Privacy Policy

Effective Date: October 30, 2025

1. Overview

The “Binance – Crypto Tools & Alert” Chrome extension is a read-only dashboard for Binance Spot market data. It shows live Price, RSI(14), 24h%, and an EMA Trend (20/50/200), supports manual and automatic alerts, and includes several bundled tools. The extension is independent and not affiliated with Binance; it never requests API keys, logins, or wallet access.

What you can do with the extension

• Manual Price Alerts — cross-based triggers (Above/Below) with hysteresis, minimum repeat, optional one-shot and mute; shows a browser notification on trigger.
• Auto Alerts — locally evaluated RSI, EMA cross (20×50/200), Price×EMA (20/50/200), Volume Spike (open-bar gates: progress/body/persist) and 24h% change; global cooldown; optional closed-bar mode; per-indicator timeframe lists; fine EMA filters (separation/hold/full).
• Market Pulse — context tiles (Fear & Greed, BTC mempool/fees, BTC/ETH funding & basis, market breadth, total market cap) from public read-only APIs, cached briefly for performance.
• Global Ticker — an optional TradingView ticker-tape widget (iframe) for macro indices/FX/commodities (e.g., DXY, US 2Y/10Y, VIX, S&P 500, WTI, Gold).
• Built-in Tools (static HTML packaged with the extension): Order Book + Trades, Futures Sentiment, Taker Flow, EMA/RSI/MACD/ATR Monitor, Pattern Scanner, US Macro/Crypto Risk. These pages run locally; they are not remote web apps.

All indicator math and alert evaluation happens locally. The extension does not collect personal data or browsing history and does not transmit identifiers.

2. Permissions Used

• storage — Saves your configuration and small caches:
  • Live Prices preferences (selected Spot symbols/timeframes; column toggles for EMA 20/50/200, MACD, ATR%, BB width, 24h volume; row grouping/ordering; compact view; active tab; hidden toolbars).
  • Manual Alerts (symbol, condition, target, enabled, one-shot, mute) and behavior (hysteresis %, minRepeatMs, cooldown, alert style, hide alerts in popup).
  • Auto Alerts settings (RSI thresholds, EMA mode/filters, Price×EMA/Volume Spike parameters, closed-bar mode, per-indicator TF lists; 24h% +/- defaults).
  • Short-lived caches: Market Pulse snapshots and recent klines used for local indicator math.
• notifications — Displays a system notification only when a manual or auto alert fires (symbol + event context; no personal data). Actions may include “Open on Binance” or “Disable alert”.
• alarms — Periodic wake-ups for the service worker to refresh public data and evaluate alerts while the popup is closed. Not used for tracking or profiling.
• offscreen — Creates an audio-only offscreen page to play alert sounds reliably (Chrome autoplay policy). No mic/cam; no recording; destroyed after use.
• Host permissions (read-only) — Public REST/WS endpoints only:
  • https://api.binance.com/* (Spot) and https://fapi.binance.com/* (public Futures endpoints for funding & basis in Market Pulse).
  • https://stream.binance.com/* and https://fstream.binance.com/* for real-time WebSocket streams (prices/klines) used by the background/offscreen components.
  • https://api.coingecko.com/*, https://api.alternative.me/*, https://mempool.space/* — public index/chain metrics for Market Pulse.

2.1 TradingView widget (iframe)

The “Global Ticker” block embeds an official TradingView price widget via <iframe> from https://s.tradingview.com/. The extension does not programmatically call TradingView APIs, does not inject user identifiers, and does not read cookies or network traffic inside the iframe. TradingView may process data under its own policy on its domain. You can disable this block anytime in Options.

2.2 Clipboard Use

When you click “Copy address” in the donation dialog, the displayed BNB (BEP-20) address is written to your clipboard. The extension never reads clipboard contents and never writes without your explicit action.

3. Data Storage and Use

• User settings live in Chrome’s storage areas (sync/local). Short-lived caches (Market Pulse snapshots, recent klines, cooldown stamps) are used strictly to render UI and evaluate alerts and expire automatically.
• No personal data is collected, processed, or transmitted. No browsing history, account credentials, wallet keys, or payment data.
• Network use is limited to the public endpoints listed above (HTTPS/WS). No analytics SDKs or tracking pixels are embedded.

4. Binance API & WebSocket Data

• All requests are read-only; no login or API keys; no account endpoints.
• REST: prices/24h/klines/premium index; WS: price/kline streams for near real-time alerts even when the popup is closed.
• Requests carry no personal identifiers; results are processed locally for indicators (RSI/EMA/MACD/ATR) and alert checks.

5. Market Pulse sources

• Fear & Greed — api.alternative.me/fng
• BTC mempool & fees — mempool.space/api/…
• Funding & basis for BTC/ETH — fapi.binance.com/fapi/v1/premiumIndex
• 24h breadth (advancers/decliners by volume) — api.binance.com/api/v3/ticker/24hr
• Global crypto market cap & dominance — api.coingecko.com/api/v3/global

Responses are cached for short periods in Chrome storage to reduce external requests. No personal data is attached to these calls.

6. Auto Alerts (local evaluation)

• RSI thresholds, EMA cross (20×50/200), Price×EMA (20/50/200), Volume Spike (progress/body/persist gates), 24h%.
• Global cooldown; optional closed-bar mode; per-indicator timeframe lists; EMA filter modes (none / separation / separation+hold / full).
• On trigger, a browser notification is displayed; if enabled, a short sound is played via offscreen audio.

7. Built-in Tools (static)

The following tools are packaged as static HTML within the extension and run locally: Order Book + Trades, Futures Sentiment, Taker Flow, EMA/RSI/MACD/ATR Monitor, Pattern Scanner, US Macro/Crypto Risk. They do not fetch or submit personal data.

8. Security & No Tracking

• No telemetry, analytics, or ad SDKs. No fingerprinting.
• No content scripts that read page contents; the extension does not access tabs or history.
• All outbound connections use HTTPS (and WS to Binance official hosts).
• The offscreen document is ephemeral and audio-only.

9. Data Retention & Deletion

• Settings persist until you change or reset them in Options.
• Short-lived caches auto-expire (minutes) or are cleared on reset/uninstall.
• Uninstalling the extension removes its Chrome storage data.

10. Third-Party Services

• Binance public APIs — market/funding data only; see Binance’s terms for their services.
• Coingecko / Alternative.me / Mempool.space — public index feeds for Market Pulse (read-only).
• TradingView — embedded price widget (iframe) for macro assets; no direct API calls by the extension; subject to TradingView’s policy on their domain.
• Donations — optional external links (e.g., PayPal, Binance address); the extension does not collect payment information.

11. Incognito Mode

Behavior and privacy are identical to normal mode; no additional data collection occurs.

12. Children’s Privacy

This extension is not directed to children under 13 and does not knowingly collect information from children.

13. No Financial Advice

All data and signals are informational/educational only and do not constitute investment, financial, or trading advice.

14. Data Practices Summary

• Data collected: None (only local settings/caches in Chrome storage).
• Data shared/sold: None.
• Network calls: Public Binance REST/WS + public index APIs; optional TradingView iframe for display only.
