Cookie Policy

This policy explains what JN Tempo stores on, or reads from, your device when you use the website at jntempo.jnhorizon.com and the JN Tempo app. It is provided by JN Horizon Ltd. Our Privacy Notice explains how we use personal data more generally.

1. In short

• JN Tempo does not use analytics, advertising or tracking cookies.
• It stores a small amount of information in your browser's local storage: your sign-in session, and some display preferences.
• The sign-in session is strictly necessary for the service you ask for, so it does not need consent.
• Display preferences are stored only to remember choices you make. You can switch this off at any time using the setting at the end of this page.

2. What we store

Strictly necessary

Sign-in session (sb-…-auth-token and related entries, local storage)

• Keeps you signed in, and lets the app prove to our servers who you are, while you use JN Tempo.
• Set when you sign in or verify your email. Removed when you sign out. If you do not sign out, it stays until it expires or you clear your browser storage.
• Provided by our authentication provider, Supabase, on our behalf.

Your choice to switch off display preferences (jn-tempo-preferences-off, local storage)

• Stored only if you switch display preferences off, so that JN Tempo keeps respecting that choice.
• Removed if you switch them back on.

Display preferences

These remember choices you make about how JN Tempo looks and works on this device. They are set only when you make a choice, and they are not used for any other purpose.

• jn-times-theme: your light, dark or system colour choice. Read before the page appears, to avoid a flash of the wrong colours.
• jn-tempo-sidebar-collapsed: whether you collapsed the app's side menu.
• jn-tempo-analytics-order: the order you arranged the cards on the analytics page.
• jn-tempo-rename-notice-dismissed: that you closed the notice about the change of name from JN Times.
• jn-tempo-tour:…: your progress through the guided tour, if it cannot be saved to your account.

They stay until you clear them, switch them off below, or clear your browser storage.

3. Other providers

Cloudflare. Our website is delivered through Cloudflare's network, which protects it against attacks. Cloudflare may set a strictly necessary security cookie (such as __cf_bm) if it needs to tell people apart from automated traffic. We did not see Cloudflare set cookies during normal use when we last checked, on 19 October 2026.

Stripe. When an Admin pays for a subscription or manages billing, they are sent to pages hosted by Stripe. Stripe sets its own cookies there, for example to process payments securely and prevent fraud. Stripe's cookie policy applies to those pages. JN Tempo's own pages do not load Stripe's scripts.

4. Your choices

• Display preferences. Use the setting at the end of this page to switch them off. When you do, JN Tempo deletes the preferences already stored in this browser and stops saving new ones. The app still works, but it will not remember those choices. The setting applies to this browser on this device.
• Sign-in session. Sign out to remove it. Blocking it stops you signing in.
• Your browser. You can clear or block local storage and cookies in your browser settings. Your browser's help pages explain how.

5. Changes to this policy

If we start using a new kind of storage, we will update this policy before we do, and ask for your consent first where the law requires it. Earlier versions stay available in the archive of earlier versions.
