Cookie Policy
Last updated: 3 May 2026
This Cookie Policy explains how Lettr Australia Pty Ltd ("Lettr") uses cookies and similar browser-storage technologies on lettr.com.au. It should be read alongside our Privacy Policy.
1. What cookies are
Cookies are small text files that a website asks your browser to store. Each time you return, your browser sends those files back, which is how the site remembers things like whether you're logged in or what theme you've chosen. Similar technologies — local storage, session storage, and pixel beacons — work in much the same way and are covered by this policy.
Cookies set directly by lettr.com.au are "first-party" cookies. Cookies set by services we use (Stripe, Supabase, PostHog, Sentry) are "third-party" cookies — see §3.
2. The categories we use
We use four categories of cookies. Only Essential cookies are strictly required for the Platform to function; the others can be disabled in your browser without losing core functionality.
| Category | Purpose | Duration | Optional? |
|---|---|---|---|
| Essential | Authentication, session security, CSRF protection, and core platform functionality. Without these, you can't log in or stay logged in. | Session — 30 days | No |
| Preferences | Remember your settings — theme (light/dark), language, recent search filters. | Up to 1 year | Yes |
| Analytics | Aggregate usage measurement so we can understand which features help, which pages confuse, and where the platform breaks. No ad targeting. | Up to 1 year | Yes |
| Diagnostics | Anonymised error context attached to crash reports so we can fix bugs. | Session | Yes |
We do not use cookies for cross-site advertising, behavioural ad targeting, or selling data to third parties.
3. Specific third-party cookies
The third parties listed below set cookies on your device when you use the Platform. Each links to its own privacy notice.
| Provider | Used for | Notice |
|---|---|---|
| Supabase | Auth tokens, session refresh | supabase.com/privacy |
| Stripe | Fraud prevention on payment pages, Connect onboarding | stripe.com/au/privacy |
| PostHog | Aggregate product analytics | posthog.com/privacy |
| Sentry | Error monitoring and crash reports | sentry.io/privacy |
| Vercel | Performance metrics and edge routing | vercel.com/legal/privacy-policy |
4. Managing your cookies
Most browsers let you block, delete, or limit cookies through their settings. The specific menu varies — search your browser's help for "cookie settings":
- Chrome: Settings → Privacy and security → Third-party cookies
- Safari: Settings → Privacy → Manage Website Data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Edge: Settings → Cookies and site permissions
Disabling Essential cookies will break authentication and most features. Disabling Preferences, Analytics, or Diagnostics cookies is fine — the Platform will keep working, you'll just lose some personalisation and we'll have less data to improve it.
You can also instruct your browser to send a Global Privacy Control (GPC) signal. We honour GPC signals as a do-not-track preference for analytics and diagnostics cookies.
5. Changes to this policy
We may update this Cookie Policy as our cookie use evolves. We will post the updated policy on this page and refresh the "Last updated" date. For material changes — for example, adding a new analytics provider — we will notify you by email and on the Platform.

We tell you what we collect, why, and how to turn it off — without burying it in fine print.
