Cookie Policy

Last updated: 13/04/2026

At Trade Buddy, we value your trust and are committed to being clear about how we collect and use your data. This Cookie Policy explains what technologies we use, why we use them, and how you can control your preferences.

What are cookies and similar technologies?

Cookies are small text files stored on your device by your web browser. They typically contain a domain name, an expiration date, and a unique identifier. We also use localStorage, a browser feature that stores data locally on your device. Together, these technologies help our platform function correctly, stay secure, and improve over time.

Technologies we use

We group the technologies on our platform into two categories: Essential and Analytics & Advertising. Essential technologies are always active because our platform cannot function without them. Analytics & Advertising technologies only activate after you give consent.

Essential (always active)

Technology	Type	Purpose	Duration
Supabase Auth	localStorage	Keeps you logged in and manages your secure session	Until you log out
tb_cookie_consent	Cookie	Remembers your cookie consent choice so we do not ask again	365 days

Analytics & Advertising (require your consent)

Technology	Type	Purpose	Duration	Data processed in
PostHog	Cookie + localStorage	Helps us understand how people use Trade Buddy so we can fix issues and improve the experience	1 year	EU
Google Ads (AW-18022786140)	Cookies (gcl, _ga)	Measures which of our Google ads lead people to Trade Buddy and helps us spend our advertising budget effectively	90 days - 2 years	US
Meta Pixel (906769031942357)	Cookies (_fbp, _fbc)	Measures which of our Facebook and Instagram ads lead people to Trade Buddy and helps us reach the right audience	90 days - 2 years	US

International data transfers

Google and Meta process data in the United States under Standard Contractual Clauses approved by the UK Information Commissioner's Office. PostHog processes data within the European Union. Supabase processes data in the United States. Your essential session data never leaves your device.

How to control your preferences

When you first visit Trade Buddy, a consent banner gives you two choices: Accept All or Reject All. If you reject, analytics and advertising technologies will not load - only essential technologies will run.

You can change your choice at any time by clicking "Manage Cookie Preferences" in the footer of any page. This clears your saved choice and shows the consent banner again.

Disabling analytics and advertising technologies will not affect core platform features like logging in, managing your account, or using the platform.

Changes to this policy

We may update this Cookie Policy when we add or remove technologies. Material changes will be communicated via our consent banner or by email. The date at the top of this page shows when it was last revised.
