Kansas IA Financeira

Privacy policy

Last updated September 20, 2026

In one sentence: Kansas stores your account, your money data (transactions, accounts, goals) and the statement/invoice files you send for reading on our server, so it can show the numbers and answer your questions. We never sell it, there are no ads, and you can delete everything from inside the app.

1. Who is responsible

Fábio Silva, independent developer of Kansas IA Financeira (com.pulsefinanceiro.dreai). Privacy contact: fabiokansas@gmail.com.

2. What leaves your device and is stored on the server

Data	Why	Where
Name, email and account ID	Sign in and link your data to your account	Firebase Auth and Firestore
Your money: transactions, accounts, cards, budgets and goals	Show balance, forecast and analysis, and answer your questions	Firestore
Files you send for reading: PDF and OFX/CSV statements or invoices, and receipt photos	Extract the transactions and sort them by category	Cloud Storage, in your account's folder
Chats with Kansas and its memory (goals, decisions)	Continue the conversation and remember what you told it	Firestore — memory is only on if you accept it
Daily and monthly AI usage counters	Enforce your plan's quota and block abuse	Firestore
Subscription purchased on Google Play (order/token)	Unlock the paid plan and check it is active	Firestore + Google Play

3. What never leaves your device

Your calendar. When you turn on due-date reminders, the app creates the event in your phone's own calendar. The server only stores whether the feature is on and which calendar you picked — no events, guests or notes.
Your camera and photos. Nothing is uploaded just for being on the device. A photo only travels when you pick it and ask for an import.
Your location, contacts and browsing history. The app never asks for them.

4. Who else processes this data

Kansas runs on Google services, which process the data on the app's behalf under their own contracts:

Firebase (Authentication, Firestore, Cloud Storage, Cloud Functions) — account, data and files.
Google Gemini — your chat, the figures in your summary and the memory you authorised are sent to produce Kansas's answer. We use the paid API tier; on that tier Google does not use the submitted content to train models.
Google Cloud Vision — reading text from invoice and receipt images.
Google Play Billing — the subscription purchase. Payment is handled by Google; the app never sees your card number.

We do not sell or share your data with advertisers, data brokers or commercial partners. The app has no advertising.

5. Security

Everything travels over HTTPS.
Database rules only let each account read and write its own data.
Calls to the server go through app attestation (App Check).

6. How long we keep it, and how to delete it

Data is kept for as long as your account exists.
In the app: Settings → Delete account. This erases the login, the profile, the transactions, the chats, the memory and the statement and invoice files you uploaded.
Without the app: email fabiokansas@gmail.com from the account's address. We answer within 30 days. See also the deletion page.
Kansas's memory can be switched off and wiped on its own, in Settings, without deleting the account.
Purchase records that the law requires to be kept stay with Google Play, not with us.

7. Your rights

Under the GDPR and Brazil's LGPD you may request access, correction, deletion, portability of your data and withdrawal of the memory consent. Use the app or write to fabiokansas@gmail.com.

8. Children

The app is not directed to people under 18 and does not knowingly collect children's data.

9. Changes

If the app starts collecting anything new, this page and the Data safety form on Google Play are updated before the change reaches you.
