Privacy Policy for Logic Trio

Last updated: 27 October 2026

Logic Trio is made by Nimbleknot. This policy explains, in plain language, what information the game handles and who receives it.

The short version

Logic Trio does not ask you for anything. It has no account of its own: no sign-up, no name, no email address and no password. Since version 1.0.5 you can choose to sign in to Google Play Games, Google's own games service, so that a copy of your progress is kept for a reinstall or for your other phones. You never have to, and the game works the same without it. If you already use Google Play Games on your phone, Google signs you in by itself; see Google Play Games. You can install the game, play it for years and never type a single personal detail into it, because there is nowhere in the game to type one. (An optional feedback form opens in your browser; see Contact.)

Nimbleknot does not run a server and does not keep a database, and the game never sends Nimbleknot your name, your email address or your precise location. (If you write to Nimbleknot yourself, your message carries your email address; see Contact.)

Your puzzle progress stays on your phone. If you sign in to Google Play Games, a copy is also kept in your own Google account, and since version 1.0.6 your stars go to Google as Play Games achievements, and your best streak, your number of gold days and, since version 1.0.8, your times on today's page, your gold days this week, your number of stars and your number of practice levels solved go to Google's leaderboards, where other players may see them beside your gamer name (see Google Play Games).

What the game does contain is advertising, analytics and crash reporting from Google, and those Google libraries collect some technical information automatically. That is what the rest of this policy is about.

What stays on your phone

All of this is stored on your device, and Nimbleknot cannot read it:

If you sign in to Google Play Games, a copy of your progress (the first three items above, not your settings, reminders or the diagnostic log) is also kept in your Google account; see Google Play Games.

If you have Android's automatic backup switched on, your phone may copy this save file to your own Google Drive, the same way it backs up your other apps. That backup belongs to you and sits in your Google account. Nimbleknot has no access to it. You can turn it off in your phone's own settings.

You can erase all of it at any time: Me → Settings → Delete my data. That removes the save completely and, while you are signed in to Play Games, the copy in your Google account. The game becomes new again. Uninstalling the app also removes the save from the phone, but not the copy in your Google account. Since version 1.0.2, the same button also clears the Analytics records still waiting on the phone to be sent and gives the game a new random app-instance ID, so what the game sends afterwards is not joined to what it sent before. Records already sent are deleted on the schedule under How long it is kept. The button does not change your advertising ID or the random installation ID used for crash reports and the game's settings, and it does not switch Analytics off: where you were asked, your consent answer decides that.

What Google's libraries collect automatically

Logic Trio uses five Google libraries that collect information. Each one sends what it collects to Google's servers; Nimbleknot has no server of its own. What Nimbleknot can see of it afterwards, in its own Google accounts, is set out under Where the information goes. Three more Google libraries are in the app and are described at the end of this section: the billing library, which has nothing to sell, the review library, which shows Google Play's own review sheet, and the update library, which asks Google Play whether a newer version of the game is out.

Google AdMob (advertising)

Logic Trio is free and is paid for by ads. To show them, Google's advertising library collects and shares:

Google uses these to choose which ads to show, to measure them, and to detect fraud. All of it is encrypted while it travels.

Google Analytics for Firebase (understanding how the game is played)

This tells Nimbleknot how the game is used, so it can be improved. It collects an app-instance ID, your advertising ID, an approximate location from a masked IP address, and records of what happened in the game — which puzzle you opened, how long it took, whether you used a hint, which ad you were shown.

These records describe the game, not you. Logic Trio deliberately never sets a user ID, and where it summarises a player it uses ranges — "between three and six solved", not the exact number — or a simple setting such as which theme is chosen, so that no summary can be traced back to a single person.

Where you were asked to consent, this collection follows your answer — not just the advertising. If you refused, Logic Trio does three things rather than one: it tells Google you refused, it switches this collection off, and it throws away what is still waiting on the phone to be sent and resets the app-instance ID. What had already been sent before you refused cannot be called back by any app: Google Analytics deletes it after 14 months (see How long it is kept). Nothing further is recorded unless you change your answer at Me → Settings → Your data → Privacy choices, and saying yes later is the only thing that turns it back on — travelling to a country where the question is not asked will not undo a refusal. Where no law requires the question and you were never shown the form, this collection runs as described above. In the US states listed under If you live in the United States, opting out of selling and sharing keeps these records out of Google's advertising but does not switch them off.

Firebase Crashlytics (crash reporting)

When the game crashes, this sends Google a report containing the technical details of the crash, your device model and Android version, and a crash-installation identifier. Logic Trio attaches nothing else — no custom information, no identifiers of yours. This exists so that a crash affecting you can be found and fixed.

Firebase Remote Config (settings without an update)

This lets Nimbleknot adjust numbers in the game — how often an ad appears, how many hints something gives — without publishing a new version. To do that it sends your country, language, time zone, Android version and the app's own identifiers.

Google Play Games (optional sign-in, cloud save, achievements and leaderboards)

Since version 1.0.5 the app contains Google's Play Games library. It lets you keep a copy of your progress in your own Google account, so that a reinstall, or another phone signed in to the same account, gets your progress back. Since version 1.0.6 it also carries the game's achievements and its leaderboards, described below. Using it is your choice, and every puzzle works the same without it.

How you are signed in. Each time the game starts, Google's library asks Google whether this phone is signed in to Google Play Games. If you already use Google Play Games on the phone, Google signs you in by itself a moment after the game opens, and may show its own short welcome banner at the top of the screen for a few seconds. If you do not, the game never asks you when it opens: a Play Games row on the Me page, and a Sign in button on the Ranks page, let you sign in when you choose, and Home may show the line Keep your progress · Play Games once. If you have no Play Games profile yet, Google's own sheet offers to make one there, with a gamer name it suggests, and it may let you change that name. Like the review sheet below, that sheet is Google's, and what you choose there goes to Google. On a phone without Google Play services, none of this appears. If you would rather not use it at all, you can sign out of Play Games in Google's own settings, and the game then keeps your progress on the phone only.

What the game receives. Once you are signed in, Google tells the game your Play Games player ID and your gamer name. The game shows the name on the Me page and uses the ID to tell two players apart on a shared phone, so that one player's progress is never mixed into another's. Neither is sent to Nimbleknot.

The copy of your progress. While you are signed in, the game saves a copy of your progress with Google Play Games: which puzzles you have solved, your best times and your stars, your streak, your freezes and hints, your gold days and your monthly trophies. Your settings, your reminders and the diagnostic log are not copied. Google keeps the copy in a hidden app folder of your Google account's Drive storage, which only Logic Trio can open, on a phone signed in to your account. It does not appear among your Drive files. When you sign in on another phone, or after a reinstall, the game fetches the copy and combines it with what that phone already has.

Achievements and leaderboards (since version 1.0.6). While you are signed in, the game works out your stars from your own progress on the phone and tells Google which achievements you have earned and how far you are towards the next ones. It also sends two numbers to Google's leaderboards: your best streak and your number of gold days. Since version 1.0.8 it also sends, for each of the three puzzles of today's page, the time of your first solve when you used no hint and no check, with that page's date, to the daily race leaderboards, and three more numbers: your gold days this week (with that week's number), your number of stars and your number of practice levels solved. Nothing else goes with them: no moves, no board, no hint. Google keeps them with your Play Games profile. Other players may see your gamer name, your picture and these numbers on Google's leaderboards and on the game's own Ranks page; who can see your profile and your achievements is set by your own Play Games profile settings, which are Google's. An achievement, once earned, cannot be taken back by the game. When you are not signed in, nothing is sent, and the Stars tab of the Ranks page still shows your stars from your progress on the phone.

The Ranks page. While you are signed in, the Boards tab asks Google for the best 100 players of each leaderboard, with their gamer names and pictures, and for your own place. The game shows them on that page only. It keeps the pictures until the game is closed, stores none of it on the phone and sends none of it to Nimbleknot.

What Google receives. Google Play Games is Google's own service, covered by the Google Privacy Policy. Besides your gamer identity, the copy of your progress, your achievements and your leaderboard scores, Google's library sends Google its own analytics and diagnostics, which Google says it uses to keep the library stable and to improve its products. All of it is encrypted while it travels. Nimbleknot runs no server and receives none of it: it cannot see your player ID or your copy, and it sees your gamer name and your scores only where Google's leaderboards show them to every player. Whether a sign-in, a copy, or the sending of your achievements and scores worked is recorded with the game's other Analytics records, described above, without your player ID or gamer name. Since version 1.0.6 your achievements and your scores are added to your Play Games profile, as described above; what other people can see of it is set by your own Play Games settings.

Deleting it. Me → Settings → Delete my data also deletes the copy in your Google account while you are signed in to Play Games on that phone. If the phone is offline at that moment, the game deletes the copy at a later start, once it can. Another phone signed in to the same account keeps its own progress and puts a copy back the next time it is used, so use Delete my data on that phone too. Delete my data does not remove the achievements you earned or your leaderboard scores: Google gives a game no way to take them back. Your Play Games profile settings let you delete Logic Trio's Play Games data on its own, or your whole Play Games profile with everything Google keeps for it; Google explains how, and what each removes, in Delete your Play Games data or Play Games profile.

Google Play Billing (the one purchase: Remove Ads)

Since version 1.0.9 the game offers one optional purchase, Remove Ads: a single payment, made once, that switches the advertising off for good on that Google account. Nothing else is for sale, and nothing in the game needs it.

The purchase is made through Google Play, in Google's own payment sheet. Your card, UPI or other payment details go to Google and are handled under Google's Privacy Policy; Nimbleknot never sees them.

When the game starts, it asks Google Play whether the Google account signed in to the Play Store owns Remove Ads, so that a purchase made on another phone, or before a reinstall, still counts. That exchange is between your phone and Google Play. The game keeps one note on your phone, that Remove Ads is owned, and sends it nowhere.

Google Analytics for Firebase (above) also records that the purchase screen was opened and how it ended (bought, cancelled, pending, restored or refunded), with the item's name, and on Android it records a completed purchase with its price and currency by itself. This is purchase history in Google Play's Data safety terms, used to understand how the game is played and never shared beyond Google.

If you buy it, Google gives Nimbleknot an order record in its Google Play Console: an order number, the item, the price, taxes and fees, the date, the order's history (for example a refund) and your country. Nimbleknot can find an order by the buyer's email address only if you give it that address, for example when you write to ask for help with a purchase. Nimbleknot uses order records only to keep its accounts and to help with a purchase you ask about, and does not use them for anything else or pass them to anyone.

Google Play In-app Review (rating the game)

After a good day the game may ask Google Play to show you its review sheet — Google's own panel, with a star rating and a box you can write in. It is worth being clear about this one, because it is an exception to everything above: apart from Google's own Play Games sheet, described above, it is the only place inside Logic Trio where there is anything to type into. (The feedback form under Contact opens outside the game, in your browser.)

Google decides whether that sheet actually appears; the game only asks, and Google often declines. If it does appear, you are never obliged to use it, and closing it changes nothing in the game.

What you write there does not go to Nimbleknot — it goes to Google Play, and it is published publicly on the Logic Trio store page, under the name and picture of the Google account you use on the Play Store, exactly like any other Play Store review. That is how Play Store reviews work everywhere; it is mentioned here so that nobody is surprised by it.

Google Play In-app Updates (checking for a newer version)

Since version 1.0.3 the app also contains Google Play's in-app updates library. When the game starts, and each time you come back to it, it asks Google Play whether a newer version of Logic Trio is available. To answer, Google Play collects device metadata, the version of the game on your phone and the list of its installed modules and asset packs. Google says it uses these to work out whether an update is available and how large it would be, that the data is encrypted, that it is not passed to any third party, and that it is deleted after a fixed period.

That exchange happens between your phone and Google Play, the store the game was installed from. Nimbleknot receives nothing from it. If a newer version is waiting and your phone has not updated by itself, Home may show one line, An update is ready. A tap opens Google Play's own update sheet. You can decline there and play on. That the line was shown or tapped is recorded with the game's other Analytics records, described above.

What Logic Trio never collects

Your choices

Where the information goes

The information described above goes to Google, which processes it as the advertising and analytics provider. Google's own handling of it is covered by the Google Privacy Policy and, for advertising, How Google uses information from sites or apps that use our services.

Advertising does not stop at Google, and you should know that plainly. AdMob sells the advertising space by auction, so when an ad slot is filled, a request describing the opportunity — your advertising ID, an approximate location from your IP address and your device type — is offered to the advertising companies bidding for it. Those companies are Google's advertising partners, there are a few hundred of them, and the list changes as Google adds and removes them. Nimbleknot does not choose them individually and receives nothing back from them.

In the European Economic Area, the United Kingdom and Switzerland, you can see every one of them by name and refuse them one at a time. On the consent form Logic Trio shows there, Manage options lists each partner with what it collects and how long it keeps it, and each has its own switch. You can also reopen that form at any time from Me → Settings → Your data → Privacy choices.

Selling and sharing, in the sense US law gives those words. Nimbleknot is paid for showing ads, not for handing over information about you, and it holds nothing from the game that names you. But the auction described above passes your advertising ID, an approximate location and your device type to advertising companies so that they can bid to show you an ad. The privacy laws of California and several other US states count that as "selling" or "sharing" personal information, and as "targeted advertising". Logic Trio therefore treats it as exactly that. If you live in the United States, below, sets out what is involved and gives you a way to opt out. What reaches Nimbleknot itself is the Analytics records and crash reports described above, in its own Google Analytics and Firebase accounts, filed under random IDs. Nothing described here tells Nimbleknot who you are.

How long it is kept

Nimbleknot keeps no other copy of any of it.

If you are in the European Economic Area, the United Kingdom or Switzerland

European data protection law (the GDPR, the UK GDPR and the Swiss Federal Act on Data Protection) gives you some extra information and rights.

Who is responsible. The developer named on the game's Google Play listing, trading as Nimbleknot, decides what the game collects and why. Google provides the Analytics, crash-reporting and Remote Config services the developer uses. For advertising, Google also decides some uses of the data itself, under its own privacy policy. Where the developer lets Google use Analytics data to improve Google's own services, Google decides those uses itself as well.

Why each use is allowed:

Information sent outside Europe. Google may process this information in the United States and in other countries. It relies on the EU–U.S. Data Privacy Framework and its UK Extension, the Swiss–U.S. Data Privacy Framework, and the European Commission's standard contractual clauses.

Your rights. You can ask for access to the information held about you, and for it to be corrected, deleted, restricted or given to you in a portable form, and you can object to the uses based on legitimate interest. The records are filed under random IDs rather than your name, so the developer can act on them only where they can be matched to you; Delete your data explains what that means in practice. Write to nimbleknot.games@gmail.com. You also have the right to complain to the data protection authority where you live or work: in the UK, the Information Commissioner's Office; in Switzerland, the Federal Data Protection and Information Commissioner.

If you live in the United States

California, Colorado, Connecticut, Delaware, Florida, Indiana, Iowa, Kentucky, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, Oregon, Rhode Island, Tennessee, Texas, Utah and Virginia have consumer privacy laws. Whether each one reaches a developer of Nimbleknot's size differs from state to state, so Logic Trio gives players in all twenty the choice and the rights below.

Opting out of selling, sharing and targeted advertising. When Google's systems place you in one of those states, Me → Settings → Your data has a row called Do Not Sell or Share My Personal Information. It opens Google's page My data preferences: choose Don't sell or share my data and tap Save and close. From then on:

Your choice is stored on your phone. You can open the row again at any time and change it back by choosing Allow the sale or sharing of my data. Delete my data does not remove it. Uninstalling the game, or clearing its storage in Android's settings, does, so opt out again after a reinstall.

Other ways to opt out, wherever you are. The row appears only where Google's systems detect one of those states. On any phone you can also delete your advertising ID (Android → Settings → Privacy → Ads). After that, ads in Logic Trio and in every other app can no longer be personalised to it.

Global Privacy Control. Logic Trio is an app, not a website, and Android does not pass the Global Privacy Control signal to apps. If Google's consent tool ever records one for your phone, Logic Trio treats it as an opt-out: it asks only for ads that are not personalised, and it keeps its Analytics records out of Google's advertising.

What is collected, and who receives it. Since the game was released, Logic Trio has collected the following, all of it automatically from your phone through the Google libraries described above:

This is used to show ads and measure them, to understand how the game is played so that it can be improved, to find and fix crashes, and to adjust the game without an update. Google also uses the advertising data to detect fraud. How long each part is kept is set out under How long it is kept.

Logic Trio collects no name, contact details, payment details, precise location, or anything else the law treats as sensitive personal information. If you buy Remove Ads, Nimbleknot receives the order record described under Google Play Billing. It does not use your information to make decisions about you that have legal or similarly significant effects.

Players under 16. Logic Trio does not ask your age, so Nimbleknot has no actual knowledge that it sells or shares the personal information of anyone under 16. The game is made for players aged 13 and over.

Your rights. Depending on your state, you can ask to know what personal information is held about you and to receive a copy of it, to have it corrected, and to have it deleted. You can opt out of its sale, sharing and use for targeted advertising, as described above. Nimbleknot will never treat you differently for using any of these rights: the game does not change.

How to ask. Write to nimbleknot.games@gmail.com with "US privacy request" as the subject. Someone you have authorised can write for you, and Nimbleknot may ask them to show your permission. You will get an answer within 45 days. If the law allows longer and more time is needed, you will be told so within those 45 days.

What can and cannot be done. The records are filed under random IDs that the game never shows, and nothing links them to a name or an email address. So an email cannot be matched to your records, Nimbleknot cannot verify that any record is yours, and it will not claim to have found or deleted something it could not find. What does work is set out on Delete your data: Delete my data in the game erases the game's own data on your phone, deleting your advertising ID cuts the link to it, and the opt-out above applies your choice about selling and sharing.

If the answer is no. If Nimbleknot turns down your request, you can appeal: reply to the answer with the word "appeal". The request will be looked at again and answered, with reasons, within 45 days. If you are still not satisfied, you can contact your state's Attorney General, and in California also the California Privacy Protection Agency.

Children

Logic Trio is made for players aged 13 and over and is not directed at children. The game is not enrolled in Google Play's Families programme, contains no content aimed at children, and is not tagged as being for users under the age of consent. If you believe a child under 13 has used the game and that information was collected, write to nimbleknot.games@gmail.com and it will be dealt with.

Changes to this policy

If this policy changes, the date at the top changes with it and the new version appears at this same address. Changes that expand what is collected — such as switching on an in-app purchase — are made before the change reaches players, never after.

Contact

Nimbleknot — nimbleknot.games@gmail.com

Email. A message you send to this address reaches Nimbleknot's mailbox with your email address and whatever you choose to write. It is kept there and read to answer you and to fix what you report. What testers report may be summarised, without names or addresses, when Nimbleknot reports on its testing to Google Play.

Feedback. Me → Settings → Send feedback opens a short Google Form in your browser. It asks for no name and no email address; what you type goes to Nimbleknot's Google account, where it is read to improve the game and may be summarised, without names, when Nimbleknot reports on its testing to Google Play. Please do not put personal details in it.
