Privacy Policy

Last updated: February 2026

What we collect

When you sign in with Google, we receive your email address and basic profile information. This is used solely to identify your account and sync your data across devices.

Your calendar data

Decavu stores your notes, hourly events, birthdays, and preferences. All data is stored locally in your browser first, and synced to our cloud database (hosted on Supabase) when you're signed in.

If you enable the Google Calendar overlay, Decavu reads your calendar events in read-only mode. These events are cached temporarily in your browser (5-minute TTL) and are never stored on our servers.

What we don't do

We don't sell, share, or transfer your data to third parties
We don't use your data for advertising
We don't track you across other websites
We don't use analytics or tracking scripts

Data storage

Your data is stored in a Supabase-hosted PostgreSQL database with row-level security. Only you can access your own data. Automatic backups are kept to protect against accidental data loss.

Data deletion

You can delete all your data at any time by signing out. To request complete account deletion, contact support@decavu.com.

Cookies

Decavu uses localStorage for app state and authentication. We don't use tracking cookies.

Changes

We may update this policy from time to time. Material changes will be noted on this page.
