Promtact is software you download and run yourself. This page covers the only two places personal data can arise: this website, and writing to us.
The software sends nothing back. There is no telemetry, no phone home, no licence check that transmits usage, and no endpoint here for it to reach. Your seeds, traces, scenarios and measurements stay on your machine.

Website and contact data
promtact.com sets no cookies and runs no analytics. The technical controls that prevent third-party requests are maintained in one place on the Security page.
The hosting provider records ordinary server logs - address, user agent, referrer, time, requested path. These are technically necessary to serve the site and to keep it available. They are not combined with anything else and are not used to build a profile.
| Data | Purpose | Legal basis | Retention |
|---|---|---|---|
| Server logs (address, user agent, referrer, time, path) | Delivering the site, availability and abuse defence | Legitimate interest, Art. 6(1)(f) GDPR | Kept by the hosting provider under its own policy; not retained separately by us |
| Email you send us | Answering you and handling what follows | Legitimate interest, or steps prior to a contract, Art. 6(1)(b) and (f) GDPR | As long as it takes to answer, and any period the law requires |
Sub-processors
| Provider | Purpose | Location | Processing terms |
|---|---|---|---|
| Cloudflare | Static hosting and TLS for promtact.com | Global edge network | DPA |
| Spacemail (Spaceship) | Email for contact@promtact.com | European Union | DPA |
Your rights
Under the revised Swiss Data Protection Act and, where it applies, the GDPR, you may ask what is held about you, ask for it to be corrected or deleted, ask for a copy, and object to processing based on legitimate interest. Write to contact@promtact.com.
You also have the right to complain to a supervisory authority: in Switzerland the Federal Data Protection and Information Commissioner, and in the EU the authority for your country of residence.
