Prospira Tweaks
01Who you are buying from
Prospira Tweaks, run by ALEKO Marcin Lewandowski.
Prospira Tweaks is run by ALEKO Marcin Lewandowski, a sole proprietorship registered in Poland (jednoosobowa działalność gospodarcza), NIP 5581690947, REGON 367203470. Address for correspondence and complaints: ul. Widokowa 1A, 89-333 Osiek nad Notecią, Poland.
These terms cover this website, the remote optimization session, and the Prospira Tweaking Utility - the Windows 11 app, its free Entry tier and its paid Champion plans. Buying anything here, or installing and using the app, means you accept them; the app's installer and the app itself ask you to confirm that before you use it. If you are buying for a business, section 04 does not apply - except that a sole trader buying something outside their own line of work keeps the withdrawal right Polish law gives them.
Reach us at contact@prospiratweaks.com, or open a ticket from the contact page.
02What we sell
A session we perform on your PC, a 30-minute Check that changes nothing, and an app you run yourself - free, or with a paid Champion plan.
Prospira PC Optimization is done by a person over a remote connection while you watch your own screen.
Prospira Check is 30 minutes over a remote connection: a person looks at how your PC is set up and how it behaves under load, changes nothing, and tells you whether a full session is worth it for you, or what to fix first. If it finds nothing on your PC worth improving, you get what you paid for it back (section 04).
Prospira Elite is our top plan, bought once. We talk with you first and offer it only when your PC will gain from it; you then pay through a personal link we send you. It includes a Champion Lifetime licence (section 07); one session of about 3 hours in which a specialist installs a clean Windows 11 and sets up the drivers, the BIOS and the monitor, under the same rules as any session (section 05); your games measured in the app before and after that session; and, for 12 months from your purchase, up to 3 re-tunes (section 09), first place in the support queue with the Elite role on our Discord, and one free move of your licence to a new PC. The Prospira Toolbox from your session is yours to keep.
The Prospira Tweaking Utility is a Windows 11 application you install and run yourself, from the download page. The Entry tier is free. Champion - monthly, for 3 months, annual or lifetime - unlocks the paid features listed on the utility page. The app needs Windows 11, an internet connection and a Discord account to sign in with.
What each one includes, and what it costs, is on the services page and the utility page. Those pages are the offer; this page is what happens around it. Where a package is described as announced but not bookable, it cannot be bought yet and nothing on this page makes it available.
03Prices and payment
Prices are in US dollars, or in złoty in Poland, and are charged in full before any work starts.
Card and the wallets that ride on it are handled by Stripe at checkout, and we never see or hold your card number. The methods Stripe shows you depend on where you are and what you are buying; the list Stripe shows you when you pay is the authoritative one, not this sentence.
In Poland BLIK is offered too, wherever prices are shown in złoty - on the Polish version of this site and in the app. BLIK covers the one-off payments — a session, Champion for 3 months or the lifetime licence — and, where the checkout offers it, the monthly and yearly plans too, if your bank supports recurring BLIK payments; otherwise those plans are paid by card. Cryptocurrency is the one method the checkout cannot take - write to us first and we will arrange it by hand.
Prices are set in US dollars, and separately in złoty for Poland - the złoty price is its own figure, not a conversion. Paying a dollar price from an account in another currency means it is converted at a rate and with a fee that are not ours, so the figure your bank shows can differ slightly from the one on the page.
Champion monthly and annual are subscriptions. They renew at the price you agreed until you cancel, and you can cancel at any time from your account. Cancelling stops the next renewal; it does not shorten the period you have already paid for. If a renewal payment does not go through, Champion keeps working for 7 days while you update your card, and the app and an email tell you so. If it is still unpaid after that, the paid features stop, and three days later the app undoes what they changed, as when a plan ends (section 07). Champion Lifetime is a single payment - there is nothing to renew and nothing to cancel.
Champion for 3 months is a single payment too. It gives Champion for 3 months, counted from the purchase or, if a plan you already have is still running, from the day that plan ends; then it ends by itself - nothing renews and there is nothing to cancel. You can buy it again before it ends, up to four in a row, and each one starts where the one before ends. A creator's code applies to it as to any plan (section 10); personal referral links do not, and credit on your account does. Buying the monthly or annual plan while it runs does not end it: you pay at once, and the first month or year of the new plan starts the day your Champion for 3 months ends (the last one, if you bought several), so none of its days is lost. Moving to Lifetime counts what you paid for it, as below.
Elite is paid in full through the personal link, before the session is booked. The link is for you alone, and we switch it off once it is paid or if you change your mind.
Credit on your account. Some money you have already paid or earned stays on your account as credit: what you paid for a Check, for 30 days from that payment, and referral rewards (section 10), for 12 months. Credit is not a discount. It comes off a Champion plan or a Boost or Titan session by itself at checkout - never off a Check - and it goes together with a code or a discount from points. What a purchase does not use stays for the next one until it expires. A one-off payment never goes below 2 złoty or 50 cents, the least Stripe will charge. Credit stays in the currency it was paid in, so a payment that uses it is in that currency too. It cannot be paid out, exchanged for cash or passed to someone else, and it ends with your account. Your account shows what you have and until when.
Moving to Lifetime. If you move from the monthly, 3-month or annual plan to Champion Lifetime, what you have paid for that plan comes off the price, up to three months of the monthly plan (117 złoty or $27), or the unused part of your current period if that is more. The old plan then ends, with nothing more returned for it.
The launch offer, 1-31 December 2026. Champion Lifetime costs $139, or 599 złoty in Poland, until 31 December 2026, Warsaw time, and $189 or 799 złoty from 1 January 2027. Everyone who buys it in December gets the Founder role on our Discord, with its priority support channel; a refund removes the role. The first 30 people who buy it in December also get a Check for free: the Check checkout of the same account then costs nothing, while places last, and the app and this site show how many are left. The 14-day refund in section 04 applies as usual.
04Changing your mind: refunds and withdrawal
As a consumer you get 14 days - unless you asked us to start sooner and we finished the work.
As a consumer in the EU you may withdraw from a distance contract within 14 days without giving a reason. What that means depends on what you bought.
The optimization session. Cancel at any time before it starts and you pay nothing. Because a session normally happens sooner than 14 days after booking, the checkout asks you to declare two things in one unticked box: that you want us to begin inside the 14-day window, and that you understand finishing the session uses up the right to withdraw. It sits directly under the box about erasing the drive, and neither is ticked for you, and the booking will not go through until both are. Every booking asks for that declaration before we start, however it is made. Once you have made it and we complete the session, the work is done and the fee is not returned - what you paid for is hours of one person's time, and that time is spent. If you withdraw part way through, the right is still yours: you pay for the share of the work already done and we return the rest.
The Champion plans. Ask within 14 days of your first payment for a plan and we refund it - telling us what went wrong helps us, but it is not a condition. For the monthly and annual plans the 14 days run from that first payment, not from each renewal: a renewal continues a plan you already chose, and you can stop the next one at any time from your account. After a refund the licence is revoked and stops unlocking the paid features, and three days later the app undoes what those features changed - apart from BIOS/UEFI settings, which it offers to put back and never undoes on its own. The app keeps working on the free Entry tier, and anything else it changed on your PC can still be undone from inside it - apart from the changes it told you could not be undone, which section 07 lists. The Entry tier is free, so you can see how the app behaves on your hardware before paying anything.
Prospira Elite. Before your session has started, ask within 14 days of paying and we refund all of it; the lifetime licence that came with it ends. The session asks for the same declaration as any session, and for Elite it covers the whole plan: once you have made it and we complete the session, Elite is not refunded, the lifetime licence in it included. That is the one way it differs from Champion Lifetime bought on its own.
Purchases paid partly with credit. If one is refunded, the money goes back the way it came and the credit returns to your account, unless it has expired by then. If you withdraw from a Check whose credit you have already used, the part used counts as already returned to you.
The Check guarantee. If in your Check we find nothing on your PC worth improving, we return what you paid for it, in full. Ask within 14 days of the Check. What you paid for a Check otherwise stays on your account as credit (section 03), so the guarantee applies while that credit is unused, and the refund ends the credit.
To withdraw, write to contact@prospiratweaks.com and say so. You do not need a form or a reason. Card and wallet payments go back the way they came, through Stripe. A payment made in cryptocurrency cannot always be returned by the same route, so we agree that with you first - you are not left worse off either way.
05What happens in a session
It begins by erasing the drive Windows is on, so back your files up before we start.
This is the one consequence you have to meet before paying, which is why it is also on the services page and in the checkout. Programs, game installs, files on the desktop, browser profiles and passwords saved only in a browser are gone. Other drives in the PC are left alone.
You need a Windows 11 PC you are the administrator of, a stable connection, and your files backed up somewhere else. Sessions run 14:00 to 22:00 Europe/Warsaw and you pick the hour. If you are not there at the time you chose, we will wait, and then find you another slot at no extra cost. If a second booked slot goes by without a word, we may treat the session as delivered - the hour was held for you.
An Elite session follows the same rules, takes about 3 hours, and starts and ends with a measurement of your games in the app. If a re-tune needs the drive erased, we tell you first and do it only once your files are backed up.
06What we will not do
Beyond the drive we agreed to erase, we do not touch anything you have not agreed to.
Erasing the Windows drive is the one destructive thing a session does, it is agreed before anything starts, and section 05 is where it is described. Everything outside that is bounded: we do not log into your accounts, we do not read your files, we do not touch other drives, and we do not install or change anything you have not agreed to. The limits are written out on the about page, and that list is part of this agreement rather than a separate promise.
We do not promise a specific frame rate, benchmark score or percentage. Results depend on your hardware, your games and your settings, and anyone quoting you a number in advance is guessing. What we promise is the work described on the services page, done properly.
07The Utility licence
The app is licensed to you on one PC, for your own use. It changes Windows and, if you choose, BIOS settings, and one button puts back what it changed - apart from the few changes it marks as one-way before they run.
What you get. A personal, non-exclusive, non-transferable licence to install and use the Prospira Tweaking Utility on one PC, for as long as your account exists - the free Entry tier included. A Champion plan adds the paid features for as long as it is active, and a lifetime plan for as long as we offer the app. When a monthly, 3-month or annual plan ends, the app undoes what the paid features changed three days later, apart from BIOS/UEFI settings: those it offers to put back, with a restart you choose, and never undoes on its own. A lifetime plan keeps them all. You are licensed the software; you do not buy it.
One PC, one account. The app registers a one-way fingerprint of your machine, and one account holds one PC. If you change PC, release the old one from your account and sign in on the new one. A release costs $5, or 19 złoty in Poland, and can be made once every 30 days; the account page shows the price before you confirm. If your PC is locked to the account and cannot be released, write to us.
Elite. Its Champion Lifetime licence follows these same terms, and one release in the 12 months after your purchase costs nothing.
What you may not do. Resell, rent out, lend or redistribute the app, a licence, or the content the app downloads from us - the tweak lists, the BIOS settings catalogue, driver packages - which is prepared for your account and marked so that a copy can be traced back to it. Take the software apart, decompile it or get round its licence checks, except where the law expressly allows it. Script or automate requests to our servers outside the app.
It needs us online. You sign in with Discord, and the app loads its tweak lists and other content from our servers. If they cannot be reached, the features that depend on them wait until they can - but undoing a change you already made works offline. The app updates itself, and an update can be required to keep using it. If an update takes away or noticeably worsens a paid feature you rely on, you may end your plan and we refund the unused part.
What it changes, and what cannot be undone. The app changes Windows settings, services and drivers, and - only if you choose - settings in your PC's BIOS/UEFI. Before each change it records what the setting held, and Undo puts exactly that back - card by card, or everything at once from Settings with one button, BIOS/UEFI settings included. A setting that Windows or another program has changed since is left as it is. Store apps and Windows add-ons come back from the Microsoft Store and Windows Update, so putting them back needs a connection. Some actions cannot be undone, and the app marks them and asks before they run: cleaning files, uninstalling desktop programs, removing a Store app the Microsoft Store has no listing for, removing old device entries or NVIDIA's telemetry packages, installing a graphics driver, importing a registry file, and turning on System Protection to make a restore point. Microsoft Defender is switched back on from its own tile, through the same Safe Mode restart that switched it off. A BIOS/UEFI change or a service profile can stop a PC from starting, and Undo needs Windows to run: getting back may then need a restore point or a CMOS clear on the motherboard. It creates a Windows restore point the first time it runs; keep your own backups too. Which changes to apply is your choice, and you make it at your own risk.
Games and anti-cheat. Some games' anti-cheat systems react to system changes - virtualization-based security, driver settings, services. We do not control those systems, and we cannot promise that a game will not flag, restrict or ban an account because of a change you made.
Other people's software and names. Some features use or download tools made by others - a hardware monitor, a BIOS configuration utility, repackaged graphics drivers - supplied as they are available and, where they have them, under their makers' terms. The open-source parts of the app are listed with their licences on the licences page and inside the app. Microsoft, Windows, NVIDIA, AMD, AMI, Discord and the names of games are trademarks of their owners. Prospira is not affiliated with, endorsed or sponsored by any of them.
When the licence ends. It ends when your account is deleted, or if you break this section seriously and do not stop after we tell you. We will say why.
08Your account
You sign in with Discord and need to be at least 13. Under 18, a purchase needs a parent's or guardian's consent.
Thirteen is our minimum, the same as Discord's; where Discord requires more in your country, its minimum applies. The free Entry tier is yours to use from 13. Under 18, a paid plan, a Check or a session is a contract a parent or legal guardian has to agree to: by paying you confirm that they have, and the app and the checkout ask you to say so. News and offers by email need you to be 16 or over. There is no separate password here - the login is Discord's, so their terms apply on top of ours. Keep your Discord account secure; anything done through it is treated as done by you.
We can suspend an account that is used to abuse the service, to charge back a session that was delivered, to resell licences, or to get round the app's licence checks. If we do, we will tell you why.
09Support
For a session, a follow-up window in which we fix anything our work caused. For the app, help by ticket, from a person.
How long a session's follow-up window lasts depends on the package and is stated on the services page. Inside it, open a ticket and we reconnect and fix anything that came out of our work. There is no limit on how often.
Elite adds 12 months, counted from your purchase, in which you are first in the support queue and can ask for up to 3 re-tunes: remote sessions to set the PC up again after a Windows update, a new game or new hardware. What a re-tune covers depends on what happened, and we agree it with you at the start. Fixing what our own work caused never counts towards the three.
For the app, open a ticket from the contact page or send a bug report from inside the app. Most messages get an answer within 24 hours, from a person. That is what we aim for, not a guarantee we are selling you.
10Referrals and creator codes
A creator's or a friend's code takes 10% off. Three friends who keep what they bought earn you credit worth a month of Champion.
Before launch. If three people join the waitlist through your personal link and confirm their email address by 30 November 2026, you get one month of Champion free from launch day. They have to be other people, each with their own address.
Creator codes. A creator's code takes 10% off the first payment for a Champion plan or a session. It comes with the creator's link, or you type it at checkout. One code per purchase, and it does not combine with any other discount; credit on your account (section 03) still comes off. Creators who earn a commission do so under a separate written agreement with us.
Your own link, from launch. Every account gets a personal link and code. The person you refer gets 10% off their first purchase. Once they have paid and 14 days have passed without a refund, they count towards your reward: every three people who count earn you credit worth one month of Champion - $9, or 39 złoty in Poland - for 12 months. On a monthly or annual plan paid by card it comes off your next payment by itself; otherwise it waits on your account for a Champion plan or a session (section 03). At most four rewards in any twelve months; people who count beyond that wait for the next free slot.
What does not count. You cannot refer yourself. The same Discord account, the same PC on a licence or the same payment card counts as you. Posting your link where it is not welcome, sending it to people who did not ask, or advertising under our name ends your part in the programme. We may cancel rewards gained that way.
Rewards are not money. A free month or credit cannot be paid out, exchanged for cash or passed to someone else.
11Prospira Points
Points for opening the app each day, to spend on rewards in the app. They are free and have no cash value.
What they are. Signed in to the Prospira Tweaking Utility, you can claim points once a day and earn some for first steps, such as finishing the first setup. A streak of days earns more each day of the week, and a Champion plan earns twice as many. Each full week of a streak also gives a streak freeze, or bonus points if you already hold as many freezes as you can, and a streak of 30 days or more gives a role on our Discord for as long as it lasts. Points are free: they cannot be bought, sold, passed to someone else or paid out, and they have no cash value. They belong to your account only. Points start once the Discord account you sign in with is 30 days old.
What you can spend them on. The Rewards tab in the app lists what points buy, such as days of Champion, a discount, a voucher for a session, a free PC release, priority support or wallpapers, with the price and any limit next to each. We can change the list, the prices and the limits at any time; a reward you have already redeemed keeps the terms it had. Days of Champion from points never touch a plan you pay for, and they end by themselves. A discount from points applies at checkout and does not combine with a code, but credit on your account (section 03) still comes off. A reward bought with points costs you no money, so the right of withdrawal in section 04 does not apply to it.
When points run out. Points expire after 12 months without any activity on the account, and deleting your account deletes them. They can only be claimed in the app on the PC your licence is on, once a day for that PC. Collecting on several accounts from one PC, faking a PC or a time zone, or any other way of collecting we did not intend ends your part, and we may remove points and rewards gained that way.
If the programme ends. We may end Prospira Points with 30 days' notice in the app; points not spent by then expire. There are no prize draws or lotteries.
12When something goes wrong
We put right what our work broke and answer for the app as the law requires - but not for a change you applied after the app warned you.
If a change we made in a session causes a problem, tell us and we fix it - that is what the follow-up window is for. If the app or a paid feature does not work as described, you have the rights Polish law gives consumers for digital content and services: to have it put right, to a price reduction, or to end the contract. Section 14 says how to complain.
Beyond that, and where the law allows it, our liability is limited to what you paid us, in the twelve months before the problem, for the thing that went wrong - for the free Entry tier that is nothing. We are not liable for data you did not back up, for hardware that was already failing, for the behaviour of software we did not write or install, for a game account restricted by its publisher, for a change you applied after the app warned it could not be undone, or for losses we could not reasonably have foreseen.
None of this limits rights you have by law as a consumer, and nothing here excludes liability for death, personal injury, or anything caused deliberately or by gross negligence - those cannot be signed away and we are not trying to.
13Changes to these terms
They change sometimes, and the date at the top of this page tells you when.
A change applies from the day it is published. It does not reach backwards into a purchase you have already made - the terms that applied when you bought are the terms that govern it. For a subscription, a change applies from your next renewal, and if you do not accept it you can cancel before then. A Champion Lifetime licence and Champion for 3 months have no renewal at which to accept a change, so the terms they were bought under keep governing them.
When these terms or the Privacy Policy change in a way that matters for the app, the app shows you the new version and asks you to accept it before you carry on, and we keep a record of which version you accepted and when.
14Law, and where to complain
Polish law applies, we answer a complaint within 14 days, and complaining costs you nothing.
These terms are governed by Polish law. If you are a consumer resident elsewhere in the EU, that choice does not take away the protections your own country gives you that cannot be contracted out of.
Complaints. Write to contact@prospiratweaks.com, or to the address in section 01, and say what is wrong and what you would like done. We answer within 14 days, and if you are a consumer and we do not answer within that time, your complaint is treated as accepted.
Talk to us first - most things are settled in a ticket. If that fails, and you are in Poland, you can go to a municipal or district consumer ombudsman (miejski lub powiatowy rzecznik konsumentów) or the Office of Competition and Consumer Protection (UOKiK). Both are free.
You will still find other sites pointing consumers at the EU online dispute resolution platform. It closed on 20 July 2025 under Regulation (EU) 2024/3228, so there is nothing there to file with - the two Polish routes above are the working ones.
