Privacy policy

Translation provided for information: only the French version is legally binding.

In brief. This website does not track your browsing and shows no advertising; it sets only one cookie, and only if you choose a language from the list at the bottom of the page. I receive only what you write in the forms (quote, ChaiTrace trial or subscription) and, if you use ChaiTrace, the small amount of technical data used to check its access key. Your cellar data stays on your computer.

1. Data controller

Lubin Rocher, sole trader (Studio LR), 4 rue Pardessus, 41000 Blois, SIREN 130 711 146. Contact: lubin.rocher@studio-lr.fr.

2. The quote form

• Data: your name, your email address and, if you provide them, your phone number, your business, your needs and your message, as well as the language of the page.
• Purpose: to answer your request and, if you wish, to draw up a quote.
• Legal basis: pre-contractual measures taken at your request (Article 6(1)(b) GDPR) and, for a simple exchange, my legitimate interest in answering the messages I receive (Article 6(1)(f)).
• Retention period: three years after our last exchange if no contract is concluded; if you place an order, accounting records are kept for ten years (article L.123-22 of the French Commercial Code).
• Recipients: myself and, if your project involves him, Mathis Soupizon, partner developer. Your data is not sold, rented or passed on to third parties, apart from the website's host and my email provider, which process it on my behalf.

3. The ChaiTrace trial and subscription

• Data: your name, your email address, the plan chosen and the date on which you accepted the terms and, if you provide them, the name of your estate, your phone number and your message. For a subscription, your billing details are added.
• Purposes: to send you the software and your access key, and to manage the trial, the subscription, billing and support.
• Legal basis: performance of the contract (Article 6(1)(b) GDPR) and, for invoices, my accounting obligations (Article 6(1)(c)).
• Retention period: three years after our last exchange if the trial is not followed by a subscription; otherwise, for the duration of the subscription and then five years after it ends (limitation period); accounting records are kept for ten years (article L.123-22 of the French Commercial Code).
• Online sales: these are handled by Link, Stripe's payment service, which acts as reseller. Link receives your name, your email, your billing address and your payment details, and processes them as data controller, under its privacy policy. I receive from Stripe your name, your email, the name of your estate and the last four digits of your card.

4. The ChaiTrace access key

ChaiTrace runs on your computer, and your cellar data stays there: I have no access to it and receive no copy of it. Only the access key is checked online, on activation and then about once a day when the computer is connected.

• Data: the name of the key holder, the key itself, a technical fingerprint of the installation, and the dates of activation and verification. The fingerprint is a hash calculated from the name of the computer and of the Windows user account: these names are not transmitted in plain text.
• Purposes: to issue and verify the licence, to limit each key to one installation, and to prevent fraud.
• Legal basis: performance of the licence agreement (Article 6(1)(b) GDPR) and my legitimate interest in protecting the software (Article 6(1)(f)).
• Retention period: for the duration of the trial or subscription, then five years after it ends.
• Processor: the verification service runs on the infrastructure of Cloudflare, Inc. (United States). This transfer is governed by the EU–US Data Privacy Framework, under which Cloudflare is certified, and by the European Commission's standard contractual clauses. Cloudflare may temporarily record the connecting IP address for the security of its network.
• Updates: twice a day, the software also reads the number of its latest version on studio-lr.fr, to let you know about an update. It sends no data; as for any page of the website, the host may log the connecting IP address (section 5).

5. Technical logs

Like any host, the website's host (IONOS SARL, see the legal notice) may record technical connection data, such as the IP address and the pages requested, for the security and proper operation of the service.

6. The website's language

With every page, your browser indicates the languages you prefer. The server uses this to show you the page directly in your language; nothing is recorded. If you choose a language from the list at the bottom of the page, a cookie named “langue” remembers this choice for one year, on your device. It is used only for this and is read only by this website: as it is essential to the service you request, it does not require your consent.

7. Font

The website's font, Archivo, is loaded from the Google Fonts servers (Google Ireland Limited). To do this, your browser sends your IP address to Google. No cookie is set in the process.

8. Your rights

You have the right to access, rectify, erase, restrict, object to and port your data, as well as the right to set instructions on what happens to it after your death. To exercise these rights, write to lubin.rocher@studio-lr.fr; I reply within one month. If you believe your rights are not being respected, you can lodge a complaint with the CNIL, the French data protection authority (www.cnil.fr).

9. Security

The website is served over HTTPS: form data is encrypted between your browser and the server. Exchanges between ChaiTrace and the key verification service are encrypted too.
