What this service is
KinoDuo is a tool for several people to watch video at the same time. The service keeps pause, seeking and playback speed in sync, and adds chat plus voice and video calls between people in a room.
What data we process
- Room code — a random string from the page address. It is kept in the server’s memory and deleted 30 minutes after the last person leaves the room.
- Participant name — you give it voluntarily. It is stored in your browser and passed to the other people in your room so they can see who is writing.
- Chat messages — the last 50 messages in a room are kept in the server’s memory so that someone joining later sees the context. In addition, the message text, your login, the room code and the time are saved in the database: this is needed to look into complaints about behaviour in a room. That archive is not shown to other participants — a room still displays only its recent messages, and only while it is alive.
- Technical records — your IP address, browser type and request time go into the server logs. They are needed to diagnose failures and to guard against abuse.
What we never receive
- Video. It does not pass through our server. A file never leaves your device, links are opened by your browser directly, and embedded players run on the side of the service they belong to.
- Calls and screen sharing. Audio, camera video and the screen image travel directly between participants. The server only helps establish the connection and never sees the content.
- Your password in the clear. It is turned into an irreversible fingerprint (scrypt) before anything is written to disk. The original password cannot be recovered from it, and we do not know it.
Your account
You can watch video without an account. An account is only needed for chat, calls, screen sharing and stickers. If you sign up, we store your login, email address, the name shown in the room, the password fingerprint, and the dates you registered and last signed in. The email is only a second way to sign in — we send no mail and pass the address to nobody.
Your session rests on a signed cookie that lasts 30 days. It is marked HttpOnly
and Secure: third-party scripts cannot read it, and the browser will not send it over an unencrypted connection.
Cookies and browser storage
The service itself keeps settings in your browser: the chosen theme, your name, the frame zoom and your answer to the consent prompt. None of it leaves your device. The only cookie the service sets is the one holding your session; without an account there is none at all.
If you agreed to cookies, Google AdSense ads are shown on the pages. Google and its partners may use cookies to show ads based on your interests. Declining personalisation does not switch ads off — they simply become non-personalised. You can adjust this in Google ad settings, and you can change your choice on our site by clearing the site data in your browser.
Sharing with third parties
We do not sell or pass your data to third parties. The exception is the Google ad network, which processes data according to its own policy, and requirements of the law.
Retention
Chat messages are saved in the database and kept indefinitely. The history never appears in the room itself: only the last 50 messages are shown there, and only while the room is alive. The video link and any attached sticker packs are written to disk so a room survives a restart — and are deleted with it 30 minutes after the last person leaves. Account data is kept after the account is closed: the record is marked as closed and stops being used, but it stays in the database. The login and the email address are freed up, so they can be registered again. If you need your data physically erased, write to us and we will erase it on request. Request logs are kept for no longer than 30 days.
Your rights
Room data disappears once the room closes — leaving is enough to delete it. Settings are removed by clearing the site data in your browser. If you have an account and want it deleted along with everything in it, write to us from the address you registered with and we will delete it.
