Privacy Policy

Last updated: March 31, 2026

1. Information We Collect

Account information. When you create an account we collect your email address, name, and authentication credentials. If you sign in via Google OAuth, we receive your Google profile information as authorized.

Usage data. We collect server logs including IP addresses, request timestamps, endpoints accessed, and response codes. These logs are retained for operational and security purposes.

Service data. Data you store through our services (contacts, emails, files, jobs, notifications) is stored in isolated PostgreSQL databases per service. Each tenant's data is logically separated via row-level isolation.

2. How We Use Your Information

We use your information to:

  • Provide, maintain, and improve our services
  • Authenticate your identity and manage sessions
  • Send transactional communications (password resets, security alerts)
  • Monitor service health and prevent abuse
  • Comply with legal obligations

We do not sell your personal information to third parties.

3. Data Storage and Security

All data is stored on infrastructure we control. Passwords are hashed using industry-standard algorithms. API keys are stored as SHA-256 hashes. Sessions use HMAC-signed cookies. All inter-service communication uses authenticated REST calls.

File uploads via the Storage service are stored in S3-compatible object storage with access logging enabled.

4. Data Retention

We retain your data for as long as your account is active. You may request deletion of your account and associated data by contacting us. Server logs are retained for up to 90 days. Files governed by lifecycle policies are automatically deleted per the configured rules.

5. Third-Party Services

We integrate with the following third-party services when you opt in:

  • Google OAuth - for sign-in and calendar synchronization
  • Twilio - for SMS notification delivery
  • Firebase Cloud Messaging - for push notifications

Each integration is governed by the respective provider's privacy policy.

6. Cookies

We use session cookies scoped to .rust.solutions for authentication across our services. These are strictly functional - we do not use tracking or advertising cookies.

7. Your Rights

You have the right to access, correct, or delete your personal data. You may export your contacts and calendar data at any time. To exercise these rights, contact us at the address below.
