Privacy Policy

Last Updated: August 6, 2026  ·  Effective Date: January 23, 2026

Introduction

PriceTab ("we", "our", or "the extension") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our Chrome browser extension.

Information We Collect

Data Stored Locally

PriceTab stores the following information locally on your device only:

• Cryptocurrency Preferences: The list of cryptocurrency symbols you select (e.g., BTC, ETH, SOL)
• Coin Order: The order in which you arrange your selected coins
• Widget Settings: Which widgets are enabled and their display order
• UI Preferences: Theme, currency, refresh interval, hidden widget states

This data is stored using the browser's localStorage API and never leaves your device.

Data We Do NOT Collect

• We do NOT collect any personal information
• We do NOT collect your browsing history
• We do NOT track your activity
• We do NOT use cookies for tracking
• We do NOT share any data with third parties
• We do NOT use analytics or telemetry
• We do NOT store data on our servers (we don't have any servers)
• We do NOT sell or monetize user data in any way

Third-Party Services

All APIs used by PriceTab are public — no authentication or accounts required.

Coinbase Public API

• Endpoints: https://www.coinbase.com/api/v2/prices/ and https://api.exchange.coinbase.com/products/…/candles
• Purpose: Real-time cryptocurrency prices, historical charts, and the chart's open/high/low/close/volume readout
• Data Sent: Coin symbol (e.g., "BTC-USD") and time period
• Privacy: Coinbase Privacy Policy

Kraken Public API

• Endpoints: https://api.kraken.com/0/public/OHLC and https://api.kraken.com/0/public/Ticker
• Purpose: Prices and charts for coins Coinbase does not list (currently Monero)
• Data Sent: Coin pair (e.g. "XMRUSD") and interval — no user data
• Privacy: Kraken Privacy Policy

Alternative.me (Fear & Greed Index)

• Endpoint: https://api.alternative.me/fng/
• Purpose: Crypto Fear & Greed Index widget
• Data Sent: No user data — plain GET request

OKX Public API (optional widgets)

• Endpoint: https://www.okx.com/api/v5/public/
• Purpose: Funding rate, Open Interest, and Liquidations widgets
• Data Sent: Coin pair — no user data
• Privacy: OKX Privacy Policy

Bybit Public API (optional widget)

• Endpoint: https://api.bybit.com/v5/market/
• Purpose: Long/Short ratio widget
• Data Sent: Coin symbol — no user data
• Privacy: Bybit Privacy Policy

Coinlore Public API (optional widgets)

• Endpoint: https://api.coinlore.com/api/
• Purpose: Market Overview (market cap, volume, dominance) and Altcoin Season Index widgets
• Data Sent: No user data — plain GET requests
• Privacy: Coinlore

mempool.space API (optional widget)

• Endpoint: https://mempool.space/api/
• Purpose: Bitcoin Halving Countdown (current block height)
• Data Sent: No user data — plain GET request
• Privacy: mempool.space Privacy Policy

Address balance lookup (optional portfolio watching)

• Endpoints: https://mempool.space/api/address/… (BTC balance and transaction history), https://api.blockchair.com/{chain}/dashboards/address/… (ETH, LTC, DOGE, BCH, ZEC balances) and https://ethereum-rpc.publicnode.com (ERC-20 token balances, read from each token's own contract)
• Purpose: If you choose to watch one of your own addresses in the portfolio, its public on-chain balance is read so the holding's amount stays in sync; for BTC the public transfer history is also read to estimate dated purchase lots for the cost-basis view
• Data Sent: Only the address you enter, only to the balance provider for that coin, and only while the portfolio feature is used — PriceTab never sends it anywhere else. This is a read-only lookup of public blockchain data; no keys, no signing, no wallet connection
• Storage: Watched addresses are stored locally in your browser like every other setting and can be removed at any time (⛓ icon on the holding)
• Privacy: mempool.space Privacy Policy, Blockchair Privacy Policy, PublicNode Privacy Policy

News sources (optional ticker row)

• Endpoints: https://api.blockchair.com/news and https://hn.algolia.com/api/v1/search (Hacker News stories)
• Purpose: Crypto news headlines in the optional ticker bar (off by default)
• Data Sent: No user data — plain GET requests
• Outbound links: Clicking a headline opens the news site in a new tab. The link carries no referrer information (rel="noreferrer"), so the site cannot tell the visit came from PriceTab. From that point the news site's own privacy policy applies.
• Privacy: Blockchair Privacy Policy, Algolia Privacy Policy

Data Storage

• Where: Locally in your Chrome browser's localStorage
• Encryption: Not encrypted (data is not sensitive — just coin symbols)
• Access: Only accessible by this extension
• Size: Typically 50–100 bytes (your coin list)
• Persistence: Remains until you clear browser data or uninstall the extension

View Your Data

localStorage.getItem('crypto_chart_coin_options')

Delete Your Data

localStorage.removeItem('crypto_chart_coin_options')
