1. Introduction
SubChk ("we", "us", or "our") operates subchk.com. This policy explains how we collect, use, disclose, and safeguard information when you use the site and the service.
We never store the contents of your emails. We only extract subscription information (service name, amount, renewal date) and discard the original email text immediately.
2. Information We Collect
2.1 Account Information
Email address, hashed password, name, preferences, timezone, and the language you choose.
2.2 Gmail Data
When you authorize Gmail, we request read-only access to scan invoice and subscription emails. We extract structured subscription fields from those emails. Email contents are processed in memory and discarded. They are never stored.
2.3 Subscription Data
Service names, plans, amounts, renewal dates, usage metrics, and categories that you enter or that we detect.
2.4 Usage Data
Log data such as IP address, browser type, pages visited, and referring URL, collected to operate and improve the service.
3. How We Use Your Data
- •To provide and improve subscription tracking, renewal alerts, and parsing.
- •To send product email you opted into, including welcome, scan results, and renewal reminders, in your saved language.
