For Hueflask, the offline colour-sorting puzzle for Android
Hueflask collects no personal data. There is no account, no advertising, no analytics, no crash reporting and nothing to buy; the game requests no Android permissions and never opens a network connection. The sections below explain what that means in practice.
Hueflask is made and published by Sparx Electrical Limited, a company registered in England and Wales, which releases its apps under the name EmberHarbor Digital. Where data protection law refers to a data controller, that company is it — although in practice there is nothing to control, because the game gathers nothing.

Every level ships inside the download, so nothing has to be fetched. To remember where you are, Hueflask writes a small file into its own private storage on your phone:
None of this identifies you. No name, email address, phone number, contact list, photo, location, advertising identifier or device identifier is involved at any point. The file never leaves the phone, and we never see it.
There is no rewarded advert behind a hint, no video to sit through for an extra undo, and no life system that runs out. This matters for privacy as much as for patience: rewarded adverts are the usual reason a puzzle game ends up carrying an advertising SDK, and with no adverts of any kind there is nothing in Hueflask that wants your advertising identifier.
No advertising library, so no adverts are shown and no advertising profile is built from how you play. No analytics library and no crash reporter, so no usage events, session logs or crash traces are gathered or transmitted — we do not know which level you are stuck on or how long you played. No billing library, so nothing can be bought and no payment data exists. No account system and no leaderboard, so nothing you do is visible to anyone else.
Hueflask also requests no Android runtime permissions at all: not camera, microphone, location, contacts, storage or notifications.
None. The whole level set is compiled into the download, so the game opens no connection to our servers or to anyone else's and behaves identically in aeroplane mode. Because nothing is sent, nothing can be intercepted; because nothing is received, no behaviour can be switched on remotely after you install it.
Google, because Hueflask is distributed through Google Play. When you install or update the game, Google processes that under its own privacy policy and its own agreement with you. What reaches us is the aggregated, anonymous figures shown in the developer console — install counts, ratings, country totals — which cannot be traced back to an individual player.
If a future version of Hueflask ever includes anything that touches the network, this page will be rewritten before that version is published, and the change will be described plainly rather than added quietly.
Hueflask is a colour puzzle suitable for all ages. Because it collects no personal data from anyone, it collects none from children either, and there is nothing in it — no adverts, no chat, no sharing, no outbound links, nothing to buy — through which a child could send information anywhere or spend money.
If you are a parent or guardian and something appears to behave differently from what is described here, please write to us and we will look into it straight away.
Under the UK GDPR, and under the EU GDPR where it applies to you, you have rights to access, correct, erase and port the personal data a company holds about you, and to complain to a supervisory authority. Those rights need data to act on, and Hueflask holds none, so there is nothing for us to send, correct or delete on your behalf. If you would like that confirmed in writing for your own records, ask and we will send it.
Your progress is yours alone to remove. Reset it inside the game, clear the app's data in Android settings, or uninstall Hueflask — the file goes with it. None of that needs our involvement, and no copy is left behind, because no copy was ever made.
Complaints can go to the UK Information Commissioner's Office at ico.org.uk, though we would rather you wrote to us first so we can explain or fix whatever prompted it.
This page is updated only when the game changes in a way that affects privacy, and the date near the top changes with it. Builds you have already installed keep behaving exactly as they do today.
Questions about this policy, a level that looks unsolvable, or a hint that misfires: harbour@sparxelectrical.lol. One inbox, read by the person who wrote the game, usually within a couple of days.
This policy covers the Android application Hueflask (com.sortwell.hueflask) and no other software.
