Privacy Policy

Last updated: March 2026

Overview

Flaggr is an open-source feature flag platform. We are committed to protecting your privacy and being transparent about how we handle data.

Data We Collect

Account Information

When you create an account, we collect your email address and display name for authentication purposes.

Usage Data

We collect anonymous usage metrics to improve the platform, including page views, feature usage patterns, and error reports. We do not track individual user behavior across sessions.

Feature Flag Evaluation Data

When flags are evaluated through our API, we process the evaluation context you provide (such as user IDs and targeting attributes). This data is used solely for flag evaluation and observability purposes.

How We Use Your Data

• To authenticate you and manage your account
• To provide feature flag evaluation services
• To generate aggregated, anonymized usage metrics
• To improve the platform and fix bugs

Data Storage & Security

Data is stored in Google Cloud Firestore with encryption at rest and in transit. We use industry-standard security measures including role-based access control, audit logging, and encrypted communications (TLS 1.3).

Third-Party Services

We use the following services to operate Flaggr:

• Google Firebase — Authentication and data storage
• Vercel — Hosting and edge computing
• Upstash Redis — Caching and rate limiting

Your Rights

You can request to:

• Access your personal data
• Delete your account and associated data
• Export your data in a machine-readable format

Self-Hosted Deployments

If you self-host Flaggr, no data is sent to us. All data remains within your infrastructure. This privacy policy applies only to the hosted service at flaggr.dev.
