Privacy Policy
Last updated: April 21, 2026The short version: Grey Peptides does not require accounts, does not collect personal information, and does not sell data to anyone. We use Google Analytics for aggregate traffic insights and load fonts from Google. That's it.
1. Who we are
Grey Peptides (greypeptides.com) is an independent educational website that publishes peptide research, reference tools, and informational articles. We do not sell peptides, supplements, or any physical products. We are not a medical provider.
2. What we collect
Grey Peptides is designed to collect as little data as possible. Here is a complete summary of the information that may be gathered when you visit the site:
| Data type | Collected by | Purpose |

| Anonymized page views, session duration, referral source, general geographic region, device type, and browser type | Google Analytics | Understanding which content is useful and how visitors find the site |
| IP address (transient) | Netlify (hosting), Google Fonts | Serving web pages and font files — standard web hosting operations |
No data in the table above is linked to your name, email, or any personally identifiable information. We do not combine analytics data with any other data source.
3. What we don't collect
To be explicit about what Grey Peptides does not do:
We do not require or offer user accounts, logins, or registrations. We do not collect names, email addresses, phone numbers, or mailing addresses. We do not store payment or credit card information. We do not operate contact forms, comment sections, or user-submitted content features. We do not track individual users across sessions. We do not sell, rent, or share any data with third parties for marketing purposes. We do not build user profiles or create advertising segments. We do not use fingerprinting or cross-site tracking technologies.
4. Analytics
We use Google Analytics (measurement ID: G-DH5ZM9H10Y) to understand aggregate traffic patterns — which pages are visited, how visitors arrive at the site, and what content is most useful. Google Analytics uses cookies to distinguish unique visitors.
Google processes this data under its own privacy policy. We have configured Google Analytics to anonymize IP addresses where supported. We do not enable advertising features, remarketing, or demographic reporting within Google Analytics.
You can opt out of Google Analytics entirely by installing the Google Analytics Opt-out Browser Add-on, or by using a browser extension that blocks tracking scripts.
5. Cookies
Grey Peptides does not set its own cookies. Google Analytics may set the following cookies:
| Cookie | Purpose | Duration |
|---|---|---|
_ga |
Distinguishes unique visitors | 2 years |
_ga_* |
Maintains session state | 2 years |
These cookies can be blocked in your browser settings or with any standard ad-blocker without affecting site functionality. Every tool, article, and page on Grey Peptides works fully without cookies.
6. Third-party services
The site uses a small number of external services to function. Each is listed here with a link to its privacy policy:
| Service | What it does | Privacy policy |
|---|---|---|
| Netlify | Hosts the website and serves pages to your browser | netlify.com/privacy |
| Google Analytics | Provides anonymized traffic analytics | policies.google.com/privacy |
| Google Fonts | Delivers the typefaces used on the site (Instrument Serif, DM Sans, Fira Code) | policies.google.com/privacy |
We do not use social media tracking pixels, embedded social widgets, or third-party comment systems.
7. Affiliate links & advertising
Grey Peptides may display advertisements or include affiliate links in its content. When present, affiliate relationships are disclosed inline. Clicking an affiliate link may allow the affiliate partner to set cookies or record a referral on their own domain.
Affiliate relationships have no influence on editorial content. Evidence grading, regulatory status reporting, and clinical assessments are entirely independent of any commercial relationship.
8. Data retention
Google Analytics data is retained for 14 months, after which it is automatically deleted. Because we do not collect personal information, there is no personal data to retain or delete on our end.
9. Your rights
Depending on where you are located, you may have rights under data protection laws such as the GDPR (European Union), UK GDPR, CCPA (California), or similar regulations. These typically include the right to access data held about you, request deletion of your data, opt out of data collection, and object to data processing.
Because Grey Peptides does not collect personally identifiable information, there is generally no personal data for us to provide, correct, or delete. However, if you have questions about data associated with your visit, you are welcome to contact us.
California residents (CCPA): We do not sell personal information. We do not share personal information for cross-context behavioral advertising.
EU/UK visitors (GDPR): The lawful basis for processing analytics data is legitimate interest in understanding aggregate site usage. You may opt out at any time using the methods described in the Analytics section above.
10. Children's privacy
Grey Peptides is not directed at individuals under the age of 18. We do not knowingly collect any data from children. The site's content covers biomedical research and pharmacological information intended for an adult audience.
