Privacy
The short version: Algodle collects nothing about you. There are no accounts, no analytics, and no trackers. Nothing about who you are, or what you pick, ever leaves your phone.
What stays on your device
Algodle remembers a few small things, and only on your device:
- whether you've seen the welcome card;
- today's problem, so it opens instantly and still works with no connection;
- the pattern you picked for today's problem, so reopening the app shows your answer rather than asking again. Only the latest pick is kept;
- for Mix-ups, each time a pick gets "Not this time": the two patterns, which problem it was, that problem's day, and when. It's kept so that two patterns you've mixed up on more than one problem can be shown back to you, with how to tell them apart. Nothing is kept for "Spot on", "Also works", or "Not sure". A pair is removed when you tap Got it, or when you later get a problem right that offered the other pattern as its trap;
- the text size you chose with Aa, and the speed you chose for playing a solution's steps.
None of it is sent anywhere or associated with you. Picks you make on past days aren't kept, apart from the Mix-ups note above.
Getting the problems
To show you a problem, Algodle asks its server (algodle.cora-branch.com) for
today's problem or the list of past days. This is a one-way request: the app asks for content
and the server sends it back. The app never sends the server your picks or anything else
about you.
Like any website, the server's front door keeps standard request logs, the kind of technical detail every web server records, such as the requesting IP address, the time, and the device type. These are used only to keep Algodle running and secure. They are not used to identify or track you, are not linked to a profile, and are not sold or shared. The part of the server that holds the problems isn't passed your address at all.
No analytics, ads, or tracking
Algodle contains no analytics software, no advertising, and no third-party tracking of any kind. It uses no cookies, and nothing it notes about your picks is kept anywhere but on your own device.
Children
Algodle collects no personal information from anyone, including children.
Changes
If this policy changes, the "Last updated" date above will change with it. Collecting nothing is the point, so any change will be in that spirit.
