fluah.com's cookies

Each is set only when you log in or start to. Each is HttpOnly (no script can read it), Secure (sent only over HTTPS) and kept to fluah.com: no other site, docs.fluah.com included, ever receives it. docs.fluah.com sets no cookies of its own.

CookieWhat it doesHow long
__Host-fluah_sessionKeeps you logged inUntil you close the browserWith Keep me logged in: until you log out, 30 days at most
__Host-fluah_deviceRemembers a browser that entered an emailed code, so it is not asked for one every timeUntil you close the browserWith Keep me logged in: 30 days, or until you log out
__Host-fluah_flowHolds a log-in step under way: the emailed code, or a new account through Google, Microsoft or Apple30 minutes
__Host-fluah_oauthHolds a sign-in with Google, Microsoft or Apple while it is under way10 minutes

The payment page

Buying Fluah Pro at fluah.com/account/purchase loads Stripe's card form, the only page that does. Stripe sets two cookies there to stop card fraud.

CookieWhat it doesHow long
__stripe_midStripe: recognises a browser across payments, to spot fraud1 year
__stripe_sidStripe: the same, for one visit30 minutes

Stripe's card form runs in Stripe's own frames. They keep a cookie on Stripe's domain (m, 2 years) and can run an hCaptcha check against card testing. Both fall under Stripe's cookie policy.

Cloudflare

fluah.com and docs.fluah.com reach you through Cloudflare, which shields them from attacks. Today Cloudflare sets no cookies on either. If it ever has to check that a visit comes from a person, it can set these.

CookieWhat it doesHow long
__cf_bmCloudflare: tells people from automated traffic30 minutes
cf_clearanceCloudflare: remembers that a visit passed its check30 minutes

Cloudflare lists every cookie it can set on its cookies page.

In your browser

A few small notes stay in your browser's own storage. None of them leaves your computer.

NameWhat it doesHow long
fluah.periodMonthly or Yearly, as you picked it on Pricing or PlanUntil the tab closes

Browser check at log in. When you log in, the page turns your browser's details (browser, language, screen size, time zone) into a one-way code and sends it with your password or emailed code. It is used only to recognise a browser you have already checked and to spot unusual log-ins, never for advertising.

What we don't do

  • No analytics: no Google Analytics or anything like it
  • No advertising, retargeting or social media pixels
  • No fonts, videos or scripts from other sites, apart from Stripe's card form
  • No selling or sharing of what a cookie holds

Your choices

Leave Keep me logged in unticked when you log in, and closing the browser logs you out. Block or delete cookies in your browser's settings at any time: every page still reads without them; logging in and paying need them. As every cookie here is essential, there is nothing else to switch off on this site.

Changes and contact

If fluah.com ever needs a cookie that is not essential, we will update this page first and ask you before it is set.

fluah.com is run by Thessova. Questions: [email protected]. Our Privacy Policy covers the rest.
