Private notes for your Google Calendar.
A personal annotation layer over your calendar. Prepare before meetings, jot down talking points, save follow-ups, all invisible to everyone else on the invite.
Three steps to private note-taking
Connect your calendar and start writing. No setup, no configuration, no passwords to remember.
Sign in with Google
One-click OAuth. We request read-only calendar access. Your credentials stay with Google.
See your events
Your upcoming meetings load instantly: titles, times, attendees, and descriptions. All read from your calendar, never modified.
Write private notes
Type your notes, meeting minutes, and action items. Everything is auto-saved securely as you go.
Built for the gap between calendars and notes
Purpose-built features for professionals who live in their calendar and need a private thinking space per meeting.
Truly Private
Notes are encrypted at rest with AES-256 and sent over TLS. Your notes’
existence is not discoverable by other event participants. We request only
calendar.readonly scope. We cannot modify your calendar, by
design.
Rich-Text Editor
Full Markdown editor with auto-save. Format your meeting prep, minutes, and action items. Never lose a thought to a browser crash.
Recurring Meetings
Two levels of notes: series notes for standing agendas shared across all occurrences, and instance notes for per-meeting details. Both visible side by side when you open a recurring event.
Full-Text Search
Search across all your notes instantly. Filter by date range to find prep notes from three weeks ago or action items from last quarter.
Auto-Save
Notes save as you type with debounce. Feels instant, always safe. Pick up right where you left off, even if you close the tab mid-sentence.
Hosted in the EU
Built and hosted in Germany. All data stays within the European Union, governed by GDPR’s strictest data protection standards.
Read-Only Calendar Access
Your calendar is displayed but never modified. We don’t create events, edit descriptions, or touch your data. Notes live in our encrypted database, completely separate from your calendar provider.
Privacy isn’t a feature. It’s the foundation.
We built prinocal because your thoughts belong to you. Every architectural decision starts from this principle.
Data Isolation
Notes are stored in our encrypted database, never written to shared calendar fields. Other participants cannot discover that you have notes on an event.
Encryption Everywhere
AES-256 encryption at rest. TLS in transit. OAuth scopes limited to calendar.readonly. The minimum possible access to do the job.
Zero-Knowledge Architecture
No note content in server logs. GDPR-ready with data export and account deletion that wipes your notes. Your data is yours to take or delete.
