TL;DR
On the Free tier, all your data stays in your browser — no account, no analytics, no tracking. If you sign in for Pro or Business, we run servers for authentication, billing, and optional cloud sync — see "If You Create an Account" below for exactly what that involves.
Overview
EnvHub is a browser extension that provides visual environment indicators for web development. This privacy policy explains how EnvHub handles your data.
We believe privacy is a fundamental right. EnvHub was designed from the ground up to respect your privacy and keep your data under your control.
What We Collect
Data We Store Locally
The following data is stored locally in your browser only:
-
Project configurations (names, URLs, environment settings)
-
Custom environment types and styling preferences
-
Global settings (enabled state, display preferences, theme)
-
Recent color selections
Data We Do NOT Collect (Free tier, no account)
Without signing in, EnvHub does not collect, transmit, or share:
-
Personal information (name, email, etc.)
-
Browsing history
-
Website content
-
Analytics or usage data
-
IP addresses or device identifiers
-
Cookies or tracking data
If You Create an Account (Pro / Business)
Everything above describes the Free tier. If you sign in to unlock Pro or Business, that's opt-in, and it involves servers we run:
-
Account & billing: your email and subscription status are stored with our backend provider (Supabase) so you can sign in and manage your plan; payments are handled by Stripe and we don't store your card details ourselves.
-
Cloud sync: if you turn it on, your project/environment config and review data sync through our servers so your devices stay in step. It's off unless you enable it.
-
Optional integrations: connecting GitHub or Slack (to forward issues) requires an OAuth authorization you grant explicitly, and can be disconnected at any time.
None of this applies unless you create an account — the Free tier's data handling is exactly as described above.
Data Storage
All data is stored using your browser's built-in storage APIs:
| Storage Type |
Purpose |
| chrome.storage.sync |
Settings that sync across your devices (via your browser account) |
| chrome.storage.local |
Local-only data that stays on this device |
Your data never leaves your browser unless you have browser sync enabled, in which case it syncs through your browser's own sync mechanism (e.g., Chrome Sync). We have no access to this synced data.
Permissions Explained
EnvHub requests the following permissions, each with a specific purpose:
| Permission |
Why We Need It |
| storage |
Store your project configurations and settings locally |
| activeTab |
Detect the current page URL to show the correct environment indicator |
| tabs |
Enable quick-switch between environment URLs |
| host permissions |
Display the indicator bar on sites you configure |
Note: The extension only reads the URL of pages. It does not read or modify page content beyond injecting the visual indicator.
Third-Party Services
EnvHub does not use any analytics platforms or tracking tools, on the Free tier or otherwise. If you use an account-based feature, the relevant third party is limited to what that feature needs: Supabase (authentication, billing records, cloud sync) and Stripe (payment processing) for Pro/Business, and GitHub or Slack only if you explicitly connect them. No data is shared beyond that.
Your Data Rights
Export Your Data
You can export all your settings at any time through the extension's settings page. This gives you a complete copy of your data in JSON format.
Delete Your Data
Remove the extension from your browser to delete all stored data. Alternatively, clear extension data through your browser settings.
Children's Privacy
EnvHub is a developer tool not directed at children. Since we don't collect any personal information from anyone, we also don't knowingly collect information from children under 13.
Changes to This Policy
If we make changes to this privacy policy, we will update the "Last Updated" date at the top of this page. We encourage you to review this policy periodically.
