Personal data

Data controller

Data I Know (contact details above). For any question about your data: contact@dataiknow.com.

Data collected and use

The site collects personal data only through the form: name, company, email address, telephone number (optional), the area and the description of your problem, together with the selection you attach to it, as well as the language and the page from which you are writing. This information is used solely to answer your request and, if you so wish, to send you a proposal. It is not sold, rented or transferred, and is not used for any automated direct marketing.

Legal basis: your consent, given by ticking the box on the form, and pre-contractual measures taken at your request (Article 6(1)(a) and (b) GDPR).

Candidates

The “Offer my skill” form collects your first and last name, email, occupation, country, region and an optional message, to offer you introductions to organisations looking for your skill; your profile is only introduced with your consent, each time. Legal basis, recipients, retention (2 years after our last exchange) and rights: see the Candidates section of our terms.

File upload through a personal link

At Data I Know’s invitation, you may upload files (csv, txt, tsv, xlsx, xml) from a page reachable only through a personal, temporary link. The link is valid for 30 days at most (7 days by default) and can be revoked at any time; the page is not indexed by search engines. Each file is encrypted as soon as it is received, with a key held only by Data I Know’s internal tool: the host cannot read it. That tool collects the files and then has them deleted from the site; a file that has not been collected is deleted when the link expires at the latest. We keep only the link’s fingerprint, and a request counter per IP-address fingerprint limits abuse. The files are processed for your engagement, as a processor, and kept for 90 days after delivery (terms, sections 8 and 10). This page uses no cookie. For any question: contact@dataiknow.com.

Recipients

Your request arrives by email in Data I Know’s mailbox and is read only by Data I Know. When Data I Know’s internal request-tracking tool is in service, an encrypted copy of the request is also deposited on the site’s hosting, unreadable without that tool’s key; the tool, hosted in the European Union, collects it and then has it deleted. OVH SAS, host of the site and of the email service, acts as technical processor, in France. No data is transferred outside the European Union.

Retention period

Your data is kept for as long as it takes to process your request. If a business relationship is entered into, it is kept for the duration of that relationship, then for the periods required by law (accounting records: 10 years). If no business follows, it is deleted no later than 3 years after our last exchange.

Your rights

You may at any time access your data, have it rectified or erased, restrict its use, object to it, request its portability, and withdraw your consent: write to contact@dataiknow.com. We reply within one month. If you consider that your rights are not being respected, you may lodge a complaint with the CNIL (Commission nationale de l’informatique et des libertés, the French data protection authority) (cnil.fr).

Cookies and trackers

The site uses no cookies whatsoever, neither advertising nor audience measurement cookies, and loads no third-party service (the fonts are hosted on the site). It only stores, in your browser, the language you have chosen and what you keep in order to take stock (questions and resources): the content of your selection reaches us only if you submit the form. The selection clears itself after 90 days without any change. You can also clear it with the “Clear my selection” button or by clearing the site data in your browser.

To improve the site and our answers, we anonymously count certain actions: a question or resource kept, a facet or family opened, the number of situations attached to a request (for example, “a given question was kept 40 times this month”). This count uses neither cookies nor identifiers and does not record your IP address. To avoid counting the same action twice, the server generates a temporary fingerprint using a key renewed every hour; once the key has been replaced, this fingerprint can no longer be traced back to the address. Only the monthly totals are kept, on our hosting, in France.

Legal basis for this count: our legitimate interest in knowing how the site is used in order to improve it (Article 6(1)(f) GDPR). It places no cookie, reads nothing in your browser, does not keep your IP address and is used only for anonymous statistics; it therefore does not require your consent. You may nevertheless object to it by writing to contact@dataiknow.com.

Security

Exchanges with the site are encrypted (HTTPS). To limit automated submissions, the server counts form submissions per IP address for one hour, in the form of a fingerprint obtained with a key renewed every hour: once the key has been replaced, the fingerprint can no longer be used to recover the address, and records older than one hour are deleted. In addition, for the security of its servers, the host keeps technical connection logs in accordance with its own rules.

Intellectual property
