Privacy Policy

Last updated: February 25, 2026

1. Overview

DropAlert (“we,” “our,” or “the App”) is a price tracking application for iOS. We are committed to protecting your privacy. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your information.

2. Data We Collect

We collect only the minimum data necessary to provide the service:

2.1 Account Data

When you use DropAlert, an anonymous account is automatically created. This account is identified by a randomly generated unique identifier (UUID). We do not collect your name, email address, phone number, or any other personally identifiable information.

2.2 Watchlist Data

When you add apps to your watchlist, we store the app identifiers and related metadata (app name, price, icon URL) on our servers to enable price tracking and notifications.

2.3 Push Notification Token

If you enable push notifications, we store your device's push notification token to send price alerts. This token does not identify you personally and can be revoked at any time by disabling notifications in your device settings.

2.4 Subscription Data

If you subscribe to DropAlert Premium, subscription management is handled entirely by Apple through the App Store and by RevenueCat (our subscription infrastructure provider). We do not collect or store your payment information, credit card details, or Apple ID.

  • Name, email address, or phone number

  • Browsing history or search history
  • Contacts, photos, or other device data
  • Usage analytics or behavioral tracking
  • Any data for advertising purposes

4. How We Use Your Data

The data we collect is used solely for the following purposes:

  • Providing the price tracking service (monitoring App Store prices)
  • Sending push notifications when tracked app prices change
  • Managing your subscription status
  • Improving the reliability and performance of the service

We do not use your data for advertising, marketing, or any other purpose beyond providing the core service.

6. Data Retention

Your watchlist data is retained as long as you use the app. If you remove an app from your watchlist, the associated tracking data is deleted. If you delete the app, your anonymous account and all associated data will be automatically deleted after 30 days of inactivity.

7. Data Security

We implement appropriate technical measures to protect your data, including encryption in transit (TLS/SSL), encryption at rest, and Row Level Security (RLS) policies that ensure users can only access their own data.
