Privacy

Jigsaw Grove does not know who you are, unless you choose to tell us by writing to us or leaving an email address for a reply. There is no account to make, and nothing here is trying to work out who is sitting at the other end. This page says what that means in practice, in plain words.

It describes the site as it is today, and the site is young. As it grows we expect to add things that touch this page: ads to pay for it, and optional accounts for things like keeping your puzzles across devices. The sections on accounts and ads say what is planned for each. Whatever arrives, it will be described here, in the same plain words, before it appears on the site.

No accounts

Today you do not sign in, so there is no name and no password held anywhere, and no email address unless you give us one yourself (see "When you write to us" below). There are no advertising tags and no social media buttons, and nothing here follows you to other sites.

Accounts are planned as an optional extra, for people who want their puzzles to follow them between devices. When they arrive, playing without one will work the way it does now, and this section will say exactly what an account stores.

What is kept on this computer

A puzzle you have started, the pictures you have finished, your run of Daily Jigsaw days, and your settings are all saved by your own browser on your own machine. These saves are not sent to us and do not reach a server. That is also why a puzzle you started on one computer is not waiting for you on another, and why clearing your browsing data clears it.

Your browser also makes up a random code for itself and keeps it. It is sent with a star rating, a finish time or a message (see below), so that one browser counts once. It says nothing about who you are, and clearing your browsing data throws it away.

If a star rating cannot reach us, for example because the connection dropped, your browser keeps it and tries again the next time you open a puzzle. It keeps only the picture, the number of stars, and when and how many times it has tried, and gives up after five tries or thirty days.

A picture of your own is kept the same way. When you play one on the Your Pictures page, your browser reads the file and keeps the picture on your machine. It is never uploaded: we never receive it, we cannot see it, and it appears in no link that could be shared. Your browser holds up to twelve of them, you can remove any one of them on that page, and clearing your browsing data removes them all. A puzzle made from your own picture sends us no rating and no finish time.

Two small files called cookies can be there as well. One holds the random id used for counting visits; it lasts thirteen months from your last visit, and your browser keeps a copy of the same id beside it. The other is set only for the few people who build the site, so that their own visits stay out of the counts; it does nothing else, and you will not have it.

You can remove all of it at any time by clearing this site's data in your browser settings. We cannot remove it for you, because we cannot see it. What we do keep on our side is described in the next two sections.

Stars and finish times

When you finish one of our puzzles, your time is sent to us: which picture, how many pieces and which piece shape, and how many seconds it took. When you give a picture stars, we are sent the picture and the number of stars. If you change your mind and give it different stars, the new ones replace the old.

Beside each one we keep the date and time, the random code your browser made for itself, and a scrambled form of your internet address, made with a secret key, so that the address itself is never stored. They are there so that one household cannot give a picture a hundred ratings, or fill the list of times. For the same reason, we count how many of these each scrambled address has sent in the last ten minutes. Our own stars and times, from the people who build the site, are marked so that they stay out of the totals.

What other players see is only the totals. On a puzzle's page that is the average number of stars and how many people gave them, and, for each number of pieces and piece shape, the best time, the average time and how many people finished. Nothing on the page says who.

When you write to us

A message you send on the feedback page is kept in the same database: what you wrote, the face you chose if you chose one, your email address if you left one, the page you were on before you came to the form, the language of the page, the date and time, and the same random code and scrambled address as above. Your email address is used only to write back to you. Messages are read only by the person who runs the site.

Email you send to [email protected], including a problem report sent from a puzzle page, arrives in the Gmail inbox the site uses for its post, and is kept there like any other email.

Counting visits

We count visits and puzzles played so that we can see what people enjoy and make the site better. That is the whole reason. The counting is done for us by a tool called PostHog, running on servers in the European Union; they handle the counts on our behalf and do nothing else with them. It works under a random id in a cookie the site sets itself, so a player who comes back is counted once rather than twice. It does not know your name, and it does not follow you to other sites.

We count only what we have chosen to count; nothing is recorded just because you clicked. What is sent is the page you are on, the page that brought you here, the language you are reading in, the choices you make on a page, such as how many pieces a puzzle should have, and what happens in a puzzle: which picture, how many pieces, how long it took, and the stars you gave it. As with any website, your browser also says which browser and system you use and how big your screen is, and PostHog works out roughly where in the world you are from your internet address. If something on a page goes wrong, a description of the error is sent too, so that we can fix it. When you search the pictures, the length of what you typed and the number of pictures found are sent, and if nothing is found, the words too, with nothing that says who typed them. When you write a problem report on a puzzle page, only its length is sent. The words of a search are taken out of every address before anything leaves your browser.

We do not record your screen. Nothing here watches where the mouse goes or plays a visit back afterwards, and there are no recordings to ask us for.

The counts are kept for a year and then go. The id in the cookie lasts thirteen months, so a browser that stops visiting is forgotten. Nothing that is counted is sold, and nothing is shared with anyone else.

Turning the counting off

You can turn it off whenever you like, on the settings page. The switch takes effect at once: nothing more is counted, and the cookie and the copy of the id are removed. If your browser sends the Global Privacy Control signal, or the older Do Not Track one, we take that as your answer and count nothing, and the settings page says so. The switch is for the counting only: stars you give and finish times are still sent, as described above, because they are part of the puzzles.

The site has to be hosted somewhere

These pages, and the pictures, are served by Cloudflare, the way a large part of the web is. Your request reaches their servers in order to reach the site at all. We do not add anything to it. Cloudflare also runs, for us, the small database that holds the stars, times and messages described above.

Ads

There are no ads on Jigsaw Grove, and nothing counted here is used for advertising. Ads are how we expect the site to pay for itself one day, so they may come. Before the first one appears, this page will be updated to say plainly which ad network it is and what that network does.

Asking us anything

Write to [email protected]. A person reads it.
