Privacy policy
Last updated 30 July 2026
LanderSync collects nothing about you. The app sends no data to us — not usage statistics, not crash reports, not your email address. There is no account to create and no analytics inside it.
That is unusual enough to be worth stating plainly, and the rest of this page explains exactly what does happen, so you can check the claim rather than take it on trust.
Who is responsible
LanderSync is published by September Media OÜ, a company registered in Estonia. If you want to reach us about anything on this page, use GitHub issues for anything public, or the contact details on the Microsoft Store listing for anything private.
The app
What stays on your computer
All of it. Specifically, LanderSync stores the following in its own application data folder on your PC:
- your Cloudflare API token, encrypted (see below);
- the folder path you selected, and your settings;
- a list of file names and content hashes for each site, which is how it works out what changed since the last publish.
None of this is transmitted to us. You can delete all of it by uninstalling the app.
Your Cloudflare API token
The token is yours, not ours. It is encrypted at rest using Windows' own Data Protection API, through Electron's safeStorage, which means it is tied to your Windows user account. It is never written to a log file, never shown in full in the interface, and never sent anywhere other than Cloudflare.
One thing you should know, because it is a limitation of Cloudflare's permission system rather than a choice we made: Cloudflare tokens cannot be restricted to a single Pages project. A token with permission to publish covers every Pages project in that Cloudflare account. LanderSync asks for the narrowest permission Cloudflare offers. If that concerns you, use a separate Cloudflare account for your landing pages.
Where the app connects
| Host | Why | What is sent |
|---|---|---|
api.cloudflare.com |
To create your Pages project and upload your files — the actual job of the app. | Your own API token, and the contents of the folder you chose to publish. Sent by you, to your own account. |
github.com |
Checking whether a newer version of LanderSync exists. Only in the version downloaded directly from GitHub — the Microsoft Store version does not do this, because Windows updates it through the Store instead. | Nothing but an ordinary file request. No identifier is attached and no account is involved. |
| The address of your own site | Checking a page is really online after publishing, so it can show you an honest status rather than assuming success. | Nothing. It is the same request any visitor's browser makes. |
There are no other connections. No analytics service, no crash reporter, no advertising network, no telemetry of any kind is present in the application.
Files you publish
The files in the folder you select are uploaded to your own Cloudflare account and become a public website, because that is what you asked the app to do. We never receive a copy and have no access to them. Once they are on Cloudflare, Cloudflare's terms and privacy policy apply to that hosting, and your relationship is with them directly.
It is worth being obvious about one consequence: anything you put in that folder becomes publicly reachable on the internet. Do not put files there that you do not want the world to read.
This website
landersync.com is itself hosted on Cloudflare Pages. It sets no cookies, runs no analytics, and has no tracking pixels or advertising.
It loads nothing from any third party. Fonts, images and stylesheets are all served from this domain. Many sites pull their fonts from Google Fonts, which quietly sends every visitor's IP address to Google; this one hosts its own copies specifically so that does not happen. Opening a page here means your browser talks to exactly one server, and it is ours.
Cloudflare, as the host, processes standard server request data on our behalf in order to serve the site and protect it from abuse. See Cloudflare's privacy policy.
Your rights
Under the GDPR you have rights of access, correction, erasure, restriction, objection and data portability over personal data a company holds about you.
In our case there is a short answer: we hold no personal data about users of LanderSync, so there is nothing to access, correct, export or erase. We have no user database, because the app has no accounts and reports nothing back.
If you believe we have handled personal data improperly you may complain to the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon), or to the supervisory authority in your own country.
Children
LanderSync is a tool for publishing websites and is not directed at children. It collects no personal data from anyone, of any age.
Changes to this policy
If this policy changes, the date at the top of the page changes with it. Because the site is open about its own history, you can also see every revision of this file in the public repository.
Verifying any of this
You should not have to believe a privacy policy written by the people it protects. LanderSync is MIT licensed and its complete source code is public, the installers are built in the open by GitHub Actions, and SIGNING.md documents how releases are produced and how credentials are handled. Every claim above can be checked against the code.
