Your logbook, on all your devices, seamlessly synchronized.

With a single Safelog subscription, you can use Safelog simultaneously on any or all of your supported devices, including computers, phones, and tablets, as well as directly through the SafelogWeb.com web interface.

Safelog is designed from the ground up to provide maximum flexibility, redundancy, availability, and long-term future-proofing.

When you get a new device, bringing your Safelog logbook onto it is simple. Install the appropriate Safelog app or software, start it, enter your username and password, and synchronize. Your logbook data is then downloaded to the new device.

Better still, each Safelog client stores a complete local copy of your logbook. This provides another layer of redundancy and means that important day-to-day functions such as viewing your logbook and logging flights remain available even when you do not have an internet connection.

A robust architecture designed for the long term.

At the heart of Safelog is a standards-based hub-and-spoke data architecture. This is one of the important engineering decisions that has helped Safelog remain flexible and dependable as computers, mobile devices, operating systems, and aviation technology have changed over the years.

Safelog is professionally engineered as an integrated system. Its underlying protocols and architecture allow us to add features, support new devices, and evolve the product without tying your logbook to a single piece of hardware or one particular computing platform.

Your pilot logbook is a lifetime document, and Safelog is designed to grow with you.

That is worth considering carefully when comparing electronic logbooks. Safelog has been providing electronic pilot logbook services since 1997 and has been used by many tens of thousands of pilots. For something as important and long-lived as your flight records, proven availability, redundancy, engineering quality, feature depth, and adaptability matter enormously.

In Safelog's hub-and-spoke architecture, the spokes are the individual Safelog client apps you can install on your computers, phones, and tablets. The hub consists of our professionally managed cloud infrastructure, which securely stores, manages, and synchronizes your data between those devices.

What happens when you click "Sync"?

When you synchronize a Safelog device, the app communicates with the central Safelog servers. In our client applications, the synchronization process is typically identified by our standard purple synchronization indicator.

Conceptually, the process works like this:

• Your changes are uploaded. New flights, edits, and other changes made on the device are sent to the Safelog servers.
• Your changes are combined with the data already in your Safelog account. If the same information has been edited on more than one device, Safelog uses synchronization logic and timestamps to reconcile the changes. Genuine conflicts are extremely unusual in normal use, even among pilots who regularly use Safelog on several devices.
• Your current logbook is downloaded back to the device. Safelog clients are not merely thin interfaces to a website. They are full-featured programs that maintain a complete local copy of your logbook data.
• Important application data and usability updates can also be synchronized.
• A Full Sync can retrieve larger supporting-data updates. On Safelog versions that offer both a faster basic synchronization and a more comprehensive Full Sync, the latter may also update items such as airport and aircraft-type databases.

Synchronization normally takes only a few moments. A Full Sync can occasionally take longer when substantial supporting-data updates are being downloaded.

You do not need to be online to log flights, view your logbook, or perform many everyday tasks.

Each Safelog client for PC, Mac, iPhone, iPad, and Android is a fully fledged electronic logbook application in its own right. It is not simply a thin shell that requires a constant connection to a central website.

This has some important practical benefits:

• A complete copy of your logbook data is stored on each synchronized Safelog device. Your important flight records can therefore be available locally on your computer, phone, or tablet.
• You can log flights, edit flights, add aircraft, people, and airports, view your logbook, run many reports, and perform a wide range of everyday logbook functions without an internet connection.

Some less frequently used functions still require an internet connection. These can include functions where cloud-based consistency is especially important, such as certain recency calculations, configuration changes, and account or setup options.

The result is an intelligent balance between connected and offline functionality. Your essential logbook data stays with you on your device, while Safelog uses the cloud when doing so provides important consistency, synchronization, or data-management benefits.

How and when should I synchronize?

• To synchronize immediately, simply select the Sync button in the Safelog app you are using.
• We recommend synchronizing regularly. This keeps your cloud copy current and provides additional protection if a device is lost, damaged, stolen, or fails. Synchronizing daily is an excellent habit when practical.
• If you are going somewhere without internet access, simply synchronize before you leave, use Safelog normally while offline, and synchronize again when you regain connectivity.
• If you are entering a large number of flights or making substantial changes, synchronize periodically as you work. This gives you additional peace of mind and avoids accumulating an unusually large amount of unsynchronized data.
• Some actions in Safelog may automatically trigger a synchronization. For example, if the app needs current cloud-based configuration information, it may synchronize first to help ensure that your data and settings are consistent.
• Some Safelog versions will remind you to synchronize if you have not done so for a while. We strongly recommend following those reminders.
• Safelog's synchronization architecture has proven itself over many years of real-world use. For pilots who have lost devices, suffered hardware failures, or had equipment stolen, having a synchronized Safelog account has on many occasions made recovering their logbook dramatically easier.
• If you enter or edit flights directly through SafelogWeb.com, there is no separate synchronization step for that activity because SafelogWeb is already directly connected to the Safelog cloud servers.

In short, Safelog combines the convenience of cloud synchronization with the resilience and flexibility of complete local logbook copies on your devices. Your logbook can be available where you need it, online or offline, while remaining synchronized across the Safelog platforms you choose to use.
