Privacy policy
Last updated: 29 September 2026
Data controller
The data controller is Fluctuatech, 8 rue Michel-Ange, 75016 Paris, France.
No account, no financial data stored
Bridgesheet can be used without creating an account. The assumptions you enter (figures, company names) are sent to the calculation engine solely to produce the requested preview and Excel file. They are processed in memory for the duration of the request and are neither stored nor reused by the publisher.
Audience measurement
The website uses Vercel Web Analytics to measure traffic (page views, country, device type). This tool sets no cookies and uses no persistent identifier: visits are counted in aggregate, without identifying you.
Preferences stored in your browser
Two preferences are stored locally so the website works as expected: your chosen language (NEXT_LOCALE cookie) and the light or dark theme (browser local storage). They are used only for display, are not shared with third parties and do not require consent. You can delete them at any time from your browser settings.
Technical logs
Like any hosting provider, Vercel Inc. records technical logs (IP address, date and time, requested page) to keep the service secure and running. These logs are kept for a limited period, in line with the hosting provider's policy.
Legal bases and transfers
This processing relies on the publisher's legitimate interest in providing a reliable and secure service and measuring its audience. As the hosting provider is based in the United States, technical data may be processed there; such transfers are covered by the safeguards required by the GDPR and described in the hosting provider's privacy policy (https://vercel.com).
Your rights
Under the GDPR you have the rights of access, rectification, erasure, objection, restriction and portability in respect of your personal data. To exercise these rights: contact@bridgesheet.com. You may also lodge a complaint with the French data protection authority, the CNIL (www.cnil.fr), or with your local supervisory authority.
Changes
This policy will be updated when new features (user accounts, saved projects, payments) are introduced. The date of the last update appears at the top of this page.
