Privacy Policy for the game “Glimm” and glimm-game.com

Last updated: 10 November 2026 · Deutsche Fassung (the German version is legally binding) · Legal notice

We are not legally required to appoint a data protection officer. Please send any privacy questions to the address above.

2. Summary

• No account is needed. Progress and settings are stored only on your device.
• Statistics and personalisation stay off until you agree.
• Personalised ads are shown only with your consent.
• The league is optional and can be deleted with all its data at any time in the game.
• We do not sell data and do not build profiles about you outside your device.

3. Consent in the game

On first launch Glimm shows two switches:

• Game statistics: events such as game start, level reached, play time and the test variant you play, without names. We currently use no external analytics service; the events stay on your device. If we add one, we will update this policy first and ask you again where required.
• Personalisation: Glimm calculates on your device when a reminder fits, how likely you are to take a break, and whether you prefer ad videos or offers. This controls how often interstitial ads and offers appear. It never leaves your device, never changes game difficulty and has no legal or similarly significant effect (Art. 22 GDPR).

Both are off until you switch them on, and declining is as easy as accepting. Change your choice any time under Options → Privacy. Google’s consent form (section 5) and, on iPhone, Apple’s tracking prompt ask separately about ads.

4. Data on your device

Glimm stores in your device’s local storage: game progress, levels and stars, sparks, purchased and unlocked content, settings, your consent choices, daily rewards and streaks, a random league ID (only if you join the league) and the last downloaded game settings. This is technically necessary for the game. We cannot access it. Uninstalling the app or clearing browser site data deletes it. Glimm needs no access to contacts, photos, microphone, camera or location. Fonts and music are built into the app.

5. Advertising (Google AdMob)

The free version shows ads provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland: optional reward videos, interstitial ads after some flights and a banner in the menu. Players who bought “No ads” or VIP see no interstitials or banner.

Data: advertising ID (on iPhone only with your permission), IP address, device type, operating system, language, approximate location derived from the IP address, app information and your interactions with ads.

Consent: before the first ad, Google’s consent form (User Messaging Platform, IAB Transparency & Consent Framework) asks for your choice. Personalised ads and the related identifiers are used only with your consent (Art. 6(1)(a) GDPR); otherwise Google shows non-personalised or limited ads. You can change your choice under Options → Privacy and reset the advertising ID in your device settings. More: policies.google.com/technologies/ads. We only see aggregated reports, never data about individual players.

6. Purchases and subscription

Purchases are handled only by the Apple App Store or Google Play; we never receive payment details. To validate receipts and unlock purchases we use RevenueCat, Inc., USA, as our processor: random user ID, receipts, product, price, time, country and device type (Art. 6(1)(b) GDPR). Purchase records are kept as long as needed for unlocking and as required by commercial and tax law (up to 10 years). Subscriptions renew automatically until you cancel them in your store account settings.

7. Reminders

If you allow it, Glimm schedules reminders locally on your device. There is no push server and no push token sent to us. Glimm remembers on the device which texts you open in order to pick better ones. Turn reminders off any time in your device settings.

8. Weekly league (optional)

You join only by entering a nickname and tapping “Join league”. We store your chosen nickname, a random player ID (not linked to your device, advertising ID or any account), weekly points, tier, last week’s result, language and the times you joined and were last active. Your IP address is held in memory for up to one minute for rate limiting and not stored by our software; the host may keep it briefly in technical logs. Your nickname and points are visible to players in your group, so please don’t use your real name. We remove offensive nicknames.

Server: Render Services, Inc., San Francisco, USA, as our processor, data centre in Frankfurt am Main, Germany. Legal basis: Art. 6(1)(b) GDPR. Deletion: any time in the game under Records → League → “Leave league and delete data”, automatically after 12 months without playing, or by email (please include your nickname).

9. Game settings from the internet

On start Glimm downloads a small settings file (for example difficulty values) from glimm-game.com. The values are the same for all players. Your IP address is transmitted to the host for this (Art. 6(1)(f) GDPR).

10. Website glimm-game.com

The website, the browser version of the game and these legal texts are hosted on GitHub Pages (GitHub, Inc., San Francisco, USA). GitHub processes your IP address, date and time, page, browser and operating system to deliver the site and protect it from attacks (Art. 6(1)(f) GDPR). The website sets no cookies and uses no analytics or advertising services.

11. Email

When you email us, we process your address and message to reply (Art. 6(1)(b) or (f) GDPR) and delete it once your request is handled, unless legal retention duties apply.

12. Transfers outside the EU

Google, RevenueCat, Render and GitHub are based in or belong to groups based in the USA. Transfers rely on the EU-US Data Privacy Framework where the recipient is certified, otherwise on the EU Standard Contractual Clauses (Art. 46(2)(c) GDPR).

13. Children

Glimm is suitable for all ages and listed for ages 13 and up. Users under 16 need a parent’s consent for the optional consents. Purchases can be controlled with Apple’s and Google’s parental controls. If we learn that a child created league data without consent, we delete it.

14. Your rights

You have the right of access (Art. 15 GDPR), rectification (16), erasure (17), restriction (18), data portability (20), to withdraw consent at any time with effect for the future (7(3)), and to object to processing based on legitimate interests (21). Write to support@glimm-game.com. Apart from league data and emails we store no data about you; data on your device can be viewed and deleted by you.

You may lodge a complaint with a supervisory authority. Ours is: Die Landesbeauftragte für Datenschutz und Informationsfreiheit der Freien Hansestadt Bremen, Arndtstraße 1, 27570 Bremerhaven, Germany.

15. Changes

We update this policy when the game or the law changes. The version published here applies.
