Privacy policy
Effective
In short: no account is required and there are no ads. Your games stay on your device. Optional Google Analytics loads only after you allow analytics cookies.
What is stored on your device
The game uses your browser’s localStorage to remember:
- your settings (opponent, level, colour, legal-move dots, sound);
- the game in progress, as a list of moves, so you can continue after closing the tab;
- your win/loss/draw record for each computer level.
This data never leaves your browser and is not sent to us. You can delete it at any time by clearing this site’s data in your browser settings. Your analytics choice is also saved locally. If you opt in, Google Analytics uses first-party cookies such as _ga.
Optional analytics
If you choose “Allow analytics”, Google Analytics measures page visits, session activity and technical information such as browser, device and approximate region. Google processes network information to provide this service. We do not enable advertising signals or personalized ads, or send your game history, settings or win/loss record. We remove query strings and fragments from the page and referrer URLs sent to Analytics.
Choose “Reject” to play without Analytics. You can change your choice using “Analytics preferences” in the footer. Rejecting disables further collection and removes this site's Analytics cookies; it does not delete previously collected data. See Google’s privacy policy.
What our hosting provider processes
The site is delivered by Cloudflare. Like any web host, Cloudflare processes technical request data, such as your IP address, browser user agent and the page requested, to deliver the page and protect it against abuse. We don’t use this data to identify or profile visitors. See Cloudflare’s privacy policy.
Replay links
If you copy a replay link, it contains only the moves of the game (for example ?g=f5d6c3). Nothing else about you is included. The move list is read in your browser; it is not stored on our servers.
If you email us, we use your address and message only to reply, and delete correspondence we no longer need.
Children
Playing requires no personal information. If you are a child, leave optional analytics disabled and ask a parent or guardian before opting in.
Changes and contact
If this policy changes, we will update this page and the date above first. Questions: contact@othellogame.app or see the contact page.
