Privacy Policy

Last updated: May 2026

Calendar72 is built to be calm and predictable. This page explains exactly what data we collect when you use the iOS app and the calendar72.app website, what we do with it, and how to delete it.

1. What we store

When you create a Calendar72 account we store:

• Your email address and a Firebase-generated user ID — to authenticate you. Provided either directly (email + password sign-up), via Sign in with Apple (Apple may relay a private address), or via Sign in with Google.
• A list of calendar IDs you've subscribed to in the app (e.g. the ID of FC Bayern München's fixture calendar) — stored at users/{uid}/subscriptions/{calId} in Firestore.
• Your favourite-event-team picks (e.g. teams selected for World Cup 2026) — stored at users/{uid}/preferences/main in Firestore.
• A display name, if Sign in with Apple or Sign in with Google provides one on first sign-in.

2. What we do NOT store

• The actual calendar events themselves — those live in your Apple Calendar after you subscribe. We never see what's on your calendar.
• Your location.
• Your device identifiers, IDFA, or any advertising ID.
• Your contacts.
• Any analytics or behavioural tracking data.

3. No trackers, no ads

Calendar72 does not embed any tracking SDKs. No Google Analytics, no Meta pixel, no third-party advertising network, no fingerprinting library. The iOS app only connects to:

• Firebase Authentication (Google) — to sign you in.
• Cloud Firestore (Google) — to store the few pieces of data listed in section 1.
• Sign in with Apple — when you choose that sign-in method.
• Sign in with Google — when you choose that sign-in method.
• OpenLigaDB — read-only, anonymous, to fetch public Bundesliga fixture data.

The landing page (calendar72.app) loads the Inter font from Google Fonts. No cookies are set on first visit.

4. How long we keep your data

As long as your account exists. When you delete your account (see section 5), all of it is erased.

5. Deleting your account and data

Open the Calendar72 iOS app → Account tab → Delete Account. You will be asked to confirm and, depending on how you signed in, to re-authenticate. Once confirmed:

• Your Firestore documents (subscriptions, preferences, user record) are immediately deleted.
• Your Firebase Authentication user is immediately deleted.
• Calendar subscriptions you already added to your Apple Calendar stay there — they're under your control. The privacy policy explains how to remove them in the offboarding flow inside the app.

If you cannot access the app for any reason and need your data deleted, email us (see section 9) and we will do it manually.

6. Your rights (GDPR)

If you are in the EU/EEA, you have the right to access, rectify, port, and erase your personal data under the General Data Protection Regulation. Most of these you can exercise directly in-app; for anything we cannot fulfil in-app, contact us.

7. Children

Calendar72 is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal data, contact us and we will delete it.

8. Changes to this policy

If we change this policy in a way that materially affects what we collect or how we use it, we will note the change at the top of this page and update the "Last updated" date.
