Privacy Policy

Effective date: November 4, 2026

This policy explains what information Glass, the stained-glass puzzle game by Fountain Interactive Ltd (“we”), collects, why, and what you can do about it.

At a Glance

• No accounts. We never ask for your name, email address, phone number or contacts.
• No ads, no advertising SDKs, no advertising identifier (IDFA), and no tracking across other companies’ apps or websites.
• No location. We do not collect GPS location, and we turn off location lookup from your IP address in our analytics.
• Only if you tap Allow when Glass first opens, we collect anonymous usage and purchase events, tied to a random identifier for your copy of the app, so we can fix problems and improve the game. You can turn this off at any time in Settings.
• We do not sell your data or share it with anyone for advertising.

Information Stored on Your Device

Your progress, completed puzzles, settings, unlocked packs, hint balance and preferences are stored on your device. Deleting the app deletes them. Purchases can be restored through the App Store or Google Play.

Information We Collect

The first time you open Glass, it asks whether you are happy to share anonymous usage data. Nothing below is sent unless you choose Allow. If you choose No thanks, the game works the same and sends us none of this. You can change your mind at any time with Settings → Share usage data; turning it off stops collection and deletes the identifier and any unsent events from your device.

If you allow it, Glass sends us:

• An app identifier: a random ID created when Glass is first opened (and, on Apple devices, Apple’s per-developer identifier for vendor apps). It is not linked to your name, Apple ID or Google account, and it is not the advertising identifier.
• Gameplay and usage events: for example, puzzles started and completed, tutorial steps, hints used, settings changed, and screens or offers viewed.
• Purchase events: which product was viewed, bought or restored, its price and currency, and whether the purchase succeeded.
• Technical details: app version, build number, platform (for example iOS or Android) and engine version.

We use this to understand how the game is played, find puzzles that are too hard or broken, test changes to the game (some players may see a different version of a feature), and confirm that purchases work. We do not use it to identify you, and we do not combine it with data from other companies.

Purchases and Platform Services

In-app purchases are handled by Apple or Google. We never see your payment card or billing details. Apple and Google tell Glass which products you own so that they can be unlocked and restored.

If you use Game Center or Google Play Games, achievements are reported to that service under its own privacy policy. If you allow notifications, Glass schedules a reminder on your device when a free daily hint is ready; this is done locally and sends no information to us. If you choose to save a picture of a finished window, Glass only adds that image to your photo library and cannot read your other photos.

Service Providers

We use PostHog (product analytics) and Supabase (event storage and game experiments) to receive the information described above. They process it only on our behalf and under data processing terms. Their servers are in the United States; where data is transferred from the UK or EEA, it is protected by the UK International Data Transfer Addendum and the EU Standard Contractual Clauses.

Legal Bases

For players in the UK and EEA, we rely on performance of a contract to run the game and provide purchases, and on your consent, given in the app, to collect the analytics described above. You can withdraw consent at any time in Settings; this does not affect collection that took place before you withdrew it.

Retention

Analytics and event records are kept for no longer than 12 months, except where a longer period is required for purchase, fraud-prevention, tax, accounting or legal reasons.

Your Choices and Rights

Depending on where you live, you may have the right to access, correct, delete, restrict or object to the processing of your data, and to complain to your data protection authority (in the UK, the Information Commissioner’s Office). Because we do not know who you are, we may ask you for your app identifier, which we can help you find, so that we can locate your records.

To make a request or ask a question, email support@fountaininteractive.com. Turning off Share usage data in Settings, or deleting Glass from your device, ends collection and resets its random identifier.

Children

Glass is a general-audience puzzle game. It has no chat, no accounts and no ads, and we do not knowingly collect personal information from children.

Changes

If we change this policy, we will post the new version on this page and update the effective date.
