Cookie Policy
Last updated: 7 June 2026
What is a cookie?
A cookie is a small text file placed on your device when you visit a website. Cookies serve different purposes — some are essential for the site to work, others track your behaviour across the web for advertising. This page explains exactly what we set and why.
What we use
We keep this as lean as possible. Here is the complete list of what is set in your browser when you use startdoin.com:
Strictly necessary
| Name | Type | Purpose | Duration | Provider |
|---|---|---|---|---|
| doin_cookie_consent | localStorage | Stores your cookie preference (accepted / declined) so we do not show the banner on every page visit. | Persistent (until you clear browser storage) | DOIN' |
| sb-*-auth-token | localStorage | Keeps you signed in between visits. Set by Supabase Auth. Without this you would need to sign in on every page load. | 30 days (refreshed on activity) | Supabase |
| __cf_bm | Cookie | Cloudflare bot management. Distinguishes legitimate visitors from automated traffic. Required for site security. | 30 minutes | Cloudflare |
| __cflb | Cookie | Cloudflare load balancing. Routes your requests to the nearest server. Required for site performance. | Session | Cloudflare |
Analytics (not yet active — consent required before activation)
| Name | Type | Purpose | Duration | Provider |
|---|---|---|---|---|
| mp_* | Cookie | Mixpanel product analytics. Helps us understand how people use the app so we can improve it. Only loaded if you accept analytics cookies. | 1 year | Mixpanel, Inc. |
We do not use advertising cookies, retargeting pixels, or any cookies that track you across other websites. We do not sell data to advertisers.
Strictly necessary cookies — no consent needed
The Cloudflare and Supabase Auth cookies above are strictly necessary to operate the site securely and keep you signed in. Under the ePrivacy Directive, these do not require your consent. You cannot opt out of these without also losing the ability to use the site.
Analytics cookies — your choice
When we activate Mixpanel analytics, it will only load if you have accepted analytics cookies via the banner. If you clicked Decline, or if you clear your browser storage, no analytics will run. You can change your preference at any time by clearing site data in your browser settings — the banner will reappear on your next visit.
Managing your preferences
- Change your choice: clear site data in your browser (Settings → Privacy → Clear browsing data → Cookies and site data for startdoin.com). The cookie banner will reappear on your next visit.
- Block all cookies: you can configure your browser to block cookies. Note that blocking the Cloudflare cookies may affect site security checks; blocking the Supabase auth storage will sign you out.
- Cloudflare cookies: managed by Cloudflare on our behalf. See Cloudflare's privacy policy.
Changes to this policy
If we add new cookies — particularly analytics or marketing cookies — we will update this page before activating them and, where consent is required, update the banner to ask for it. The “Last updated” date at the top of this page reflects the most recent change.
