Cookie Policy

Last Updated: March 2026. How we use cookies and similar technologies.

In simple words
  • We use cookies to keep you logged in and remember your preferences (these are essential).
  • We use Google Analytics cookies only after you say yes — to understand how people use the app.
  • We also store some data in your browser (localStorage) for faster performance — this syncs to our servers.
  • You can choose "Essential Only" to block analytics. You can clear cookies anytime from your browser.
  • We never use cookies for advertising or tracking you across other websites.

1. What are Cookies?

Cookies are small text files stored on your device that help us recognize you and remember your preferences. We also use localStorage (browser storage) to cache data locally for faster performance — this data is synced to our servers for backup and multi-device access.

2. Types of Cookies & Storage We Use

Essential Cookies (Always active — required for the app to work)

Necessary for authentication, security, and basic functionality. Cannot be disabled.

glx-locale-manualManually selected country/language1 year

Analytics Cookies (Optional — requires your consent)

We use Google Analytics 4 to understand how users interact with the app. These cookies are only set after you click "Accept All" in the cookie banner. IP addresses are anonymized. No personal data or photos are shared with Google for advertising.

CookiePurposeDuration
_gaDistinguishes unique visitors (anonymized)2 years
_ga_*Maintains session state for GA42 years

Local Storage (Browser) (For performance — synced to our servers)

We use your browser's localStorage and IndexedDB to cache data locally for instant performance. Important: This data is synced to our cloud servers (Supabase) for backup, multi-device access, and AI processing. Local storage is not a substitute for server storage — it is a performance cache.

IndexedDB (gx-store)Scan results, progress photos, health data cacheYes
gx_cycle_v1Cycle tracking data cacheYes
gx_mental_v1Mood, sleep, wellness data cacheYes
gx_diet_v1Diet and meal logging cacheYes

3. Third-Party Cookies

We minimize the use of third-party cookies. When you make a payment, Razorpay may set cookies required for secure payment processing. These are governed by Razorpay's Privacy Policy. Google Tag Manager may also set cookies for analytics measurement.

4. Your Control

You can manage your cookie and data preferences:

  • Accept All: Essential + analytics cookies are enabled. Full app experience.
  • Essential Only: Only authentication and preference cookies are active. Google Analytics is not loaded. No analytics data is collected.
  • Browser Settings: You can clear or block cookies from your browser's settings at any time.
  • Clearing Local Storage: Clearing your browser data will remove the local cache, but your data remains safe on our servers and will re-sync when you log in.
  • Clearing Cookies: Will sign you out, reset your theme preference, and reset your cookie consent choice.

5. We Do Not Use Cookies For

  • Targeted advertising or ad retargeting
  • Tracking you across other websites

  • Building advertising profiles
