DayNavi ("we", "our", "us") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
Account data: email address and display name you provide when registering.
Usage data: tasks (title, category, completion status, due time), daily energy level, mood check-ins, and notification interaction timestamps.
Calendar data: if you connect Google Calendar or your device calendar, we access upcoming events solely to display them in your day view and trigger transition alerts. Calendar data is never stored on our servers beyond the session.
Voice data: if you use Voice Brain-Dump, audio is sent to OpenAI Whisper for transcription and immediately discarded. We do not store voice recordings.
Analytics: anonymized usage events via PostHog (e.g. task completed, onboarding finished). No personal identifiers are sent to PostHog in production.
To provide core app functionality: syncing tasks and preferences across devices.
To power the AI Sidekick: your current task and energy context are sent to OpenAI to generate personalized check-ins and suggestions. No data is used to train OpenAI models.
To adapt notification timing: we store timestamps of when notifications were sent and opened to improve the timing of future reminders. This data is stored per user and never shared.
To display your personal stats: tasks completed, streaks (positive only), and usage patterns.
We do not use your data for advertising and do not sell it to third parties.
Your data is stored securely on Supabase (supabase.com), hosted in US data centers. Analytics events are processed by PostHog (posthog.com). AI features use the OpenAI API (openai.com); prompts are not retained by OpenAI. Payments are processed by RevenueCat (revenuecat.com) and the respective app store (Apple / Google).
All processors operate under appropriate data processing agreements and comply with applicable privacy law.
Your data is retained as long as your account is active. You can delete your account at any time from the app settings. All personal data is permanently deleted within 30 days of account deletion.
Depending on your location, you may have the right to access, correct, delete, or export your personal data, and to object to or restrict processing.
To exercise any of these rights, contact us at [email protected].
DayNavi is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided us personal data, please contact us immediately.
We may update this policy from time to time. We will notify you of significant changes via the app. Continued use of the app after changes constitutes acceptance of the updated policy.
