated before that version ships and the date above will change with it. This policy covers LogBook and this website. It does not cover Apple, whose handling of the App Store and iCloud is governed by Apple's own policy.
