Cookie Policy
Last updated · August 29, 2026
This page lists every entry SupplementPrices writes to your device, what each one is for, and how long it lasts. There are three of them, and two only exist because you were asked a question.
Your current choice
Rejecting stops the analytics SDK and deletes what it stored. Nothing else on the site changes: every price, filter, country and ranking works exactly the same either way.
1. What cookies and local storage are
A cookie is a small text file a website stores on your device. Local storage (also called Web Storage) is a similar browser mechanism for keeping data locally. Both fall under the same rules — Section 25 TDDDG and the GDPR — so both are listed here.
2. What we store
| Name | Type | Purpose | Duration | Party | Category |
|---|---|---|---|---|---|
sp_consent | Cookie | Remembers whether you accepted or rejected analytics, so the banner asks once and then honours the answer across pages and visits. | 12 months | First-party | Strictly necessary |
ph_<project-key>_posthog | Cookie + local storage | PostHog analytics: a randomly generated device identifier, the current session identifier, and the referrer and campaign values the visit started with. It holds no name, email address or account — there are none on this site. | 12 months | First-party (served through /px on this domain) | Analytics — consent required |
__ph_opt_in_out_<project-key> | Cookie | Written by the analytics SDK at the moment you withdraw consent, to switch capturing off. We delete it again immediately afterwards, together with the entry above. | Momentary | First-party | Strictly necessary |
The analytics entries are written only after you press “Allow analytics”. Before that, the SDK is not started at all — it is not loaded and silenced, it simply never runs. If this deployment has no analytics key configured, none of them ever appear.
3. Legal basis
sp_consent is strictly necessary under Section 25(2) No. 2 TDDDG, with Art. 6(1)(f) GDPR as its basis: remembering your answer is the only way to respect it. The analytics entries require your consent under Section 25(1) TDDDG and Art. 6(1)(a) GDPR. Withdrawal takes effect for the future and does not affect processing that was lawful before it.
4. What we do not use
- No advertising network, retargeting pixel or cross-site behavioural profile
- No third-party cookies — the analytics endpoint is proxied through our own domain
- No fingerprinting, session recording, heatmaps or scroll tracking
- No social-media plugins, embedded fonts loaded from third parties, or hidden trackers
- No cookie stuffing: affiliate tags travel in the outbound link itself and are stored nowhere
- No data sold or shared for anyone else’s purposes
5. Amazon’s cookies
When you follow a product link you leave this site. Amazon then sets its own cookies under its own cookie notice, including the ones that attribute a purchase to our Associates tag. We neither set nor read those cookies, and this page has no control over them. See the Privacy Policy for what that means.
6. Changing your mind, from the browser
Besides the button above, you can clear stored cookies and local storage at any time, which also resets the banner on your next visit:
- Chrome: Settings → Privacy and security → Delete browsing data
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Clear Data
- Safari: Settings → Privacy → Manage Website Data
- Edge: Settings → Cookies and site permissions → Manage and delete cookies and site data
Blocking storage entirely still leaves the site fully usable — you will simply be asked again on each visit, because there is nowhere to record that you said no.
