Crypto Price Alert ("we", "our", "the Extension") is a browser extension that monitors cryptocurrency prices on Binance and sends lock screen alerts to your device via Bark (iOS) or Ntfy (Android). This Privacy Policy explains how we collect, use, and safeguard your data. By installing and using the Extension, you agree to this policy.
| Data Category | When | Purpose & Storage |
|---|---|---|
| Bark Push Key (iOS) | You paste Bark URL in settings | Used to route push notifications to your iOS device via Bark. Sent to our backend for licensing checks and notifications. Stored locally. |
| Ntfy Topic (Android) | You generate/paste Ntfy topic | Used to route push notifications to your Android device via Ntfy. Sent to our backend for licensing checks. Stored locally. |
| Price Thresholds & Coin Settings | You set alert thresholds | Stored locally in chrome.storage.local. Never uploaded except in-memory during AI parser requests. |
When you use the AI command assistant (e.g. typing "notify me below 4000"), the extension transmits the text command, the current symbol, and the current price to our backend server over HTTPS to parse using Google Gemini API. This data is processed in-memory and is not stored, logged permanently, or linked to your identity.
Subscriptions are managed manually or via PayPal/USDT. When checking payment status, your Bark Key or Ntfy Topic acts as your anonymous user identifier (User Key). No email or password is required or collected for Crypto Price Alert.
To understand whether the Extension is working for users and to improve reliability, we may process a randomly generated anonymous install ID (a random string that cannot identify you in real life). This ID is used only for aggregated usage and uninstall statistics — for example, whether monitoring ran successfully that day, whether a push alert succeeded or failed, and optional short uninstall feedback if you choose to submit it. We do not sell this data, use it for advertising, or combine it with your name, email, or other personal identity information. Price levels, coin choices, and Bark/Ntfy credentials are not included in these statistics.
To provide core monitoring and alert delivery services, we interact with the following third parties:
| Provider | Data Shared | Purpose |
|---|---|---|
| Binance API | Coin Symbol (e.g., BTCUSDT) | To fetch public real-time cryptocurrency tickers. No user data is sent. |
| Bark API (https://api.day.app) | Bark Key, Alert Title, Message | To deliver iOS lock-screen push alerts. Only triggered when alert price thresholds are met. |
| Ntfy API (https://ntfy.sh) | Ntfy Topic, Alert Title, Message | To deliver Android lock-screen push alerts. Only triggered when alert price thresholds are met. |
| Google Gemini API | Text Command (via our backend proxy) | To parse natural language alarm expressions into structured configuration directives. |
The Extension uses Chrome's secure local storage (chrome.storage.local) to persist settings including: deviceType, barkUrl, ntfyTopic, barkSound, barkIsCritical, alertInterval, isMonitoringActive, chartInterval, an anonymous install ID used only for the statistics described above, and current monitoredCoin specifications. You can clear this data at any time by uninstalling the Extension or resetting settings.
Since we do not collect usernames, passwords, or emails, we identify your account status purely by your Bark Key or Ntfy Topic. You can request deletion of any transaction/activation records associated with your Key by contacting us at sd3179438@gmail.com.
We may update this Privacy Policy from time to time. The "Last updated" date will reflect the changes.
