Support on BoostyA FEW DETAILS
Before you start
Where is my profile data stored?
On your PC. This version does not require an account or upload profiles and sessions to an authentication server.
How do built-in updates work?
Open the updates panel in the app and check for a new version. Updates come from updates.multispace.space, not GitHub. The installer is checked before installation. You confirm the download and restart; no backup encryption password is required.
What does WebRTC UDP require?
A SOCKS5 provider with UDP ASSOCIATE support. A successful proxy DNS test does not guarantee access to every STUN server. Check your provider separately.
What are the Beta limitations?
This build supports up to five profiles. Fingerprint settings are experimental and do not guarantee passing third-party anti-fraud checks. Bugs and limitations are possible.
Where can I report a problem?
Use the Feedback section in MultiSpace to prepare a bug report or feature suggestion. Include the app version and steps to reproduce the problem. Keep passwords, cookies and private profile data out of reports.
Is the application source code public?
No. Downloads contain the application installer and release checksums. The application source code is not published.
What website statistics do you collect?
We use Cloudflare Web Analytics to measure website visits, page views and performance without analytics cookies. Website download links count download starts separately from automatic updates. Our download counter stores the time and app version, not IP addresses, cookies or browser profile data. A download start does not confirm a completed download or installation. Repeated clicks and automated traffic may affect counts.
