Yearfold is operated by Hyper Mind Technologies, LLC. This Cookie Policy explains which cookies and similar storage technologies we set on yearfold.com, why, and how to control them. Read it alongside our Privacy Policy.
What cookies are
A cookie is a small text file a website saves on your device so it can remember you between page loads — for example, to keep you signed in. Some cookies are essential to a site working at all; others are optional. We also use a few similar technologies (localStorage, sessionStorage) which behave like cookies but are stored differently by your browser.
The categories we use
We organise cookies into four categories so you can give granular consent. Necessary cookies are always on; the other three default off until you opt in.
| Category | What it does | Default |
|---|---|---|
| Necessary | Keeps you signed in, protects against CSRF, remembers your cookie preferences. Required for the site to work. | Always on |
| Analytics | Cookie-based session-replay context for our error tracker (Sentry). Note: our page-view analytics (Vercel Web Analytics + Speed Insights) are cookieless and run regardless of this setting. | Off until accepted |
| Advertising | Google AdSense — serves ads on blog and content pages and supports keeping the calculator free. | Off until accepted |
| Third-party features | Optional widgets like the Buy Me a Coffee button on the About page. | Off until accepted |
The specific cookies set on yearfold.com
| Name | Domain | Purpose | Category | Duration |
|---|---|---|---|---|
sb-access-token | yearfold.com | Supabase Auth session | Necessary | 1 hour |
sb-refresh-token | yearfold.com | Supabase Auth refresh | Necessary | 30 days |

IDE | doubleclick.net | Google AdSense ad targeting and frequency capping | Advertising | 13 months |

bmcsid | buymeacoffee.com | Buy Me a Coffee session | Third-party features | Session |
We do not use Google Analytics. We do not set any advertising-personalisation cookies unless you opt in. We do not share these cookies with anyone outside the named providers.
How to manage your preferences
The fastest path is the dedicated settings page:
- Cookie Settings — turn any optional category on or off, instantly. Your choice persists for 365 days across visits, then we ask again.
You can also re-open the banner by clearing the yearfold-consent
cookie in your browser's dev-tools panel; the banner re-appears on the
next page load.
How to manage cookies in your browser
Every modern browser lets you block or delete cookies. The relevant settings pages:
Blocking all cookies will break sign-in and saved-plan functionality — those are Necessary cookies. Blocking only third-party cookies leaves the site functional but disables AdSense and Buy Me a Coffee.
Changes to this policy
If we add a new cookie category or materially change what an existing category covers, we bump an internal version stamp which invalidates your stored consent and shows the banner again so you can re-confirm. The "Last reviewed" date at the top of this page reflects the most recent material change.
