Cookie Policy

Last updated: May 2026

This page lists every cookie and browser-storage key Prepliq sets, what it is for, and how long it stays on your device. It complements our Privacy Policy.

1. What are cookies and similar technologies?

A cookie is a small text file a website asks your browser to store. We also use the related browser feature localStorage, which keeps values on your device but does not automatically send them to a server. Both are covered by this policy.

2. Strictly necessary cookies

These are required for Prepliq to work and are exempt from consent under § 25 (2) TTDSG.

NamePurposeDuration
better-auth.session_tokenKeeps you signed in (HttpOnly, Secure, SameSite=Lax).7 days
prepliq_authedLightweight signal that you are signed in, so the landing page can show “Dashboard” instead of “Sign in” without a server round-trip. Holds only the value 1 — no personal data.7 days

3. localStorage values

These keys live in your browser’s localStorage. They never leave your device and are never transmitted to our servers.

KeyPurposeDuration
cookie-consentRecords that you have seen and accepted or declined the cookie banner.Until cleared
plan-expiry-banner-last-dismissedDate stamp so the “your plan is expiring” banner is not shown more than once per day.Until cleared
conversation-guide-dismissedRemembers that you closed the conversation-mode help card so it does not reappear.Until cleared
fillInBlanks_hintSeenRemembers that you saw the gap-fill exercise hint.Until cleared
coach-mark-*Per-feature flags so first-time tooltips and coach marks do not reappear after you have seen them.Until cleared

4. Third-party cookies

Prepliq does not embed third-party tracking scripts on the main site. When you reach a checkout page, you are redirected to Stripe’s hosted Checkout at checkout.stripe.com. Stripe sets its own cookies there for fraud prevention and session continuity, governed by Stripe’s privacy policy.

We do not currently use analytics, advertising, or social-media tracking cookies. If that changes, we will update this page and ask for your consent before any non-essential script loads.

5. Managing or deleting these values

  • You can clear cookies and localStorage at any time from your browser settings (typically: Settings → Privacy → Clear browsing data).
  • Disabling the better-auth.session_token cookie will sign you out and prevent you from staying signed in.
  • Clearing localStorage will reset coach marks and hint dismissals but will not affect your account or saved exam attempts — those live in our database.

6. Changes to this policy

If we add or remove any cookies or localStorage keys, this page will be updated and the “Last updated” date at the top revised.
