Privacy Policy
Your privacy is important to us. This policy explains how we collect, use, and protect your information.
1. Data Controller
The data controller responsible for this website is:
Jonas Sebastian SanderArndtstraße 7
23566 Lübeck
Germany
Email: jonas.sander(at)t-online.de
2. Data We Collect
We collect minimal data to provide and improve our service:
2.1 Data You Provide
When you use our tire search functionality, the tire size you enter is sent to our server so that matching tires can be looked up. We do not store these queries in a database and we do not link them to you; because the size is part of the request address, it may appear in the hosting provider's server logs described below.
2.2 Automatically Collected Data
We do not run any analytics, tracking or advertising service on this website. No usage statistics are collected and no visitor profiles are created.
The only data collected automatically is what any web request necessarily involves:
- Server Logs: Our hosting provider records IP addresses, browser type, access times, and requested pages for security and diagnostic purposes. We do not analyze these logs for usage statistics.
- Font Delivery: Our pages load a web font from Google's servers, which requires your browser to send your IP address to Google. See section 5.2.
3. How We Use Your Data
We use collected data for the following purposes:
- To provide and maintain our tire search service
- To detect and prevent technical issues or abuse
- To comply with legal obligations
We do not use your data for profiling, advertising, or usage analysis, and we do not sell or share it with third parties beyond the service providers named in section 5.
4. Legal Basis for Processing (GDPR)
Under the General Data Protection Regulation (GDPR), we process your data based on:
- Legitimate Interest (Art. 6(1)(f) GDPR): For operating and securing the website, including hosting server logs and delivering page assets
- Legal Obligation (Art. 6(1)(c) GDPR): Where required by law
Because we operate no analytics or advertising services, there is currently no processing on this website that relies on your consent.
5. Third-Party Services
We use two third-party services. Neither is used for analytics, tracking or advertising.
5.1 Netlify (Hosting)
Our website is hosted on Netlify. Netlify may collect server logs including IP addresses for security and performance purposes.
More information: Netlify Privacy Policy
5.2 Google Fonts
Our pages use the "Inter" typeface, which is loaded from Google's font servers (fonts.googleapis.com and fonts.gstatic.com). To deliver the font file, your browser connects to Google and Google therefore receives your IP address and the address of the page you are viewing. Google Fonts sets no cookies and is not used to track you across websites.
Google Fonts is operated by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. For transfers to the USA, Google relies on Standard Contractual Clauses approved by the EU Commission.
More information: Google Privacy Policy
6. Cookies and Local Storage
This website sets no cookies. Because nothing here requires consent, there is no cookie banner to click away either.
The site stores a single entry in your browser's local storage, which never leaves your device and is never transmitted to us or to anyone else:
| Name | Purpose | Duration | Provider |
|---|---|---|---|
resultsView |
Remembers whether you prefer search results as a list or a grid | Until you clear it | BikeTireSizer |
You can remove it at any time by clearing site data for this website in your browser
settings. If you visited this site earlier, your browser may still hold a
btf_cookie_consent entry from a consent banner we no longer use; it is unused
and can be cleared the same way.
7. Your Rights Under GDPR
As a data subject in the EU/EEA, you have the following rights:
- Right of Access (Art. 15): Request information about your personal data we process
- Right to Rectification (Art. 16): Request correction of inaccurate data
- Right to Erasure (Art. 17): Request deletion of your data ("right to be forgotten")
- Right to Restrict Processing (Art. 18): Request limitation of data processing
- Right to Data Portability (Art. 20): Receive your data in a portable format
- Right to Object (Art. 21): Object to processing based on legitimate interest
- Right to Withdraw Consent: Withdraw consent at any time without affecting prior processing
To exercise these rights, contact us at: jonas.sander(at)t-online.de
You also have the right to lodge a complaint with a supervisory authority. The competent authority in Germany is the data protection authority of Schleswig-Holstein:
Unabhängiges Landeszentrum für Datenschutz Schleswig-Holstein (ULD)Holstenstraße 98
24103 Kiel
Germany
Website: www.datenschutzzentrum.de
8. Data Retention
We retain data only as long as necessary for the purposes described:
- Analytics data: None is collected, so none is retained
- Server logs: Retained by our hosting provider for its standard log retention period
- Local storage entries: Kept in your browser until you clear them; we never receive them
9. Data Security
We implement appropriate technical and organizational measures to protect your data, including:
- HTTPS encryption for all data in transit
- Regular security updates
- Access controls and authentication
10. International Data Transfers
Our hosting provider (Netlify) and our font provider (Google) are based in the United States, so operating the website involves a transfer of connection data such as your IP address to the US. Those transfers are protected through Standard Contractual Clauses (SCCs) approved by the European Commission, or other legally approved transfer mechanisms.
11. Children's Privacy
Our service is not directed at children under 16. We do not knowingly collect personal data from children. If you believe we have collected data from a child, please contact us immediately.
12. Changes to This Policy
We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
