The one-sentence version
We store what it takes to bill your plan and sign you in: your email address, identifiers from Square, and records of your plan and your license. We do not collect a device ID for your computer. We do not track your browsing, and we do not look at your other online accounts.
What the browser extension collects
Nothing that leaves your browser. All scam detection runs locally on the page you’re looking at. The URL of the page, its contents, the sites you visit, your searches, your logins — none of that leaves your device.
The extension makes three kinds of outbound network request, all to shield.fasttechpc.com and nowhere else:
- Every 6 hours, it downloads a signed JSON list of known-bad domains so it can flag them.
- At the same time, it downloads a signed list of revoked licenses.
- When you turn protection on, and only then, the activation screen sends us the email address you type into it, so we can find your plan and send you a sign-in link.
The first two are identical for every customer and contain nothing about you. The third sends your email address — no page, no browsing data — and it happens only once, when you press the button yourself to turn protection on. Like any request to any website, all three carry your device’s IP address and basic browser information, the way a phone call carries caller ID. We log the IP address from the third request, the activation request, only — the same way, and for the same reason, we log it for a sign-in request from the portal (see below): only to stop the sign-in system from being hammered with requests. We don’t log the IP address from the first two, routine, requests, and we don’t use the logged activation IP for anything beyond that rate limit. Activation itself happens once; after that, the extension keeps making the same two unlogged, no-PII refresh requests it always did, and there is no activation request left to send.
We previously described this as two requests and said none of them contained anything about you. That was wrong — the activation step was overlooked when that sentence was written. Corrected 2026-08-06.
What we store on our servers
When you start a FastTech Shield plan, the payment runs through Square. Our system records it in our database (Supabase, US region) — your account, your plan, one entry per computer (seat) you bought, and a license for each one. Renewing, adding a seat, or cancelling adds to or updates these same records. Here is everything that can be stored:
- Your email address and an internal account ID
- Your Square customer ID and payment ID(s)
- Your subscription ID, the plan you bought, and an ID for each computer (seat) on it
- The license claims for each seat — a license ID, issue date, and expiry date — which we use to re-sign a fresh copy of the license on demand; we do not keep the signed license itself
- Your billing period end date, and whether the plan, a seat, or a license is active, cancelled, or revoked
- A short record of each sign-in request and renewal reminder we send you
- The IP address behind a sign-in or activation request, to enforce the rate limits described below
We use this to (a) activate your protection on your machines, (b) send you a sign-in link when you ask for one, (c) show you your plan and seat status in the portal, (d) warn you before a seat expires, and (e) revoke a license if you cancel or a payment is refunded. We don’t use it for anything beyond running your plan — no advertising, no profiling, no resale.
Sign-in links expire 15 minutes after they are sent, and can be used more than once inside that window (so an email scanner or a double-click cannot lock you out). For each one we store a short record — a random ID, your email address, the expiry time, and when it was first used. We also log the IP address behind every sign-in or activation request (see above), only to stop someone from hammering the sign-in form; it is not linked to your browsing. We don’t yet have an automatic process that clears out old entries, so today those IP records are kept indefinitely.
This section previously described a smaller, older version of what we store, from before FastTech Shield sold multi-seat and multi-device plans. It now lists everything the current system can store. Corrected 2026-08-19. It also said, incorrectly, that we collect a device ID once a seat is activated, and separately said the IP address on an activation request is not logged when it is. Neither was right: we do not collect a device ID, and the IP address is logged as described above. Both fixed 2026-08-20.
What we DO NOT do
Beyond the handful of companies below that help us run Shield — payments, hosting, and email — we do not:
- Send marketing emails without your explicit consent
- Sell, rent, or license your data to anyone
- Share your data for advertising, or with data brokers
- Track your browsing history or the pages you visit
- Collect a device ID for your computer — a seat is a billing count of computers, not something the software tracks by device today
- Watch your bank, email, passwords, or other accounts
- Have any human at FastTech looking at what you do online
Third parties we work with
Square
Handles all payment processing. We never see your card number.
Microsoft 365
Carries our email. Sign-in links and receipts are sent from support@fasttechpc.com through Microsoft Graph — the same mailbox a FastTech technician would write to you from.
Vercel
Hosts our website and the webhook endpoint.
Supabase
Hosts the database described above — your account, plan, and license records.
Your rights
You can email support@fasttechpc.com at any time to:
- Get a copy of everything we store about you
- Correct it if it’s wrong
- Delete it (this cancels any active license)
We are a small local shop, not a company with a dedicated privacy department — but a real person reads every request, and we respond as quickly as we can. If you are covered by a law like California’s CCPA or Europe’s GDPR, those rights apply to you, and we will honor a request made under them the same way.
Data breach
If our database is ever breached, we will notify affected customers by email as soon as we reasonably can after confirming it. What could be exposed: the account, plan, and license information listed above — your email address, Square identifiers, plan and seat details, and the IP addresses logged for rate limiting. Not passwords (we don’t store any — signing in uses an emailed link, not a password). Not your extension’s activity (the extension doesn’t send us any).
