Privacy Policy

Last updated: May 19, 2026

Catholic Index is operated by Tagaste LLC, a California limited liability company, which is the data controller responsible for your information.

Information We Collect

Website. We collect email addresses when you use features like saving parishes or lighting candles. This information is used solely to provide you with these services.

MCP API. When you use Catholic Index through AI assistants (like ChatGPT, Claude, or Cursor), we log tool call inputs including search locations, queries, and church IDs. These logs do not contain any personal information such as names, email addresses, or end-user IP addresses.

Analytics. We use Umami, a self-hosted, cookie-free analytics tool, to understand how visitors use our site. No personal data or tracking cookies are involved.

Session replay. We use PostHog for anonymous usage analytics and session replay on both the website (10% of visits) and the mobile app, with all text inputs automatically masked. The Confession Companion is fully excluded from session replay — see the “Confession Companion” section below. For visitors in the EU and UK, website analytics data is stored only for the duration of your visit. For other visitors, a first-party cookie is used to understand return visits.

Confession Companion

Your examination of conscience stays on your device. We never collect which sins you select, anything you type, or how many items you review, and the Confession Companion screens are masked from session replay and blocked from screenshots. We see only anonymous feature usage, such as whether a session was started — and that is not tied to your identity.

The examination of conscience was inspired by ConfessIt, an open-source project (MIT License).

How We Use Your Information

Email addresses allow us to save your preferences and may be used to send you occasional updates about new features. We do not sell or share your personal information with third parties.

Third-Party Services

Catholic Index integrates with the following third-party services:

  • YouTube — livestream and homily video links
  • OpenAI — homily search queries are sent to OpenAI to generate semantic embeddings for search matching; queries are not used by OpenAI for training
  • PostHog — anonymous usage analytics and session replay to improve the site experience; data is processed in the United States

Your Rights

You can request access to, correction of, or deletion of any personal information we hold about you by contacting us. We will respond within 30 days.

If you are located in the European Economic Area, United Kingdom, or Switzerland, you have additional rights under the GDPR, including the right to withdraw consent at any time, request erasure of your data, and lodge a complaint with your local data protection authority.

International Data Transfers

Your data may be processed and stored in the United States. By using Catholic Index, you acknowledge this transfer. We use first-party infrastructure and do not share personal data with third-party advertisers.
