Privacy policy
Effective October 28, 2026
Oratório is a prayer app with the Liturgy of the Hours and the daily Mass readings, made by Emerson Lima. This policy explains what data the app uses, why, and what you can ask for.
Who is responsible
Emerson Lima, who develops Oratório. Contact: contato@merzdev.com.
What stays on your device
- Your settings (text size, colors, language, calendar country), the optional memorials you choose and your reminders.
- This data is stored only on your device. It is not sent to us or to third parties, and it is deleted when you uninstall the app.
- If your phone backup is on (Google on Android, iCloud on iPhone), the system itself may include these settings in your account’s backup. That backup is yours: we have no access to it.
Reminders
Reminders are scheduled by the phone itself, with no server and no internet. The app asks for permission to show notifications and, on Android, to reschedule reminders when the phone restarts.
Purchase check (Google Play version)
Because Oratório is a paid app, the version installed from Google Play checks the purchase the first time it opens and then every 30 days. To do this:
- the app asks Google Play for an attestation (Play Integrity) that this copy came from the store and was bought by the account on the device;
- the attestation goes to an Oratório server (Google Cloud, São Paulo region), which checks it with Google and answers only “yes” or “no”;
- none of this includes your name, email, contacts, location or anything about your prayer, and the server does not store the result;
- as with any internet request, Google Cloud keeps technical logs (such as IP address and time) for up to 30 days, for the operation and security of the service.
This is done only so that the paid app is used by those who bought it. The legal bases are the performance of the purchase contract and the legitimate interest in preventing unauthorized copies. Google Play handles your account and device data according to the Google Privacy Policy.
On iPhone, the purchase is made and checked by the App Store, and the app does not make this request.
What the app does not do
- No sign-up or account.
- No ads, analytics, tracking or cookies.
- No selling or sharing of data with anyone.
Your rights
Under Brazil’s data protection law (LGPD) and, in the European Union, the GDPR, you can ask to access, correct or delete your data and ask questions about how it is handled.
Since the app keeps no personal data of yours on any server, there is no record to look up or delete: to delete the app’s data, just uninstall it. Google Cloud’s technical logs are deleted automatically within 30 days.
For any request, write to contato@merzdev.com. You may also contact the data protection authority where you live.
Children
The app is not directed to children under 13 and does not collect personal data from anyone.
This website
This page uses no cookies, ads or visitor analytics. The hosting provider (Vercel) keeps technical access logs, such as IP addresses, for the operation and security of the site.
Changes
If this policy changes, the new version will be posted on this page with its date.
