HearthVault is private by design. It is a local-first backup tool: your files stay on your own devices and your own home network. We do not run a cloud, we do not have user accounts, and we do not collect, transmit, sell, or store your personal data or the contents of your files. There is no advertising and no third-party tracking.
This policy describes how the HearthVault application (the App, we, us) handles information. It applies to your use of the App on your own devices.
To do its job, the App reads the folders and files you explicitly choose to back up, and writes copies to the destinations you choose (for example another drive, an external disk, a synced cloud folder you select, or another computer on your local network). All of this happens on your own devices and local network, under your control. The App does not send this information to us.
None. The App does not contain analytics, telemetry, usage tracking, advertising identifiers, or crash reporting that sends data to us. We do not build a profile of you and we do not receive your file names, file contents, folder paths, IP address, or device identifiers.
If you use the optional Family Mesh add-on, backup copies travel only between your own devices over your local network, in encrypted form, using a key that is generated and stored only on your devices. This data does not pass through us and is not sent over the internet by the App. You are responsible for keeping your pairing key and your network private.
If you choose to back up into a folder that is synchronized by a third-party cloud service (such as OneDrive, Dropbox, or Google Drive), the App simply writes files into that local folder; the upload and any storage are performed by that third-party service under its own privacy policy and terms. We are not a party to that relationship and are not responsible for how that service handles your data.
Because your data stays with you, its security depends primarily on your own devices, accounts, disks, and network. We encrypt Family Mesh transfers between your devices, but we cannot guarantee the security of hardware, operating systems, networks, or third-party services that are outside our control.
The App is a general-purpose utility and is not directed at children.
We may update this policy as the App evolves. Material changes will be reflected in the App and in the Microsoft Store listing, with an updated date.
