Privacy policy
Last updated: October 13, 2026
The short version
- You don't need an account. We never ask for your email, phone number, real name or location.
- Your game is saved on your own device. If you use cloud save, a copy is stored under a secret code only you have.
- Other players in your city see the name you pick, your character and a few game details.
- No ads, no tracking cookies and no analytics. We don't sell your information.
Who we are
JapaGrind is made by Zapex Technology Inc., Calgary, Alberta, Canada ("we", "us"). We are responsible for the information described here. Questions or requests: support@zapextech.ca.
What we collect and why
| Information | Where it lives | Why |
|---|---|---|
| Your game progress, settings, achievements and outfit | Your device (browser storage) | So the game remembers where you left off |
| A random player ID (not linked to who you are) | Your device, and with leaderboard scores and reports | To tell players apart, stop spam and handle reports |
| Player name, colours and outfit; your position, game day, job and home in the game | Sent live to other players in the same city; not stored by us | So you can see and meet other players |
| House invites and streamer votes: your player name or a random viewer ID, and the choice you made | Sent live to the other player or the streamer; not stored by us | To share a house in the game, or to let viewers vote in "chat decides" mode |
| Leaderboard results: player name, city, game stats, and a private city code if you use one | Our database | To show the leaderboards |
| Cloud save: a copy of your game and profile, stored under your secret save code | Our database | So you can continue on another device |
| Player reports: the reported player's name and ID, your player ID and the reason | Our database (only we can read it) | To keep the game safe |
| Technical data such as IP address and browser type | Our hosting and database providers' server logs | To run, secure and fix the service |
Chat in JapaGrind uses preset phrases only. Players cannot type free messages to each other, so we do not collect chat messages.
Who helps us run the game
- Vercel hosts the website and game.
- Supabase runs our database and live multiplayer connection.
- Cloudflare manages our domain name.
These providers process data on our behalf and may store it outside Canada, including in the United States. Fonts and images are served from our own site, not from third parties.
How long we keep it
- Leaderboard results stay up while the leaderboards exist.
- Cloud saves are kept until you ask us to delete them, or after 24 months without use.
- Player reports are kept for up to 12 months.
- Information on your device stays until you clear your browser's site data.
Your choices and rights
- Play without the internet features: your game still saves on your device.
- Use any nickname. Please don't use your real full name.
- Ask us to see, correct or delete your leaderboard results or cloud save. Email us with your player name and, for a cloud save, your save code (in the game menu under "Play on another device").
- Under Canadian privacy law (PIPEDA and Alberta's PIPA), you can also complain to the Office of the Privacy Commissioner of Canada if you are unhappy with how we handle your request.
Children
JapaGrind is meant for players aged 13 and over. We don't knowingly collect personal information from children under 13. If you believe a child under 13 has shared personal information, for example a real name as a player name, email us and we will remove it.
Security
Data is sent over encrypted connections (HTTPS). Our database only accepts changes through checked functions. Player reports can only be read by us. No system is perfectly secure, so please keep your save code private.
Changes
If we change this policy, for example if we add ads or purchases, we will update the date above and explain the change on this page before it takes effect.
