This policy explains how the Vitality Tracker website at vitalitytracker.app and the web 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

Analytics (optional)
Only if you choose Accept all. They help us understand how the website and web app are used, so we can improve them:
| Name | Where | What it does |
|---|---|---|
_ga, _ga_… (Google Analytics) | Website and web app | Counts visits and how pages are used |
| Firebase storage (Google Firebase Analytics and Performance Monitoring) | Web app | Counts how features are used and how quickly pages load |
Marketing
We do not use marketing or advertising cookies. If we add any, we will update this policy and ask you first.
Support and reliability
| Provider | Where | What it does |
|---|---|---|
| Cloudflare Turnstile | Website | Checks that a form is sent by a person, not a bot |
| Help Scout (Beacon) | Web app | The support chat window; sets cookies to keep your conversation |
| Sentry | Web app | 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 or web app needs to work.
- Accept all — essential and analytics.
You can change your choice at any time. On the website, change your cookie choice here; this page is always linked from the footer as Cookie Policy. In the web app, use its own Cookie Policy page. 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.
