Privacy Notice
The short version: Miaulodía doesn't ask you for an account, an email, or a password. What you write stays on your phone. On the free plan, your text only leaves it if you choose to use one of your surprises; otherwise, the app picks the song on the phone itself. With Plus it leaves every time you write, and also when generating narrative arcs, the weekly playlist, or a guided session. Guided sessions are not stored anywhere.
Who is responsible
Daniel Ortiz, an individual, is responsible for the handling of personal data related to the Miaulodía app.
Contact for any privacy matter: miaulodia.app@gmail.com
Miaulodía is available in Mexico, the United States, Canada, and countries across Latin America and the Caribbean. This notice applies to everyone; specific sections for certain regions appear below.
What data is handled, and where it lives
What stays on your device
All of the following is stored only on your phone, in the app's private storage, protected by the phone's own encryption. No copy exists on our servers:
- Your journal text, whether you type it or dictate it with your voice
- The mood and energy level you select
- The name you choose at the start, if you enter one
- The songs the app recommended and your votes on them
- Your preferences: language, music language, cat appearance, reminders
- Any narrative arcs and weekly playlists generated for you
- The support notes your cat has sent you
We have no way to read any of it. Delete the app and it goes with you.
What leaves your device
When the AI is involved, what it needs to respond is sent to our intermediate server (Cloudflare) and from there to Anthropic, which picks from the songs in our catalogue and writes the note that goes with them. For your songs, that is your entry text and your mood; for narrative arcs, your recent entries; for the weekly playlist, how you felt each day; and for a guided session, the conversation. It is sent without your name and without any identifier of your device. As with any internet connection, the server receives your IP address in order to respond and to prevent abuse; we don't use it to identify you.
On the free plan, this only happens if you choose to use one of your surprises; otherwise, the app picks the song on the phone itself and your text doesn't leave it. With Plus it happens every time you write, and also when generating narrative arcs, the weekly playlist, and guided sessions.
Guided sessions are not stored. The conversation travels so your cat can answer, but neither what you write nor its replies are kept: not on your phone, not on any server. Close the session and it's gone.
Risk detection happens inside your phone. So the app can offer you helplines when needed, it compares what you write against a list of risk phrases. That comparison sends nothing to any server, and leaves no record that it happened.
To play the 30-second sample, Apple's public search service is queried with the song title and artist. What you wrote is never sent.
The stickers you win by playing are handed to WhatsApp only when you tap «Add to WhatsApp». They are pictures of the cat, the same for everyone: they carry nothing of yours. From then on they live in your WhatsApp and are governed by its terms.
What never happens
- No ads
- No tracking or advertising profiles
- No usage analytics or statistics about you
- Your information is never sold or shared with anyone
- No account, email, phone number, or password is requested
What it's used for
Only to make the app work: saving your journal, showing your history, and picking songs for you. There is no secondary purpose.
Transfers
When you use AI, your text passes through two providers located outside your country:
- Cloudflare, Inc. — carries the request. Does not store it.
- Anthropic, PBC — picks from the songs in our catalogue and writes the note that goes with them.
Under Anthropic's commercial terms applicable to API use, submitted content is not used to train their models, and inputs and outputs are deleted from their systems within 30 days. If their automated trust and safety systems flag content for possible breach of their usage policy, that content may be kept for up to 2 years, and the scores of that classification for up to 7 years.
There are no other transfers.
Purchases
The Miaulodía Plus subscription is processed entirely through the app store you installed the app from. Your payment details are handled by that store and we never see or receive them. The app only checks whether your subscription is active.
Your rights
Because of how Miaulodía is built, you exercise most of these rights yourself, immediately, without asking us or waiting for a reply:
- Access: your full history is in the app, and you can export it from Settings.
- Correction and deletion: you can edit or delete any entry, and erase your whole journal from Settings.
- Objection: you can use the app without AI; then nothing leaves your device.
- Withdrawing consent: uninstalling the app removes all your data from the phone.
To exercise any right regarding data temporarily transmitted to the providers named above, or for any question, write to miaulodia.app@gmail.com.
Children
Miaulodía is not directed to children under 13 and does not knowingly collect personal information from them. The minimum age of use is 16, as stated in the terms.
United States · California residents
If you reside in California, state law gives you the right to know what personal information is collected about you and why, to request its deletion, to correct it, and not to be discriminated against for exercising these rights.
Miaulodía does not sell or share personal information in any sense — including targeted behavioral advertising — so there is no opt-out to offer you: it simply doesn't happen.
Because your information is stored on your own device, you can view, correct, and delete it from the app at any time. For any other request, write to the address above.
Canada
If you reside in Canada, you have the right to access the personal information held about you, request its correction, and withdraw your consent at any time, under applicable federal law.
If you have a concern about how your data is handled, please write to us first at the address above. If our response doesn't satisfy you, you may file a complaint with the Office of the Privacy Commissioner of Canada.
Mexico
If you reside in Mexico, you have the right to access, rectify, cancel, or object to the processing of your personal data (ARCO rights), and to withdraw your consent, under the Federal Law on Protection of Personal Data Held by Private Parties. Requests are handled at the email address above, within the timeframes set by law.
If you believe your right to data protection has been violated, you may turn to the Secretaría de Anticorrupción y Buen Gobierno, the competent authority.
Latin America and the Caribbean
If you reside in any other country where Miaulodía is available, you have the access, correction, deletion, and objection rights described above, and can exercise them the same way: from the app itself or by writing to the address above. If your country has a data protection authority, you may turn to it.
Minimum age
Miaulodía is rated 16+ and is not directed at anyone below that age. We do not knowingly collect information from people under that age.
Security
Your data is stored in the app's private storage, protected by the phone's own encryption. Communications with our servers and providers travel encrypted over HTTPS. The credentials for the AI services are not inside the app: they live on the server, precisely so they cannot be extracted from the phone.
Changes to this notice
If this notice changes, the updated version will be published at this same address with its date. Significant changes will also be announced inside the app.
