Cookie Policy
Last updated: 19 October 2026
Short version: You can play without third-party cookies or trackers. We do not use Google Analytics, advertising cookies, or third-party tracking software. We use a small number of strictly necessary first-party items to keep you signed in and save your game progress. Because we use zero non-essential cookies and zero third-party trackers, no cookie consent banner is needed or displayed.
What are cookies?
Cookies are small files a site stores on your device. “Similar storage” (such as localStorage) works the same way. We group everything we use into the categories below.
Strictly necessary
These are required for the site to work and do not need consent. They are never used for cross-site tracking.
| Item | Purpose | Lifetime |
|---|---|---|
pm_session (httpOnly) | Keeps you signed in or holds an anonymous session for progress saving. | 90 days |
pm_sh | Signals that a session exists (carries no secret). | 90 days |
| Code-verification cookie (httpOnly) | Confirms your one-time sign-in code. | 15 minutes |
pm_user (localStorage) | Holds your account id, or the anonymous id we mint for you. It keeps your progress attached to you. | Until cleared |
pm_rounds_v1_<game> (localStorage) | Saves the last 200 rounds of each game on your device: the “Your Stats” panel reads them. | Until cleared |
pm_fav_games, pm.favs.v1 (localStorage) | Remembers the games you marked as a favourite. | Until cleared |
| Per-game settings (localStorage) | Saves your difficulty, sound, and mode choices on your device. | Until cleared |
First-party technical telemetry
Operates under legitimate interest (GDPR Art. 6(1)(f)). These non-identifying telemetry events are processed directly on PlayMemorize servers to monitor system health and resolve bugs. They are never shared with third parties, never used for advertising, and never used for cross-site tracking.
| Item | Provider | Purpose |
|---|---|---|
| First-party telemetry events | PlayMemorize | Measures page views, reading scroll depth, and interaction clicks without identifying individuals. |
pm_engagement_lang_v1 (localStorage) | PlayMemorize | Records which languages you played in, for the polyglot badges. |
pm_events_pending_v1, pm_events_pending_v2 (localStorage) | PlayMemorize | Holds offline first-party analytics events until your browser reconnects. |
Game round records
When you are signed in, we record the outcome of each game round on our own servers: which game, whether you were correct, the score, the duration, and the difficulty. We use this for your stats, your badges, and the leaderboard, and it is part of the service you asked for. It does not go to third parties and it is never used for cross-site tracking. If you are not signed in, these records stay on your device.
Zero third-party cookies or trackers
PlayMemorize does not use Google Analytics, advertising cookies, or third-party tracking scripts. No third-party network has access to your activity on PlayMemorize.
How to control cookies
Since PlayMemorize uses only strictly necessary first-party storage, no consent banner is required by law. You can manage or clear storage directly in your browser:
- Browser settings: you can view, block, or delete cookies and local storage through your browser settings at any time. Clearing session cookies will sign you out.
