Legal & Privacy

Privacy Policy

This Privacy Policy explains how RestoCalculator may collect, use, store and protect information when you use the website and its calculators.

RestoCalculator provides free restaurant calculators and related resources. The specific information involved depends on how you interact with the website — for example, using a calculator or emailing us — and is described section by section below.

What we collect

Information We Collect

Information You Provide

RestoCalculator has no contact form and no other form that visitors can submit. Our contact page simply publishes an email address, so if you get in touch you do so from your own email account and your message never passes through this website. We then hold whatever you chose to put in that email — typically your name, your email address and the content of your message — in our mailbox, and use it only to reply to you. RestoCalculator does not otherwise ask visitors to submit personal information, and there is no account system to sign up for.

Information Collected Automatically

Like most websites, the servers and hosting infrastructure that deliver RestoCalculator may automatically record standard technical information with each request, such as IP address, browser and device type, the pages requested, referring pages and the date and time of the request. This is a routine function of web server software rather than a purpose-built tracking system, and RestoCalculator does not currently combine this information with any analytics or advertising service.

Calculator Information

Details on the values you enter into a calculator are covered separately below in Calculator Data.

Purpose

How We Use Information

Where any of the information above applies to your visit, RestoCalculator uses it only for purposes such as:

Operating the Website

Delivering pages and calculators and keeping the site running correctly. Legal basis: our legitimate interest in operating the website (Art. 6(1)(f) GDPR).

Responding to Inquiries

If you email us, we use the information in your message to reply to you. Legal basis: our legitimate interest in answering the messages we receive (Art. 6(1)(f) GDPR).

Security and Troubleshooting

Basic technical request data can help identify errors, abuse or misuse of the website. Legal basis: our legitimate interest in keeping the website secure (Art. 6(1)(f) GDPR).

Legal Compliance

Where applicable, to meet legal or regulatory obligations that apply to the website. Legal basis: compliance with a legal obligation (Art. 6(1)(c) GDPR).

RestoCalculator does not use information collected through the website for personalized advertising or profiling, and does not sell personal information.

The numbers you enter

Calculator Data

Every RestoCalculator tool — including the Food Cost, Menu Price, Restaurant Profit, Break-Even, Labor Cost, Tip and Table Capacity calculators — runs entirely in your browser. The values you type into a calculator are processed on your device with JavaScript to produce the displayed result.

Calculator inputs are not sent to a RestoCalculator server, are not stored in a database or user account, and are not saved in your browser’s local or session storage. Once you close or refresh the page, the values and result are gone. Standard web server request logging as described in Information We Collect may still apply to the page request itself, but not to the numbers you enter into a calculator.

Cookies & storage

Cookies and Similar Technologies

RestoCalculator does not currently set analytics cookies, advertising cookies or any other tracking cookies, and the website does not use a cookie consent tool because no such cookies are in use. There is no comment system and no visitor account area that would otherwise set cookies. The website runs on WordPress, whose administration and sign-in screens (/wp-admin/ and /wp-login.php) are reachable on the public internet as part of that software; they exist for the site owner rather than for visitors, and WordPress sets cookies there only for someone who actually attempts to sign in.

The calculators do not use browser local storage or session storage to save the values you enter — see Calculator Data. Fonts, scripts and styles are all served from our own hosting, so the website loads no outside resource that would involve a request to a third-party server.

If this changes — for example, if we later add analytics, advertising or a cookie consent tool — this section will be updated to describe it accurately.

Who we rely on

Third-Party Services

RestoCalculator keeps the number of third-party services to a minimum. The website’s fonts (Bricolage Grotesque and Inter), scripts and styles are all self-hosted, so your browser does not contact any third-party server while you browse. At the time of writing, the only service provider involved in running the website is:

LWS (hosting)

The website is hosted by LWS (Ligne Web Services), 10 rue Penthièvre, 75008 Paris, France, on servers located in France. As our hosting provider, LWS processes the technical server-log data described in Information We Collect on our behalf. No personal data is transferred outside the European Union by the website.

RestoCalculator does not currently use analytics, advertising, payment processing, visitor authentication or any form-handling service — there is no form on the website to handle. If a new third-party service is added to the website, this section will be updated to name it and explain what it does.

How long

Data Retention

Because RestoCalculator does not operate a user account system and does not store calculator inputs, there is generally no personal data of that kind for us to retain. Standard technical server-log data referenced in Information We Collect is retained by our hosting infrastructure for a limited operational period, in line with our hosting provider’s own practices.

If you email RestoCalculator, we may keep that correspondence in our mailbox for as long as reasonably necessary to respond to and manage your inquiry.

Keeping things reasonable

Data Security

We take reasonable measures designed to help protect information processed through the website, such as serving the site over HTTPS. No method of transmission or storage over the internet is completely secure, and RestoCalculator cannot guarantee absolute security.

Your choices

Your Privacy Choices and Rights

RestoCalculator is published from France, so the processing described in this policy is governed by the EU General Data Protection Regulation (GDPR) and the French Data Protection Act (Loi Informatique et Libertés). The data controller is Hugo Dufour, 27530 Ézy-sur-Eure, France.

Under these laws, you have the right to access, rectify and erase personal data relating to you, to restrict or object to its processing, and to data portability where applicable. You may also give instructions on what should happen to your data after your death.

If you believe your data has not been handled in line with these laws, you have the right to lodge a complaint with the French data protection authority, the CNIL (Commission Nationale de l’Informatique et des Libertés, 3 place de Fontenoy, TSA 80715, 75334 Paris Cedex 07 — www.cnil.fr), or with the supervisory authority of the EU country where you live.

To ask a question about this policy or to make a request about information relating to you, email contact@restocalculator.com. Because RestoCalculator does not maintain visitor accounts, does not store calculator data and operates no contact form, most requests will primarily concern the limited technical and correspondence information described above.

General audience

Children’s Privacy

RestoCalculator is intended for a general, professional audience — such as restaurant owners, operators and chefs — and is not specifically directed to children. The website does not knowingly collect personal information from children, and does not include an age-verification system.

Staying current

Changes to This Privacy Policy

We may update this Privacy Policy when our website, services or legal obligations change. The updated version will be posted on this page with a revised “Last updated” date. We do not currently notify visitors of changes individually, since there is no account or subscription system through which to do so.
