The LogBench app collects nothing. It never connects to the internet.

This page covers three things: the app, this website, and buying. They are different, so we describe each one on its own.

1. The app

LogBench is one HTML file. It runs inside your web browser, on your own computer. It has no account, no sign-in, and no server.

• No network connections. The app does not send or receive anything. You can check this: turn off your internet and use it. It works the same.
• Your trade file stays on your computer. The app reads it on your machine. It is never uploaded.
• We never see your trades. We have no way to.

What the app saves on your computer. The app saves a few things in your browser's own storage, so it works better next time. This storage is on your computer only.

• How you matched the columns in your file, so you do not have to do it again.
• Your settings, such as what one point is worth for each market.
• Your trades — only if you turn on "Keep my trades saved on this computer." This is off until you turn it on.
• A few simple counters, such as how many times you opened each tab. You can see every one of them in Settings & Diagnostics. They are never sent anywhere.

To remove all of it, open Settings & Diagnostics and click Delete everything this app has stored. One small yes/no note stays, so the welcome tour does not start again. Clearing your browser's site data also removes everything.

2. Feedback (optional)

The app has a Share anonymous feedback button. It opens a form in your browser, hosted by Tally (tally.so). The form does not ask for your name or email. Anything you type there goes to Tally and then to us, and Tally's own privacy policy applies to it.

The Copy usage snapshot button copies the counters above to your clipboard. Nothing is sent. If you choose to paste the snapshot into the form, we see those counts. They contain no trades and nothing that identifies you.

3. This website

This website counts visits with a cookie-free visitor counter. It uses no cookies, no ads, and no tracking across other sites. It does not record who you are. We use it only to know how many people find the site.

Like every website, the company that hosts these pages may briefly keep basic technical records, such as your IP address, to deliver the page and to stop attacks. We do not use these records to identify you.

4. Buying

Your purchase is handled by Lemon Squeezy, our reseller. They take your payment, your billing details, and any sales tax. Their privacy policy applies to that data. We never see your card number.

They share with us what we need to support your order: your name, email address, what you bought, and your country. We use this only to deliver your purchase, answer you, and handle refunds.

5. Email

If you email us, we have your email address and your message. We use them only to reply to you. We do not add you to a mailing list, and we never sell or share your details.

Your choices

You can ask us to show you or delete any details we hold about you. Email LogBench@proton.me. For payment records, we pass your request to Lemon Squeezy. They may need to keep some records by law, for tax.

Changes

If this policy changes, we update this page and the date at the top.
