Privacy policy

This policy covers Yume (yume.tukka.dev), made by Tukka (“we”). It was updated on 12 October 2026.

The short version

1. No accounts, no ads, and no tracking across other apps or sites.
2. Everything she does happens in your browser. Taps and cursor movements are never sent anywhere.
3. When you talk to her, what you say goes straight from your browser to the AI service you chose (OpenAI by default), with your own key. It never passes through us.
4. The site counts visits with a random ID that isn’t tied to you. That’s all we collect, and it’s deleted after 40 days.

What stays in your browser

Your browser’s local storage keeps the girl you picked, your API settings (the service’s address, your API key and the models), whether her voice is on, and your chat with each girl, so it’s all there when you come back. It stays on this device. “Remove settings” and “Forget chat” in Settings delete them, and so does clearing the site’s data in your browser. Her 3D model downloads from this site; nothing you do with her is sent back.

When you talk to her

Talking uses an AI service you set up in Settings: OpenAI, unless you enter the address of another service that works like it. Your browser sends it, with your API key:

1. what you type, and the recent chat, so she can reply;
2. when you talk out loud, a recording of what you say, so it can be turned into text (the microphone only listens during a call you start, and never while she’s speaking);
3. her replies, so they can be spoken in her voice.

These go from your browser straight to that service; we never see them, your key or your recordings. The service handles them under its own terms and privacy policy, such as OpenAI’s, and bills your account for them. Her voice is AI-generated.

What we collect

Each time a page opens, the site sends a short message to our server. It contains:

1. a random ID, made in your browser on your first visit and kept in its local storage;
2. that the visit is to Yume, on the web;
3. the address of the page (such as /privacy) and, for the first page you open, the address of the site that sent you there.

Our server adds the time and the country you’re in, which Cloudflare works out from your IP address. It also notes your browser, operating system and type of device (phone, tablet or computer), read from the user agent your browser sends. Of the referring address, it keeps only the website’s domain.

We don’t store your IP address or your user agent. The random ID isn’t linked to your name, email, phone number, advertising ID or any other identifier, and we don’t try to find out who you are. Messages travel encrypted, over HTTPS.

Why we collect it

To count how many people use Yume and which pages they open, so we know what’s worth improving. We don’t sell this data, share it, or use it for advertising.

How long we keep it

Each record is deleted 40 days after it’s made.

Where it’s kept

On our own server in France, in the European Union. Cloudflare delivers this site and passes the messages on to our server, so it handles your IP address along the way, under its own privacy policy.

Your choices

You can reset the random ID whenever you like by clearing the site’s data in your browser, which also forgets your girl, your settings and your chats. Your old records are then no longer connected to anything, and they’re deleted within 40 days.

Children

Yume isn’t made for children under 13, and the usage data above isn’t tied to anyone’s identity, whatever their age.

Changes

If this policy changes, we’ll update this page and the date at the top.
