Cookie policy

Effective 20 October 2026 · Nanoforgeflow SAS, Paris

01 What we store

Cookies are small pieces of data a site stores on your device. This policy also covers localStorage, and calls all of it "cookies".

We use two kinds. Strictly necessary ones make the site work and cannot be turned off. Analytics ones stay off until you accept.

No advertising cookies. No cross-site tracking. We do not sell data.

02 Strictly necessary

nff-cookie-consent · localStorage · your consent choice, accepted or declined · until cleared

03 Analytics, with your consent

We use PostHog, hosted in the EU, for product analytics. Requests go through our own domain to PostHog's EU cloud.

Until you accept, it runs without cookies and stores nothing on your device. Visits are told apart by a hash computed on the server that changes every day. It counts page views, clicks, page performance and errors.

If you accept, it stores identifiers to recognise return visits and turns on session replay, with form inputs masked:

ph_* · cookie and localStorage, first-party, set only after accept · return visits and session replay · up to 1 year, or until cleared

04 Consent

On your first visit a consent box appears at the bottom left. Declining and ignoring it have the same effect: analytics stays cookieless.

Your choice is kept in nff-cookie-consent and respected on every later visit.

05 Changing your choice

Use "Cookie preferences" in the footer, or the button below, to reopen the box.

Declining after an accept deletes the PostHog identifiers from your browser and stops session replay. Measurement goes back to cookieless.

Your browser settings can also block or delete cookies and site data.

06 Changes to this policy

We update this policy when our tools or the law change. The date at the top shows the latest version.
