Oviedo Studio / MarianaLee / Privacy policy
Privacy policy
Effective November 3, 2026.
In short
- MarianaLee does not collect, send or share personal data about you or about children.
- It has no ads, no analytics, no third-party tracking, and it does not ask you to create an account.
- It works without internet. Only the optional purchase of the full library needs a connection, and Google Play handles it.
Who provides it
MarianaLee is a storytelling app for reading together. It is provided by Oviedo Studio. To write to us, use "Help and contact" in the app settings or write to oviedostudio.app@gmail.com.
The microphone
Inside a story, in "With my voice" mode, the app uses the microphone to follow your reading aloud and play sounds on the right word. Recognition happens on the phone itself, with an open-source engine (Vosk). Audio is not recorded, what is said is not stored, and nothing leaves the phone. If you do not grant permission, you can read in "Tap" mode and the app works the same. You can remove the permission at any time in the phone settings.
Buying the full library
Some stories are included for free and the rest unlock with an optional one-time purchase. The purchase is made through Google Play and the Google account on your phone: Google processes the payment, and we do not see or store your card, your name or your email. The app only asks Google Play whether the purchase exists, to unlock the stories and for "Restore purchase". That connection is made by Google Play and is governed by Google's privacy policy. The purchase is made by an adult, behind an adult gate inside the app. If you do not buy, the app works the same with the free stories.
What is stored on your phone
Only what is needed for the app to remember your preferences:
- The page you are on in each story.
- Your settings: language, volumes, night mode, motion and animations.
- That you have seen the welcome and confirmed that an adult will supervise use.
- Whether the full library is unlocked on this phone.
This data stays on your phone and is deleted when you uninstall the app or clear its data in the phone settings.
Children
MarianaLee is for a mother, father or guardian to read with young children. We do not ask for or store the names, ages, photos or any other data of children. The age shown on each story is a guide to the story, not data about the child.
Third-party services
The app does not use third-party services that receive information about you or about children: it has no advertising, analytics or accounts. The only exception is Google Play, which handles the optional purchase as explained above. Sounds and illustrations are inside the app and their credits are in "About" > "Credits".
Future changes
If the app ever adds accounts or more internet connections, we will update this policy first and tell you inside the app. Nothing that collects data will be turned on without telling you beforehand.
Your rights and contact
Since we do not collect data, we hold no data about you to access, correct or delete. Purchase data is held by Google; to ask about it, use your Google account. If you have questions about this policy, write to us from "Help and contact".
