Privacy notice
Pictures stay local
Puzzle generation, private picture decoding and progress storage happen in your browser. Private image bytes, filenames and puzzle positions are not sent to Jigsaw Harbor. A private picture may be stored locally on this device only to support resume.
Links and access logs
A built-in puzzle link contains only the catalog asset id and difficulty. After server reporting is activated, minimized access records may include the time, a request identifier, an allowlisted page category, method and status, a coarse browser or bot label, and the referring domain. Trusted client addresses are converted immediately into site- and UTC-day-specific one-way codes; raw IP addresses, full URLs or queries, request bodies, raw browser strings and full referrer URLs are not kept. During normal scheduled operation, detailed minimized records rotate daily and are removed within 14 days; a missed cleanup may retain them longer until the schedule is restored. Daily aggregate reports may be kept longer for comparisons, but contain no per-request codes; same-day visitor estimates are approximate and are not verified people or cross-day identifiers. Browser event analytics, advertising and tracking scripts remain disabled.
Your controls
While solving, use Clear progress in the top toolbar to remove that puzzle’s saved state. The control below shows how many puzzle progress records and whether a private picture are stored in this browser, and can clear all local data. The site does not create an account or cross-device play history.
