1. Data Controller
Fermentation Tools (https://fermentationtools.net) is operated by an individual based in France. For any privacy-related questions, you can reach us at privacy@fermentationtools.net.
2. What Data We Collect
We are committed to minimal data collection. Here is what we process:
2.1 Language Preference Cookie
We store a single functional cookie to remember your preferred language across visits. This cookie contains only a language code (e.g., "en", "fr") and is strictly necessary for the site to function as expected. It does not track you or contain any personal identifier.
2.2 Server Access Logs
Like virtually all web servers, our hosting infrastructure automatically records standard access logs, which may include:
- Your IP address
- Date and time of access
- Pages requested (URL)
- HTTP status code
- User agent string (browser and operating system information)
- Referrer URL
These logs are used solely for security monitoring, error diagnosis, and abuse prevention. They are stored for 30 days and then automatically deleted.
2.3 What We Do NOT Collect
We want to be explicit about what we do not do:
- We do not use Google Analytics or any other analytics service
- We do not use tracking cookies or advertising cookies
- We do not use Facebook Pixel, Google Ads, or any third-party tracking scripts
- We do not create user profiles or fingerprint devices
- We do not sell, share, or transfer any data to third parties for marketing purposes
3. Amazon Affiliate Links
This site participates in the Amazon Associates affiliate program. Some links on our pages lead to products on Amazon. When you click an affiliate link, you leave our site and are redirected to Amazon.com (or a local Amazon storefront). Once on Amazon, Amazon's own privacy policy applies. We have no control over the cookies or tracking that Amazon uses on their platform.
We may earn a commission from qualifying purchases made through these links, at no additional cost to you. The affiliate link itself does not send us any of your personal data.
4. Legal Basis for Processing
Under the GDPR (General Data Protection Regulation), our legal bases for processing are:
- Legitimate interest (Art. 6(1)(f) GDPR) for server access logs, which are necessary for security and the proper operation of the site.
- Exemption under ePrivacy Directive (Art. 5(3)) for the language preference cookie, which is strictly necessary for a functionality explicitly requested by the user.
5. Data Retention
| Data type | Retention period |
|---|---|
| Server access logs | 30 days |
| Language preference cookie | 1 year (stored in your browser) |
