Privacy Policy

Last updated: June 13, 2026

not tonight. (“we”, “us”) takes privacy seriously — especially because the data you log here is personal. This policy explains what we collect, why, and the rights you have over it.

What we collect

  • Account data — name and email, managed by Clerk (our auth provider). We do not store passwords.
  • Log entries — date, intimacy outcome, selected reasons, quality ratings, mood and stress levels, lifestyle flags (exercise, alcohol, travel, conflict, illness), and any free-text notes you add.
  • Cycle & health data — period start/end dates, flow intensity, and symptoms you log. If you connect a health app (Google Fit, Fitbit) or upload an Apple Health export, we import the activity and menstrual data you authorize.
  • Partner link — if you invite a partner, their account ID is associated with yours. Partners cannot read each other's raw entries; only shared-view summaries are displayed.
  • Approximate location — your city/region to fetch local weather enrichment. We never store precise GPS coordinates.
  • Auto-enriched data — moon phase, weather conditions (temperature, precipitation, barometric pressure), and cycle calculations are computed server-side and stored against your entries to power pattern analysis.
  • Support conversations — if you contact our AI support chat, the conversation is stored so we can review reported issues. It is never used for training AI models.
  • Standard server logs — timestamps, IP addresses, browser type. Retained 30 days then deleted.

How we use it

  • To provide the app: calendar, cycle tracking, pattern analysis, and AI insights.
  • To send optional email notifications (weekly digest, period predictions) — disable anytime in Settings.
  • To generate anonymized aggregate benchmarks for Premium subscribers. Your personal data is never identifiable in these; buckets require a minimum of 100 contributors.
  • To diagnose bugs when you contact support.
  • To process subscription payments. We never see your card details — Stripe handles all of that.

We do not sell, rent, or share your personal data with any third party for advertising or marketing.
