Last updated: May 29, 2026

At Metrics Flow, we believe in being clear and open about how we collect and use data related to you. In the spirit of transparency, this policy provides detailed information about how and when we use cookies on our web application.

Strictly Functional Storage

Metrics Flow does not use advertising tracking cookies or sell your browsing history. We strictly limit storage to necessary authentication states, token verification, and client settings.

1. What are Cookies and Local Storage?

Cookies are small text files sent by us to your computer or mobile device. They are unique to your account or your browser. Local Storage is a modern web standard that allows applications to store key-value data in your browser securely and with higher speed.

2. How Metrics Flow Uses Browser Storage

We use both session cookies and HTML5 Local Storage for the following essential purposes:

Storage KeyTypePurposeDuration

user_creditsLocal StorageCaches your current AI credit balance for instant UI updates.Persistent
user_openai_keyLocal StorageOptionally stores your custom secret OpenAI key sk-... locally so it is never sent to our database.Until deleted

3. Third-Party Integrations

When you manage billing inside your Settings Panel, we utilize Stripe to securely process transactions. Stripe may set cookies necessary to prevent fraud, verify payments, and secure the credit card processing gateway. These cookies are subject to Stripe's Privacy and Cookie policies.

4. Your Control Options

Most web browsers allow you to manage cookie preferences through settings. If you limit the ability of websites to set cookies, you may worsen your overall user experience, as it will no longer be personalized to you. It may also prevent you from saving customized session settings like local API configurations.
