Built on four rules

Most "PC boosters" change things you can't see and can't undo. GearShift was built the other way around.

Proven onlyTweaks with no measured gain stay hidden unless you ask to see them.
ReversibleA restore point is made first, and every change has its own undo.
Security stays onGearShift never turns off Defender, firewall, updates or other protections.
PrivateNo account and no tracking. Sharing hardware stats is opt-in, never personal data.

Questions

Is it safe?

GearShift creates a Windows restore point before it changes anything, keeps an undo for every change, and never disables security features such as Defender, the firewall, Windows Update or SmartScreen.

Will it really give me more FPS?

It depends on your PC. A well-maintained PC may gain little; one with bad power settings or heavy background apps can gain a lot. The Lab (Pro) measures before and after so you can see the real difference instead of trusting a promise.

Windows says "Windows protected your PC" when I run the installer.

New apps from small developers show this SmartScreen notice until enough people have installed them. Click "More info", then "Run anyway". The warning goes away as the app builds reputation.

How does the Pro key work?

After checkout you get a licence key by email. In GearShift, open Settings > GearShift Pro > Enter key. One key works on up to 3 PCs; use "Move Pro to another PC" to free a slot.

What does the overlay show, and does it cost FPS?

FPS, 1% and 0.1% lows, frame time and a smooth graph, plus CPU and GPU load, temperatures, GPU hotspot, clocks, VRAM, power and fan, in a detailed or one-line layout. It draws in its own window and never touches the game, so it is anti-cheat safe; it uses about 1% of one CPU core. It works in borderless and windowed games.

Do I need to be online?

Only once, to activate the key. GearShift re-checks the key about once a week when you are online. Being offline never removes Pro.

What data do you collect?

None by default. If you opt in, GearShift shares anonymous hardware and performance numbers (like GPU model and FPS) to improve its estimates. Never your name, files, accounts or browsing. See the privacy policy.

Can I get a refund?

Yes. Within 14 days of purchase, for any reason, through your Lemon Squeezy receipt or by emailing us.
