Gameplay diagnostics and optional session recording

In updated versions that include diagnostics, we collect crash categories and a short code-location fingerprint to identify bugs. We do not send exception messages, stack traces, account details or anything you type.

If you choose to allow gameplay recording, PlayBrain can reconstruct a sample of your play using screen changes, taps, timing and game state. This is not video or audio recording. Nonogram captures puzzle marks and Idle Tycoon captures business and currency state. Other games provide action timelines. Recordings use a random session identifier, not your advertising ID.

Recording is off until you allow it. Change your choice in Settings, Gameplay recording. Declining does not affect gameplay, rewards or purchases. Each capture lasts at most ten minutes. Captures become unavailable after seven days and are deleted during our daily cleanup. We use our existing backend, not a third-party session-recording service.

Your choice and at most one pending recording are stored on your device. Recordings are encrypted in transit and available only to our private review tools. We use them to identify bugs and confusing gameplay, not for advertising or tracking across apps.

The short version

  • There is no account and no sign-in. We never ask who you are.
  • Your puzzle progress, your leaves and your settings are stored on your device. 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. We cannot read it.
  • Apart from that backup, two things leave your device: anonymous gameplay analytics we collect ourselves, and Google AdMob when it requests an advert.
  • There are three kinds of advert: rewarded videos you choose by pressing a control marked AD, a banner at the foot of the board screen while you play a level, and a short full-screen advert when you leave a finished level. The banner and the full-screen advert are not asked for, and both stop if you buy "No breaks between levels".
  • There are optional in-app purchases: packs of berries, a bundle of boosters, a starter basket, and removing the banner and the full-screen advert. Google Play handles the payment and we never see your card or billing details.
  • The game is not directed at children under 13.

What is stored on your device

All of this is stored on your phone and is removed when you uninstall the app. None of it is sent to us, apart from the analytics events described in the next section. 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; we cannot read it.

  • pandanook.save.v1: which puzzles you have solved, the board you are part way through, your daily run and the date of your last daily puzzle.
  • pandanook.wallet.v1: your leaves and berries balances and which nook themes you own.
  • pandanook.muted.v1, pandanook.nomusic.v1 and pandanook.novibrate.v1: your sound, music and vibration settings.
  • pandanook.reminders.v1: whether you switched the daily reminder on.
  • pandanook.review.v1: how long you have played and whether the app has already asked you to rate it, so that it does not ask again.
  • pandanook.telemetry.device.v1 and pandanook.telemetry.queue.v1: a random identifier for this install, and any analytics events waiting to be sent.

What is sent to our own servers

The app sends anonymous gameplay analytics to a server we run at playbrain.games. It is switched off during development and on the web, and it is used to understand which puzzles people finish and where they stop, not to identify anybody.

The identifier attached to those events is a random value generated on your device the first time the app runs. It is not your advertising id, not your hardware id, and not tied to any account, because there is no account. Uninstalling the app destroys it, and a reinstall is a new install to us.

The events are:

  • first_open, session_start, session_end and first_interaction: that the app was opened, and how a session went.
  • install_attribution: where this 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.
  • screen_view: which screen you are on.
  • level_start, level_complete, level_fail and level_abandon: which puzzle, and how it went.
  • ad_offered, ad_load_result, ad_result, ad_offer_shown, ad_offer_hidden and ad_reward_granted: that a rewarded advert was offered, and how it ended.
  • interstitial_check, interstitial_shown and interstitial_result: whether a full-screen advert played between levels, and how it ended.
  • ad_revenue: what one advert earned, as reported by the ad network (the advert type, the amount, its currency and how precise the network says that amount is).
  • currency_earned, currency_spent and currency_blocked: in-game currency earned and spent.
  • feature_used and action_blocked: which features are used, and what the game refused.
  • iap_store_open, iap_offer_shown, iap_purchase_start, iap_purchase_result, iap_restore_start, iap_restore_result, iap_entitlement_changed and iap_unavailable: the shop being opened, what was offered, and how a purchase or restore ended.
  • review_prompt_shown and review_prompt_skipped: whether the rating prompt appeared.
  • reminder_offer_shown: the game offered to send you reminders.
  • reminder_offer_result: whether you said yes or not now to that offer.
  • reminder_permission_result: whether your phone allowed notifications when asked.
  • reminder_scheduled: a reminder was set, what kind and how many hours away.
  • reminder_opened: you opened the game from a reminder.
  • cross_promo_open and cross_promo_click: whether our other games were looked at.

Properties are limited to values chosen by the app, such as level number, board size, daily or campaign mode, hint count, ad outcome, placement, the name of a board theme, and the name of an in-game currency. Leaves are a play currency only and cannot be bought. Berries can be bought, and a purchase is recorded as a product identifier such as pandanook.berries_small together with a price tier, which is a code-chosen bucket name such as t1. A tier is not a price. No amount of money, no card number, no billing address and no receipt is ever collected or sent.

That is the complete list. There is no free-text field, so nothing you type can reach us, and the app never sends the contents of a puzzle or anything about your device beyond the platform it is running on.

Our server also records the country you are in, which it works out from your network address when the app first reports; the address itself is not stored.

Advertising

Adverts come from Google AdMob, and there are three kinds. Rewarded video plays only after you press a control marked AD: Find Panda, Hint, Mark Xs, the revive when your three leaves are gone, the doubled reward on a win, and the streak rescue.

A banner sits in a strip at the foot of the board screen while you are playing a level, and nowhere else: not on the home screen, not on the trail, not on the daily gift page and not in the shop. A new player sees nothing in it until a level has been finished or about three minutes have been spent in the session, whichever comes first.

A short full-screen advert (an interstitial) may play when you leave a finished level, never during one. The cadence is capped: nothing before your third finished 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 banner and the interstitial are not asked for, so the app does request adverts while you play even if you never press a control marked AD. Both stop entirely if you buy "No breaks between levels". Buying something never removes a rewarded advert. Your consent choice can be changed at any time from Settings, Privacy options.

Google and its advertising partners may process device or other identifiers, diagnostics, approximate location derived from an IP address, and ad interaction data to deliver, secure, and measure ads.

Before the advertising SDK starts, the app asks Google's consent tool whether consent is needed where you are, and shows the form if it is. Declining personalised ads or having no advert available does not block play. All adverts, including the banner and the interstitial, 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).

Google acts as an independent controller of the data it collects through those adverts, and its handling of it is covered by Google's own policy. We never receive your advertising id.

Daily reminder

The settings menu has a Daily reminder switch, off until you turn it on. Turning it on is the only thing that asks Android for permission to post notifications; nothing asks at launch, and turning the switch off cancels everything queued. The reminders are local notifications, scheduled on your device by your device. There is no server, no push service and no account: nothing about you leaves the phone for them, and we cannot tell whether one was ever shown. They say only that your daily gift is ready, or that there are boards still waiting. If you revoke the permission in Android's settings, the switch turns itself back off the next time you open the app.

What the app does not do

  • No account, no email address, no password, no sign-in.
  • 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.
  • No push notifications. The only notification is the optional daily reminder above, and the app asks for permission only when you switch it on.
  • No location (other than the country, described above), no contacts, no photos, no microphone. The app plays sound and never records: the microphone permission is explicitly blocked, along with storage, media and the permission to draw over other apps.
  • No selling or sharing of personal information, because none is collected.

Deleting your data

Uninstalling the app removes everything it stored, including the random analytics identifier. Events already sent are anonymous and not linked to you, so there is nothing tied to a person for us to delete. If you would like the events from a particular install removed, write to us at the address below with the install id, and we will delete them.

Children

Panda Nook is not directed at children under 13 and we do not knowingly collect information from them. There is nothing in the app that asks a player for personal information.

Changes to this policy

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