Data we process

1. Server logs

Like any website, our server automatically records, for each request: IP address, date and time, requested page, browser (user agent) and referring page.

Purposes: website security (detecting abuse and attacks), troubleshooting, aggregated traffic statistics.
Legal basis: our legitimate interest in keeping the site secure and working.
Retention: 30 days at most, then automatic deletion.
Location: server hosted by OVH SAS in a data centre in Germany (European Union).

We use no third-party analytics (no Google Analytics) and no analytics cookies.

2. Calculators

Calculations run in your browser. The values you enter are neither sent to us nor stored by us.

3. Emails

If you email us, we use your address and message to reply. Legal basis: legitimate interest. Retention: as long as needed to handle your request, then 12 months at most. Our mailbox is provided by Google (Gmail).

Wisiko is funded by advertising. When advertising is enabled, ads are served by Google AdSense:

Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites.
Google’s use of advertising cookies enables it and its partners to serve ads based on visits to this site and/or other sites on the Internet.
You can opt out of personalised advertising in Google Ads Settings, or opt out of third-party vendors’ use of cookies for personalised advertising at www.aboutads.info or youronlinechoices.eu.
To learn how Google uses data when you use partner sites: How Google uses information from sites or apps that use our services.

Consent. For visitors in the European Economic Area, the UK and Switzerland, no advertising cookies are set without your agreement: a consent message managed by a Google-certified consent management platform (CMP) lets you accept, refuse or customise these cookies and change your choice at any time. If you refuse, non-personalised ads may be shown.

As of the last update, advertising is not yet active on the site and no cookies are set.

Your rights

You have the right to access, rectify, erase, restrict and object to the processing of your data, and to data portability. To exercise them: wisikobot@gmail.com. We reply within one month.

You can also complain to a data protection authority, for example the French CNIL (www.cnil.fr), the UK ICO (ico.org.uk) or the authority in your country.

We will update this page when something changes (for example when advertising is enabled or a new provider is used) and show the date above.
