Privacy Policy

Last updated: April 14, 2026

Overview

Remind is a macOS desktop application that provides meeting reminders and optional AI-powered meeting preparation. We are committed to protecting your privacy. This policy explains what data Remind accesses, how it is used, and how it is stored.

What Data We Access

Google Calendar Data

When you connect your Google account, Remind uses Nylas — a third-party connectivity platform — to securely authenticate via OAuth and request read-only access to your Google Calendar. This allows Remind to:

Read your upcoming calendar events (title, time, location, attendees, meeting links)
Display meeting reminders at configured times
Extract video meeting links (Zoom, Teams, Google Meet, Webex) for one-click join

Remind does not create, modify, or delete any calendar events. Access is strictly read-only.

Google Account Profile

Remind accesses your basic Google profile (email address) solely to display which account is connected in the app settings.

Email Data (Optional)

Remind searches for recent email threads with your meeting attendees via Nylas. Nylas handles OAuth authentication with your email provider (Gmail, Outlook, etc.) — Remind never sees your email password. Email search requests are proxied through Remind's backend to Nylas. This email content is:

Not stored — email snippets pass through Remind's backend and Nylas but are not stored by either
Read in memory only — email content is read in memory on your Mac, included in your AI provider's context, and discarded
Sent to your AI provider — the content is passed to your chosen AI provider (using your own API key) as context for generating your meeting briefing

Only the AI-generated briefing summary is cached locally on your Mac (for 30 days).

Slack Data (Optional)

If you connect Slack, Remind searches for recent messages with your meeting attendees. Slack messages are fetched on-demand, passed to your AI provider for context, and discarded immediately. No Slack message content is stored on disk or sent to Remind's servers.

Notion Data (Optional)

If you connect Notion, Remind searches your workspace for pages relevant to your upcoming meetings (by attendee name, company, or meeting title). Page titles and content snippets are fetched on-demand, passed to your AI provider for context, and discarded immediately. No Notion content is stored on disk or sent to Remind's servers.

How Your Data Is Used

Calendar events are fetched periodically (every 2 minutes) and stored temporarily in memory to power reminders. They are not persisted to disk or sent to any external server.
Attendee information (names and email addresses from calendar events) may be used by the optional AI meeting prep feature. If enabled, this information is sent directly to your chosen AI provider using your own API key. It is never sent to our servers.
OAuth tokens and grant IDs are stored securely in your Mac's Keychain. They are used only to authenticate with your connected providers (Google, Microsoft, Slack, Notion) via Nylas or direct OAuth.

What We Do NOT Do

We do not sell, share, or transfer your data to any third parties
We do not use your data for advertising
We do not store your calendar data on any server
We do not collect analytics or behavioral tracking beyond basic install information (see below)
We do not store your raw email content on disk or on any server

Data Storage

All data stays on your Mac:

OAuth tokens: macOS Keychain (encrypted by the operating system)
App settings: macOS UserDefaults (local to your machine)
AI research cache: Local JSON files in ~/Library/Application Support/Remind/ResearchCache/ (if AI features are used; cached entries expire after 30 days)

No calendar data, tokens, or personal information is transmitted to Remind's servers beyond what is described below.

Data Sent to Our Servers

Our backend runs on Supabase infrastructure (edge functions and database). The following data is transmitted:

Install Tracking: When you connect a calendar, Slack, or Notion account, Remind sends a privacy-safe SHA256 hash of your device's hardware UUID, your email address, and the account provider type (e.g., Google, Microsoft, Slack, Notion) to our server. This is used solely to understand who is using the app. No calendar data, meeting content, or usage behavior is included.

Crash Reporting: Remind uses Sentry for crash and error reporting. Crash reports include a device identifier (hardware UUID) and stack trace. To help diagnose user-reported issues, your email address (from your connected calendar account) is also associated with crash reports in Sentry. No calendar data, email content, or meeting information is included in crash reports.

Briefing Feedback (Opt-in): If you choose to rate a meeting briefing (thumbs up/down), the following is sent to our server: the AI-generated briefing text, your rating, optional written feedback, the number of attendees, and whether the meeting is recurring. No raw email, Slack, or Notion content is included. No data is captured unless you actively click a rating button.

SMS and Voice Call Reminders (Optional): If you enable SMS or voice call reminders, your phone number and meeting information (title, timing, join link) are sent to our server for delivery via Twilio. Voice calls use Amazon Polly (accessed via Twilio) for speech synthesis. SMS and voice call reminders are limited to 300 per month combined.

Phone Number Tracking: When you save a phone number for notifications, your phone number and a SHA256-hashed device ID are sent to our backend for usage tracking.

Notification Consent: Explicit opt-in consent is collected (with timestamp) before enabling SMS or voice call notifications. Consent records are stored locally on your device.

Third-Party Services

Google APIs: Calendar data is fetched directly from Google using OAuth 2.0. Governed by Google's Privacy Policy.
Nylas: Remind uses Nylas, a third-party platform, to securely authenticate and connect your Google or Microsoft account and to access calendar and email data on your behalf. Nylas handles the OAuth flow with your provider — Remind never sees your account password. Nylas is SOC 2 Type II certified, ISO 27001 and ISO 27701 certified, HIPAA/HITECH compliant, and adheres to GDPR and CCPA requirements. For more details, see Nylas Security and Nylas's Privacy Policy.
Slack (optional): If you connect Slack, Remind accesses your Slack workspace via OAuth to fetch recent messages with meeting attendees. Governed by Slack's Privacy Policy.
AI Providers (optional): If you enable AI meeting prep and provide your own API key, attendee names and recent context from email and Slack (if connected) are sent to your chosen AI provider (Anthropic, OpenAI, or Google) for research. This goes directly from your Mac to the AI provider — never through our servers. All three providers' public API terms prohibit using API input data to train their models. Governed by the respective provider's privacy policy.
Notion (optional): If you connect Notion, Remind accesses your workspace via OAuth to search for relevant pages. Governed by Notion's Privacy Policy.
Amazon Polly (voice calls): When voice call reminders are enabled, Amazon Polly (accessed via Twilio) is used to generate voice audio for call reminders.
Resend: Remind uses Resend to send admin notification emails when users connect new accounts or phone numbers. Only the email address or phone number and provider type are included. Governed by Resend's Privacy Policy.
Sentry: Remind uses Sentry for crash reporting and error tracking. Your device UUID and email address are set in Sentry's user context to help diagnose user-reported issues. Governed by Sentry's Privacy Policy.
Supabase: Our backend API and database run on Supabase. Install tracking, feedback, and SMS delivery are processed through Supabase edge functions. Governed by Supabase's Privacy Policy.
Twilio (optional): If you enable SMS or voice call reminders, your phone number and meeting information are sent to Twilio for message and call delivery. Voice audio is generated by Amazon Polly via Twilio.

Revoking Access

You can disconnect any account at any time from Remind's Settings > Accounts. You can also revoke access from your Google Account permissions page or Microsoft Account permissions page. To disconnect Slack or Notion, use Settings > Accounts or revoke access from the respective service's settings. When you disconnect any account, all stored tokens are deleted from your Keychain.

Google API Services User Data Policy

Remind's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Children's Privacy

Remind is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date.
