This is how stock Android 16 shows it; menu names vary by Android version and phone maker.
Know your way around APKs? aapt2 dump permissions does not list android.permission.INTERNET. You will see USE_BIOMETRIC and USE_FINGERPRINT: they power the fingerprint lock, Android grants them without asking, and they give no network access.
An honest note: if Android backup is turned on, the system saves your apps’ data to your Google account, Cashflow’s included. That is what lets you get it back on a new phone, and you can turn it off in Android settings.

Export a backup from Settings and import it on another phone. Already using Cashflow on the web? If its Settings show “Exportar copia para la app”, export the backup there and import it into the app.
An optional plan for those who need more. We are working on:
Yes, and ad-free. The free plan includes one personal profile, one business profile, reports and CSV export. An optional premium plan will come later.
Android asks because the app does not come from Google Play. Once you are done, you can turn that permission off again.
Download the new version from this page and install it over the one you have, without uninstalling it. Android keeps your profiles, categories and transactions because both versions are signed with the same key.
Uninstalling Cashflow deletes its data from the phone. If you ever need to, export a backup from Settings first.
Compare its SHA-256 fingerprint with the one we publish next to the download button. On a computer, for example: sha256sum cashflow-1.2.0.apk. If both strings match character for character, the file arrived intact.
To check who signed it: apksigner verify --print-certs cashflow-1.2.0.apk must show, as the certificate’s SHA-256 digest, the one we publish next to the download (apksigner prints it in lowercase without colons: 091e7f13ec3a320d36da00805624584929b224a25b8779c6e1fed6a6414aceeb). Every future version will be signed with that same key.
There is no iPhone version yet. If you already use Cashflow on the web, the web version keeps working as always.
In Settings, export a backup and keep it wherever you like. On the new phone, install Cashflow and import that backup: your profiles, categories and transactions come back as they were. Importing replaces whatever was on that phone, and the app asks you first.
Yes, it is on its way. In the meantime, you can install it from here.
Free, no accounts and no ads. Installs in a minute.

Every future version of Cashflow will be signed with this same key; Android only installs an update if the signature matches.
