Privacy Policy

Eflatun Trader — Chrome browser extension

Last updated: 6 September 2026 · Version 0.13.0

In short This extension has no server. No personal data is collected, transmitted or stored. Everything the extension remembers is kept by Chrome on your own computer. Nothing is ever sent to the developer.

Data we collect

None. There is no backend, no account system and no database behind this extension. It collects no usage statistics, no analytics, no crash reports and no advertising identifiers. Your personal data is not sold, rented or shared — none of which is possible, because none is collected.

What is stored on your computer

The following is kept in Chrome's local extension storage (chrome.storage.local). It is readable only by this extension, only on this browser profile, and is never uploaded anywhere. Removing the extension deletes all of it.

RecordContents
SettingsPanel preferences, indicator setup, your watchlist and — if you entered them — the Telegram bot token and the Reddit application ID.
AlarmsYour alarm definitions and their state.
NotesNotes you write, with their colour, text size and the symbol each is attached to.
Social baselinePer-symbol mention counts from past scans. Numbers only; no post text is stored.
Report stateTimestamps of the last automatic Telegram report (when it was due, tried and last succeeded) and the reason if the last attempt failed. Timestamps and a short error string only.

The extension's own Privacy & connections page shows the live count of these records and lets you erase all of them with one button.

Servers the extension connects to

The extension fetches market data directly from the public sources below. These requests carry only a symbol name or a search term; nothing that identifies you is attached. There is no intermediary server.

HostPurposeWhat is sent
tradingview.comReading the chart page you already have openNothing — read only
api.binance.comCrypto candles and the list of tradable pairsSymbol name
query1/query2.finance.yahoo.comCandles for shares, indices and FX, plus news headlinesSymbol name or search term
api.telegram.orgDelivering alarm and report messages to your own botYour bot token, your chat ID and the message text

The following are optional. No request reaches them until you enable the relevant feature and approve Chrome's permission prompt:

HostPurposeWhat is sent

An important note about Telegram

If you turn on Telegram notifications, this is the one place your own content leaves the device: the alarm text and the daily report contain the symbols on your watchlist, their prices and your fired alarms. Those messages travel through Telegram and arrive at the bot you created, in the chat you configured. The developer has no access to them. For Telegram's own terms see telegram.org/privacy.

Tokens and keys

The Telegram bot token and the Reddit application ID are stored only on your computer and are sent only to the corresponding service. If you export a backup file, the Telegram token is written into it — treat that file as sensitive. The Reddit ID is deliberately left out of backups.

The extension never asks for an exchange API key, cannot place orders, cannot move funds and does not sign in to any account. It only reads public market data.

Cookies and tracking

The extension sets no cookies, places no tracking pixels, performs no fingerprinting and does not read your browsing history. On the TradingView page the only thing it does is read the data stream that page is already receiving; it opens no connection of its own there and sends nothing out.

Children's privacy

The extension is not directed at users under 13 and collects no personal data from anyone, including age information.

Erasing your data

The “Erase all local data” button on the extension's Privacy & connections page clears everything. Removing the extension from chrome://extensions has the same effect. There is no copy held by the developer, so no separate deletion request is needed.

Changes

If this policy changes, the date above is updated. Any material change to how data is handled will be stated in the release notes of the new version.
