mellto-tune is a Windows performance tuning utility. It may change system settings, power plans, network parameters, GPU driver settings, memory management, and related configuration.
Assumption of risk
By using mellto-tune you accept that changes can reduce stability, performance, or security on some PCs; you are responsible for backups and restore points; and the authors are not liable for data loss, downtime, hardware issues, or warranty impact.
Subscription & trial
Access requires a paid plan or an active trial. Trials require a payment method (Card or PayPal via Stripe). Standard includes 1 device. Cancel, update payment method, or download invoices in the Stripe Customer Portal (Manage). When a trial or subscription ends, the app reverts to Windows defaults - create restore points. Refunds follow Stripe / your payment method's rules; contact support for billing issues.
Anti-abuse
One free trial per machine (hardware fingerprint). Offline use is limited by a short grace period. Failed payments may enter a short past-due grace, then lock and revert. Accounts may be disabled for fraud or abuse.
