Privacy Policy — Wood Block Puzzle

This Privacy Policy describes how the mobile game Wood Block Puzzle ("the App", "we", "us"), published by PlayBrain, handles information when you play. The App is a single-player offline block puzzle. We collect no personal data at all.

The short version

• No account, sign-in, name, email, or any personal detail is needed to play — or accepted.
• Your progress is saved on your device. If you are signed in to Google Play Games, a copy is also backed up to your own Play Games account (Google's Saved Games) so it can be restored. We cannot read it.
• We do not collect raw exception messages or stack traces. Limited diagnostics and optional gameplay recording in updated versions are described in the notice above.
• We send anonymous gameplay analytics to our own server, described below.
• The App shows Google AdMob adverts: a short full-screen advert between Adventure levels, and the rewarded videos you choose to watch.
• The App sells optional in-app purchases through Google Play. We never see a card number, a name or an address.

What is stored on your device

The App saves the following to your device's local storage:

• your best score,
• the run you are in the middle of — which squares are filled, the three pieces waiting in the tray, your current score and your combo streak,
• your coins, the wood themes you own, your amber and your boosters,
• which in-app purchases you own, so the game knows what to give you,
• whether you have muted the sound,
• the analytics identifier and the queue of events waiting to be sent, described in the next section.

Everything above is deleted when you uninstall the App. If you are signed in to Google Play Games, a copy of your progress is also backed up to your own Play Games account (Google's Saved Games) so it can be restored on a new phone or after a reinstall. Google keeps that copy under its own privacy policy and you can delete it from the Play Games app; it is not sent to us and we cannot read it. We do not collect names, email addresses, contacts, location (other than the country, described below), photos, or health data. We have no way to identify you.

What is sent to our own servers

The App sends anonymous gameplay analytics to a server we run at playbrain.games. It is how we find out whether the game is being played and where people stop.

What is sent:

• a random identifier the App generates for itself on first launch, so one installation can be told apart from another, plus a second random identifier for the current session,
• gameplay events: first launch, sessions and screens, boards started, finished, failed or abandoned, in-game currency earned or spent, optional adverts offered and how they ended, whether a break advert was due and how it ended, the shop and purchase steps, features used, whether the rating prompt was shown or skipped, the sheet offering our other games being opened or clicked through, and taps the game refused,
• the install source: whether the install came from a Google ad, the Play Store, another PlayBrain game, or elsewhere, plus the ad campaign name (never the ad click identifier), sent once after install,
• reminder events: the game offered to send you reminders; whether you said yes or not now to that offer; whether your phone allowed notifications when asked; a reminder was set, what kind and how many hours away; and you opened the game from a reminder,
• advert earnings: when an advert is shown, what it earned us as reported by the advert network (the advert type, the amount, its currency and how precise the network says that amount is). This is the advertiser's payment to us, not anything you pay,
• the country you are in, which our server works out from your network address when the App first reports; the address itself is not stored,
• the app version and the platform.

What is never sent: your name, email or any account (the App has none), your advertising ID or any hardware identifier, your location (beyond the country our server works out, described above), anything you typed, or your contacts, photos and files. Nothing about a payment is sent either: the purchase events record only a product identifier our own code chose, such as amber_small, and whether the purchase finished, with no price, currency, country, transaction id, receipt or card detail.

That random identifier is not linked to you, is not shared with anyone, is not used for advertising, and is discarded when you uninstall. Events are queued on the device and sent in batches over HTTPS, so playing offline loses nothing. To stop collection, uninstall the App; to ask for deletion, email [email protected].

Advertising (Google AdMob)

The App includes Google's Mobile Ads SDK and shows two kinds of advert. Rewarded video plays only after you press a control that says AD and names what it gives you: undo a move, show a move, deal three new pieces, more moves, clear space and keep playing after a run ends, double your score, double today's amber, or bring back a lapsed streak. Starting a new game is always free.

A short full-screen advert (an interstitial) may play on the tap that leaves a cleared Adventure level, never during a level and never in Classic or the daily. It is capped: nothing before your third cleared level, then at most one every second level, at least 90 seconds between two of them, nothing in the first minute of a session, and at most ten in a session. The caps are fetched from our server at each launch and are range checked, so they always stay within fixed limits.

The interstitial is not asked for, so the App does request adverts while you play even if you never press a control marked AD. It stops entirely if you buy "No breaks between levels". No purchase removes a rewarded video: those are things you asked for.

When an ad is requested, Google may collect:

• your device's advertising identifier,
• device information (model, operating system, language, coarse region),
• your IP address,
• interaction with the advert (views, taps).

All adverts may be personalised where the law allows it. In the EEA and the UK this follows the choice you make on Google's consent form, and you can turn personalisation off at any time in your device settings (Settings → Privacy → Ads).

If you are in the EEA, the UK or Switzerland, Google's consent form is shown before any ad is ever requested, and nothing is requested until you have answered it. If you decline, no ad is loaded. Taking back a move and dealing new pieces then simply become free, because withholding them would make them a reward for consenting; the two that change a finished run are hidden instead. The game itself is unaffected either way.

Google's handling of this data is governed by its own policies: Google Privacy Policy and How Google uses information from sites/apps that use its services.

You can reset or delete your advertising identifier at any time in your device settings (Android: Settings → Privacy → Ads).

In-app purchases

The App sells a small number of optional items through Google Play Billing: packs of amber (the currency that buys the three boosters), a one-time starter kit, a booster bundle, and a one-time purchase that removes the advert between levels.

Nothing in the game is locked behind a purchase. Every level, every mode and the daily board are free, amber also arrives free from the daily gift and from every rank, and the wood themes are bought with coins you earn by playing and are not for sale.

We never see your payment details. Google Play takes the payment, and we never receive your card number, your name or your address. The App stores only which items you own.

Audio and the microphone

The App plays sound and music. It does not record audio and has no microphone access. The RECORD_AUDIO permission that the audio library would otherwise request is explicitly blocked, and is absent from the App's manifest.

Children

The App is not directed at children under 13, and we do not knowingly collect any data from them. If you believe a child has provided personal information, contact us and we will address it — though note the App has no mechanism to receive personal information in the first place.

Your rights

Because we hold no data about you, there is nothing for us to export, correct or delete. To remove everything the App has stored, uninstall it or clear its storage in your device settings. For advertising data held by Google, use the controls linked above.

Changes to this policy

If the App's data practices change — for example if a different ad format or an analytics tool is ever added — this policy will be updated before that version ships, and the date above will change.
