Johan Bretonneau, sole proprietor, publisher of B-NKER, 138 avenue Victor Hugo, 75016 Paris, France, is the data controller. Questions about your data: [email protected].
What we process, why, and for how long

We do no profiling and make no automated decision about you.
Backups. The database is backed up every night, encrypted, at our host OVH. Something deleted or purged can stay in these backups until they expire: 3 days for the copy on the server, up to 6 months for the encrypted archive (7 daily, 4 weekly and 6 monthly copies). Backups are only read to restore the service after an incident.
Who receives your data
Nobody buys it and we do not rent it out. Only our technical providers access it, on our behalf:
- OVH SAS (France): hosting of the site, the API and the database.
- Cloudflare, Inc. (United States): delivery and protection of the site; sees your IP address and requests.
- IONOS SE, Allemagne: contact mailbox.
Transfers outside the EU
Cloudflare processes data in the United States. This transfer relies on the EU-US Data Privacy Framework, which Cloudflare adheres to, and on the European Commission's standard contractual clauses in its data processing agreement. The email sending provider listed above may process your address outside the EU; its data processing agreement includes the European Commission's standard contractual clauses.
Cookies and storage on your device
This site uses no tracker that requires your consent, which is why it shows no cookie banner.
- Your preferences. If you pick a display theme or a time zone, close the alerts bar or sign up for alerts, your browser keeps it in local storage. It is never sent to us.
- Security. Cloudflare may set a technical cookie (such as
__cf_bmorcf_clearance) when it checks that a visit does not come from a bot. - TradingView quotes. Quotes and charts provided by TradingView only load after you click. Once loaded, TradingView Inc. (United States) receives your IP address and may use its own cookies, under its own privacy policy.
- Partner links. When you follow a partner link, you leave B-NKER. The partner may set cookies on its own site to know you came from us; what it collects falls under its own policy. It sends us reports so it can calculate our commissions. On our side, we count outgoing clicks by partner, page, country and day, with no IP address and no identifier.
When advertising arrives. Ads without trackers change nothing. Ads that use cookies or identifiers (targeting, measurement by the ad network) will only be set after you agree, through a banner where "Reject" is as easy as "Accept". This page will then list each ad network and its cookies.
Security
Encrypted connection (HTTPS), administration closed to the public, API keys and confirmation tokens stored as fingerprints only, confirmation tokens single-use and valid for 7 days.
Your rights
You can ask to access, correct, erase or port your data, ask us to restrict its use, and object to any processing based on our legitimate interest. Every alert has a one-click unsubscribe link. Write to [email protected]: we answer within one month.
You can also complain to the French data protection authority, the CNIL (cnil.fr), or to the authority of your own country.
In Switzerland, the Federal Act on Data Protection (FADP) also applies: you have the same rights and can contact the Federal Data Protection and Information Commissioner (edoeb.admin.ch).
Children
