Privacy Policy

Last updated: 25 June 2026

Tachycalendar (“the app”) correlates your Google Calendar meetings with your Oura heart-rate data to show which meetings raise your heart rate. This policy explains what we collect, why, and how to remove it.

What we access

• Google Calendar (read-only): event titles, start/end times, attendee email addresses, and whether an event has a video link — for the last ~6 weeks. We request the calendar.events.readonly scope and your email address only.
• Oura: your heart-rate time series for the periods covering your meetings, plus basic account identity.

What we do with it

We compute a “stress score” per meeting by comparing your heart rate during the meeting to your daily baseline, and store the results so you can view trends over time. That is the only purpose. We do not sell your data, use it for advertising, or share it with third parties.

What we store

Scored meeting summaries (title, time, attendees, heart-rate averages, score) and OAuth tokens for Google and Oura are stored in our database so the app can refresh your data. Raw heart-rate samples are processed in memory and not retained.

Deleting your data

You can disconnect at any time by revoking access in your Google account and Oura account. To have your stored data erased, contact us and we will delete your user record and all associated meetings.
