1. Local-First Privacy Architecture
At How Many Days Until (howmanydaysuntil.app), your privacy is our primary engineering focus. Custom countdowns created in your Personal Time Atlas reside securely in your browser's local sandbox storage (LocalStorage). We do not transmit or store your personal milestones, custom reminders, or private anniversary notes on central servers.
2. Analytics & Cookies
We do not require account registration, passwords, or personal identifiable information (PII) to access countdown timers. We use minimal, privacy-friendly telemetry strictly to evaluate site performance, optimize core web vitals, and diagnose technical errors.
3. Third-Party Integrations
Our calendar export tools (iCalendar / Apple Calendar, Google Calendar, Outlook) run entirely client-side. When you download a .ics file or trigger a calendar URL, your schedule parameters are formatted directly on your device without server interception.
