FAQ

Frequently asked questions

The short answers to the questions that come in most often. The full picture lives in the privacy policy and terms.

Does MantaRay include free VPN servers?
No. MantaRay is a VPN client. You bring your own server configuration — either a subscription URL from a provider you trust or a server you administer yourself. We do not run, sell, or resell any VPN servers.
Why is the connection slow / unstable?
Throughput and latency depend almost entirely on the server you configure: its location, hardware, the chosen protocol, and the provider's network. Try another server in the subscription, a closer region, or a different protocol (VLESS-REALITY and Hysteria2 usually behave best on lossy networks).
Where are server profiles stored?
Server profiles live exclusively on your device, in the operating system's secure storage: Keychain on iOS / macOS, EncryptedFile on Android, DPAPI on Windows, and a permission-restricted SQLite database on OpenWrt. They are never transmitted to Mantatech Ltd.
Why does MantaRay ask for the "VPN" permission?
Because the app is a VPN client, the operating system requires explicit consent before it can route your traffic through a tunnel interface. We use the platform-native NetworkExtension API on Apple devices and the standard VpnService on Android.
Can I sync my settings across devices?
On Apple devices, yes — subscription URLs and the active profile sync via iCloud's NSUbiquitousKeyValueStore if iCloud Drive is enabled for MantaRay. The data is end-to-end encrypted by Apple and never reaches our servers. On other platforms you can use the LAN handoff feature to copy a subscription between devices on the same Wi-Fi.
How do I delete the app and all data?
Uninstall MantaRayvia the standard OS flow, then remove the VPN profile (Settings → General → VPN & Device Management on iOS, equivalent screens on Android / Windows / macOS). See the account deletion page for the full step-by-step.
I think I found a security issue. Where do I report it?
Email security@mantatech.ltd with a description and a proof of concept. See the security policy for response times and PGP keys.
How do I send a bug report?
Email support@mantatech.ltd with: app version, OS version, device model, the active protocol, and the steps to reproduce. If the app is crashing, allow the in-app crash reporter to send a sanitised report — it lets us symbolicate the trace immediately.
