Privacy Policy

Last updated: 11 May 2026

1. Controller

The controller responsible for data processing on this site is:

Shahad Ishraq
stochas.tech
Großenhainer Straße 74A
01127 Dresden
Germany
Email: admin@stochas.tech

2. Data we collect

2.1 Contact form data

When you submit the contact form on this site, we receive:

This data is sent to our email address (admin@stochas.tech) so we can respond to your inquiry. Form submissions are not stored in an application database; rate-limit counters containing the IP are stored separately in Cloudflare KV for about one hour (see section 4).

Legal basis: Art. 6(1)(b) GDPR (pre-contractual measures at your request — you contacted us to discuss services we may provide).

Providing this data is voluntary. Without name, email, and message we cannot answer your inquiry; that is the only consequence of not providing it.

Retention: As long as the inquiry is relevant to a possible engagement, plus six months. If no engagement results, we delete the email after six months. If we agree on an engagement, contact data is retained per our normal commercial records retention.

2.2 Server access data

When you visit any page on this site, our infrastructure provider (Cloudflare) automatically processes:

This is necessary to deliver the page, maintain security, and detect abuse.

Legal basis: Art. 6(1)(f) GDPR (legitimate interest in operating a stable, secure website).

Retention: short-lived, controlled by Cloudflare. We do not store these logs ourselves.

3. Anti-spam: Cloudflare Turnstile

The contact form uses Cloudflare Turnstile, a CAPTCHA alternative. According to Cloudflare's Turnstile Privacy Addendum, Turnstile collects the visitor's IP address, TLS fingerprint, user agent, the site key and origin, and additional client-side signals from the browser to determine whether the visitor is a human. Turnstile does not use cookies for tracking, does not track users across sites, and is not used for advertising.

Storing or accessing information on the visitor's device for Turnstile is justified under § 25 (2) Nr. 2 TDDDG (formerly TTDSG) as strictly necessary to provide a service the user has explicitly requested (the spam-protected contact form).

Legal basis for processing: Art. 6(1)(f) GDPR (legitimate interest in protecting the form from automated abuse).

4. Rate limiting

Your IP address is briefly stored (less than one hour) in Cloudflare KV to prevent more than a small number of submissions per IP per hour. After one hour the entry is deleted automatically.

Legal basis: Art. 6(1)(f) GDPR (legitimate interest in spam prevention).

5. Recipients of your data (processors)

We use the following processors:

Transfers to the United States rely primarily on the EU-US Data Privacy Framework (Commission adequacy decision of 10 July 2023, currently valid as of May 2026). Where any processor or sub-processor is not certified under the DPF for the relevant processing, transfers are based on EU Standard Contractual Clauses with appropriate supplementary measures.

6. Cookies

This site does not set any cookies of its own and does not use analytics. Cloudflare may set short-lived security cookies if their threat detection requires it.

7. Your rights under GDPR

You have the right to:

To exercise any of these rights, email admin@stochas.tech.
