Nalumo is a self-reflection and introspection app, designed to help you better understand your emotional patterns. This page explains what data we process, why, and what rights you have over it.
Contact details are at the bottom of this page.
When you talk to Nalumo (by typing or by voice), the text of your reflection is sent, at the time of the conversation, to:
This service is an external artificial intelligence provider and has its own privacy policy, which we encourage you to read. The Nalumo server forwards the text in order to generate the reply and does not store the content of your reflections in a database.
If you use voice input, the transcription of sound into text is done by your phone's speech recognition service. Nalumo does not send the audio recording to its servers, only the resulting text.
Your text may describe your emotional state, which means sensitive information. By sending a message to Nalumo you give your explicit consent to this processing. You can withdraw it at any time by stopping use of the app.
Your journal, conversations, pattern map and personal portrait are stored locally, on your device, not on our servers. You can manually export this data, encrypted, at any time, and you can delete it permanently from the app.
If you tell Nalumo how you would like to be addressed, that name is also kept only on your phone and is deleted with the rest of your history. It is sent to the same AI provider, together with your message, only so that Nalumo can address you by it.
To recognise patterns that repeat from one day to the next, Nalumo also sends, together with your message, a short summary of your recent days, with brief excerpts of what you wrote and of Nalumo's replies (taken from your journal on your phone, not your full texts). It goes to the same AI provider, only at the time of the conversation, and is not stored on our servers. You can turn this off, or delete any day, in the app (menu → Nalumo's memory).
If you ask for your personal portrait (menu → My portrait), and only after you confirm each time, Nalumo sends a condensed version of all your saved conversations (brief excerpts of what you wrote and of Nalumo's replies) to Anthropic to write it. It is sent once, only at that moment, and neither the material nor the portrait is stored on our servers. The portrait is saved only on your phone and you can delete it at any time.
None of these services is used by us for advertising.
To check that Nalumo Plus is active, and to prevent abuse of the free service, the app sends the server a random installation identifier (it is not linked to your name or identity: Nalumo has no accounts) and, if you have a subscription, the Google Play purchase token. The server uses the token only to ask Google Play whether the subscription is active, and keeps the result in temporary memory for a few minutes; the identifier is used only to count daily messages and is not stored in a database.
Nalumo does not display ads and does not sell, rent or share your data with third parties for marketing purposes.
Anthropic processes data in the United States. This transfer is necessary for the service to work and takes place only after you have sent a message to Nalumo.
You can access, export or delete your local data at any time, directly from the app. Deleting from the app removes the data stored on the phone; technical data kept by Firebase or Sentry is not deleted this way. For those, as well as for any other request concerning your data (access, rectification, erasure, restriction, portability, objection), you can write to us at the address below. You have the right to lodge a complaint with the National Supervisory Authority for Personal Data Processing (ANSPDCP) in Romania, or with the data protection authority in your country of residence.
Nalumo is intended for people over 18.
Nalumo is a self-reflection tool. It is not a medical service, it does not diagnose, it does not provide treatment, and it does not replace a psychologist, psychiatrist or doctor. If you are going through a hard moment or you are in danger, call 112 or a support line.
We may update this page from time to time. The date of the last update is always shown at the top.
