Affiliate Disclosure
HealthIndex participates in affiliate marketing programs. This means we may earn commissions on purchases made through our links to retailer sites. This does not affect the price you pay.
Every Type of Data We Collect
The full list. If it is not on this table, we do not collect it.
| Data | Why | Who else sees it | Kept |
|---|---|---|---|
| Email address | Only if you sign up for price alerts | Our email provider, to deliver the alert | Until you ask us to delete it |
| Google account name and email, and the products you save | Only if you sign in, so your watchlist follows you between devices | Google, which handles the sign-in itself | Until you ask us to delete it |
| Pages viewed, referring site, approximate region, device and browser type | Aggregate traffic measurement | Cloudflare Web Analytics, which is cookieless | Aggregate only, never tied to you |
| Which retailer link was clicked, and from which page | To see which comparisons are useful and to attribute commission | The retailer you land on, under its own policy | Not linked to your email or account |
| Server logs, including IP address | To run and secure the site | Our hosting provider | Short-term, per the host's retention |
No passwords, because Google handles sign-in and never shares one with us, and no payment details, because HealthIndex sells nothing directly. We do not sell, rent, or trade any of it.
Deleting Your Data
Stopping the emails. The unsubscribe link in any email marks your subscription inactive. The emails stop right away, but the record stays in our database.
Deleting the record. Email privacy@healthindex.app from the address you signed up with and we will erase it, including any account and saved list. Requests are handled by hand, so allow up to 30 days, and we will confirm once it is done.
Your Rights
You have the right to:
- Access the personal data we hold about you
- Request correction or deletion of your data
- Opt out of newsletter updates at any time
- Disable cookies through your browser settings
