Privacy Policy
Last updated 21 August 2026
This explains what Glimmer Groove collects, why, and what you can do about it.
Who we are
Glimmer Groove is published by Tekin Dabaj, Famagusta, Cyprus. For the purposes of the UK and EU General Data Protection Regulation, we are the data controller for the information described here. You can reach us at arcadetkn@gmail.com.
What we collect, and why
We have tried to make this specific rather than exhaustive-sounding. If something is not in this table, the game does not collect it.
| What | Why | When |
|---|---|---|
| An anonymous account identifier, generated by Firebase Authentication | So your progress can be saved to our servers and restored on a new device. It is a random string. It is not linked to your name, email or phone number unless you choose to link a sign-in account. | First launch |
| Your game progress — which glades you have finished, your best moves and times, hearts, streak, in-game currency ledgers, the grove you have built, and your settings | So the game can continue where you left off, and so the same progress appears on your other devices. | As you play |
| A public grove card — the keeper name you chose, your grove score, and where things stand in your grove | So other players can see your grove on the boards. This is the only information other players can see, and you can switch it off in the settings screen at any time, which removes your card. | Only if the boards are enabled |
| Your chosen keeper name, held as a reservation so two players cannot claim the same one | To keep names unique. You choose this name; please do not use your real name if you would rather it were not public. | If you set a name |
| A linked sign-in — an identifier from Apple or Google, and whatever that provider passes to us | Only if you choose to link an account so your progress survives losing your device. We do not receive your password. | Only if you link |
| Purchase records — the store transaction identifier and what was bought | To confirm a purchase with Apple or Google and to give you what you paid for, once. We never see your card details — the payment happens inside the store, not inside the game. | If you buy something |
| Advertising identifiers and related data, handled by our advertising partners | To show adverts and to pay for the game being free. See Advertising below. | When adverts are shown |
| Basic technical information — device model, operating system version, language, and error diagnostics | To find out why something crashed or a screen drew wrongly on a device we do not own. | As needed |
What we deliberately do not collect
- Your name, unless you type one in as your keeper name.
- Your email address, unless you email us or link a sign-in account.
- Your contacts, photos, microphone, camera or precise location.
- Your payment card details. Those never reach us.
Our legal bases (UK and EU)
- Performance of a contract — saving and restoring your progress, and honouring a purchase. Without these the game does not work.
- Consent — personalised advertising, and appearing on the public boards. Both are optional and both can be withdrawn.
- Legitimate interests — keeping the game working, diagnosing crashes, and preventing fraud and abuse of the in-game economy.
- Legal obligation — keeping records of purchases for tax and accounting.
Advertising
The game is free, and adverts are how it is paid for. Adverts are optional in the sense that matters: there are no forced adverts between levels. Every advert in Glimmer Groove is one you choose to watch in exchange for something.
Adverts are delivered by Unity LevelPlay (ironSource) as the mediation platform, and by the advertising networks it works with, which currently include Unity Ads and Google AdMob. These partners are independent controllers of the data they collect and have their own policies:
- Unity — player and app user privacy policy
- Google — how Google uses information from sites or apps that use our services
Your choice, and how to change it
If you are in the European Economic Area or the United Kingdom, you are asked before any personalised advertising happens, through a Google-certified consent form. If you decline, you will still see adverts and still receive the rewards for watching them — they will simply not be based on a profile of you.
You can change your answer at any time: open Settings in the game and choose Privacy & ad choices.
On iOS, you are separately asked whether the app may use the device advertising identifier. That answer belongs to the operating system and can be changed in iOS Settings › Privacy & Security › Tracking.
Who your data is shared with
We use a small number of providers, each for one job:
- Google Firebase (Authentication, Cloud Firestore, Cloud Functions) — the anonymous account and the saved progress. Data is stored in the European Union.
- Apple and Google — app distribution, payments and purchase verification.
- Unity LevelPlay and its advertising networks — advertising, as described above.
We do not sell personal information, and we do not share it for cross-context behavioural advertising beyond what the advertising partners above do with your consent.
International transfers
Our save data is held in the European Union. Some of our providers are based in the United States and may process data there, relying on the European Commission’s standard contractual clauses or an equivalent safeguard.
How long we keep it
- Saved progress — for as long as the account is in use, and for up to 24 months after it goes quiet, after which it may be deleted.
- Your public grove card — until you switch the boards off or delete your data, whichever comes first.
- Purchase records — for as long as tax and accounting law requires, which is generally seven years. These survive deletion of your game data, because we are not permitted to destroy them.
Your rights
If the UK or EU GDPR applies to you, you have the right to ask for a copy of your data, to have it corrected, to have it deleted, to restrict or object to how we use it, and to withdraw consent you have given. Similar rights exist under the California Consumer Privacy Act and other laws.
The quickest routes are in the game itself — the boards opt-out is in Settings, and so is the advertising choice. For anything else, or to delete everything, see deleting your data or write to arcadetkn@gmail.com. We answer within 30 days.
Because accounts are anonymous by default, we may need you to prove which account is yours before we act on a request — usually by sending the request from a linked sign-in address, or by giving us the account identifier shown in the game.
If you think we have handled your data badly, you can complain to your national data protection authority.
Children
Glimmer Groove is a general-audience game. It is not directed at children under 13, and it is not registered as a child-directed app with our advertising partners. We do not knowingly collect personal information from children under 13. If you believe a child has given us information, write to arcadetkn@gmail.com and we will delete it.
This website
This site is static. It sets no cookies, runs no analytics, and does not track you. The only thing it knows about you is what your browser tells our host in order to send you the page.
Changes
If we change this policy we will update the date at the top, and for anything significant we will say so in the game before the change takes effect.
