PUZIGO is a jigsaw puzzle game published on Steam by Nexelune. This page describes exactly what data the game sends, why it is sent, and what is kept.
The short version
- Your puzzle images never leave your PC. Images you add through the Image Import Unlock DLC are read and processed locally.
- The only data sent to us is what is needed to award your Steam achievements and to keep those achievements honest.
- We do not ask for, and do not receive, your name, email address, or payment details.
- We do not use advertising or analytics services in the Steam version, and we do not share data with third parties for their own purposes.
What the game sends
PUZIGO contacts api.puzigo.com when you begin a puzzle and when you complete one. Each request contains:
| Steam authentication ticket | A short-lived token issued by Steam. We pass it to Valve, and Valve tells us which Steam account it belongs to. We never accept an account ID supplied by the game client itself. |
|---|---|
| Piece count | How many pieces the puzzle had. |
| Time taken | How long the puzzle took, in seconds. |
| Completion time | When you finished the puzzle. It is used only to check the result against the time you started, and is not stored. |
| Assist flag | Whether you completed the puzzle without using assist features. Some achievements depend on this. |
| Event ID | A random identifier for that one completion, so the same result is not counted twice. |
| Game version | Which build you are running. |
Nothing about the image you were assembling is sent — not the file, not its name, not its dimensions.
If a save cannot be read
Very rarely a save file becomes unreadable. When that happens PUZIGO can send us a short diagnostic report so we can find the cause and stop it happening again. Nothing is sent unless you agree. The game shows you the exact contents first, and sending is off by default.
The report describes only the shape of the failure. In full, it can contain:
- an error code and which stage of loading failed;
- how far the piece file was from the size it claimed — the difference only, not the sizes themselves;
- whether the piece file was still there at all;
- the piece count you chose, rounded to one significant figure (so 1,036 pieces is reported as 1,000);
- the size of the save file, rounded down to the nearest kilobyte;
- the version numbers involved and your operating system;
- how long ago the save was last written;
- whether Steam Cloud is switched on;
- whether the puzzle used a built-in picture or one you added, because the two are handled by different code.
The report contains no file names and no text you typed. The name of your image, the names you gave to sorting cells, and the contents of your save are not included. The piece count and the file size are rounded precisely so that they cannot be worked backwards into the shape of your picture or the amount you typed. Your Steam ID is attached, in the same way and for the same reason as above.
Why it is sent
Steam achievements in PUZIGO are granted by our server rather than by the game on your PC. This keeps achievements meaningful: a modified game client cannot hand itself achievements it did not earn. Granting an achievement requires knowing which account earned it, which is what the Steam ticket establishes.
What is stored, and for how long
| Completion records | Steam ID, event ID, piece count, assist flag, time taken, game version, and the time we received it. Kept while the game is operated, so achievements can be re-granted if a Steam write fails. |
|---|---|
| Progress summary | Your highest completed piece count, and which no-assist milestones you have reached. |
| Session start times | Deleted as soon as the matching completion is accepted. |
| Anti-cheat log | Records of completions that failed validation. Automatically deleted after one year. |
| Save failure reports | Only if you agree to send one. Steam ID and the fields listed under “If a save cannot be read” above. Kept while the game is operated, so that patterns across builds remain visible. |
We do not store IP addresses. Our hosting provider, Cloudflare, processes network-level information such as IP addresses to deliver requests and to block abuse; that is handled under Cloudflare's own terms and is not retained by us.
Save data
Your saves, settings, and completion history are stored on your own PC. If you have Steam Cloud enabled, Valve synchronises those files between your devices. We do not receive them.
Playing offline
PUZIGO is fully playable without an internet connection. Completions are queued on your PC and sent the next time you play online, so achievements are not lost.
Your choices
If you would like your records removed, contact us with your Steam profile and we will delete them. Note that achievements already granted are held by Steam, and can be cleared from your Steam profile.
