Privacy Policy
Last updated: 20 May 2026
Short version: You can play PlayMemorize without an account. We record privacy-respecting usage analytics (coarse, non-identifying technical data such as approximate country and device type) to understand how the games are used. If you choose to sign in, we additionally store your email address to identify your account and sync your progress. We never sell your data and use no cross-site advertising trackers of our own.
What we collect
PlayMemorize operates in two modes:
- Without an account (default): You don't give us your email or any account identity. We do record privacy-respecting usage analytics · see “Usage analytics” below · and your game progress is saved in your browser.
- With an account (optional): When you sign in with your email address, we store your email and a unique account identifier on our servers and sync your progress across devices. We do not store passwords · authentication uses a one-time 6-digit code sent to your email.
We do not collect payment information, precise GPS location, or social media profiles.
Usage analytics
To understand how the games are used and to keep the site reliable, we record analytics events whether or not you have an account. On your first visit we create an anonymous identifier (stored in a cookie) so we can count returning players without knowing who you are. For each visit and game round we record coarse, non-identifying technical context:
- Approximate country and region, derived from your IP address by our hosting provider. We use this to compare engagement across countries; we do not store your full IP address in our analytics tables.
- Device category (mobile / tablet / desktop), operating-system family and browser family, screen/viewport size, timezone, and language.
- Referrer and any UTM campaign tags in the link you arrived from.
- Game-round outcomes: which game, score, duration, difficulty, and streak.
The legal basis for this processing is our legitimate interest in measuring and improving the product. We also use Google Analytics 4 for aggregate statistics (see below). You can opt out of non-essential analytics via the consent banner.
Account data
If you create an account, we store:
- Your email address (used to identify your account and send authentication codes).
- Account creation date and last login date.
- A session token in an httpOnly cookie on your device, used to keep you signed in for up to 30 days.
Account data is stored on Netlify's infrastructure. You can delete your account at any time using the “Delete account” button on your /me page, or by emailing hello@playmemorize.com.
Authentication emails
When you request a sign-in code, your email address is passed to Resend (our email delivery provider) solely to deliver the code. We do not use it for marketing.
Your practice progress
Detailed game progress, streaks, and settings are saved to your browser's localStorage. This detailed data stays on your device unless you sign in, in which case it syncs to your account so it follows you across devices. (The coarse round outcomes described under “Usage analytics” are recorded separately, with or without an account.)
Data retention
Account data (email, account identifier, dates) is kept while your account exists and is removed when you request deletion. Analytics events are retained on a rolling basis · page views and performance metrics for about 90 days, error reports for up to 365 days · after which they are aggregated or deleted. You can delete your account and all associated data yourself on the /me page, or email hello@playmemorize.com if you prefer.
Cookies
If you sign in, we set two httpOnly cookies: a short-lived code-verification cookie (expires in 15 minutes) and a session cookie (expires in 30 days). These are used only to keep you signed in and are never used for advertising or cross-site tracking. Google Analytics may set its own cookies. We do not set any other cookies.
Google Analytics
We use Google Analytics 4 (GA4) to understand aggregate usage: which games are played, how often pages are visited, and which countries users come from. Google Analytics sets cookies and collects data including your IP address (anonymised), browser type, and pages visited. This data is processed by Google under their own privacy policy.
To opt out of Google Analytics tracking, install the Google Analytics Opt-out Browser Add-on.
Service workers and caching
PlayMemorize registers a service worker to enable offline use and fast loading. The service worker caches app files locally on your device. No personal data is included in this cache.
Third-party services
- Google Analytics 4 · aggregate usage statistics.
- Netlify · hosting and serverless infrastructure.
- Resend · email delivery for authentication codes.
We do not use advertising networks, social media pixels, or affiliate links.
Children
PlayMemorize is suitable for all ages. If you are under the age of digital consent in your country, please do not create an account without parental consent. Contact us to delete any account created without consent.
Changes to this policy
If this policy changes in a material way we will update the date at the top of this page. Continued use of the site after any change constitutes acceptance of the updated policy.
