Privacy Policy
Last updated: June 2026
What we collect
MrCron collects your email address when you sign in via magic link. We store the projects, checks, and integration configurations you create. When integrations are connected, we store encrypted API credentials and periodically fetch metric snapshots from the connected services.
How we use it
Your data is used solely to provide the MrCron service — displaying metrics, evaluating alert rules, and sending alert notifications to your configured channels. We do not sell or share your data with third parties for marketing or analytics.
Integration credentials
API tokens and secrets you provide are encrypted at rest using AES-256-GCM before being stored in our database. They are only decrypted in memory during scheduled sync jobs. We use read-only API scopes wherever the connected service supports them. Disconnecting an integration permanently deletes the stored credentials.
Third-party services
We use Resend to deliver email notifications. Your email address is transmitted to Resend solely to deliver transactional alerts you have configured. We do not use any advertising or tracking pixels in emails.
Data retention
Raw metric snapshots are kept for 7 days. Aggregated rollups are kept longer. Alert firing records are kept for audit purposes. If you delete your account, all associated data including encrypted credentials, projects, checks, and metric history is permanently deleted.
