Privacy Policy
Opposites Stick for iPhone and iPad · effective 10 November 2026
I'm Sergey Ilyevsky, the developer of Opposites Stick. The game has no account of its own and nothing to sign up for, and it never asks you for your name, email address, postal address, phone number, location, contacts or photos, and it shows no advertising.
The game itself sends two things off the device, both of them anonymous:
- Usage statistics. Which level you start, how long it takes and how it ends, whether you used a hint, the settings you choose, and whether the full game was bought from the offer (never the price, your account or the payment), so I can see what people play and where they get stuck. No advertising identifier and no IP address are sent. The identifier that groups one player's events is scrambled on the device and again on the server, so neither I nor the provider can tell whose it is, or match it against any other app. Handled by TelemetryDeck.
- Crash reports. If the game crashes, freezes or is shut down by the system, a report describing the failure is sent: the sequence of code that was running, the device model and the iOS version, with a random number made up when the game was installed, so that one device's repeats of a problem can be told apart. Nothing is sent while the game runs normally. No IP address or location is kept, and screenshots and the contents of the screen are switched off, so nothing you see or make in the game is included. Handled by Sentry, on servers in the United States.
Neither is used for advertising or to track you across other apps and websites, and neither is sold or passed to anyone beyond the two providers above.
Game Center and purchases
The leaderboard is provided by Apple's Game Center. If you are signed in to Game Center, the number of levels you have solved goes to it, with your Game Center nickname, handled by Apple under Apple's privacy policy; no personal information reaches me through it.
The full game is bought through the App Store. Apple processes the payment — I never see your payment details, and am told only that a purchase was made.
What stays on your device
Your progress, the solutions you found, your settings and any levels you make are stored on the device itself and are not sent anywhere. Deleting the game removes them.
Keeping and deleting data
Usage statistics are kept as aggregate numbers and are not deleted; crash reports expire on Sentry's own schedule. Either way none of it carries an identifier that can be traced back to a person, so there are no records of yours for me to find, show or delete on request.
To stop the game sending anything at all, turn off Diagnostics under Privacy in the game's Settings.
For players in Europe
European data protection law (the GDPR, and the versions of it in the UK and Switzerland) asks for a few more things to be spelled out.
Who is responsible. I am: Sergey Ilyevsky, an independent developer in Israel, reachable at the email below. The European Commission recognises Israel as protecting personal data adequately.
Why it is allowed. Usage statistics and crash reports are sent on the basis of my legitimate interest in seeing how the game is played, and in finding and fixing what goes wrong in it (Article 6(1)(f) GDPR). Only what those two purposes need is sent, nothing in it identifies you, and it stops as soon as you turn Diagnostics off.
Where it goes. TelemetryDeck is a German company with its servers in the EU. Sentry is in the United States, and is certified under the EU–U.S. Data Privacy Framework and its UK and Swiss extensions, which is what allows data to go there from Europe.
Your rights. The GDPR gives you rights over data about you: to see it, have it corrected or deleted, limit or object to its use, and take a copy. Here they have nothing to work on: nothing the game sends identifies you, so I hold no data I could tell is yours. To stop anything more being sent, turn off Diagnostics: it takes effect at once. If you think I've got any of this wrong, or it could be done better, please write to me: my email address is below. The GDPR also gives everyone the right to complain to their country's data protection authority.
