How your data stays yours.
Nudge collects the minimum it needs to work. We never sell your data, and we delete all of it when you ask us to close your account.
A minimum information policy.
Nudge (“we,” “us,” or “our”) operates the Nudge application and website at usenudge.ai (the “Service”). This Privacy Policy describes how we collect, use, store, and share your information when you use our Service, which includes our web application, mobile applications, and AI-powered task management features.
We are committed to protecting your privacy and handling your data with transparency. We collect only the minimum information necessary to provide our Service and we never sell your personal information to third parties.
What Nudge collects.
Account Information
Email address and name
Collected when you sign up via email, Google Sign-In, or Sign in with Apple. Used for authentication, account management, and service communications.
Authentication credentials
If you sign up with email, your password is securely hashed using bcrypt. If you use Google Sign-In, we store only an OAuth token, never your Google password.
Task and Productivity Data
Tasks and reminders
Task titles, descriptions, notes, deadlines, priorities, urgency levels, subtasks, and completion status.
Chat and conversation history
Messages you exchange with the Nudge AI assistant, including task-related queries and responses.
Usage patterns and preferences
Task completion patterns, scheduling preferences, and behavioral insights that help the AI provide personalized reminders.
Settings and Device Information
User preferences
Timezone, notification preferences, quiet hours, working hours, and AI feature settings.
Device tokens
Firebase Cloud Messaging tokens used to deliver push notifications to your devices. These are device-specific identifiers and can be revoked at any time.
Calendar Data (Optional)
If you choose to connect Google Calendar, we access event titles, times, attendee counts, and free/busy status to help schedule reminders around your existing commitments. See the Google Calendar Integration section below for full details on how we handle this data.
Put to work for your reminders.
We use the information we collect for the following purposes:
- To create and manage your account and authenticate your identity
- To store, organize, and display your tasks, notes, and reminders
- To send you intelligent, context-aware push notifications and reminders at optimal times
- To power AI features such as natural language task parsing, conversational task management, and smart scheduling
- To sync your tasks and data across your devices (web and mobile)
- To respect your calendar availability when scheduling reminders (if calendar integration is enabled)
- To learn your preferences and patterns over time so reminders become more effective
- To communicate important service updates, security alerts, and account-related notifications
- To monitor and improve the reliability and performance of the Service
We do not use your personal information for advertising purposes. We do not sell, rent, or trade your personal information to third parties.
AI is built in.
Nudge processes your data to provide assistance:
- Parse natural language input to create tasks with dates, priorities, and recurrence
- Provide a conversational AI assistant for task management, scheduling, and productivity guidance
- Suggest optimal reminder timing based on your completion patterns and habits
- Generate contextual, motivating reminder messages
- Learn and store relevant memories and preferences from your conversations to personalize the experience over time
How AI processing works. Your task content and conversation context are sent to third-party AI providers (Anthropic Claude and OpenAI) for processing. This data is transmitted securely over encrypted connections.
Your data is not used to train AI models. Both Anthropic and OpenAI have committed in their API terms that data sent through their APIs is not used for model training. Your conversations remain private.
Memory system. Nudge may store learned observations, preferences, and patterns from your conversations as “memories” to improve future interactions. These memories are stored in your account and are not shared with other users. You can read, edit, and delete any memory on the Memory screen in the app.
Your calendar stays yours.
Nudge offers an optional Google Calendar integration to help schedule reminders around your existing commitments. This section explains exactly how we access and use your Google Calendar data.
What We Access
- Read access to your Google Calendar events (titles, times, attendee counts, free/busy status) to understand your schedule
- Write access limited to a dedicated “Nudge” calendar only, using the
calendar.app.createdscope
How We Use Calendar Data
- To display your schedule alongside tasks in the Nudge calendar view
- To avoid sending reminders during meetings or busy blocks
- To suggest optimal times for task scheduling based on your free time
- To provide the AI assistant with schedule context for better recommendations
Your Control
- Calendar integration is entirely optional and requires your explicit consent via Google OAuth
- You can disconnect Google Calendar at any time from Settings
- When you disconnect, we revoke our access token and stop syncing calendar data
- Previously synced calendar events are deleted from our servers upon disconnection
Nudge's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Who else sees what.
Nudge integrates with the following third-party services to provide functionality. Each service receives only the minimum data necessary for its purpose:
Google Sign-In
Authentication via OAuth 2.0. Receives your email and profile name.
Google Calendar API
Optional calendar sync. Read-only access to your calendars; write access to Nudge calendar only.
Anthropic (Claude API)
AI assistant processing. Receives task context and conversation messages. Data not used for model training.
OpenAI API
Supplementary AI processing and embeddings for the memory system. Data not used for model training.
Firebase Cloud Messaging
Push notification delivery on web and mobile. Receives device tokens and notification content.
Sentry
Error tracking and performance monitoring. Error reports may include your user ID, email, and IP address so we can reproduce and fix what broke for you.
PostHog
Product analytics on web and mobile. Receives usage events tied to your account so we can see what works and what doesn’t.
ElevenLabs
Voice generation. Receives the text of a reply when Nudge speaks it aloud. Never receives your recordings.
How long we keep it.
We retain your data for as long as your account is active or as needed to provide the Service. Specifically:
- Account data is retained until you delete your account
- Tasks and notes are retained until you delete them individually or delete your account
- Chat conversation history is retained for the duration of your account
- AI memories and learned preferences are retained until you delete them on the Memory screen or your account is deleted
- Calendar data is deleted when you disconnect Google Calendar or delete your account
- Device tokens are removed when you unregister a device or delete your account
- Error logs (Sentry) are retained for 90 days
When you delete your account, all associated data is permanently removed from our servers within 30 days. Backup copies in encrypted backups may persist for up to 90 days before being automatically purged.
How we protect it.
We take the security of your data seriously and implement industry-standard measures to protect it:
- All data in transit is encrypted using TLS (HTTPS)
- Passwords are hashed using bcrypt with salting
- Authentication uses JWT tokens with short-lived access tokens (1 hour) and longer-lived refresh tokens (90 days)
- Database access is restricted and credentials are never exposed in client-side code
- Third-party API keys are stored securely as environment variables, not in source code
- We use Sentry for real-time error monitoring to quickly detect and respond to security issues
While we implement robust security practices, no method of electronic transmission or storage is 100% secure. We cannot guarantee absolute security but commit to promptly notifying affected users in the event of a data breach.

Continued use of the Service after changes take effect constitutes acceptance of the updated policy.
