Tiny Studio Tycoon privacy

Last updated November 7, 2026

This page explains what Tiny Studio Tycoon saves and where. It adds to my main privacy policy.

Two ways to play

You can play on this website or as an app inside KozaChat. The two versions handle your data differently.

On this website

No account, and it never asks for your name, email or anything personal.

Your progress and settings (like dark mode and the size setting) are saved in your browser on your own device. They never get sent to me or anyone else. You can delete them any time by starting a new studio in the settings tab or clearing your browser's data for yzscripts.dev. The game previews on my site run in a demo mode that doesn't save anything.

On KozaChat

The KozaChat version saves your studio to your KozaChat account so you can keep playing on any device. That means some information leaves your device and is stored on a server I run. Here's all of it.

How it knows who you are. When you open the app, KozaChat gives the game a short-lived pass that expires after about 10 minutes. My save server asks KozaChat which account that pass belongs to. KozaChat's answer can include your user ID and username, but my server only uses your user ID and doesn't save anything else from it. To avoid asking KozaChat every few seconds, the server remembers which pass goes with which user ID for up to about 8 minutes. That's only kept in memory, never in the database.

What's stored. One record per player:

Your username, display name, avatar, email, messages and servers are not stored.

Where. The save server runs on Cloudflare Workers, and the records are in a Cloudflare D1 database in my Cloudflare account.

IP addresses. Saving doesn't use your IP address, and it's never put in the database. I also have request logging turned off for the save server, so there's no record of who connected, from where or when. Every connection on the internet carries an IP address (it's how the reply finds its way back to you, like a return address on an envelope). Cloudflare reads it in the moment to deliver each save and handles it under its own privacy policy. I never see it or keep it. Cloudflare does show me basic totals for the save server, like how many requests it got, without any IP addresses or details about who made them.

Who can see it. Only me, plus Cloudflare as the host. Other players can't see your save, and I don't share it, sell it or use it for ads or analytics.

What the app doesn't do. It doesn't read messages, post in your server or ask for any server permissions.

How long it's kept. Your record stays until it's deleted, even if you stop playing for a long time. Closing the game, logging out of KozaChat or a KozaChat update doesn't remove it. Starting a new studio in the settings tab erases your game save, but your user ID, light or dark mode choice and last save time stay in the record. If you want the whole record deleted, contact me and I'll remove it. If I ever stop offering the KozaChat version, I'll delete all saved records.

Save codes

Both versions let you copy a save code. It's your whole save, studio name included, packed into text. It's only made when you ask for it and isn't sent anywhere. Anyone you give it to can load your studio, so only share it with people you trust.

Changes

If the game starts saving anything new, or saves it somewhere new, I'll update this page first.
