Luz is a daily prayer companion app. This policy explains what data we handle and why, in plain language. Luz's team is the data controller. You can write to us at imdavidramos@gmail.com.
During setup you can choose a faith tradition so the content fits you. Information about religious beliefs is considered special category data under the General Data Protection Regulation. We process it only with your explicit consent, given when you choose it, and only to personalize the spiritual content you see. You can change or remove this choice at any time. For this reason, Luz is intended for people aged 16 and over.
Some Luz features use Anthropic's artificial intelligence service. In each case, our server sends only what that feature needs:
Prayers, verses, saint information, and the reading library come from curated sources and are shown verbatim: the artificial intelligence never composes them. When you listen to a reflection or prayer aloud, the text is sent to OpenAI to generate the audio. Your intentions, your photos, and your data are not used to train artificial intelligence models and are never sold.
To understand how the app is used and improve it, we record usage events tied to your anonymous identifier, for example which section you open or that you saved an intention. We never record the text of your intentions or your journal content. If the app crashes, we receive a technical error report through Sentry, with device and crash details, so we can fix it. These reports do not include the content of your prayers.
A Circle is a private prayer group you create or join by invitation. What you choose to share in a Circle, such as the group's title and intention, your display name, your messages, your photos, your voice notes, and your prayer reactions (like the Amen), is visible to the other members of that Circle. If you belong to several Circles, the app shows you a combined summary of their activity; this does not change who can see each item: every post remains visible only to the members of its own Circle.
Momentos are public prayer circles, created by the Luz team around an event. When you take part in a Momento, your first name and, if you chose a region, your country's flag can be seen next to your prayer gesture by anyone taking part. Your precise location and your city are never shown. Take part in a Momento only if you are comfortable with that visibility.
In both cases, share only what you want others to see. You can leave at any time. If you report content, we review it within 24 hours and may remove it. See also our Community Guidelines.
You can share photos on your Circle's wall. Photos are kept in private storage and only the members of that Circle can see them, through temporary signed links. They are never on the public internet.
Before publication, every photo goes through an automatic review by an artificial intelligence system, which looks for explicit, violent, or hateful content. If the review rejects a photo, it is not published. This review exists only for safety: the image is not used for any other purpose or to train models.
Photos are deleted when you delete the post and when you delete your account. Share only photos that are yours or of people who have given you their permission.
Luz only uses your location if you ask it to, for the churches-near-you feature. When you use it, the app requests location permission and reads your location once per search. Your coordinates are sent to OpenStreetMap's Overpass API, a community map service, for the sole purpose of getting the list of nearby churches. We do not send your location to our servers, we do not link it to your account, and we do not share it with anyone else. So the search keeps working when the map service is down, the app stores the results on your own phone for seven days, along with the approximate search point (rounded, to about 110 meters). That stays on your device and is removed when you uninstall the app.
Luz may offer faith radio stations. The audio comes directly from each station's servers, is played as is, and Luz does not record or store it. When you listen to a station, your device connects to that station's server, much like visiting its website, so the station can see your IP address. We do not send stations any data from your account.
With your permission, we send reminders and notices about your Circles' activity, for example when someone prays for your intention. To do this we use your device's push token through Expo's service. You can turn notifications off in your phone or app settings; when you delete your account, the token is deleted too.
Subscriptions are processed through your App Store account. We use RevenueCat to manage subscription status. We never see or store your card details.
Only the technical providers that make the app work: Supabase (database, storage, and authentication), Anthropic (the AI reflection and the automatic photo review), OpenAI (the voice), Apple and Google (sign-in), RevenueCat and Apple (subscriptions), Expo (notifications and hosting), Sentry (error reports), OpenStreetMap (the nearby churches search: only the coordinates of that search), and, if you listen to the radio, the station you choose (only your connection to its stream). We do not sell your data. We show no ads and use no advertising trackers.
Some of these providers process data in the United States. By using Luz, you understand that your data may be handled there with the safeguards the law requires.
We keep your data while you use Luz. If you delete a post, its photo or voice note is deleted with it. If you delete your account, we delete your associated data: intentions, journal, Circle content, photos, and push token. Usage events and error reports are kept only as long as needed to improve the app.
You can access, correct, and delete your data, and withdraw your consent at any time. To exercise these rights, use the delete account option inside the app or write to us at imdavidramos@gmail.com.
You can delete your account and all your data from Settings, under Delete account, or by requesting it at imdavidramos@gmail.com.
Luz is intended for people aged 16 and over and is not directed at children under that age.
If this policy changes, we will publish the updated version on this page.
