Privacy Policy

Last updated: April 11, 2026

1. Who We Are

philter (“we,” “us,” “our”) operates the philter.io platform. This policy explains how we collect, use, and protect information when you use our services.

2. Information We Collect

Account information

Name, email address, and authentication credentials when you create an account.

Content you provide

Notes, meeting transcripts, voice recordings, and other materials you capture or upload to the platform.

Connected services

When you connect third-party services (Google Calendar, Microsoft Outlook, Slack, Fireflies.ai, Granola), we access data as authorized by you through those services’ OAuth flows or API keys. We only access the scopes you explicitly grant.

Usage data

Anonymous analytics (page views, feature usage) collected via PostHog. We do not sell or share this data with third parties for advertising.

3. How We Use Your Information

  • Provide, maintain, and improve the philter platform
  • Extract decisions, actions, and deliverables from your notes and transcripts using AI
  • Sync and display calendar events for scheduling context
  • Deliver notifications and briefings via email or Slack
  • Respond to support requests

4. Google Calendar Data

When you connect Google Calendar, we access your calendar events to display them in the philter calendar view, provide meeting preparation briefs, and optionally create calendar events for deadlines. We read event titles, times, attendees, and meeting links. We do not modify or delete your existing calendar events unless you explicitly enable calendar write-back. Your Google Calendar data is processed solely to provide philter’s features and is not used for advertising or shared with third parties.

5. Data Storage and Security

Your data is stored on Supabase (PostgreSQL) with row-level security enforced per organization. All data is encrypted in transit (TLS) and at rest. OAuth tokens are managed by Nango and automatically refreshed. API keys are stored in encrypted database columns with access restricted by role-based policies.

6. Data Sharing

We do not sell your data. We share data only with the service providers necessary to operate the platform:

  • Anthropic (AI processing)
  • Supabase (database hosting)
  • Vercel (application hosting)
  • Resend (transactional email)
  • Nango (OAuth token management)
  • Deepgram (speech-to-text)

Each provider processes data only as necessary to deliver their service and under their respective data processing agreements.

7. Data Retention and Deletion

Your data is retained as long as your account is active. You can delete individual items at any time. Deleted items are soft-deleted (archived) and permanently removed after 30 days. To delete your account and all associated data, contact us at founders@philter.io.

8. Your Rights

You may request access to, correction of, or deletion of your personal data at any time by contacting us. You may disconnect any connected service from Settings at any time, which revokes our access to that service’s data.

9. Changes

We may update this policy from time to time. We will notify you of material changes via email or an in-app notice.
