For Oddgrid, the offline odd-tile game for Android
Oddgrid collects no personal data. There is no account, no advertising, no analytics, no crash reporting and nothing to buy; the game requests no Android permissions and never opens a network connection. Your best round and high score live on your handset.
Oddgrid is made and published by AD HOC d.o.o., a company registered in Slovenia, which releases its games under the name CrimsonPine Games. Under the General Data Protection Regulation and Slovenia's Personal Data Protection Act (ZVOP-2), that company would be the controller for any personal data the game processed. It processes none, so the role has nothing attached to it.

Oddgrid is built around how small a difference in shade you can spot, which makes it look like a measurement of your eyesight. It is not one, and it must not be treated as one. It is not a screening tool, not a diagnostic test, and not an assessment of anything: how far you get depends on your screen, its brightness, the light in the room, how tired you are and how much you feel like squinting, at least as much as on your eyes.
A round you cannot beat means the round was hard. If you are genuinely concerned about your sight, see an optician or a doctor — that is a real examination with calibrated equipment, and this is a phone game.
Each round's odd tile differs from its neighbours in lightness rather than colour, so the game does not depend on distinguishing red from green and is playable with the common forms of colour vision deficiency. This is a design note rather than a promise about any individual's sight.
A small file in the game's own private storage, holding scores and settings only:
Nothing in it identifies you: no name, email address, contacts, photos, location, advertising identifier or device identifier. The file never leaves the phone and we never see it.
Your taps are read to decide whether you hit the odd tile and are then gone. No reaction times are recorded, no map of where on the screen you look or tap is built, and no profile of how your performance changes over days exists anywhere — not on the phone and certainly not with us. The score is a number you beat, not a record of your faculties.
Every round's grid size and shade difference come from a fixed rule compiled into the game, so round forty is exactly as hard for everybody. Nothing is adjusted based on how you are doing, because nothing about how you are doing is collected — and because a game about a shrinking difference would be pointless if the difference quietly stopped shrinking.
No advertising library, so nothing plays between rounds, nothing must be watched to continue, and no advertising profile is built from your play. No analytics library and no crash reporter, so no usage events, session logs or crash traces leave the handset. No billing library, so no mode, retry or hint is for sale and no payment data exists. No account, no leaderboard, no sharing.
Oddgrid requests no Android runtime permissions: not camera, microphone, location, contacts, storage or notifications.
None. The whole game is compiled into the download, so it opens no connection to our servers or anyone else's and behaves identically in aeroplane mode. Nothing leaves the handset to be intercepted, and nothing arrives that could change how it behaves after installation.
Installing or updating Oddgrid is a transaction between you and Google, handled under Google's own privacy policy and its agreement with you. What reaches us is the aggregated, anonymous developer console view — installs, ratings, country totals — which identifies nobody.
If a future version ever touches the network, this page is rewritten before that version is published and the change stated plainly.
Oddgrid is a simple visual puzzle suitable for all ages, and children are often infuriatingly good at it. Since nothing is collected from anyone, nothing is collected from children, and there are no adverts, no chat, no sharing, no links out and nothing to buy.
The General Data Protection Regulation and ZVOP-2 give you the right to ask whether your personal data is processed, obtain a copy, have it corrected or erased, restrict or object to processing, and complain to a supervisory authority. Every one of those needs data in our hands, and there is none — we will confirm that in writing if it is useful for your records.
Your scores are removed by resetting them in the game, clearing the app's data in Android settings, or uninstalling Oddgrid. Nothing survives elsewhere, which also means a high score cannot be restored by us or carried to a new phone.
Complaints may be addressed to the Information Commissioner of the Republic of Slovenia (Informacijski pooblaščenec, ip-rs.si) or to the supervisory authority where you live, though a note to us usually settles things sooner.
This page is updated only when the game changes in a way that affects privacy, and the date near the top changes with it. Builds already installed keep behaving exactly as described.
A round that looked impossible, colours that read oddly on your screen, a privacy question: spot@adhoc.rest, read by the person who wrote the game, usually answered within a couple of days. Pišete lahko tudi v slovenščini.
This policy covers the Android application Oddgrid (com.spotlab.oddgrid) and no other software.
