This page explains what podesentar collects when you open it, why, how long it's kept and who can see it. Questions: [email protected].

what we collect

• Connection details — your IP address, browser and device type (user agent) and screen size.
• A device ID — a random ID created the first time you visit, stored in your browser (localStorage) and in a cookie called cid that lasts a year. It lets the organiser's dashboard recognise your device across reloads, and lets the server show a blocked device the "blocked" page. The first four characters are shown in the bottom-left corner of the page. A short-lived sessionStorage entry is also used, only when a device has been blocked.
• A device number (1, 2, 3…) given to your device ID, so the organiser can tell devices apart in a room.
• Sync status, about twice a second while the page is open — whether it's waiting or playing, network round-trip time, how far playback is from where it should be, playback speed, and whether sound is on.
• Playback telemetry during a video — position, timing drift, playback speed, round-trip time and corrections, with timestamps.
• Error reports if something goes wrong — the error message and where in the page it happened, plus a short technical snapshot (whether the video was loading, whether you were online, your connection type such as "4g", whether the tab was in the background, and any browser features that are missing). You're shown a reference code for each report.
• The network name of your IP address (reverse DNS), if it has one.

We don't use analytics, advertising or tracking services, and we never ask for your name, email or location.

why we collect it

• To keep every device in sync — different browsers need different handling (for example Safari).
• To show the organiser which devices are connected and whether they're in sync.
• To find and fix problems.
• To protect the service: rate limits, blocking devices or IP addresses that abuse it, and investigating attacks.

how long it's kept

• Connected devices list (IP, device, screen, status) — in memory; removed about 30 seconds after your device stops checking in.
• Playback telemetry — in memory, up to 20 playbacks per device; deleted about 2 hours after its last update, or when the server restarts. The organiser may save a copy while investigating a problem.
• Server log files (requests with IP address and browser, devices joining and leaving, error reports) — kept for up to about 30 days, then deleted automatically. The system log keeps short technical lines without IP addresses or browser details; entries from before 25 october 2026 may still include them until the system removes them.
• Device numbers — saved with the device ID; the oldest are removed once more than 5,000 devices have joined.
• Blocks — a blocked device ID or IP address, and the reason, are kept until the block is lifted.
• On your device — the device ID stays in your browser until you clear this site's data; the cookie expires after a year.

who can see it

Only the organiser, through a password-protected dashboard on our own server. We don't sell, rent or share your data with advertisers or other third parties. We may disclose information if the law requires it.

All traffic to this site passes through Cloudflare (a proxy and secure tunnel), which processes IP addresses and request details to deliver it, possibly in other countries. See Cloudflare's privacy policy.

your choices

• Clear this site's data in your browser to remove the device ID and cookie; you'll get a new ID next time.
• To see, correct or delete what we hold about your device, email [email protected] with the four-character code from the bottom-left corner of the page (or an error reference code). Information needed to keep a block in place may be kept while the block lasts.
