Privacy
Short, because there is not much to say: the conversion happens on your machine, the site measures its audience with Google only if you let it, posts' figures are counted without keeping anything about you, and the only thing it keeps about your use is the history of your recent charts, if you have an account.

Your photo does not leave
The whole conversion (the downscale, the colour choice, the thread matching, drawing the chart) runs on your machine, in your browser. No image is sent to a server to be converted, so there is nothing to keep, nothing to analyse and nothing to lose. Cut your connection once the page has loaded and the conversion still works.
Without an account, nothing is recorded
Converting a photo, downloading a chart, browsing the gallery: none of it needs an account and nothing about you is recorded on the server. Your current settings are kept in your browser's local storage, on your device, so your work is still there when you come back — and so are the pieces already shown to you under “More ideas”, so the same ones are not offered every time. Clearing the site's data removes them.
If you sign in with Google
Signing in does one thing: it lets you publish to the gallery and comment. Google then passes us your name, your email address and the address of your profile picture. We keep those three, plus the date the account was created, your bio, the banner and featured piece you choose, and your profile photo if you upload one: your browser crops it and saves it afresh before sending it, so it arrives without its metadata, no GPS position, no camera model. Add to that your thread box if you fill it in (the threads, how many of each, the names you give your own threads), which only you can see, the pieces you like, and the members you follow: the member you follow is told in their activity, and their profile shows how many followers they have, never the list. Success cards follow from what you do on the site; for each we keep the date you earned it and its number, and your profile shows them. We ask Google for nothing else and can see nothing else: not your contacts, not your calendar, not your files.
What you publish is public
A shared chart, its title, its category, a photo of the finished piece if you add one, your comments, your hearts and your profile photo are visible to everyone, with your name on them. That is what a gallery is. You can delete your own posts and your own comments whenever you like.
The cookies, and what each one does
The session cookie keeps you signed in. It holds a random token that means nothing anywhere but this site, the page's JavaScript cannot read it, and the database keeps only a fingerprint of that token, so a copy of the database would let nobody sign in as anybody. It lasts 180 days, and expired sessions are deleted. A second, temporary cookie exists for the round trip to Google, to stop anyone signing you in without your knowing. Two measurement cookies join them, but only if you have accepted the audience measurement described just below. No advertising cookie: this site carries no advertising.
Audience measurement
The site can count its visits with Google Analytics, and only if you let it. Until you have answered, or if you declined, nothing is loaded: Google's domain is not even contacted. If you accept, two measurement cookies are set (“_ga” and “_ga_…”, thirteen months), and the pages viewed, the kind of device, an approximate location worked out from your IP address and how the tools are used (a conversion made and its settings, a chart downloaded, a publication, a like, a term searched in the gallery or the colour card) go to Google, which is then a recipient of that data. Never your titles, your comments or your name. Your photograph is never part of it: the conversion never leaves your browser, and Google sees neither your images nor your charts. As for the rest: no advertising pixel, no social network button, and the fonts are served from this server rather than by Google Fonts. You can change your answer further down this page.
Posts' figures
Each member sees, on their dashboard and nobody else does, how many times their posts were viewed, downloaded and shown in the site's lists (gallery, home page, profiles, thread pages). These are counters and nothing more: opening a piece's page, downloading its chart or seeing its card go by adds 1 to that piece's figure for the day, and that is all that is written. No cookie, no IP address and no identifier is recorded, and nothing tells who looked at what. So as not to count the same person twice, the server holds in memory, for half an hour at most, an encrypted fingerprint of the address and browser that it cannot read back, and forgets it whenever it restarts; likewise, so that nobody can inflate the figures by downloading in a loop, it counts at most 10 downloads a day per person, holding until midnight (UTC) an encrypted fingerprint of the address, and of the account if you are signed in (the download itself is never blocked); your browser remembers on its side, for as long as the tab is open (“ptd.viewed”, session storage), the pieces already opened. Robots are not counted, and neither are your own pieces: not while you are signed in, and not from a browser you have signed in on before, which keeps your member number for that (“ptd.members”, local storage, on your device only). None of this goes through Google, and none of it depends on your answer about audience measurement.
How long
Your account, your profile photo and what you have published stay for as long as you keep them; “Remove my photo”, in your account's settings, erases the photo at once. The history of your charts is deleted automatically after six months, entry by entry, without asking. Sessions expire after 180 days. The lines of your activity (who commented on your pieces, replied to you or stitched one of your charts, and the milestones reached) are deleted after 90 days. Posts' figures stay for as long as the post exists, and go with it. The measurement cookies, if you accepted them, last thirteen months, and clearing them resets their count. The server logs of the host that runs this site hold IP addresses for a few days, as any web server does, for diagnosis and security.
Your rights
You can ask for a copy of what the site holds about you, for it to be corrected, or for all of it to be deleted: account, posts and comments. Write to the address below and it will be done. You can also do all of it yourself without writing to anyone: “Delete my account”, at the foot of your account's settings. It is immediate and permanent. You can also withdraw this site's access at any time from your Google account settings.
