This privacy policy applies to the The Lost Grimoire app (hereinafter referred to as "Application") for mobile devices, created by Dairon Vilaú / DaironApps (hereinafter referred to as "Service Provider") as a free service. This service is intended for use "AS IS".
All game progress (current level, Runes balance, owned and equipped cosmetic backgrounds) is saved locally on your device only, and is never sent to the Service Provider.
The Application displays advertisements through a third-party service (see "Advertising" below), which automatically collects certain device information as described in that section. The Application does not use Artificial Intelligence (AI) technologies to process your data or provide features.
The Application uses Google Mobile Ads (AdMob), a service provided by Google LLC, to display advertisements, including rewarded video ads that grant in-game currency (Runes) in exchange for watching them.
To serve and measure these ads, the Google Mobile Ads SDK automatically collects and shares the following information with Google: IP address (used to estimate general device location), device and account identifiers (including the Android Advertising ID and App Set ID), diagnostic and performance information, and interactions with ads and the Application (such as app launches, taps, and video views). This data is used for advertising, ad measurement/analytics, and fraud prevention purposes.
This data is transmitted securely (encrypted in transit) to Google. For more information on how Google collects and uses this data, see Google's Privacy Policy and "How Google uses information from sites or apps that use our services".
You can reset or opt out of the use of your Advertising ID for personalized ads at any time through your device settings (on Android: Settings > Privacy > Ads), or manage your ad personalization preferences at adssettings.google.com.
The Application offers optional in-app purchases (such as Rune packages and premium cosmetic backgrounds) using real money, processed entirely through Google Play's billing system. The Service Provider does not receive, collect, or store your payment card details - these are handled directly by Google Play in accordance with Google's Privacy Policy.
The Application shares data only with the third-party services listed above (Google Mobile Ads / AdMob, and Google Play's billing system for in-app purchases). No other third-party analytics, advertising, or data collection services are used, and no other information is transmitted to external services.
The Application is not directed at children under the age of 13 and is not designed to appeal primarily to children. The Service Provider does not knowingly collect personal information from children. If you believe a child has provided personal information through the Application, please contact the Service Provider using the information below.
Game progress is stored locally on your device and is not transmitted anywhere. Data collected by the third-party advertising and billing services described above is transmitted using industry-standard encryption (TLS).
This Privacy Policy may be updated from time to time for any reason, for example if new features are added to the Application in the future. The Service Provider will notify you of any changes to the Privacy Policy by updating this page with the new Privacy Policy. You are advised to consult this Privacy Policy regularly for any changes, as continued use is deemed approval of all changes.
This privacy policy is effective as of 2026-07-09, and was last updated on 2026-08-08.
If you have any questions regarding privacy while using the Application, please contact the Service Provider via email at vilaudairon@gmail.com.
