Privacy Policy
Last updated: June 16, 2026
Chronomore (“Chronomore”, “we”, “us”), operated by Rocco DiMauro, is a shared calendar app for couples and small groups. This policy explains what we collect, why, and the choices you have. Questions? Email privacy@chronomore.com.
Information we collect
Account information
We use Firebase Authentication for sign-in. Depending on how you sign in (email, Apple, or Google), we receive an account identifier and, if you provide it, your email address and display name.
Content you create
Events, groups, reminders, checklists, polls, journal entries, nicknames, and any photos you attach to events. This is stored with Google Firebase (Firestore and Cloud Storage) so we can provide the shared calendar to you and the people you choose to share with.
Google Calendar (optional)
If you link a Google account, we request read-only access (calendar.readonly) to display your Google events inside Chronomore. Only if you turn on mirroring do we request limited write access (calendar.app.created) to create a dedicated “Chronomore” calendar in your Google account. We store access tokens securely on our servers to keep your calendar in sync. You can unlink at any time, which stops syncing.
Diagnostics (optional — on by default, never in development builds)
To find crashes and improve the app, we use Firebase Crashlytics (crash reports) and Firebase Analytics (in-app usage such as which screens you view and core actions you take). These are tagged with your Firebase account identifier — a random ID, not your name or email — to help us debug. You can turn diagnostics off any time in Settings → Data (“Help improve Chronomore”).
Notifications
A device push token (Firebase Cloud Messaging) so we can send reminders and updates.
How we use information
- To provide and sync the shared calendar across the people you share with.
- To send reminders and notifications you’ve set up.
- To keep your Google Calendar in sync, if you’ve linked it.
- To diagnose crashes and improve the app, if diagnostics are on.
- To maintain the security and integrity of the service.
What we do not do
We do not track you across other apps or websites. We do not use App Tracking Transparency tracking. We show no ads. We do not sell your data or share it with data brokers.
How information is shared
- With people you share with: content you add to a shared group is visible to that group’s members. Items you mark private are not.
- Service providers: Google Firebase (Authentication, Firestore, Cloud Storage, Cloud Functions, Cloud Messaging, Crashlytics, Analytics, Hosting) and the Google Calendar API for linked accounts. These providers process data on our behalf.
- Legal: we may disclose information if required by law.
Data retention & deletion
We keep your data while your account is active. You can delete your account from inside the app at any time — see Delete your account. Routine backups and logs may persist for a short period before being overwritten.
Your choices
- Turn diagnostics on or off in Settings → Data.
- Unlink Google Calendar at any time.
- Control what is private versus shared.
- Delete your account and data.
Security
We use industry-standard measures, including encrypted transport and access controls, to protect your data. No method of transmission or storage is perfectly secure.
Children
Chronomore is not directed to children under 13 (or the minimum age required in your region), and we do not knowingly collect their personal information.
International users
Your data is processed on Google’s infrastructure, primarily in the United States.
