Privacy Policy

Last updated: April 2026

1. What we collect

Jazylu collects only what is necessary to provide the service:

  • Your email address (used to identify your account)
  • Subscription data you manually enter (name, amount, dates)
  • Preferred language (stored in a cookie)
  • If you vote on mobile app interest: platform choice and locale
  • Anonymous page view data via Vercel Analytics (no personal info)

2. How we use your data

Your data is used solely to run Jazylu — displaying your subscriptions, sending no marketing emails, and improving the product. We do not sell, share, or rent your data to third parties.

3. Authentication

You can sign in with Google or email/password. Authentication is handled by Supabase. When you use Google Sign-In, we receive your name and email from Google — nothing else.

4. Data storage

All data is stored in a Supabase (PostgreSQL) database hosted on AWS infrastructure in the EU region. Access is protected by row-level security — you can only read and write your own data.

5. Analytics

We use Vercel Analytics to collect anonymous page view data — which pages are visited, country, device type, and referrer. No personal information is collected, no cross-site tracking, and no advertising profiles are built. Data is aggregated and cannot be tied to individual users.

6. Cookies

We use a single cookie (lang) to remember your language preference, and session cookies set by Supabase to keep you logged in. No advertising or third-party tracking cookies are used.

7. Your rights

You can delete your account and all associated data at any time by contacting us. We will remove everything within 30 days.
