Cookies and local storage
Last updated: 9 November 2026
Essential browser storage makes sign-in, preferences and personal progress work.
Essential storage
Session cookies identify your signed-in account. Local storage remembers your daily tools, cookie preference, and an in-progress path-finder draft or an earlier 15-question introduction draft (for up to 24 hours so you can finish signing in by email code or Google without losing your place).
You can clear these in your browser. Doing so may sign you out and remove guest progress that has not been saved to an account.
Optional storage
Optional measurement has three parts: our own anonymous funnel counts, Meta advertising measurement (Meta Pixel and Conversions API), and PostHog product analytics. Meta measurement loads Meta’s script from connect.facebook.net, can set the first-party cookies _fbp and _fbc on dopanudge.com (kept for up to 90 days), and Meta may set its own cookies. PostHog loads through dopanudge.com/rl and stores nothing on your device unless you choose “Accept optional”; after that it may keep a random identifier in local storage and first-party cookies whose names start with ph_ (up to one year). What is sent is described in the Privacy notice.
The anonymous funnel counts are kept on our own servers and use no cookies and no identifiers. “Reject optional” turns all three parts off in this browser and deletes the _fbp, _fbc and ph_ storage we set; a Global Privacy Control signal turns Meta measurement and PostHog off. In the European Economic Area, the United Kingdom, Switzerland and Türkiye, Meta measurement and PostHog start only after “Accept optional”; elsewhere they run until you reject it. Your choice is kept in this browser’s local storage and in a first-party cookie named dopanudge-cookie-choice (one year) so our server can respect it.
