Privacy

1. Controller

The party responsible for data processing on this website is:

Roberto Di Sisto
Leverkuser Straße 20
40591 Düsseldorf
Deutschland

2. Hosting and server log files

When you access this website, information transmitted by your browser is automatically stored in server log files: IP address, date and time of the request, the page requested, the HTTP status code and the user agent. This processing serves to ensure trouble-free operation and security on the basis of Art. 6(1)(f) GDPR (legitimate interest). Log data is deleted after 30 days at the latest, unless it is needed to investigate a security incident.

3. Cookies

This website uses strictly necessary cookies, plus, only if you opt in, one cookie that remembers your analytics choice. There is no third-party tracking. Analytics (Matomo, see section 7) stays off until you accept it via the consent banner.

PHPSESSID: session cookie protecting forms (CSRF protection). Deleted when the browser is closed.
analytics_consent: remembers whether you accepted or declined analytics. Set only after you choose; lifetime 1 year.

Local storage

The site uses your browser's local storage (not cookies) to remember UI preferences. This data never leaves your device.

sidebarCollapsed: whether the sidebar is collapsed or expanded.
cat-*: sidebar category expand/collapse states.

4. Tool data processing

Every tool page carries a processing badge so you always know how your input is handled.

Client-side tools run entirely in your browser. No data is sent to any server. The source code is auditable in your browser's developer tools.
Server-side and Network query tools send your input to the server for processing. Input data is not stored, logged or shared beyond what is needed to produce the result.
External API tools query third-party services. Requests are proxied through the server; the external service sees the server's IP address, not yours.

5. Contact form

If you use the contact form, the data you provide (name, email address, subject, message) and your IP address are processed in order to answer your enquiry. The submission is sent by email to the controller. The legal basis is Art. 6(1)(a) and (f) GDPR. The data is deleted once your enquiry has been dealt with, unless statutory retention obligations apply.

6. Third parties

Tools that query external APIs do so through the server. The external service only sees the server's IP address, not yours. Only the minimal required data is transmitted (e.g. a domain name for DNS lookup). There are no advertising networks, no social plugins and no profiling.

7. Analytics (Matomo)

This site uses Matomo, an open-source analytics tool hosted on its own infrastructure. Analytics is opt-in: nothing is measured unless you accept via the consent banner.

Self-hosted on own servers (no data sharing with third parties)
Your IP address is processed for geolocation and stored only on own servers (never shared with third parties)
Respects the browser "Do Not Track" setting
Server-side measurement; no cookie is used to recognise you across visits
You can withdraw your consent at any time using the links below

The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time with effect for the future.

Manage your choice: accept analytics · decline analytics.

8. Your rights

You have the right of access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and objection (Art. 21) under the GDPR. To exercise these rights, contact supporttroubleshooting.tools.

You also have the right to lodge a complaint with a supervisory authority.

9. Status

This privacy policy is updated as needed to reflect changes to the website or the legal situation.
