Privacy Policy
Last updated: 5 June 2026
1. Who we are
Proximath is a daily word game operated from the United Kingdom. If you have any questions about this policy, please contact us at proximath@gmail.com.
2. Data we collect
When you create an account and play the game, we collect:
- Email address — provided when you register or sign in with Google
- Game results — whether you solved the daily word and how many guesses it took
- Guess history — the words you entered in each game
- Score statistics — your win rate, current streak, and day ranking
You can play without an account; in that case your game state is stored only in your browser's local storage and is not sent to our servers.
3. Why we collect it
- To provide and maintain your user account
- To track your scores, streaks, and rankings across devices
- To prevent duplicate submissions for the same daily puzzle
- To improve the game based on aggregated, anonymised usage patterns
4. How we store it
All account and game data is stored in Supabase, a managed cloud database service. Every table is protected by Row Level Security (RLS) policies, meaning each user can only access their own data. Data is encrypted in transit (TLS) and at rest.
5. Third-party services
We use the following third-party services to operate the game:

6. Cookies
We use two categories of cookies:

- Advertising cookies — set by Google AdSense to serve relevant ads and measure their performance. You can opt out via Google Ad Settings.
7. We do not sell your data
We do not sell, rent, or trade your personal information to any third parties for their marketing purposes.
8. Your rights
Under UK data protection law (UK GDPR) you have the right to access, correct, or request deletion of your personal data. To exercise any of these rights, email us at proximath@gmail.com and we will respond within 30 days.
