The fine print, in plain sight.
MEGA’s licence agreement, our refund policy, exactly what MEGA sends over the internet, and what we don’t promise. Last updated 11 October 2026.
MEGA End User License Agreement
Version 1.0. This is the same agreement the MEGA installer asks you to accept.
IMPORTANT — READ CAREFULLY. This is a legal agreement between you and the MEGA vendor (“the Licensor”). By installing or using MEGA (“the Software”) you agree to these terms.
1. Paid license
The Software is a commercial product — licensed, not sold. Upon purchase of a valid license from the Licensor’s official website, you are granted a non-exclusive, non-transferable license to install and use the Software on the number of devices covered by the plan you purchased, for as long as your license remains valid. Using the Software without a valid purchased license is not permitted.
2. License keys & activation
Your license may be tied to a license key or account. You are responsible for keeping it confidential. Sharing, publishing, distributing or reselling license keys is prohibited and may result in your license being revoked without refund.
3. Restrictions
You may NOT: copy, redistribute, resell, rent, lease, sublicense, share or give away the Software or your license; remove or alter any branding, copyright or notices; reverse-engineer, decompile or disassemble the Software except where that restriction is prohibited by law; or use it to build or assist a competing product.
4. Ownership
The Software is protected by copyright and other laws. The Licensor retains all right, title and interest in and to the Software. No rights are granted except those expressly stated in this Agreement.
5. What MEGA does
The Software reads system information and performance counters to display live statistics, analyses your drives to find removable junk, and can apply optimizations that modify Windows settings and the registry. Every change is shown to you first and requires your explicit confirmation, and the Software never deletes files without listing them. Some optimizations require Administrator elevation, which Windows requests only for those actions; you may decline.
6. Privacy
The Software installs into your user profile. It does not sell your personal data. (The full privacy policy is below.)
7. Refunds
Purchases are subject to the refund policy published on the Licensor’s website at the time of purchase. (See the refund policy below.)
8. No warranty
THE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. YOU USE IT AT YOUR OWN RISK. System optimizations carry inherent risk; you are advised to create a restore point before applying changes.
9. Limitation of liability
To the maximum extent permitted by law, the Licensor shall not be liable for any damages arising from the use of, or inability to use, the Software, including data loss or system instability. Total liability shall not exceed the amount you paid for your license.
10. Termination
This license terminates automatically if you breach these terms. On termination you must stop using and uninstall the Software.
11. Acceptance
By checking the box in the installer and continuing, you confirm you have read and agree to this Agreement.
Refund policy
Applies to every Astrix product bought on this website: MEGA, Astrix Optimizer Plus and Pro, and any other Astrix licence.
Within 24 hours: full refund
If you ask within 24 hours of your purchase (the time on your Stripe receipt), you get a full refund. Message us privately on the Astrix Discord with the email address you paid with. The money goes back to your original payment method through Stripe; your bank may take a few business days to show it.
After 24 hours: no refunds
Purchases are final once 24 hours have passed.
What happens to the licence
A refunded licence key is deactivated, so the product goes back to its free or locked state on every PC that used it.
Nothing in this policy takes away any rights you have under the consumer law where you live.
Referral program terms
For MEGA and Astrix Ultimate owners who share their invite link or code (see Earn money). By sharing your link or code you agree to these terms.
1. Who can take part
- You must own an active MEGA or Astrix Ultimate licence bought from us. Each licence gets one invite code, and each person may have only one.
- To receive payouts you must be at least 18, or have a parent or guardian's permission.
- We can decline or remove anyone from the program.
2. What you earn
- You earn $20 (USD) for each qualifying Astrix Ultimate purchase and $3 (USD) for each qualifying MEGA purchase made through your invite link or with your code entered as a promotion code at checkout. The buyer gets 15% off Ultimate (your code followed by U) or 10% off MEGA (your code).
- Purchases of Astrix Optimizer Plus or Pro (including upgrades) don't qualify.
- A purchase is credited to the code used at its checkout. Only one code can be used per purchase, and codes can't be added after a purchase is made.
3. When a purchase qualifies
A purchase only counts when all of these are true:
- it was made by a genuine buyer with their own payment method;
- the 24-hour refund window has passed and it wasn't refunded, charged back or disputed;
- it wasn't made by you or for you, including through other accounts, other email addresses, someone buying on your behalf, or a licence activated on your own PC;
- it didn't come from any promotion method that's not allowed (section 4).
4. Promotion that's not allowed
- Posting your link or code on coupon, deal, voucher or cashback sites or browser extensions (for example Honey, RetailMeNot or Slickdeals), or in deal threads.
- Paid ads that use or bid on the names Astrix or MEGA.
- Spam: unsolicited DMs, emails, mass comments or posts.
- Misleading claims, such as fake discounts, guaranteed FPS or performance numbers, or pretending to be Astrix staff or an official account.
- Paying people to buy, or offering buyers cash back or a share of your reward.
- Fake accounts, fake purchases, or anything automated.
Sales that come from any of these don't count, and doing them can lose you your code and any unpaid earnings.
5. Reversals and clawbacks
- If a purchase is refunded, charged back or disputed, its reward is cancelled, even after it was confirmed.
- If that reward was already paid, it's deducted from your future earnings, and we may ask you to return it.
6. Payouts
- Payouts start at a $9 minimum confirmed balance (for example one qualifying Ultimate purchase, or three MEGA purchases).
- Ask for a payout on our Discord with your code. We review every request before paying, may ask for information to verify your sales, and may hold a payout while a sale is under review.
- We pay by hand, by PayPal, Cash App or Venmo (your choice), within 7 days of approving a request. Every sale and payout is recorded and shown to you on the Earn money page.
- Any fees on your side, and any taxes on what you earn, are your responsibility.
7. Enforcement
- If these terms are broken, we can switch off your code, reverse sales, and withhold or cancel unpaid earnings.
- Our decision on whether a purchase qualifies is final.
8. Changes
We can change or end the referral program at any time. Earnings that were confirmed before a change will still be paid, as long as they meet these terms.
Privacy policy
Short version: no telemetry, no ads, no trackers, no selling data. MEGA goes online only for the things listed here.
What stays on your PC
MEGA’s settings, licence file and sign-in data live in %APPDATA%\MEGA on your computer. The hardware readings, drive scans, process lists and tweak states you see in the app are worked out locally and are never uploaded.
Every connection MEGA makes
| When | What is sent, and to whom |
|---|---|
| Activating a licence | Your licence key, your Windows machine ID (the MachineGuid Windows assigns to each install) and the app name, sent once to our licence server (hosted on Netlify). The machine ID is how a key is tied to the PC it's activated on (one PC per key, or up to 3 for Astrix Ultimate). |
| Checking for updates | MEGA downloads a small version file from GitHub, where MEGA’s releases are hosted. Nothing about you is sent beyond what any download reveals (your IP address, to GitHub). |
| Google sign-in (optional) | If you choose to sign in, Google shares your name, email address and profile picture with MEGA (scopes: openid email profile). The sign-in tokens are kept on your PC so you stay signed in. |
| Cloud backup (optional) | Only when you press back up: your MEGA settings file is stored on our server under your Google account, together with your email address and the time of the backup. Restore downloads it again. |
| Speed test (when you run it) | Test data is downloaded from and uploaded to Cloudflare’s public speed-test service. Ping and DNS tests send small test requests to the game and DNS servers being measured. |
| Links you click | Driver, support and store links open in your browser; those sites have their own privacy policies. |
What we store about you
- When you buy MEGA: payment is handled by Stripe — we never see your card. Stripe gives us your email address, which we store with your licence key and use to email you that key (sent through the Resend email service).
- Your licence record: the key, its plan, your purchase email, the date it was issued, the machine IDs it is activated on, and which Astrix apps have used it with first/last-used times and a use count.
- Cloud backup (only if you use it): your MEGA settings, your email address and the backup time.
What we don’t do
- No analytics, telemetry, crash reporting, ads or third-party trackers — in MEGA or on this website.
- We don’t sell, rent or share your data with anyone for marketing.
- This website counts clicks on the download button (a single running number, nothing about who clicked). Like any web host, Netlify processes your IP address to serve the pages.
Your choices
- Sign-in and cloud backup are optional; MEGA works fully without them. Signing out in MEGA deletes the saved Google tokens from your PC.
- When you uninstall MEGA you choose whether to also delete your MEGA data and licence from this PC.
- To ask what we hold about you, or to have your backup or licence record deleted, contact us (see Contact).
Disclaimer
What MEGA is, and what it isn’t.
No performance guarantees
MEGA’s tweaks change real Windows settings, and how much they help depends on your hardware, drivers, games and what else is running. We don’t promise any FPS, ping or speed improvement, and we never publish made-up numbers. Tweaks can be switched back off from inside MEGA, and we recommend creating a System Restore point first (MEGA can make one for you).
Games and anti-cheat
MEGA doesn’t inject into, modify or read the memory of any game. Its Fortnite settings feature edits Fortnite’s own settings file, only while Fortnite is closed, and saves a backup first. You are still responsible for following each game’s terms of service.
The gaming guide
The gaming guide, in MEGA and on this site, is general information, not professional advice. Check before changing BIOS, overclocking or editing the registry by hand.

We are not affiliated with, endorsed by or sponsored by Microsoft, Epic Games, NVIDIA, AMD, Intel, Valve, Google, Discord or any other company named in our apps or on this site. Windows, Fortnite and all other product names, logos and trademarks belong to their respective owners and are used only to describe compatibility.
