Privacy Policy

Effective: 11/13/2026

Boost Opti is a Windows app that checks the health of a PC and applies fixes you choose. This policy explains what information leaves your PC, what we keep, and what your choices are.

Who we are. Boost Opti is provided by Chase Nielsen, United States ("we", "us"). We are responsible for the information described here (in legal terms, its controller). You can reach us at support@boostopti.com.

The short version

What stays on your PC

The app keeps its own records in your Windows user profile (%APPDATA%\Boost Opti): your settings, the results of your last check, a history of the changes it made so they can be undone, periodic lists of installed programs and startup items (for the "what changed" feature), and disk-space history (for trends). None of this is sent to us. Uninstalling the app and deleting that folder removes it.

If you export a health report, it is saved as a file where you choose. It contains your PC's name, its hardware and the check's findings. Who sees it is up to you.

Checking for a newer version

About once a day, the app asks our server whether a newer version of Boost Opti is available. It is the same question from every copy of the app: it contains no licence key, no hardware identifiers, no name and nothing about your PC or how you use it. Like any internet request, it reaches our server from your IP address. Our licence service uses the address only to limit abuse and does not record it for this request; our hosting provider may keep its own short-lived request logs, as any web host does. If a newer version exists, the app tells you. It does not download or install anything by itself.

You can switch this off in the app under Settings, Look for new versions. Checking by hand with the button beside it sends the same question once.

What is sent when you subscribe

When you buy. Payment is handled by Lemon Squeezy, our reseller and merchant of record. They collect your payment details, billing address and tax information under their own privacy policy, which is shown at checkout. We never see your card details. They pass us your email address, the name you gave, the order and subscription numbers, the product you bought, and your subscription's status and renewal or end dates.

When the app checks your licence (when you activate, and about every 12 hours while the app is running), it sends our licence server:

WhatWhy
Your licence keyTo find your subscription.
Four scrambled hardware identifiers, made from your Windows installation ID, motherboard ID, system drive serial number and processor IDTo recognise the same PC next time, so that a subscription works on the number of PCs it covers. The app scrambles these with a one-way function before sending. We never receive the serial numbers themselves. They are still stable identifiers for your PC, so we treat them as personal information.
The model names of your processor, graphics card, motherboard and system drive, the amount of memory, and your Windows edition and buildSo that, if you contact support about which PC your subscription is on, we can tell your PCs apart.
Your PC's name (sent when you activate)The same reason. If another PC tries to use your key, it is shown only a shortened form of the name.
The app's versionFor support and compatibility.
Your IP addressIt arrives with any internet request. We use it to limit abuse, and keep it in the activity record described below.

The network test, when you run it, measures your connection by pinging your own router, 1.1.1.1 (Cloudflare) and 8.8.8.8 (Google), and by timing how long your own DNS server and those two take to look up www.microsoft.com. Those services see your IP address and that one lookup, as they would for any use of the internet. Nothing about the result is sent to us.

Nothing else. The app does not send us your files, file names, browsing history, list of installed programs, or anything you type other than your licence key. It does not send us the results of your checks either, unless you publish them yourself as described next.

If you publish a certificate or a care link

These are optional features for subscribers. Each one asks you first, in a Windows prompt, and sends nothing if you say no.

What is sent. For each check the app ran: which check it was, how it came out, and its one-line summary (for example "C: is almost full: 96 GB free"). With that go the time of the check, the app's version, and your licence key and scrambled hardware identifiers, so that our server knows which subscription and which of its PCs is asking. For a care link, also the name you choose to give the PC. Not sent: your name, the PC's name, your files, or any detail beyond those one-line summaries.

What the page shows. Those results, a score worked out from them, and the model names of the PC's main parts and its Windows version, which we already hold from your subscription. It does not show your name, your email address, your licence key, the PC's name or its hardware identifiers.

Who can see it. Anyone who has the page's address. The address contains a long random code and is not listed anywhere or offered to search engines, but anyone you give it to can pass it on, so share it as you would share the results themselves.

How long it stays. A certificate is removed 30 days after you make it. A care link is removed when you stop it, when the PC is taken off your subscription, or 30 days after the PC last reported. You can remove either at any time in the app (the Remove button beside the certificate; Stop in Settings), and we will remove one for you if you ask.

Our activity record notes that a page was published and from which PC, with the IP address the request came from. It does not record what the page says.

What we use it for

PurposeOur legal ground, where the GDPR or UK GDPR applies
Providing the subscription you bought: confirming it is active, tying it to your PC, letting you move itPerforming our contract with you
Preventing a key from being shared or resold, stopping payment fraud, and blocking hardware used for eitherOur legitimate interest in protecting the service
Publishing a certificate or a care link when you ask for onePerforming our contract with you; it happens only at your request, and you can withdraw it at any time by removing the page
Answering support requestsPerforming our contract with you, and our legitimate interest in supporting customers
Keeping records the law requiresLegal obligation

We do not use your information for advertising or profiling. A licence can be refused automatically, for example when it is already in use on another PC. If you think a refusal was wrong, contact us and a person will look at it.

How long we keep it

InformationKept for
The activity record: each activation, move, refusal and administrative action, with the IP address it came from180 days, then deleted automatically
A PC's record on your subscriptionIts IP address is erased 180 days after that PC last checked in. The whole record is deleted after one year without a check-in, or at once when you remove the PC, move the subscription, or we reset it for you
Your licence record: email, name, order and subscription numbers, statusWhile your subscription is active and for up to 24 months after it ends, then deleted. You can ask us to delete it sooner
A certificate you published30 days, or until you remove it
A care link you switched onUntil you stop it, the PC leaves your subscription, or 30 days after the PC last reported
A block on hardware used for fraud or abuse: the scrambled identifiers onlyUntil the block is lifted

Lemon Squeezy keeps purchase and tax records for as long as their own legal obligations require.

Who else handles it

We do not give your information to anyone else, except where the law requires it or where it is needed to establish or defend a legal claim.

Where it is stored. Our licence server may be in a different country from yours. Where information about people in the European Economic Area, the United Kingdom or Switzerland is stored or handled outside those places, we rely on the safeguards the law provides for such transfers, such as the standard contractual clauses offered by our hosting provider.

Security

Licence keys are stored only in scrambled (hashed) form. Hardware identifiers reach us already scrambled. Connections to the licence server are encrypted. Access to customer records is limited to the people who run the service. No system is perfectly secure; if a breach affects you, we will tell you as the law requires.

Your choices and rights

We reply to requests within one month.

Children

Boost Opti is not directed at children. Subscriptions may only be bought by adults, and we do not knowingly collect information from anyone under 16. If you believe a child has given us information, contact us and we will delete it.

Changes to this policy

If we change what the app collects or how we use it, we will update this page and its date before the change takes effect, and describe the change in the app's release notes.
