Gnosis is a liturgical calendar application for Orthodox and Catholic Christians developed by Giangerostudio. We believe your faith and devotional practice are deeply personal. Core devotional records stay on your device. Optional online features and advertising use third-party services as described below; advertising may involve device identifiers and ad interaction data.
This Privacy Policy explains what data the Application accesses, how it is handled, and your rights under global privacy frameworks including the General Data Protection Regulation (GDPR).
For the core calendar features, Gnosis does NOT collect, store, or transmit any personal data to our own servers. There is no account creation, no login requirement, and no profile tracking.
All user preferences and personal liturgical records are stored strictly locally on your device, including:
These locally stored devotional records are not supplied to the advertising SDK by Gnosis. Operating system-level device backups may include local app data. Advertising and other online services handle separate data as described below.
If you voluntarily choose to use the interactive "Word of God AI" feature:
When you purchase or light a Virtual Candle in Gnosis:
The upcoming Android version 7.1.0 includes Google AdMob for one banner below the homepage news. Earlier versions do not contain this advertising integration. Development builds use test ads; live advertising is enabled separately.
Gnosis applies Google's most restrictive CHILD age treatment to every ad request, regardless of the user's age. We do not ask for or store an age or date of birth for advertising. This treatment disables personalized ads, remarketing, third-party ad-vendor requests and transmission of the Android advertising ID. The app also removes advertising-ID and Android AdServices/Topics permissions from its manifest. Restricted ads may still involve processing of IP address (including approximate location), ad interactions and diagnostic information for ad delivery, measurement and fraud prevention; this is not a zero-data service.
Gnosis does not send your saved prayer reminders, bookmarks, family names or calendar-tradition preferences as advertising targeting parameters.
We also set the separate under-age-of-consent signal in Google's User Messaging Platform. Google suppresses its European consent request for that signal; we do not use suppression to request personalized ads. Requests still wait until the platform permits them. If Google requires a privacy-options entry, it appears in Settings → Advertising privacy. Reading and news remain available when advertising is unavailable.
See How Google uses information for advertising and Google's SDK data disclosures. Google's published age-treatment restrictions describe the protections applied to these requests.
Gnosis uses device permissions for reminders, online content and supported app features. Versions with AdMob also include SDK permissions for network status and advertising identifiers:
| Permission | Purpose |
|---|---|
Internet (android.permission.INTERNET) |
To fetch public liturgical content, handle user-initiated Google AI Search queries, and load advertising/privacy messages in versions with advertising enabled. |
Post Notifications (android.permission.POST_NOTIFICATIONS) |
To deliver local alerts for saints' days, fasting alerts, and name day commemorations. |
Schedule Exact Alarms (android.permission.SCHEDULE_EXACT_ALARM) |
To trigger feast and prayer notifications at the precise local time selected by the user. |
Receive Boot Completed (android.permission.RECEIVE_BOOT_COMPLETED) |
To restore your scheduled local feast notifications after you restart your mobile device. |
Vibrate (android.permission.VIBRATE) |
To enable haptic vibration when a scheduled feast reminder alerts. |
Advertising ID (com.google.android.gms.permission.AD_ID) | Explicitly removed from Gnosis's manifest in the restricted advertising configuration. Android advertising-ID transmission is also disabled by the SDK's CHILD age treatment. |
Gnosis maintains a strictly privacy-focused stack. Specifically:
Gnosis is intended for a general audience and is not specifically directed at children. A general-audience ad content rating is used to restrict inappropriate creatives; it is not age verification. If you believe a child's personal information has been processed inappropriately through the app, please contact us using the details below.
Under the General Data Protection Regulation (GDPR) and other applicable privacy regulations, you have rights regarding your personal data. Because Gnosis stores your settings and data locally on your device:
For information processed by Google advertising services, use the Google privacy controls linked above. Clearing Gnosis's local storage does not itself delete data already held by Google. Contact us with privacy requests or concerns.
We may update this Privacy Policy periodically to reflect technological improvements or regulatory updates. Any changes will be published immediately on this webpage with a revised "Last Updated" date.
