Brasslight Slots: Casino — Privacy Policy
Last updated 10 September 2026
The short version
Brasslight Slots: Casino is a free game with no ads or in-app purchases. It stores game progress and first-party usage events to understand whether visits are enjoyable and players return. It does not sell your data or share it with advertisers. You can play without linking a Google or Apple account.
Who is responsible
This app is published by an independent developer, Michael Orlov. For anything in this policy, write to micorlov@gmail.com.
App: Brasslight Slots: Casino (com.catslots.cat_slot_machine).
What the app stores
On your device only
Your progress — fish balance, level, unlocked cats, album trinkets, streak, missions, sound and motion settings — is saved locally on your phone. Parlour visit progress, keepsakes, display choices and reminder preferences are also saved locally. When Firebase is available, an anonymous account backs up keepsakes and uploads usage events. Linking Google or Apple is optional. Local reminder schedules stay on the device.
On our servers (Google Firebase)
| Data | Why |
|---|---|
| Account identifier | To recognise your save across sessions. Anonymous by default — a random ID with no name attached. |
| Display name | Shown next to your score on the leaderboards. Taken from your Google or Apple account name if you sign in, otherwise your chosen cat's name. |
| Email address | Held by Firebase Authentication only if you choose to sign in with Google or Apple, so the same account can be restored later. It is never shown to other players. |
| Game progress | Fish balance, level, and hourly / daily / weekly points, so the leaderboards can be ranked. |
| Parlour keepsakes | Private visit progress, grant dates, owned keepsakes and display choices, to restore your collection across devices. |
| Visit measurement | A random installation identifier, experiment group, first-use time, session start and duration, visit steps, collection events, reminder choices and optional enjoyment ratings. These are private and used to compare return visits and experience quality, not to infer mental health or target advertising. |
| Invite code | An eight-character code so a friend's invite can credit you both. |
| Notification token | A Firebase Cloud Messaging token per device, plus which notification categories you have switched on, so the app can tell you a friend joined or your rank changed. Only stored if you allow notifications. |
What the app does not collect
- No advertising identifiers and no ad networks — the game shows no ads.
- No third-party analytics SDKs. First-party usage events are described above.
- No location, contacts, photos, microphone or camera access.
- No payment information — there are no in-app purchases, and the in-game fish have no cash value and cannot be bought, sold or exchanged for anything outside the game.
Who else sees it
Data is stored using Google Firebase (Firebase Authentication, Cloud Firestore and Firebase Cloud Messaging), which processes it on our behalf. See Firebase's privacy documentation.
Your display name, cat and score are visible to other players on the in-game leaderboards. Nothing else is.
We do not sell your data, and we do not share it with advertisers or data brokers. We would disclose it only if legally required to.
Security and retention
All traffic between the app and Firebase is encrypted in transit with HTTPS/TLS. Database rules restrict every player document so it can only be written by the account that owns it.
Your data is kept while your account exists. If you ask for deletion, it is removed within 30 days.
Deleting your data
To have your account and all associated data erased, email micorlov@gmail.com from the address you signed in with, or follow the instructions at cat-slot-machine.web.app/delete-data.html.
Deleting the app from your phone erases everything held locally on that device.
Children
Brasslight Slots: Casino depicts a slot machine. It is a simulated-gambling game intended for adults, it is not directed to children, and it is not part of any families or kids programme. We do not knowingly collect data from children. If you believe a child has provided us with personal information, write to us and we will delete it.
Your rights
Depending on where you live, you may have the right to access, correct, export or delete the personal data we hold about you, and to object to its processing. Email micorlov@gmail.com and we will respond within 30 days.
Changes to this policy
If this policy changes, the revised version will be posted at this address with a new "last updated" date. Material changes will also be announced in the app.
