What we set
| Name | What it does | How long |
|---|---|---|
| hearn.session_token | Keeps you signed in and protects your account. Shared across hearn.app and web.hearn.app so you sign in once. | 7 days, renewed while you use Hearn, or until you sign out |
| hearn.session_data | A short-lived signed copy of your session that saves a database lookup on every request. | 5 minutes |
| PARAGLIDE_LOCALE | Remembers your interface language, on hearn.app and web.hearn.app. | About 400 days |
| hearn-theme | Remembers light, dark or system appearance, so a page does not flash the wrong colour. | About 1 year |
These are strictly necessary for what you ask Hearn to do (sign in, show the page in your language), so they do not need consent where the law makes that distinction.
Storage on your device
Besides cookies, Hearn uses your browser's local storage and IndexedDB (and, in the mobile apps, a local database and secure storage). They hold guest-mode projects, copies of your synced projects so Hearn opens fast and works offline, changes waiting to sync, pictures, and interface preferences. This is how guest mode keeps your writing on your device. Clearing site data removes it; for guest projects that means they are gone, so export first.
Third parties
When you choose Sign in with Apple or Google, those companies may set their own cookies on their own pages. If you pay on the web, our payment provider's checkout may set cookies needed to process the payment and prevent fraud. Our hosting provider, Cloudflare, may use technical signals and cookies to protect the service against abuse. We do not load advertising networks, social-media trackers or third-party analytics on hearn.app or web.hearn.app.
If we ever add non-essential cookies, such as analytics, we will update this page and ask for your consent first where the law requires it.
Your controls
You can clear or block cookies and site storage in your browser settings. Blocking the essential ones will stop you from signing in or keeping your language. You can change language and theme at any time from the controls in the app and on this site.
