Privacy policy

Pavel Tsiber, sole trader (OSVČ), IČO 19222912, Na Hvížďalce 1662/13, Stodůlky, 155 00 Praha 5, Czechia. Questions and requests: pavel@tsiber.com.

The callback request

Your name, your phone number and whatever you wrote. They are there so that I can call back and answer; the basis is your own request.

The form is taken by Web3Forms, which passes it on by e-mail to my Google Workspace mailbox. Web3Forms keeps the request for up to three years and deletes it automatically; it may pass your IP address to anti-spam services; the data leaves the EEA under standard contractual clauses. In my mailbox the request lives while the conversation lasts, and a year after.

Visits to the site

Google Analytics 4 through Google Tag Manager — only if you agreed in the banner. Events are kept for two months, data about the visitor for fourteen. There are no advertising pixels on this site.

Running the site

Hosting is DigitalOcean. Server logs hold the IP address, the time and the address of the page; without them the site is neither served nor defended.

Who else sees it

Google (mail, analytics, tag manager), Web3Forms (form intake), CookieYes (consent banner), DigitalOcean (hosting). No one else, and not for money.

Your rights

To know what is held about you; to correct it; to erase it; to restrict the processing; to object; to get a copy; to withdraw consent. Write to pavel@tsiber.com — I answer within a month.

If the answer does not settle it, the complaint goes to Úřad pro ochranu osobních údajů, Pplk. Sochora 27, 170 00 Praha 7.
