Terms of Service

The terms we sell a key on, what the program does, and how to get your money back.

In effect from 11 August 2026
The short version
  • You buy a key once and it works on one computer — no subscription, no renewals.
  • Not for you? 14 days to get your money back, no reason needed.
  • The program changes Windows settings, and creates a restore point before it does.
  • Reselling keys and faking invites are not allowed — accounts get blocked for it.

01What this document is

This is an agreement between you and the owner of the FlowSync service — a private individual who runs the flowsync.cc site and the program of the same name.

It takes effect when you create an account, buy a key, or run the program. If you disagree with any part of it, simply do not use the service.

How we handle your data is covered separately, in the privacy policy. It forms part of this agreement.

02What FlowSync is

FlowSync is a Windows program that tunes the system for games, Counter-Strike 2 above all. It turns off unnecessary services and adjusts power, network, and scheduler settings — the same things an experienced user would do by hand, only faster and without the risk of missing something.

We sell a tool, not a frame rate. How much performance improves depends on your hardware, your version of Windows, and what else is running on the machine.

03Your account

  • One person, one account. Use a real email address — account recovery depends on it.
  • Your password is your responsibility. We will never ask for it, in chat or by email.
  • If someone else has got into your account, tell us straight away.
  • You can delete your account at any time. The key stops working along with it.

04Key and licence

Buying a key gives you the right to use the program — you are not buying the program itself and acquire no rights to it.

  • One key, one computer. On first activation the key binds to your hardware and will not work on another machine.
  • No expiry. The key does not run out; there is nothing to renew and nothing more to pay.
  • Updates are included. New versions cost nothing extra — though we do not promise to keep releasing them forever.
  • The key is personal. It cannot be transferred, gifted, or resold.

Changing computer or doing a major hardware upgrade? Write to support and we will re-bind the key. This is free, within reason: if the requests start coming one after another, we may decline.

05What the program does to your computer

This is the most important section — read it even if you skimmed the rest.

FlowSync changes Windows system settings. It creates a restore point beforehand, and every setting can be rolled back. But you apply them to your own computer at your own risk.

  • The program does not touch game files and does not interfere with the game itself — it configures Windows, not Counter-Strike 2. It is not a cheat and does not interfere with gameplay.
  • Turning off some Windows services can change how other programs behave. If something no longer works the way it did, roll back to the restore point.
  • Do not run the program on a work computer or someone else's machine without the owner's permission.
  • It is worth backing up important files before making significant changes. That is basic caution, worth observing with any program of this kind.

06Payment

A key is sold for a single payment. The current price is on the purchase page — we do not repeat it here, so this document cannot drift out of step with reality.

Payment goes through Telegram. Card numbers and payment details never reach us: the payment provider handles them and we only receive confirmation that the payment went through.

The key is issued immediately after payment. If that did not happen, write to support and we will sort it out by hand.

07Refunds

14 days from purchase, no reason required. It did not suit you, it did not help, you changed your mind — any of those is enough.

Message us on Telegram at @optimizewindows_bot and say you want a refund. We reply within 3 working days, and the money goes back the same way you paid.

After a refund the key stops working — that is only fair to the people who do pay.

We may refuse a refund if the key was resold or used to get around restrictions — that is, in cases of clear abuse. An ordinary buyer has nothing to worry about here.

08Invite program

When a friend arrives through your link and buys a key, you get a bonus. The amount and your current balance are shown in your account.

  • You cannot invite yourself — second accounts, throwaway emails, and friends signing up for show do not count.
  • Spam, advertising in our name, and promising things the program does not do are all forbidden.
  • A bonus for someone who then gets a refund is cancelled.
  • If invites are faked, the bonuses are wiped and the account is blocked.

09What is not allowed

  • Reverse-engineering, decompiling, or modifying the program.
  • Bypassing the key check, generating keys, or using someone else's.
  • Reselling your key or access to your account.
  • Passing our program off as your own, or distributing modified builds of it.
  • Hammering the site with automated requests or trying to reach other people's data.

10Warranties and liability

The program is provided "as is". We build it honestly and use it ourselves, but we cannot promise it will suit every computer or deliver any particular performance gain.

We are not liable for indirect losses — lost profit, a ruined match, time spent. If we are found at fault, our liability is limited to the amount you paid for the key.

We are not responsible for decisions made by third parties: how Windows, Telegram, or payment systems behave, or what the game's developers do.

The site and the service may be temporarily unavailable — because of an update, a failure, or an attack. We do not promise round-the-clock uptime.

Nothing in this section takes away the rights consumer protection law gives you in your country.

11Suspension of access

We may block an account and its key if the rules in "What is not allowed" or "Invite program" are broken. In that case the money for the key is not refunded.

If you think a block was a mistake, write to us. We will look into it and restore access if we got it wrong.

12We are not affiliated with Valve

FlowSync is not affiliated with, endorsed by, or working with Valve Corporation in any way. Counter-Strike 2, Steam, and other names belong to their owners and are mentioned only to explain what the program is for.

13Changes to these terms

These terms may change. The date at the top of the page will be updated and the change itself will appear in the site changelog. We announce anything important in our Telegram channel. If you keep using the service after a change, that means you accept it.

14How to reach us

Support and any questions — Telegram @optimizewindows_bot. News — our channel @flowsync_windows.

If any clause of this agreement turns out to be invalid, the rest stay in force.
