Alex. Cookie Policy
Version 1.0 · Last updated: 30 September 2026
This policy explains how GWB Technologies Ltd (Alex.) uses cookies and similar technologies (such as local storage and pixels) on www.getalex.app and in the Alex app. It should be read with our Privacy Policy.
1. Your choices
When you first visit our website we ask whether you accept non-essential cookies. Nothing non-essential runs until you click Accept all. Reject non-essential is just as easy. You can change your mind at any time with the Cookie settings link in the footer of every page. You can also block or delete cookies in your browser settings, although parts of the site (such as logging in) may then stop working.
2. What we use
Strictly necessary (always on)
These are needed to provide the service you ask for, keep it secure, or remember your cookie choice. The law does not require consent for them.
| Name / type | Provider | Purpose | Duration |
|---|---|---|---|
| Supabase authentication session (local storage and/or cookie beginning `sb-`) | Alex (Supabase) | Keeps you logged in securely | Until you log out or the session expires |
| `cookie_consent` (cookie and local storage) | Alex | Remembers whether you accepted or rejected non-essential cookies | 12 months |
| Stripe cookies (e.g. `__stripe_mid`, `__stripe_sid`) | Stripe | Fraud prevention and security on checkout pages only | Up to 12 months / 30 minutes |
| App preferences (local storage) | Alex | Remembers settings such as units and theme | Until you clear them |
Our error monitoring (Sentry) does not use cookies to track you. Health data is removed from error reports before they leave your device, and session replay is switched off.
Marketing (only with your consent)
| Name | Provider | Purpose | Duration |
|---|---|---|---|
| Meta Pixel (e.g. `_fbp`, `fr`) | Meta Platforms Ireland / Meta Platforms Inc. | Measures whether our adverts on Facebook and Instagram lead to visits or sign-ups on our website, and helps show our adverts to people who may be interested | Up to 3 months |
The Meta Pixel only runs on our public marketing pages. It never runs inside the app, on pages where you are logged in, or on any page that shows health information, and we never send health data to Meta. Meta may combine information from the Pixel with information it holds about you under its own privacy policy (www.facebook.com/privacy/policy).
3. In the mobile app
The Alex app does not use advertising identifiers, does not track you across other companies' apps or websites, and does not include advertising SDKs. It uses local storage on your device to keep you logged in and remember settings. If you allow notifications, Apple or Google give us a push token so we can send them. You can turn notifications off in your phone's settings.
4. Changes
If we add new non-essential cookies we will update this policy and ask for your consent again.
