Privacy Policy for Logic Trio

Last updated: 22 September 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. There is no account, no sign-in, no name, no email address, no profile and no password. You can install the game, play it for years and never type a single personal detail into it, because there is nowhere to type one.

Nimbleknot does not run a server, does not keep a database, and never receives your name, your email address or your precise location.

Your puzzle progress stays on your phone.

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 only, and Nimbleknot cannot read it:

• which puzzles you have solved, your best times and your stars
• your streak, your freezes, your gold days and your monthly trophies
• how many hints you have
• your settings: theme, language, sound, vibration, colour-blind patterns, how you place a crown, and your reminder time
• your daily reminders, which are scheduled and shown entirely by your phone
• a small diagnostic log of what happened in the game — which puzzle was opened, which hint was used — kept on the phone so a problem can be described if you ever report one, and cleared with everything else below

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 the game becomes new again. Uninstalling the app also removes it.

What Google's libraries collect automatically

Logic Trio uses four 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. Two more Google libraries are in the app and are described at the end of this section: the billing library, which has nothing to sell, and the review library, which is the only part of the whole game you can type into.

Google AdMob (advertising)

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

• your IP address, which gives an approximate location such as a city or region — never a precise one
• your interactions with ads — that an ad was shown, closed or tapped
• diagnostic information about how the ad performed
• your Android advertising ID and App Set ID — resettable identifiers that belong to your device, not to you personally

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.

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 Billing (in the app, with nothing for sale)

The app also contains Google Play's billing library. A purchase was built and tested during development and then switched off before release, and the library stayed where it was.

When the game starts, it asks Google Play two questions: whether the store is reachable on this phone, and whether the Google account already signed in to the Play Store has bought anything from Logic Trio. The answer is always no, because Logic Trio has nothing for sale — no product exists to buy, and there is no payment screen anywhere in the game to reach. That exchange happens between your phone and Google Play, the store you are already signed in to. Nimbleknot receives nothing from it, no purchase is ever made, and so there is no purchase or payment information about you anywhere.

It is named here because it is genuinely inside the app, and anything inside the app belongs in this policy even when it sells nothing. If anything is ever offered for sale, this policy will be updated before that happens.

Google Play In-app Review (the one place you can type)

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 the single exception to everything above: it is the only place in Logic Trio where there is anything to type into.

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.

What Logic Trio never collects

• your name, email address, phone number or postal address
• any password, payment detail, bank or card information
• your precise location, or GPS of any kind
• your contacts, calendar, photos, files, microphone or camera
• anything you type into the game itself — there is nowhere in Logic Trio to type. The one exception is Google Play's own review sheet, described above: what you write there goes to Google and appears publicly on the store page, never to Nimbleknot
• purchases. Logic Trio 1.0 sells nothing. There is no in-app purchase in this version, so no purchase information exists to collect. If that ever changes, this policy will be updated before it does.
• anything it knows comes from a child under 13. Logic Trio is not directed at children and is made for players aged 13 and over.

Your choices

• Reset or delete your advertising ID. Android → Settings → Privacy → Ads. You can reset the ID, or delete it entirely, which stops ads being personalised to it.
• Choose what ads you see, and whether the game measures you at all. If you live in the European Economic Area, the United Kingdom or Switzerland, where the law requires a choice, Logic Trio shows you Google's consent form the first time you play, and you decide there. You can change your answer later at Me → Settings → Your data → Privacy choices. That row appears only where the law provides it. Your answer is honoured by both halves of the app, not just the ads: refusing switches off the Analytics collection described above as well, and throws away what is still waiting on the phone to be sent; what was already sent is deleted by Google Analytics after 14 months. Refusing does not restrict the game in any way — you keep every puzzle, every feature and every hint, and simply see less relevant ads.
• Erase your game data: Me → Settings → Delete my data.
• Ask about your data. Write to nimbleknot.games@gmail.com. The Analytics records and crash reports are filed under random IDs that the game never shows, not under a name or an email address, so a message cannot be matched to them; Delete your data says plainly what can and cannot be done. Questions are welcome and will be answered.

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.

Where the law gives you a choice, you can see every one of them by name and refuse them one at a time. On the consent form Logic Trio shows in the European Economic Area, the United Kingdom and Switzerland, 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.

Nimbleknot does not sell your information to anyone. What reaches Nimbleknot 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

• Your save, on your phone: until you delete it (Me → Settings → Delete my data) or uninstall the game. A copy in your own Google Drive backup follows your Google account's backup settings.
• Google Analytics records: each record of what happened in the game is deleted after 14 months. Google clears out expired records once a month, so a record can outlast 14 months by a few weeks. The random app-instance ID they are filed under is cleared out the same way once your phone has sent nothing for 14 months. Totals built from them, such as how many players solved Monday's puzzle, describe no single player and are kept.
• Crash reports (Firebase Crashlytics): 90 days, after which Google starts deleting them from its live and backup systems.
• Remote Config: Firebase keeps the random installation ID the game asks for its settings with until the developer deletes it, under Firebase's own terms. Once the game is uninstalled, nothing on your phone carries that ID any more.
• Advertising (AdMob): Google keeps advertising data for the periods set out in How Google retains data we collect. The advertising partners in the auction keep what they receive for the periods each one states; in the EEA, the UK and Switzerland, Manage options on the consent form lists them partner by partner.

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:

• Personalised ads and Google Analytics: your consent, given on Google's consent form. You can withdraw it at any time at Me → Settings → Your data → Privacy choices; withdrawing does not undo what was done before.
• Ads that are not personalised, which is what you see if you refuse: legitimate interest. The ads are what pay for a free game.
• Crash reports and Remote Config: legitimate interest, in finding and fixing crashes and adjusting the game without an update. These run whatever you answer on the form.

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.

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.
