How we handle your data and protect your privacy.
Vesper Client is committed to protecting your privacy. We believe in minimal data collection — your data stays on your machine.
We do not collect any analytics, usage data, or telemetry from the launcher or website.
We don't use cookies or any tracking technologies on this website.
No registration required. We don't have our own user accounts — you use your Microsoft account.
Vesper uses Microsoft OAuth2 authentication. You only need your Microsoft account — no custom account registration required.
Your credentials are handled securely by Microsoft's services — we never see or store your password.
Only an access token is stored locally on your device to keep you logged in. This is your login session — nothing else.
Vesper Client may interact with third-party services to provide mod and resource features:
These services have their own privacy policies when you use them through Vesper.
If you enable Discord Rich Presence, Vesper only communicates with your local Discord client. No data is sent to our servers.
Since we don't collect or store personal data, there's minimal data subject rights concerns. If you contact us, any information provided will be used solely for communication regarding your inquiry.
