PRISMATIC is a puzzle game by Cormorant Wing ("we"). The short version: no account, no ads, no tracking, and nothing that identifies you.
What stays on your phone
Your progress, stars, best scores, daily streak and settings are stored on your phone only, as is anything waiting to be sent (below). Daily reminders are scheduled by your phone and send nothing anywhere. When you share a result, the game hands a picture and a line of text to your phone's own share sheet; it sends nothing itself.
What the game sends to us
The game talks to one server of ours, hosted by Supabase in London (UK), for two things. Neither carries a name, an account, an advertising ID or any other identifier for you or your phone.
Results, for "better than n% of players"
The first time you complete a level or a daily puzzle, the game sends the puzzle's name, how many actions you took and how long it took. It also asks how everyone else did on that puzzle, so it can show your place. Results are kept as anonymous rows so everyone's comparison stays accurate.
Anonymous play statistics
The game counts how it is played: launches, days played, levels started, solved, left, retried and shared, and undos. It also notes how many weeks ago the game was first opened on the phone, in broad bands. It adds these up on your phone and sends the totals when you leave the game and on your first visit to the home screen each day, with the phone's platform (iOS or Android) and the game's version. On our server they are added into weekly totals shared by every player, so nothing in them can be traced to you, your phone or a single session. We use them only to see where the game is too hard, too easy or unclear.
You can turn them off in Settings > Anonymous Stats. While off, nothing is counted or sent.
Your IP address
Every connection to the internet carries one. We store it for one purpose only: to limit how often one address can send results or statistics, so the numbers can't be flooded. Each record covers one hour and is deleted as soon as the next request arrives after that hour: normally within about an hour, longer only if nobody plays in between. Supabase also keeps short-lived request logs, which include IP addresses, for up to 7 days for security and running the service.
If the game can't reach the server (you're offline, say), results wait on your phone until it can, and statistics are simply dropped. The game works fully offline either way.
Game services from Google and Apple
On Android, the game uses Google Play Games to award achievements. If you have a Play Games profile, Google signs you in automatically and the game tells it which achievements you've earned. Google collects your gamer identity, your achievements, and analytics and diagnostics about its own service, under Google's privacy policy. The game never reads your Play Games name or ID, and nothing from Play Games is sent to us.
On iOS, the game uses Apple's Game Center for the same achievements, if you're signed in to it. That data is held by Apple under Apple's privacy policy. The game never reads your Game Center name or ID, and nothing from Game Center is sent to us.
What we don't do
No ads, no advertising or analytics SDKs (our statistics are the ones above), no tracking across apps or websites, no location, contacts, photos or microphone. We don't sell or share anything with anyone; Supabase processes the data above for us, and only on our behalf.
Keeping and deleting
Results and play statistics are kept indefinitely, because they are anonymous and together make the game better for everyone. IP addresses are kept only as described above.
Because nothing we hold is linked to you, we can't find or delete "your" results or statistics: there is no way to tell which ones are yours. You can stop future statistics at any time with the Anonymous Stats setting, and uninstalling the game removes everything stored on your phone. Data held by Google Play Games or Game Center can be managed or deleted in your Google account or your iPhone's Game Center settings.
Under UK and EU data protection law you have rights over personal data about you, including access and erasure. If you have a question or a request, write to us at the address below and we'll answer it.
Children
PRISMATIC is not directed at children under 13, and we don't knowingly collect personal information from anyone.
Changes
If the game starts sending anything new, we'll update this page and the date at the top before the update that does it reaches the stores.
