Privacy Policy — Trading Strategy Optimizer for TradingView
Last updated: 8 September 2026
The short version
This extension does not collect, sell, or share your data. There is no analytics, no tracking, and no account. It makes exactly one kind of network request, and only if you buy a licence: it asks Gumroad whether your licence key is valid.
What it stores, and where
Everything it saves is written to your browser's local storage on your own machine, and stays there:
- Parameter setups — the ranges, steps and priorities you configure for each strategy, so they are still there next time you open the panel.
- Optimizer preferences — your chosen metric, search method, filters and cycle count.
- Licence key — if you have purchased Pro, the key you entered, along with the details Gumroad returned about that purchase (the email address on the order, whether it is monthly or yearly, and how many times the key has been activated) and the date it was last confirmed.
- A random installation id — a generated identifier with no connection to you or your machine, used only to tell one browser from another.
You can erase all of it at any time by removing the extension, or by clearing site data for tradingview.com in Chrome's settings.
What it reads
While you are on a tradingview.com/chart/ page, the extension reads
the Pine strategy you have applied to that chart — its input parameters and the
results its backtest produces — and writes new parameter values back to it while an
optimization is running. This happens entirely inside your browser tab. None of it
is sent anywhere.
It does not read any other page, any other tab, your browsing history, your TradingView account details, your credentials, or anything else on the site.
Network requests
Free plan: none. If you never enter a licence key, the extension never contacts anything.
Pro plan: licence checks only. When you activate a licence, and
roughly twice a day afterwards while Chrome is running, the extension sends a
request to api.gumroad.com — the licensing service of the payment
provider — containing:
- your licence key,
- the product id of this extension,
- a flag saying whether this check should count as a new activation (true only the first time you enter a key on a given browser).
That is the whole payload. No chart data, no strategy, no parameters, no results, no browsing information, and nothing identifying you beyond the key you chose to enter. Gumroad replies with the status of your purchase, and that reply is what decides whether Pro is on. Gumroad's handling of the request is covered by their own privacy policy.
If the check cannot be made — you are offline, or something on your network blocks the domain — Pro keeps working for 14 days on the last confirmed answer, then pauses until it can be confirmed again.
Pressing "Get Pro" opens the purchase page in a new tab. That is the only other outbound action, and it only happens when you click it.
Files you export
CSV and JSON exports are generated in your browser and saved by Chrome's normal download mechanism. They are never uploaded.
Changes
If this policy changes, the updated version will be published here with a new date, and any change that affects what data is handled will be called out in the extension's release notes.
