120+ curated tweaks that never touch your security. Every change journaled, every change reversible, and a before/after report that proves what you gained.
One-time purchase · lifetime license · 2 PCs · works offline
Every tweak is tagged per profile, so "Select Recommended" always fits what the machine is for.
Timer resolution, GPU scheduling, mouse acceleration off, Boost Mode for game sessions, plus a launch-options library for popular titles — with honest warnings where anti-cheat forbids them.
Power plan and scheduling tuned for sustained CPU/GPU load, standby memory purging, fewer background interruptions — for local models, render queues and long-running agent work.
Debloat without breakage: ads and suggestions off, telemetry down, snappier Explorer — while updates, Defender and everything that keeps you safe stay untouched.
From checkout to an optimized machine in minutes — with an escape hatch at every step.
Secure checkout via Lemon Squeezy. EU VAT handled, invoice included.
Your license key and download arrive by e-mail, delivered with your order.
Paste the key once. A System Restore point is created before anything changes.
The Prove It report shows before vs. after. Not happy? Revert All puts everything back.
The core promise: you can see what changed, and you can always go back.
Captures a hardware and performance baseline, then shows exactly what improved after tuning — exportable as an image for the skeptics.
Every applied tweak lands in a journal with its own undo. One button reverts the entire session — no "what did it even do?"
Temporary game-session tuning: timer resolution, standby purge and keep-awake — active while you play, gone when you stop.
Registry, services, power, network, debloat — each with a plain-language description, a risk label, and an honest note when something is situational.
One purchase, two machines, hardware-locked without being fragile: one component swap won't eat your activation. Works offline after activation.
The app phones home exactly never. Update check and license validation only run when you use them — and the app opens fine without internet.
Straight from the app — this text ships inside Daito's Opti, word for word.
"This tool NEVER touches Windows Defender, SmartScreen, UAC, the firewall, CPU security mitigations, boot settings, or Windows Update (pausing restarts is the most it does). Every tweak is reversible or says honestly when it is not. Situational tweaks explain when to skip them; advanced tweaks are excluded from one-click Recommended." — Daito's Opti, Safety Model panel
Because the app is not yet signed with a code-signing certificate — those cost hundreds of euros per year and we're a small operation. The warning says "unknown publisher", not "malware". Click "More info" → "Run anyway". The full PowerShell source is readable on your own disk, so you (or anyone you trust) can verify exactly what it does. Code signing is on the roadmap.
All sales are final. Digital license keys are delivered and usable immediately, so at checkout you agree to immediate delivery and waive the EU 14-day withdrawal right, as EU law allows for digital content. Before buying, read the safety model above — and note that every change the app makes can be reverted with one click, so trying it is genuinely low-risk. Something broken on your machine? Mail support and we will fix it with you.
Two. The license locks to a machine fingerprint (hashed — we never see your hardware serials). You can free a slot yourself from inside the app (About → Deactivate) when you replace a PC, and a single component upgrade won't cost you an activation.
Yes. Activation needs internet once; after that the app opens instantly with no network check blocking you — airplane mode, LAN party, offline build rig, all fine. Revalidation happens silently at most once a week when a connection happens to be there.
No. The safety model above is a hard rule in the code: security surfaces are off-limits. For game launch options, titles with strict anti-cheat show a warning instead of options.
The license system stores a hash of your key, hashed hardware identifiers (never raw serials), a short machine hash and activation timestamps. Your e-mail is used for key delivery and support. Full details in the privacy policy.
