CcsSync is published by CcsSync LLC, a Virginia limited liability company. It reads a flight schedule from United's CCS+ system and writes it into a calendar you choose - Outlook (via Microsoft) or Google Calendar. This page explains what data that requires, where it goes, and what we do not do with it.
CcsSync is a Windows application that runs on your own PC and keeps its data there. It downloads your schedule directly from United to your PC, and writes it directly from your PC to your calendar; nothing schedule-related ever touches a server of ours. Buying a subscription is a separate transaction handled by a payment company, and that part involves us holding your name and email address.
Billing and licensing are handled by Lemon Squeezy, which acts as the merchant of record for CcsSync. When you start a trial or subscribe, Lemon Squeezy collects and processes your payment details. We never see or store your card number.
What we can see, in the seller dashboard Lemon Squeezy provides, is:
We use that information to issue your license key, to answer questions about your own order, and to meet tax and accounting obligations. We do not use it for marketing and we do not add you to a mailing list.
Your license key is delivered to that email address, which is why an email address is required in order to buy.
Activating a license sends two things from your PC to Lemon Squeezy's license API: the license key you entered, and the name of your computer as Windows reports it. The computer name is how a license key is tied to one PC at a time, so that deactivating here frees the seat to be used there.
Windows computer names are often something like
DESKTOP-A1B2C3D, but they can also contain a person's name if
that is how the PC was set up. If you would rather that name were not
recorded, rename the PC in Windows before activating.
No schedule data, calendar data, password or sync link is ever sent to Lemon Squeezy or to us.
Once a day, while it is running, CcsSync fetches a small file from
https://ccssync.com/updates/latest.json to find out whether a
newer version has been published. The file is a few hundred bytes and the
request contains no personal data and nothing about your schedule.
Like any request to any website, our web host records the ordinary details of it - see the next section. Nothing is downloaded or installed unless you choose to.
The pages on ccssync.com are plain HTML. There are no cookies, no analytics, no advertising, no tracking pixels, and no third-party scripts or fonts loaded from anywhere else.
The site is hosted on Cloudflare Pages. Like any web host, Cloudflare records standard server request logs - IP address, the page requested, timestamp, and the browser or application making the request - for delivery, security and abuse prevention. We do not use those logs to build any profile of you and we do not combine them with anything else on this page.
If you email support@ccssync.com, we hold that email, your address, and anything you attach to it. CcsSync's log file and diagnostic copies stay on your PC unless you choose to send them; if you do send one, it may contain your United file number, trip details and hotel information, so please only send what you are comfortable sharing.
Support email is kept only as long as it is useful for answering you and for spotting repeat problems, and is deleted within 12 months unless an issue is still open.
Everything the app stores - your encrypted CCS+ password and sync link,
your Microsoft and Google access tokens, your settings, your flight
history, its log and its diagnostic copies - lives in a folder under your
own Windows user profile (%LOCALAPPDATA%\CCSSync). The only
things that leave your PC are the ones described above: your schedule
request to United, your calendar writes to Microsoft or Google, license
activation to Lemon Squeezy, and the daily update check.
Uninstalling CcsSync removes the program but deliberately keeps
this data folder - it does not delete it. That's on purpose: once
United stops publishing a flown trip, CcsSync cannot get it back, so your
flight history is treated as something too valuable to risk losing to an
uninstall. A separate copy of your flight history is also kept at
Documents\CcsSync\Flight history.ics, for the same reason, and
that copy is likewise untouched by uninstalling or by deleting the AppData
folder above. If you want everything gone, both locations need to be
deleted by hand.
The data on your own PC is yours already - you can read, copy or delete the folders named above at any time, without asking us.
For the customer information we hold, email support@ccssync.com and we will send you a copy of it, correct it, or delete it. We will reply within 30 days.
One limit worth stating plainly: completed orders and invoices have to be kept for tax and accounting purposes, so those records are retained for as long as the law requires even after an account is closed. Deleting your information does not cancel a subscription, and cancelling does not by itself delete your information - if you want both, say so.
Each of these has its own privacy policy governing how they handle data once it reaches them.
CcsSync is a scheduling tool for airline crew members and is not directed at, marketed to, or knowingly used by children.
If this policy changes, the date at the top of this page will change with it.
