Privacy policy

In short

  • No ads, no analytics, no tracking cookies, no data resale.
  • Your browser never contacts third parties: fonts, logos and article images are served by our own server. The only exception is the Google sign-in reserved for editors.
  • An account only stores what is strictly needed, and you can export or delete it at any time.

Data controller

Maxence Bonnici, publisher of the site (see the legal notice). Contact: the contact form on mbonnici.fr.

Data we process

Without an account, you can read the free edition without providing any personal data. Guest mode (a demo with fictional data) collects nothing either: what you do there stays in your browser.

ProcessingDataLegal basisRetention
Access requestFirst name, last name, email address, language, date of the requestSteps taken at your request before an agreement (GDPR art. 6.1.b)Until the editors answer (the request is then deleted), 30 days at most. If approved, only the email and a username derived from your names are kept in the account.
Reader accountUsername, email address, password (hashed with bcrypt, never stored in clear), chosen portrait, language, role, sign-up and last login datesPerformance of the terms of use (GDPR art. 6.1.b)Until the account is deleted; automatic deletion after 3 years without login
Google sign-in (editors only)Google ID, first name, verified email addressLegitimate interest: securing access to the editor's deskSame as the account
Notifications (optional)Subscription address provided by your browser's notification service, encryption keys, chosen notification types, language; link to your account if signed inConsent (GDPR art. 6.1.a), withdrawable at any time from the bellUntil turned off, or deleted automatically when the browser revokes the subscription
Email exchanges (feedback, forgotten password)Email address and message contentLegitimate interest: answering your requestFor as long as needed, 12 months at most
Clippings and watched coinsReferences of saved articles and coins, title, date savedPerformance of the terms of useUntil removed or the account is deleted
SecurityIP address, kept in memory only to rate-limit login attempts and access requests; a small anti-robot calculation run by your browser (no third-party service, no cookie)Legitimate interest: preventing abuse (GDPR art. 6.1.f)15 minutes to 24 hours, never written to disk

The application does not record IP addresses in its logs. Technical logs (errors, scheduled job status) contain no personal data.

Cookies and local storage

NamePurposeLifetime
kn_sessionHTTP-only cookie: keeps you signed in, or keeps the guest-mode demo session7 days (24 hours in guest mode)
kn_oauthProtects the editors' Google sign-in against request forgery (only created at that moment)10 minutes
kn_localeRemembers the language you chose1 year
kn_currencyRemembers the display currency you chose1 year
kn-guest-v1 (local storage)Guest mode: your clippings, watched coins and demo portrait, kept in this browser only (never sent to our servers, imported into your account if you create one)Until erased from the account page or by your browser
kn-theme (local storage)Remembers the day or night edition (theme)Until your browser clears it

Cloudflare may also set a technical security cookie (for example __cf_bm, 30 minutes) to tell malicious bots apart.

All of these are strictly necessary for the service or remember a choice you made, so they are exempt from consent under French law (article 82 of the Data Protection Act, CNIL guidelines). That is why the site shows no cookie banner.

Recipients and processors

  • Your data is only accessible to the publisher. It is never sold, rented or shared.
  • Cloudflare, Inc. routes traffic (DNS, protection, caching) as a processor. Transfers to the United States rely on the EU–US Data Privacy Framework and standard contractual clauses.
  • Google (Google Ireland Limited), only for editors signing in; Google acts as a separate controller under its own privacy policy.
  • Browser notification services (Google, Mozilla, Apple, Microsoft), if you turn notifications on: they deliver end-to-end encrypted messages that they cannot read.
  • CoinGecko and news publishers are queried by our server, never by your browser, and receive no data about you.

Security

End-to-end HTTPS, passwords hashed with bcrypt, HTTP-only SameSite session cookie, login rate limiting, access requests reviewed by hand and protected against bots, a strict Content Security Policy, a database that is not exposed to the Internet, and a server located in France.

Your rights

You have the right to access, rectify, erase, restrict, object to and port your data, and to set instructions for what happens to it after your death. Most of these rights can be exercised directly from your account: edit your details, download your data as JSON, or permanently delete your account.

For any other request: the contact form on mbonnici.fr. You will get an answer within one month. You can also lodge a complaint with the French data protection authority, the CNIL (cnil.fr).

Minors

Creating an account is reserved for people aged 15 or over.
