# Cookie Policy

Version 2.0 · Last updated 4 October 2026

This policy explains how the Vitality Tracker **website and web app** at vitalitytracker.app use cookies and similar technologies (such as your browser's local storage), and what you can choose. The **mobile app** is covered at the end.

## 1. What we use

### Essential (always on)

Needed for the website to work — signing you in and remembering your choices:

| Name | What it does |
| --- | --- |
| `sb-…-auth-token` (local storage) | Keeps you signed in (Supabase) |
| `cookie-consent` (local storage) | Remembers your cookie choices |

### Analytics (optional)

Help us understand how the website is used, so we can improve it:

| Name | Provider | What it does |
| --- | --- | --- |
| `_ga`, `_ga_*` | Google Analytics, via Google Tag Manager | Counts visits and how pages are used |
| `_gid` | Google Analytics | Tells visits apart over a day |
| Firebase Analytics storage | Google Firebase | Counts how features are used |

### Marketing (optional)

Measure our advertising. They are only set if you accept marketing cookies, and **never receive any health information**:

| Name | Provider | What it does |
| --- | --- | --- |
| `_fbp` | Meta (Facebook) Pixel | Measures visits that come from our Facebook and Instagram ads |
| `_ttp` | TikTok Pixel | Measures visits that come from our TikTok ads |

### Support and reliability

| Provider | What it does |
| --- | --- |
| Help Scout (Beacon) | The support chat window; sets cookies to keep your conversation |
| Sentry | Reports errors and crashes so we can fix them; records technical details of the error, not your health data |

## 2. Your choices

When you first visit, a banner asks you to choose:

- **Essential only** — only what the website needs to work.
- **Accept all** — essential, analytics and marketing.

You can change your choice at any time from the **Cookie Policy** link in the footer. When you opt out, we remove the optional cookies we set. You can also block or delete cookies in your browser settings; the website may not work properly without the essential ones.

## 3. The mobile app

The Vitality Tracker app does **not** use cookies. It keeps your sign-in, settings and the data it shows you in your phone's own storage, and the access keys for connected services in your phone's secure storage (Keychain on iPhone). The app has **no advertising or analytics trackers** and does not track you across other companies' apps or websites.

## 4. Changes

If we add or change cookies, we will update this policy and, where your choice is needed, ask you again.
