Cookie Policy
Last updated 31 July 2026.
1. What we use
phdflow uses a single strictly-necessary cookie, plus browser local storage for your preferences. We do not use analytics, advertising or third-party tracking cookies. We do count page visits, but we do it on our own servers without setting anything on your device; see section 3a of the Privacy Policy for how that works.
| Name | Type | Purpose |
|---|---|---|
| phdflow_session | Essential (cookie) | Keeps you signed in (a signed session identifier). Required for the app to work. |
| phdflow-theme | Preference (local storage) | Remembers your chosen color theme. |
| phdflow-cookie-consent | Preference (local storage) | Remembers that you dismissed the cookie notice. |
2. Consent
The session cookie is strictly necessary, so it does not require consent. If we ever add optional cookies (for example analytics), we will ask for your consent first and update this policy.
3. Controlling cookies
You can clear or block cookies in your browser settings. Blocking the session cookie will prevent you from staying signed in.
