Cookie Policy
Version 1.0 · Effective August 23, 2026 · Last updated August 23, 2026
What we use
This list is taken from the application code, not from a template. BestExperimentIdeas does not use advertising cookies, cross-site tracking pixels or third-party marketing tags.
| What | Stored as | Purpose |
|---|---|---|
| Authentication session | Cookie and localStorage (set by our backend auth provider) | Keeps you signed in and lets the app call the backend as you. Without it you cannot stay logged in. |
| Local project drafts | localStorage | Saves a project draft you started before signing in, and remembers wizard progress so you do not lose work on refresh. |
| Assistant change tracking | localStorage | Remembers which assistant suggestions you have already reviewed for a project. |
| Referral and attribution | localStorage and sessionStorage | Records the referral code or source you arrived from so a referral can be credited once, and prevents a click being counted twice in a session. |
| Analytics events | sessionStorage | De-duplicates product analytics events (for example counting one project view per session). |
| Error-recovery flag | sessionStorage | Prevents an endless reload loop if the app fails to load once. |
| Stripe checkout | Cookies set by Stripe during checkout | Runs the embedded payment form and Stripe's own fraud prevention. Set only when a checkout or billing page is opened. |
| Google sign-in | Cookies set by Google on Google's domains | Used only if you choose 'Continue with Google', to complete the sign-in. |
| YouTube embeds | Cookies set by YouTube | Set by YouTube when a project page contains an embedded video you play. Governed by YouTube's own policies. |
Necessary versus optional
- Necessary: authentication, local drafts, error recovery, and the cookies Stripe sets during checkout. The site cannot work without these.
- Functional: assistant change tracking and referral attribution. They improve the experience and credit referrals correctly.
- Analytics: first-party product usage events, used in aggregate to improve the product. We do not run advertising or marketing cookies.
Controlling storage
You can clear cookies and site data for this domain in your browser settings at any time. Doing so signs you out and clears any unsaved local draft. Blocking storage entirely will prevent sign-in and checkout from working.
Third-party cookies from Stripe, Google and YouTube are governed by their own policies. What we do with the data we receive from them is described in the Privacy Policy.
