Delta Bridge is made of three parts: a Chrome extension, a small app that runs on your Windows PC, and add-ons for your trading platform. This page explains what each part handles. The short version: Delta Bridge reads one thing - the replay date and time of the backtest you're looking at - and that never leaves your computer.

The Chrome extension

• What it reads: on backtesting sites you use it with (TradeZella, TradingView, FX Replay, and any other site you add yourself), it reads the date and time of the replay - the time of the candle you're on - and the replay timeframe. It does not read your trades, account details, balances, notes, passwords or anything else on the page.
• Where it goes: only to the Delta Bridge app on your own computer, at 127.0.0.1 (your PC talking to itself). It is never sent to us or to anyone else.
• What it stores: your settings, such as which sites to watch and your timeframe choice, in Chrome's local storage on your computer.
• Other sites: the extension only runs on the backtesting sites listed above. It runs on another site only if you add that site from the extension's popup, and Chrome asks for your permission first.
• No analytics, tracking, advertising or cookies.

The Delta Bridge app and platform add-ons

The app receives the replay time from the extension and moves your trading platform's replay to the same moment, through the add-on inside the platform. Everything happens on your computer. Its settings and a log of recent sync actions are stored in %APPDATA%\DeltaBridge. The add-ons only control replay; they never place orders and never access your trading accounts.

Free trial and license

So each PC gets the free trial once, the app sends deltabridge.app an anonymous code made by scrambling (hashing) your Windows installation's ID. It can't be turned back into that ID and contains no name or email; we store only that code and the date its trial started. If you buy a license, purchases are handled by our reseller, Lemon Squeezy, and the app checks your license key with Lemon Squeezy about once a day, sending the key and your PC's name.

This website and the waitlist

If you join the waitlist, we collect your email address and, if you choose it, your order flow platform. We use them only to send you Delta Bridge updates and early-access invitations. The list is stored with our email provider, Loops, which processes it on our behalf. Every email has an unsubscribe link, and you can ask us to delete your details at any time.

Selling or sharing data

We don't sell or rent your data, and we don't share it except with the email provider above to run the waitlist.
