Privacy Policy — Block Escape: Color Slide
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.

This Privacy Policy describes how the mobile game Block Escape: Color Slide ("the App", "we", "us"), published by PlayBrain, handles information when you play. The App is a single-player offline sliding-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. Most are optional; a short one may play when you leave a finished level, and a small advert strip sits at the bottom of the puzzle screen on larger displays.
- The App can send you one optional daily reminder, and only if you switch it on in Settings. It is scheduled by your own phone, we run no push service, and nothing about it leaves the device.
- The App offers optional in-app purchases. Google Play handles the payment, and we never see your card or billing details.
What is stored on your device
The App saves the following to your device's local storage:
- the highest level you have reached, and how many you have completed,
- the puzzle you are on — where each block is, your undo history, your move count, hints used, and how many times you have restarted it,
- your music, sound effect and vibration preferences,
- your wallet: sparks, keys, the boosters you hold, which enamel finish you wear, and the high-water marks that stop a reward being paid twice,
- a record of what you have purchased, so a purchase survives a restart.
Your saved progress is stored on your device and is deleted when you uninstall the App. 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 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, 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,
- a session identifier, valid for the time the App is open,
- gameplay events from a fixed list in the App's source: sessions and screens, levels started, solved, lost or abandoned, adverts offered and how they ended (rewarded and full-screen), the shop and purchase steps, features used, the rating prompt, the More games sheet, and taps the game refused,
- in-game economy events: sparks, keys and boosters earned or spent, and which in-game item was bought with them,
- purchase events: which product was shown or bought, as a product identifier such as
blockescape.keys_small, with a price tier (a code-chosen bucket name such ast1). A tier is not a price and no amount of money is ever sent, - 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, anything you typed, your contacts, photos and files, or your card number, billing address, receipt or any payment 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 request deletion, email [email protected].
Rating prompt
The App may occasionally ask you to rate it using Google Play's own in-app review dialog. Google decides whether that dialog actually appears; we only ask. Any rating you leave goes to Google Play, not to us, and we cannot see who left it.
Advertising (Google AdMob)
The App includes Google's Mobile Ads SDK for two optional features: you may choose to watch a rewarded video to be shown the next move on a puzzle you are stuck on, or to skip a level you have struggled with for a long time. Two adverts are not optional. A short full-screen advert (an interstitial) may play when you leave a finished level, never during one, never in your first few levels, and never more often than a fixed cap allows. On screens with the room for it, a small advert strip also sits at the very bottom of the puzzle screen, in its own reserved band, below the Stuck link and never over the board. It is on the puzzle screen only: not the menu, not the gift ladder, not the store, not a panel. Every other advert is behind "Show a move", "Take moves back" or "Skip this level".
The one-off "No breaks between levels" purchase removes both of the adverts you did not choose. The adverts you do choose still work exactly as before: the hint button, the undo button, the skip button, the streak rescue and the doubled daily gift are all still there after any purchase.
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).
The rewarded videos and the full-screen advert request non-personalised ads only, which limits Google to using this data for frequency capping, ad measurement and fraud prevention rather than building an advertising profile of you. The banner strip is requested with the SDK's default settings, so whether it is personalised follows your answer on Google's consent form.
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 and the optional hint and skip are simply unavailable — the rest of the game is unaffected, and every level remains solvable without them.
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 offers optional purchases: packs of keys, a bundle of boosters, a starter kit, and the option to remove the adverts you did not choose. Nothing in the game is locked behind them: all 300 boards are in the App and playable from the first launch, every booster is earnable from the daily gift and from the escape ranks, and the rewarded adverts are unchanged whether you buy anything or not.
Payment is handled entirely by Google Play. We never see, receive or store your card number, billing address, name or receipt. Restore purchases is available in the settings menu and in the store screen, without an account. Packs of keys are consumable: once spent they are gone.
For our own analytics we record which product was shown and which was bought, as the product identifier and a price tier, as described above. We never record an amount of money.
Daily reminder
The Settings sheet has a Daily reminder switch. It is off until you turn it on, and turning it on is the only thing that ever asks your phone for notification permission. The reminder is a local notification: your own phone schedules it and shows it. There is no server, no push token and no account, so nothing about it is sent anywhere. Turning the switch off cancels anything already scheduled.
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.
